Here, find the best Roombas for all your vacuuming needs.
Best Overall: iRobot Roomba s9
Battery Life: 120 minutes | Cleaning Path Width: 10.7 inches | Mapping: Yes | Filter Type: Replaceable | Brush Type: Rotating brush bar and side brushes | Smart Capabilities: Yes
Extremely powerful suction
If you're looking for a vacuum with all of Roomba's best features (and then some), go for the s9. It's about as technologically advanced as Roombas get, featuring Wi-Fi and app integration, learned mapping and navigation, and compatibility with both Alexa and Google Assistant. But, where this model shines is in its ability to clean—and we mean really clean—the entirety of your home.
With 40 times the suction power of a standard Roomba, the s9 simultaneously lifts away small and large debris from all floor surfaces and extracts embedded crumbs from carpets. Its extra-wide, multi-surface rubber brushes prevent hair from getting tangled and, instead, shedding, dander, and other pet-related allergens are whisked away and trapped by the high-efficiency filter. Even corners and baseboards will get a deep cleaning from the s9, thanks to its specially designed corner brush.
Granted, the s9 is on the pricier side, but you're paying for an elite level of clean that few vacuums, even other Roombas, can replicate.
Best Mid-Range: iRobot Roomba e5
Battery Life: 90 minutes | Cleaning Path Width: 13.39 inches | Mapping: No | Filter Type: Replaceable | Brush Type: Rubber brushes | Smart Capabilities: Yes
Mid-range price point
Cleans up small and large debris
Random cleaning path
No virtual wall barriers
If you’re looking for a value-packed Roomba, the e5 model is worth considering. Unlike some of the other members of the roaming Roomba family, the e5 isn’t the most feature-driven, but it includes the latest essential features.
The Roomba e5 features built-in Wi-Fi so you can monitor the mighty vac’s cleaning activity and issue voice commands via Amazon Alexa and Google Assistant. It runs for about 90 minutes before it has the smarts to dock itself for a recharge.
Like all new generation Roomba robots, the e5 features multi-surface rubber brushes that flex to maintain contact with floors. However, due to the mid-range price tag, this Roomba doesn’t come with any virtual wall barriers or the latest in smart mapping features. Even still, it offers major upgrades in terms of suction, battery life, and other smart features (like automatic recharging) over budget Roombas on the market.
Best Splurge: iRobot Roomba s9+ 9550 Wi-Fi Connected Robot Vacuum
Battery Life: 120 minutes | Cleaning Path Width: 9.5 inches | Mapping: Yes | Filter Type: Replaceable | Brush Type: Rubber side and corner brushes | Smart Capabilities: Yes
Extremely effective at removing pet hair
Cleans corners easily
Louder than expected
For the ultimate Roomba, look to the new sleek and smart Roomba s9+. This top of the line Roomba is a splurge-worthy option that includes all the latest features of robotic vacuums, for a premium cleaning experience—and a premium price.
The Roomba s9 series available with or without a dirt disposal base, but to really get the most of Roomba’s smart vacuum, opt for the s9+, which can automatically empty its contents into a vacuum bag housed within the base. The bag can hold the dirt and debris from up to 30 cleaning sessions, and the unit will alert you within the app when it’s time to change the bag. This is Roomba’s most independent vacuum yet, meaning you don’t have to frequently empty the small, onboard dust bin.
Of course automatic dirt disposal isn’t the only thing that makes the s9+ the premier Roomba to buy. This model includes Imprint Smart Mapping, which enables it to learn your home’s floor plan for efficient vacuuming or on-demand clean-up of specific rooms. You can enable this feature by controlling Roomba with Amazon Alexa or Google Home, with commands like, “Roomba, clean my bedroom.” The smart mapping feature of this Roomba also enables it to learn multiple levels of your home, making it easy to move the robot upstairs or downstairs without disrupting its memory of the other levels. This isn’t true of all Roomba models, which also qualifies the s9+ as a top robot vacuum for multi-level or large houses.
This Roomba is noisier than some other models, but it is attributed to the increased suction power of the s9+. In fact, the s9 has 40 times the suction of Roomba’s early 600 series robot vacuums. This translates into a deeper clean on all types of surfaces, including hard flooring and carpeted surfaces.
