Which is the best Roomba 2020?

Roomba 2020
Any customer who would decide to purchase a robot vacuum cleaner will inevitably face Roomba models. Being among the market leaders, the brand has an extremely wide model line, numerous patented innovations, and reach history.

Roomba brand belongs to the American iRobot corporation family engaged in the production of robotics. Having started with robots for space exploration and military defense, iRobot needed twelve years to realize that the market of household robotics is vacant and perhaps even more prosperous and promising. Thus, in 2002, the Roomba brand story began, and the world witnessed the first robot vacuum cleaner.

Right from the start, Roomba has been producing robots for dry cleaning only. And for its almost two-decade experience, the company won enormous popularity both among users and experts. By the year 2017, it released almost twenty models and sold over 15 million of products, many of which come with unique functions that no other brand can offer. Moreover, its success provoked the appearance of iRobot Scooba and Braava robots for mopping, Verro pool cleaners, and some others.

Nowadays, such a diversity became a truly controversial issue for us. On the one hand, numerous models provide a wide choice to meet any budget and requirements. But on the other hand, even an experienced user gets lost in such abundancy.

We took the liberty to collect several most popular Roomba models of different functionality, specialization, and price in one article to help you decide on the best option. In the course of the comparison, we will find out their main functions, pros and cons, and will also conclude which robot suits which dwellings and pollutions.

Main Differences Between the Models

We’re going to scrutinize and compare 6 robot vacuum models. They all differ in the year of release, price category, performance, and innovative features, that’s why in the course of our review, you’ll notice lots of differences. To make it easy for you, we’ve collected the crucial ones here. Thus, the following Roombas are different in:

  • Suction: the first iRobot 614 and 675 models from the 600 series produce the minimal 600 Pa suction. Roomba E5 and 960 get 5X higher suction compared to the previous models, while the i7/i7+ vacs are 10X more powerful. Roomba S9/S9+ offer the highest 40X power up to 2200 Pa.
  • Carpet Boost: only Roomba i7/i7+ and S9/S9+ have Carpet Boost technology for improved carpet vacuuming.
  • Brushes: All six models are equipped with dual Multi-Surface floating brushes that adjust their position to the floor height. However, the 600 series 614 and 675 vacuums have one rubber and one bristled roller that are not resistant to hair entanglement. Roomba 960 comes with both rubber anti-tangling rollers with identical blade pattern. The E5 and i7/i7+ bots also have rubber anti-tangling brushes, but each features its unique blade pattern. Finally, the S9/S9+ brush system is identical to the i7/i7+ except that its rollers are 30% longer.
  • Case design: All vacuums have round cases, while the S9/S9+ are the only ones with D-shaped bodies. Also, we notice that their height decreases from 5 inches of 614 to 3.6 in other vacs and up to 3.5 in S9/S9+.
  • Filters: Roomba 614 and 675 are equipped with simpler AeroVac filters without allergen elimination. Others use High-Efficiency filters that collect 99% of particles up to 10 microns and trap pet allergens. The latest Roomba S9/S9+ also have Anti-Allergen sealing.
  • Navigation: The 600 and the E series use iAdapt 1.0 sensor-based navigation only. Roomba 960 is more precise thanks to iAdart 2.0, vSLAM technology with a camera, and Smart Mapping. I and the S series are the best as they work with iAdapt 3.0, vSLAM, and improved Intelligent Multi-Floor Mapping.
  • Multi-Floor Mapping: As we’ve said, Multi-Floor Mapping means that Roomba i7/i7+ and S9/S9+ can remember up to 10 different floor plans. Though Roomba 960 also uses Mapping, it can save one map only.
  • Movement: The 960, the i7/i7+, and the S9/S9+ move evenly in neat rows and never miss spots. Other models apply a semi-random adaptive movement method.
  • Run time: Roomba 614 lasts for 60 minutes. The 675, the 960, and the i7/i7+ run for 75 minutes. The E5 provides a bit longer run time for 90 minutes, while the S9/S9+ are the most durable with their 120 minutes of cleaning.
  • Recharge & Resume: Only Roomba 960, i7/i7+, and S9/S9+ have this automatic recharging and work continuation feature.
  • WiFi: All iRobot models support WiFi and can work with smartphones and smart speakers except for the 614 cleaner. It comes with a remote control.
  • Virtual walls: All six robots are compatible with the Dual Mode Virtual Wall Barrier, but only Roomba 960 comes with it included in the kit.
    Smart Zoning: However, the i and the S series don’t really need any physical virtual walls as they provide Keep Out Zones. It means that here you can draw as many restrictive lines as you wish right on the map. Besides, they use Clean Zones that allow you to set cleaning in definite rooms instead of the whole dwelling.
  • Imprint Link: Only the 900 series and younger robots (i.e., the i7 and the S9) can synchronize with iRobot Braava jet m6 robot mop for comprehensive step-by-step cleaning.
  • Bins and dirt collection: The vacuums differ in bin capacity. Roomba 614 and 675 can contain 300-350 ml; the 960 contains 600 ml; the E5 uses a 500 ml bin; the i7/i7+ and the S9/S9+ have 400 ml bins. Only the i and the S series robots can automatically empty themselves on the base thanks to the Auto Dirt Disposal technology.

Roomba 614

Roomba 614 is one of the earliest Roomba models left in the market. It belongs to the 600 series, and consequently, lacks many modern functions presented in the latest devices. Still, the manufacturer positions it as a nice basic-level robot for pet hair, carpets, and hard floors.

Among the main cleaning advantages, we note a truly efficient brush system capable of dealing with various surfaces and pollutions. The robot uses one side brush and dual Multi-Surface rollers. One of these central elements is rubber, while the other is bristled. Thus, such a combination provides easy dirt loosening and lifting. Rollers automatically adjust to the floor height. They also treat hard floors and the soft pile gently to avoid scratches and damages.
Medium- Pile Carpet for Roomba 614
Though the vacuum does suit all floors, we cannot give it the highest mark because of the weak 600 Pa suction. The 600 series robots don’t provide higher power. Besides, we like the pet hair collection but warn you about often entangling and complicated cleaning of the bristled brush.

Dirt Detection is another plus for the cleaning efficiency. This Roomba patented technology helps the robot determine the most polluted areas and work harder on them. Since the 614 uses old-fashioned sensor-based navigation called iAdapt 1.0 (the first generation), Dirt Detection reduces the possibility of dirt missing. Sensors are aimed at the obstacle and drop avoidance and not at the cleaning improvement.

AeroVac filter eliminates about 85% of particles from the air, which is nice efficiency for such a budget old model. However, if you need an anti-allergen treatment of 100% air sterility, this option is not for you.

When it comes to the run time, the information is quite controversial. The manufacturer states it lasts up to 90 minutes. However, our tests and numerous users’ reviews prove the cleaner operates for an hour or slightly longer. We didn’t manage to watch it cleaning for 90 minutes without breaks. Anyway, it comes with an excellent auto recharging function that significantly improves the situation. It is not Recharge & Resume function yet, so the robot will not automatically continue cleaning after charging.

Being one of the first iRobot products, Roomba 614 doesn’t support WiFi like its younger brothers. You cannot control and schedule the device from your smartphone or via voice commands. Instead, we get a remote control and manual buttons. This is also the reason why the vac supports only few cleaning modes.

Thus, all the above-mentioned factors allow us to conclude that Roomba 614 is still efficient, though discontinuation is quite possible. This is the most affordable iRobot option for $225 only. We do recommend it to the owners of small apartments with combined floors (but only low carpets), pets, and not too full rooms. If you don’t have too complicated requirements and are on a budget, you will find everything you need here.