"After the s9+ cleans your house a few times, it creates a smart map of the cleaning area you can view in your iRobot app. With the map, you can mark off the areas you want the robot to avoid for future cleanings. I tested it to see if it works, and it does—really well. The robot uses its memory to clean the mapped areas while avoiding the off-limits zones."—Lindsay Boyers, Product Tester
Best for Carpet: iRobot Roomba 614 Robot Vacuum
Battery Life: 90 minutes | Cleaning Path Width: Not listed | Mapping: Yes | Filter Type: Replaceable | Brush Type: Main and side brushes | Smart Capabilities: No
Affordable for a Roomba
Three-stage cleaning system
Limited dust bin capacity
Robotic vacuums sometimes struggle to thoroughly clean carpets, due to their soft surface and raised height. But, thanks to its clever design and innovative technology, this Roomba is more than capable when it comes to cleaning the carpets throughout your home for up to 90 minutes at a time.
Its three-stage cleaning system, loosens, lifts, and sucks away debris of all sizes (including pet hair), thanks to its two main cleaning brushes. Its dirt detection sensors ensure that particularly dirty, high-traffic areas don't go overlooked, while the Edge-Sweeping Brush tackles dust and crumbs along baseboards and in corners. And the Roomba 614's cleaning head automatically adjusts when it moves between different floor surfaces.
Although it's one of the more affordable Roombas on the market, this model doesn't skimp on power, consistent suction, or efficient cleaning.
Best for Smart Homes: iRobot Roomba i7
Battery Life: 75 minutes | Cleaning Path Width: 7 inches | Mapping: Yes | Filter Type: Replaceable | Brush Type: Rubber main and side brushes | Smart Capabilities: Yes
Compatible with Amazon Alexa and Google Assistant
Easily navigates rooms and obstacles
Steeper price point
Cannot run overnight
If you want the best Roomba for smart homes, check out the full-featured and high-tech Roomba i7. This smart robot vacuum doesn't cost as much or run as long as Roomba’s top model, but packs in all the smart home integrations you’re looking for.
The most significant features of the Roomba i7 is its navigational abilities and mapping technology. With iAdapt 3.0 Navigation, this Roomba vac is able to map its surroundings and retain the memory of your floor plan for future cleanings. Added visual localization enables Roomba to capture ‘landmarks’ it uses as a reference point for where it’s already cleaned. Imprint Smart Mapping and Link Technology give you advanced control over where and when the Roomba smart vacuum cleans. Schedule specific rooms via the Roomba app or issue voice commands with compatible smart home systems like Amazon Alexa and Google Assistant.
We also love that this Roomba for smart homes takes home automation to the next level by using Imprint Link technology to automatically vacuum and mop your floors if you have a compatible Braava Jet machine.
This Roomba is also smart enough to empty its own dustbin if you spring for the self-cleaning base. It’s available as an add-on, so you can opt for the smart vacuum only or purchase the base separately at any time.
Best Budget: iRobot Roomba 675
Battery Life: 90 minutes | Cleaning Path Width: 7 inches | Mapping: No | Filter Type: Replaceable | Brush Type: Rolling bristles and edge brush | Smart Capabilities: Yes
Affordable for a Roomba
Effectively cleans edges and corners
Hair tends to tangle in the brushroll
Random cleaning path
The best time to buy a vacuum is generally around the holidays or spring when prices drop low. If you're looking to capture savings throughout the year the Roomba 675 comes at a reasonable price year-round. This basic robot vac includes familiar Roomba features but skips the bells and whistles for a lower price tag.
The Roomba 675 comes equipped with the most essential Roomba upgrades of the last several years, like a longer 90-minute runtime with a lithium-ion battery, Wi-Fi connectivity, and automatic recharging. These features fix some of the frustrations expressed by earlier owners of budget Roomba vacuums. The Roomba is able to accomplish more with the 90-minute cleaning cycle and you can monitor its cleaning progress or schedule cleaning sessions within the app, thanks to its built-in Wi-Fi. And instead of finding your Roomba drained and out of battery juice in the middle of a room, the 675 can dock itself to recharge.
Unlike some of the latest models of Roomba vacuums, the Roomba 675 uses a pair of bristle brush rollers to conquer dirt and debris. So, while the bristles do an excellent job of gathering hair, it occasionally becomes caught around the brush itself and requires extraction. Just make sure to empty it of hair regularly and it will repay you with consistent trouble-free operation.
The bottom line is that this budget Roomba will require more hands-on interaction for tasks like emptying the somewhat small dust bin and removing hair that becomes caught. However, its an affordable option for the convenience of a robotic vacuum.