However, people with large dwellings, including private houses, definitely won’t be satisfied. The vacuum’s too small suction, run time, dustbin, weak navigation without cleaning route building will prevent thorough performance. Please mind that this product will not suit thick carpets.

Pros

  • suitable for hard floors, low carpets, and pet hair
  • compact design
  • dual Multi-Surface Auto-Adjustable rollers
  • Dirt Detection
  • iAdapt 1.0 sensor navigation that protects from dangerous hitting, falling, and breakages
  • AeroVac filter
  • automatically returns to the dock for recharging
  • affordable price

Cons

  • weak suction
  • short run time and no Recharge & Resume
  • small dustbin
  • may tangle hair
  • no WiFi and voice assistant support
  • weak navigation without cleaning routes
  • not suitable for big dwellings
  • not suitable for medium and high carpets

Roomba 675

Roomba 675 is another representative of the 600 series that survived to these days and is still in high demand. The 675 is greatly based on the previous 614 models and, consequently, shares lots of characteristics. But having been released later, it went through several worthy improvements.

Speaking about the things that stayed unchanged, we’d like to note the same 600 Pa suction standard for the whole 600 series and the same dual Multi-Surface Auto-Adjustable rollers. Users will get one rubber and one bristled brush with floating height adjustment for better contact with different surfaces. The system is complemented with one side brush.

Dirt Detection and iAdapt 1.0 sensor navigation result in identical floor cleaning. Roomba 675 deals with all hard floors, low rugs and carpets, collects hair and eliminates challenging spot pollutions in high-traffic areas. However, once again, though the sensor-based adaptive navigation is better than random cleaning, there is enough space for improvements.
Roomba 675 pet hair
Engineers also left the same design, control buttons, and dimensions. Thus, inner parts such as a dustbin and filter avoided changes. The model provides AeroVac filtration that traps the majority of particles and greatly improves the air quality. However, pet owners, parents, and allergic people would need something more powerful.

Roomba 675 can automatically control its charge and return to the dock when it is needed. Once again, the manufacturer claims the 675 vacuum can last for 90 minutes, and this time, it is closer to the truth. The cleaner runs for more than one hour, but only when it uses quiet modes, doesn’t spend energy on entangling wires, overcoming obstacles, etc. We would say it has 75 minutes run time in practice.

Nevertheless, it is WiFi support that became the main revolutionary improvement in Roomba 675. This model is compatible with the iRobot HOME app, which means completely remote control, programming, and even convenient scheduling. You can also connect your vac with Alexa and Google smart assistants for hands-free voice control.

Roomba 675 costs $270. It suits all the same cleaning requirements and conditions described in the Roomba 614 review. You will like it if you’re looking for something budget for a small dwelling with a couple of carpets and pets. Moreover, the WiFi support, schedule feature, and longer run time make it even a more preferable option for modern customers who don’t have time to control the cleaner and are often at work.

Pros

  • suitable for hard floors, low carpets, and pet hair
  • compact design
  • dual Multi-Surface Auto-Adjustable rollers
  • Dirt Detection
  • iAdapt 1.0 sensor navigation that protects from dangerous hitting, falling, and breakages
  • AeroVac filter
  • automatically returns to the dock for recharging
  • more lasting battery
  • compatible with iRobot HOME app, Alexa, and Google Assistant for smartphone and voice control
  • supports cleaning schedule
  • affordable price

Cons

  • weak suction
  • still not quite durable battery and no Recharge & Resume
  • small dustbin
  • may tangle hair
  • weak navigation without cleaning routes
  • not suitable for big dwellings
  • not suitable for medium and high carpets

Roomba 960

As we know, iRobot didn’t stop on the previous series, and after the tremendous success of the 600 and the 800 lines, the 900 series robots appeared. Roomba 960 was released relatively recently, in 2016. Thus, it collected all advantages of the early models and multiplied them by some breakthroughs.

Though the appearance of the model seemed to stay unchanged, the case became significantly lower. With the new 3.6-inch height, this compact device could clean under the lower furniture and in more hard-to-reach places.

An attentive user will also notice a small camera on the top panel. This is the main part of the greatly improved visual navigation called vSLAM. Together with the well-known iAdapt 2.0 system (the second generation), they provide much more precise navigation and obstacle avoidance. Moreover, the 960 cleaner refuses adaptive movement and cleans in logical and efficient neat rows.

Intelligent route building and Dirt Detection guarantee the full floor coverage and minimize dirt missing even in high traffic zones.

Still, navigation is not limited by iAdapt 2.0 and vSLAM only. Roomba 960 became one of the first iRobot vacuums that applied Smart Mapping. This technology allows for scanning the dwelling and memorizing its every room as a map for further easy navigation. Users can also see this map in the app.
Roomba 960 Connectivity
If you’d like to prohibit cleaning in some area, use the Dual Mode Virtual Wall Barrier included in the kit.

The vac applies the same Dual Multi-Surface rollers with adjustable height, but they are both rubber this time. This design is completely tangle resistant, which makes the cleaner a great option for pet hair collection.

By the way, the suction of the 900 series robots delivers 5X the air power for improved pick-up performance. The maximum performance produces 900 Pa, so this model can be applied for low and medium carpets.

The robot provides excellent air treatment. It is equipped with a High-Efficiency filter that traps 99% of dust up to 10 microns in size and also deals with cat & dog allergens.

Smart connectivity includes the same WiFi supported app with a personalized schedule, Alexa and Google Assistant. However, the 900 and all further series got one more technology called Imprint Link. These vacuums can synchronize with iRobot Braava jet m6 robot mop. Thus, when dry cleaning is over, they automatically tell Braava jet m6 to start mopping.

Roomba 960 raised iRobot vacuums to the next level of quality and performance. Thanks to Smart Mapping, a twice bigger dustbin (600 ml vs old 300 ml bins), and Recharge & Resume, this model will guarantee cleanliness even in big houses.

The vacuum is filled with innovative features, but the newer i7 and S9 models’ release caused a significant price drop. That’s why the 960 supports a perfect balance between functionality and medium price. All these smart functions will cost you about $450.

We also highly recommend it to pet owners and allergic people. But, as usual, suction still doesn’t allow us to apply the vac on high carpets.

Pros

  • compact design
  • suitable for hard floors, low and medium carpets, and pet hair
  • 5X Power-Lifting suction (compared to the 600 series)
  • dual Multi-Surface Rubber rollers with height adjustment and anti-tangling
  • Dirt Detection
  • iAdapt 2.0 sensor navigation and vSLAM
  • Smart Mapping
  • no random and adaptive movement – cleans in rows
  • Dual Mode Virtual Wall Barrier included
  • High-Efficiency filter with anti-allergen treatment
  • big dustbin
  • Recharge & Resume
  • compatible with iRobot HOME app, Alexa, and Google Assistant for smartphone and voice control
  • Imprint Link for cooperation with Braava jet m6 robot mop
  • personalized cleaning schedule
  • reduced price

Cons

  • still insufficient suction for high carpets
  • still not quite durable battery (75 minutes)

Roomba E5

The E series Roomba E5 stands aside from other iRobot vacuums. One the one hand, it is very similar to the improved 900 series models and even outperforms them to some extent. But on the other hand, the lack of several functions doesn’t allow us to call it the best.

So, first of all, Roomba E5 is absolutely ideal for pet hair, hard floors, and carpets up to the medium-piled. It uses the same 5X motor and Power-Lifting suction. It’s an interesting fact, but real tests show that the E5 copes better with deep dirt than Roomba 960.

Perhaps, such an improved performance is caused not only by suction but also by brushes. Here, we see tangle-resistant Dual Multi-Surface Rubber rollers identical to the ones seen in the 960 vac. However, while the 960 rollers have the same blade design, the E5 rollers feature two different patterns for better scrubbing and capturing.