Best for Allergies: iRobot Roomba i6+
Battery Life: 75 minutes | Cleaning Path Width: Not listed | Mapping: Yes | Filter Type: Replaceable | Brush Type: Rubber main and corner brushes | Smart Capabilities: Yes
AllergenLock dust bag
Automatically adjustable cleaning head
Anyone who deals with allergies knows that even trace amounts of pollen, mold, or dander can make a room feel downright inhospitable. Luckily, the Roomba i6+ can access nooks and crannies, where irritating allergens can easily accumulate, that a regular vacuum might not be able to. And, any dust bunnies it comes across are rapidly sucked up and trapped inside its AllergenLock bag. The i6+ will automatically empty itself at its Clean Base for up to 60 days before needing to be emptied and replaced by hand (which won't incur any secondhand messes or contact with allergens, as the bag seals completely shut).
The i6+'s rubber brushes, automatically adjusting cleaning head, 75-minute runtime, and power-lifting suction make for a formidable combination against messes of all sizes. Where the brushes and cleaning head allow it to transition between hard and carpeted floors with ease, the latter steadily extracts debris regardless of the surface.
Best for Hardwood Floors: iRobot Roomba i3+
Battery Life: 75 minutes | Cleaning Path Width: 7 inches | Mapping: Yes | Filter Type: Replaceable | Brush Type: Rubber main and corner brushes | Smart Capabilities: Yes
AllergenLock dust bag
Smart cleaning recommendations
Loud cleaning base
No virtual wall barriers
Whether you set this Roomba loose in rooms with carpet, hardwood, or tile, you can trust that it will clean up any and all messes it comes by. This is thanks to its dirt detection sensors, power-lifting suction, and dual multi-surface rubber brushes working together to ensure a consistent clean, regardless of the flooring. It cleans in straight rows, with adaptive technology that learns the layout of your home and offers cleaning recommendations depending on the season (say, during shedding season or high pollen count periods). Plus, this model is as efficient as it is smart: Even large debris and pet hair get handily swept away, rather than scattered across the room.
When the i3+'s job is done (or when it runs out of juice around the 75 minute mark), it returns to its base and empties itself into the base's AllergenLock bag, which can hold up to 60 days' worth of dirt and is designed to trap and seal away 99 percent of common allergens.
What to Look for in a Roomba
The size and square footage of your home should play a key role in how you choose which Roomba is right for you. A smaller house or apartment won't need a Roomba with the longest battery life or the largest dust bin available, but a larger home might. In addition to how long a model will hold its charge and how much dirt it can hold onboard, also take into account whether it has a self-emptying feature, which may need to be purchased separately.
Most Roombas can adjust to changes in floor surface automatically, but you'll want one with particularly powerful suction (and perhaps a higher-capacity dust bin) if you're hoping to clean carpeted rooms with it, as higher pile surfaces will likely have more dirt and dust tracked into them. On the other hand, if your home mainly has hard floors, look for a model with rubber brushes, which will prevent debris scatter and catch dirt on tile and hardwood.
Newer and more advanced Roombas come with such bells and whistles as home mapping, adaptive technology, and app and smart home device integrations. These features will provide you with a better idea of how your Roomba cleans your home as well as a more sophisticated, empowered user experience. If all you want is a device that will clean your floors while you tackle other tasks, these features may be less of a priority.
How do I empty a Roomba?
You can remove your Roomba's dust bin by pressing the bin release button or tab. This will allow you to lift out the bin and empty it into the trash before sliding it back into place on the Roomba's main body. If your Roomba is on a dirt disposal base, simply press the "HOME" button to empty its bin.
How do I maintain a Roomba's battery?
To ensure your Roomba's battery lasts as long as possible, keep it plugged into its charger or charging base when it isn't actively vacuuming and don't let it sit out, away from its charger, after it finishes cleaning. Make sure to clean the charging sensors once a month, empty its dust bin before it reaches maximum capacity, and address clogs as soon as you notice them.
How do I reset a Roomba?
Certain technological issues, like connectivity problems, may require you to reset or reboot your Roomba. For most models, you simply press and hold the "CLEAN" button for 10 to 20 seconds and wait up to 2 minutes for the reboot to finish. Some models will require you to hold down both the "HOME" and "SPOT CLEAN" buttons for 10 seconds in order to reboot.