The cleaning is also reinforced by iRobot patented Dirt Detect sensors for quick determination and elimination of challenging spot messes. Apart from them, the E5 is also equipped with anti-collision and anti-drop sensors for primary iAdapt 1.0 navigation. Unfortunately, this is all navigation we have here, so the robot offers an old adaptive method with no route building, not to mention mapping.

However, filtration stays at the same level, providing nice anti-allergen treatment and thorough dust elimination. The model uses a High-Efficiency filter for particles as small as 10 microns.
Roomba E5 dust bin
The robot will suit even big apartments thanks to the durable battery for up to 90 minutes of work. Though the robot cannot automatically continue cleaning after recharging, it determines the low charge and comes to the dock by itself.

Run time and navigation might remind us of Roomba 675 model, and indeed, the E5 vac has some common features. However, WiFi connectivity is the characteristic that significantly differs them. Roomba E5 is compatible with all smartphones through the iRobot HOME app and with Alexa and Google voice assistants. Consequently, users get access to all pleasures of remote programming, customization, and control.

However, please mind that though it is also compatible with virtual walls, none is included in the kit.

Roomba E5 was included in the list of the best products in 2019. Indeed, it has all the right to be here. In a short word, Roomba E5 is a more affordable and simpler twin of the Roomba 960. The vacuum lacks Smart Mapping, Imprint Link, and Recharge & Resume. However, it offers the same low design, WiFi, anti-allergen filter, and even better rollers with higher suction. All these are available for $300.

Thus, Roomba E5 will be even a better option for pet hair and carpets than Roomba 960. The model will also suit people on a budget with small and medium dwellings (but not a multi-story one). We also recommend it to families with small children and those who want a personalized schedule, customization, and smart control for small money.

If speaking about contraindications, we would name people with big houses. iAdapt will not cope with too spacious and filled rooms. As well as the 5X suction will not cope with high carpets.

Pros

  • compact design
  • suitable for hard floors, low and medium carpets, and pet hair
  • 5X Power-Lifting suction
  • improved dual Multi-Surface Rubber rollers with height adjustment and anti-tangling
  • Dirt Detection
  • iAdapt 1.0 sensor navigation
  • adaptive movement
  • High-Efficiency filter with anti-allergen treatment
  • big dustbin
  • durable battery
  • compatible with iRobot HOME app, Alexa, and Google Assistant
  • personalized cleaning schedule
  • affordable price

Cons

  • still insufficient suction for high carpets
  • weak navigation and, consequently, not suitable for big dwellings
  • no Recharge & Resume

Roomba i7/i7+

Released in the second half of 2018, Roomba i7 made a splash in the household robotics world. The i7 became the first robot vacuum that could automatically empty itself without the slightest human participation.

Roomba i7+ was presented shortly after the i7. Let’s say it right from the start that these are two identical vacuums, the only difference between which is the kit. Roomba i7+ comes with the Auto Dirt Disposal base, while the i7 is compatible with it but needs it to be purchased separately.

So, this time, let us emit a detailed description of its 3-stage cleaning system with rollers and filtration. They are the same we’ve already seen in the Roomba 960. Roomba i7 and i7+ also support Imprint Link Technology for collaboration with iRobot Braava jet m6 mop. The manufacturer jokingly calls it «the dream team» function.

Surely, they cannot do without Dirt Detection and use excellent triple navigation based on iAdapt 3.0 (this time, we get even more improved third generation), vSLAM, and mapping. Numerous sensors cover the case and monitor obstacles and drops, while the camera gathers over 230400 data points per second.

However, when it comes to the mapping function, several interesting moments appear. Intelligent Mapping technology was improved since the time of the 960 vacuum. The i7/i7+ do not scan the dwelling over and over again during each cleaning but remember it. Besides, the i series robots can remember up to 10 unique floor plans, while the previous models could save only one map.
Roomba i7 Navigation
Such a top-level mapping opens even more control functions. Using the maps, we can set Clean Zones, which means we can choose separate rooms to be cleaned instead of the whole dwelling. Besides, there are Keep Out Zones that replaced physical virtual walls. You choose the areas where cleaning is not needed or desirable right on the map, and your robot will avoid them.

The manufacturer significantly increased suction. These two models have 10X the Power-Lifting Suction, which measures about 1700 Pa. Moreover, they use Carpet Boost technology. Thanks to it, the robots automatically determine when they come to the piled surface and increase suction to the maximum. All these features make them suitable even for high carpet cleaning.

However, Automatic Dirt Disposal stays the main advantage of the vacs. Users don’t have to worry about the bin size and empty it manually anymore. Cleaners control the filling and automatically come to the Base to throw the dirt. The Base bag is perfectly sealed and can contain debris from 30 cleanings.

For some reason, engineers thought that the Dirt Disposal base is enough and greatly reduced the bin capacity. It is a pity for those who will purchase Roomba i7 without the base and will face a small 400-450 ml container. Another significant drawback of the device is its extremely short run time. For such high suction and great performance, the manufacturer provided only 75 minutes of charge.

Roomba i7/i7+ now belong to the category of luxury robots. Both cost about $500-$650; also mind the Auto Dirt Disposal base for $250. Still, the price is just for such exceptionally precise navigation and innovations. Thus, the robots will suit all floor types, including high carpets. Neither pet hair nor large space will stop them.
Besides, these are the first devices we recommend for multi-story houses and people with severe dust allergies.

Pros

  • compact design
  • suitable for hard floors and all carpets, including high-piled ones
  • perfect for pet hair
  • 10X Power-Lifting suction
  • Carpet Boost
  • dual Multi-Surface Rubber rollers with height adjustment and anti-tangling
  • Dirt Detection
  • iAdapt 3.0 sensor navigation and vSLAM
  • Intelligent Smart Mapping
  • suitable for multi-story houses as can remember up to 10 floor plans
  • Clean Zones and Keep Out Zones
  • High-Efficiency filter with anti-allergen treatment
  • Auto Dirt Disposal function
  • Recharge & Resume
  • compatible with iRobot HOME app, Alexa, and Google Assistant
  • Imprint Link for cooperation with Braava jet m6 robot mop
  • personalized cleaning schedule

Cons

  • small dustbin
  • weak battery for only 75 minutes (which is criminally insufficient for such performance)
  • expensive

Roomba S9/S9+

Roomba S9/S9+ is the last but certainly not the least representative of the Roomba family. Moreover, here is the crown of iRobot engineers’ effort and the most advanced and the smartest robot cleaner among all series.

Brand repeated the previous devices’ experience and released the S9 and the S9+ in 2019 several months apart. Besides, the models are also twins except for the fact that the S9+ comes with the Dirt Disposal base, while the S9 users will have to purchase it separately if needed.

First of all, the manufacturer improved absolutely all basic features of the vac from the filling to the appearance. The latter is presented by a bit lower case (3.5 inches high) with a new D shape. Roomba has rejected its traditional round case for the sake of better edge cleaning. Moreover, the new PerfectEdge technology also contributes to this performance.

Secondly, though the robot uses the same dual Multi-Surface Auto-Adjustable rubber rollers, they became 30% longer for both tangle-free and quick cleaning after each pass. The robot offers the highest suction available in Roombas. Here is 40X suction power that reaches 2200 Pa in the Max and Carpet Boost modes.
Brushes-2 Roomba s9
Both modifications use the same High-Efficiency filter with 99% dust collection. But the system is improved with specially sealed Anti-Allergen case design and AllergenLock bags in the Dirt Disposal base. Vacuums eliminate main pet allergens, pollen, dust and prevent them from returning into the room. Roomba S9 and S9+ are certainly the best iRobot options for allergic people.

While the i series Roombas were suffering from a fast-dying battery, the newest S series comes with the most durable Lithium-Ion batteries for extreme 120 minutes of run time.

Engineers didn’t forget to equip the vacuums with all navigation technologies they have. Here we’ll see iAdapt 3.0 sensors, vSLAM with a fast-scanning camera, and Intelligent Multi-Floor Mapping. Clean Zones and Keep Out Zones are supported as well.

So, we can safely state that Roomba S9/S9+ are the most powerful, lasting, and innovative options among all iRobot vacs. These models collected all the best functions of previous devices (like Dirt Detection, Imprint Link, Mapping, anti-tangling brushes).

They are capable of cleaning all pollutions on all surfaces, including high carpets. Owners of multi-story houses won’t have to constantly monitor the robot, as excellent battery and precise navigation will do everything themselves. We also recommend them to allergic people, people with respiratory problems, small kids, and pets.

The only true problem to mind here is a too large price. Being the latest iRobot products, these Roombas belong to the luxury price niche and will cost you from $900 to $1100. Besides, you should remember that the S9 owners may have to pay extra $250 for the Dirt Disposal base. And with great probability, they will need the base since the dustbin stayed as small as in the i7/i7+ models.

Frequently Asked Questions

Where is Roomba manufactured?

Though iRobot Roomba is an American company, all its products are produced in China.

Frequently Asked Questions

How long Roomba robots last?

On average, Roombas last for 3-5 years. But please mind that the lifetime of your vacuum will greatly depend on your maintenance and proper use.

Do Roomba vacuums get stuck when climbing carpets?

iRobot takes care of its products’ possibility, so all presented models can overpass small elevations and obstacles up to 0.7 inches. They also easily climb carpets after the hard floor, but please mind that vacuums for low carpets can get stuck on the medium or high pile.

Are Roomba vacuum filters washable? How often should I change filters in my Roomba vacuum?

The manufacturer does not recommend either AeroVac or High-Efficiency filters to come into contact with moisture. To clean the filters, one should only tap them or brush them. Cleaning is needed once per week, while replacement should be performed every two months.

Can I purchase a Dual Mode Virtual Wall Barrier for my Roomba?

Yes, you can. All Roomba models are compatible with the Dual Mode Virtual Wall Barrier. Thus, you will be able to restrict cleaning in some areas (like under the desk with numerous wires or next to the pet bowls).

Conclusion

As you see, iRobot justly occupies one of the leading positions in the household robotics market. Indeed, your budget and requirements don’t matter – any customer will find his/her perfect Roomba option.

The newest Roomba i7/i7+ and S9/S9+ are the manufacturer’s best options for carpet cleaning and hair. Only they offer Carpet Boost function and the highest 1700-2200 Pa suction. You will hardly find something better for large multi-story dwellings. Besides, innovation hunters and extremely busy people will appreciate the Dirt Disposal function. However, we still wait for discounts since $600-$1100 prices are definitely not affordable for an average buyer.

Those who want to get something close to the previous models but for a more democratic price should pay their attention to Roomba E5 and 960. They are the best golden mean products with nice carpet and hair cleaning. The final choice between them will only depend on your necessity for precise navigation. The owners of small apartments will be quite satisfied with simpler and cheaper Roomba E5. Roomba 960 is slightly more expensive, but the difference is not that dramatic, and you’ll get Smart Mapping, vSLAM, and Recharge & Resume.

Speaking about Roomba 675 model, we would call it the best extra budget choice for unpretentious customers. This vacuum under $300 offers quite efficient basic cleaning features with only the most necessary functions. Still, it supports smart connectivity and WiFi control. The only moment to mind is that it suits small apartments under 1500 ft2/150 m2.

Roomba 614 is the most affordable vacuum by iRobot. However, the lack of WiFi support (that became rather a necessity than a caprice) makes it a bit outdated option in our opinion.
