Robotic vacuums are increasingly useful regardless of if you live in a house or an apartment. From the inexpensive Ecovacs and Eufy robovacs, to the the more costly and feature-packed Dyson 360 and iRobot Roomba's, you'll find robovacs suitable for any budget. The main things you'll want to look for are robots with strong suction power, good navigation for getting around your home and obstacles, and extra features like automatic cleaning and Amazon Alexa voice commands. We've researched and reviewed robovacs across a number of brands to find the best ones.
Intelligent navigation and mapping
Automatic cleaning and emptying
On the costly side
The iRobot Roomba i7+ boasts a respectable 1.5-hour run-time and powerful suction that promises to pick up 99% of dust, pollen, and grime. Its cleaning system features two multi-surface rubber bristles and a robust air vacuum with 10x more air power than the Roomba 600.
The Roomba i7+ also includes a host of intelligent features, allowing it to navigate and prioritize which rooms need to be cleaned. Its patented iAdapt 3.0 Navigation with vSLAM technology creates a digital map that allows the Roomba to operate without bumping into walls. It is also equipped with Google Assistant and Alexa, so you can enjoy the hands-free controls (although the robot is so self-sufficient, you might not need it). When finished cleaning, the Roomba retreats to its “home base,” where it automatically empties into a large receptacle that holds up to 30 loads — this means that even if your Roomba vacuums every day, you only need to empty the bin once a month. This compact robot weighs less than eight pounds and measures 13.34 x 3.63 inches.
Unique D-shape design allows for corner cleaning
Good mapping technology and navigation
The Neato Botvac is one of the most innovative robot vacuum cleaners on the market. The unique D-shaped design gives it a different appearance from some of the other top sellers, but it was made that way for a good reason - the shape allows the Botvac to back into edges and corners. Using Neato’s CornerClever technology, the Botvac can suction up all those crumbs close to your wall and hide in every nook and cranny.
The long-lasting, rechargeable lithium-ion battery means the Botvac can clean more area on a single charge, and its LaserSmart mapping and navigation technology provides real-time object detection and even lets your Botvac work in the dark. This also allows the Botvac to scan the room and create a cleaning plan instead of aimlessly spinning around. Do you have some off-limits areas?
Create virtual “No-Go” lines so your robot learns what areas to leave alone. Plus, start or schedule cleanings using the Neato app on your smartphone, Apple Watch, Amazon Alexa, Google Home or IFTTT with the Botvac’s built-in 5GHz Wi-Fi.
Has auto clean mode
Supports Amazon Alexa commands
Navigation could be better
Can't handle big spaces
Users love the budget-friendly EcoVacs Deebot. This little cleaning robot packs a lot of power with five cleaning modes, including a smart motion guided auto-clean mode, single room and spot mode for targeted cleanup, edge mode and max mode for extra-dirty areas. The efficient vacuum suction power, the helical deep-reach main brush, and wide-reach side brushes all work together to thoroughly clean your home.
Try using the EcoVacs app to create custom settings, schedule run times and even monitor cleaning sessions remotely. You can also check the cleaning status and receive error alerts directly to your smartphone. If you have Amazon Alexa, try giving commands to your very own robot vacuum with just your voice and enjoy the feeling of living in the future you’ve always wished for at a fraction of the cost of some of the other best-selling competitors. The EcoVacs Deebot comes with a one-year warranty and a 100 percent money-back guarantee, too.
"The Deebot N79S is the ideal robovac for an apartment dweller that wants some maintenance cleaning done without spending too much." — Ajay Kumar, Tech Editor
D-shape for better edge and corner cleaning
Needs a Braava Jet for ideal cleaning
The Roomba S9+ believes having a clean home shouldn’t require you to give up your free time — as long as you’re willing to pay for it. iRobot’s latest comes with a price tag about a grand steeper than basic options on the market. But, as the company is so keen to demonstrate, that is simply the cost of making your life a little easier.
The S9+ is self-cleaning, thanks to a CleanBase docking port that charges its battery and empties its dustbin. The robot’s body has been modified from round to a D-shape so it’s better able to tackle corners and edges, an upgrade enhanced by PerfectEdge technology, which ensures the Roomba will run closely around walls to ensure no spots are missed. The Roomba S9+ is meant to be paired with iRobot’s new Braava Jet m6, a mopping robot — the two communicate through the iRobot mobile app so the m6 will commence cleaning once the S9+ has finished.
Capable of mopping floors
Good mapping and navigation
Larger water tank than previous models
Supports Alexa and Google Assistant
Works best when paired with Rooba S9+
Taking the "work" out of housework, the Braava Jet m6 joins iRobot’s robot cleaning family to clean nearly any floor in your home. Taking pointers from Roombas, the m6 has intelligent floor mapping skills so that it can learn the layout of your house and navigate through multiple rooms, and, when it runs out of juice, knows to navigate back to its charging dock (the first in the Braava line to have one) to charge before completing its task.
The m6 also has a larger water tank than previous models, which can be filled with water or cleaning solution. It is able to clean around and under furniture and can detect the type of cleaning necessary based on whether you attached a wet mop or a dry sweep pad. Its schedule can be customized through the iRobot app, and it is compatible with Alexa and Google Assistant.
Good at handling pet hair
Has 80 sensors on all sides
Supports number of accessories and filters
No Wi-Fi or app support
When it comes to effectively picking up pet hair, you need a robotic vacuum that offers the absolute best suction and sterilization. Enter the bObsweep PetHair Plus: one of the first robotic vacuums on the market to specifically target pet owners and assist them in maintaining a hair-free home.
Pick up the bObsweep and you can say goodbye to paw prints and pet hair; the robotic vacuum is in a league of its own as it sweeps, mops, HEPA filtrates, and UV sterilizes all at the same time. With 80 responsive sensors on the front, sides, and bottom, the bObsweep Pet guarantees it can handle pet hair and any other debris in the vacuum’s path.
Owners of large dogs will appreciate the one-liter dustbin which is among the most sizeable in the industry and is easily removed for washing, disinfecting, and reinserting. Even pet hair that finds its way into baseboards will be no match for the bObsweep as heavy-duty side brushes can safely enter baseboards and rid your home of rogue pet hair.
Can fit under most furniture
Cleans hardwood floors well
Amazon Alexa and Wi-Fi support
Runtime is on the shorter side
Shark is a name that’s synonymous with vacuuming, so its entry into the robotic vacuum space comes as no surprise. The brand's ION model presents an 11-inch brush with self-cleaning bristles as well as two additional rotating brushes on each side that aim to capture any stray dust or debris from corners and edges. With a 380-mL dustbin, the vacuum is large enough to handle medium-sized homes, and its low profile design — it measures under three inches in height —allows it to safely pass underneath most furniture.
Hardwood floors are one of the ION's specialties; helix-pattern high-tensile bristles thoroughly clean while detangling technology ensures that any long string or hairs won’t interrupt the vacuum’s function. As it navigates around up to 60 minutes on a single charge, the Shark’s Smart Sensor navigation works in tandem with internal proximity sensors to avoid obstacles ensuring it won’t scratch your couch or coffee table. Wi-Fi capability allows the Shark ION to sync to Amazon's Alexa platform so you can schedule cleaning directly from your smartphone or via voice control with your smart home hub.
Three-point cleaning system
Good obstacle and drop avoidance
Not best at handling corners
The Eufy RoboVac 11+ is one smart little robot. It uses BoostIQ Technology that detects extra-messy areas and automatically increases suction power to get the job done. Eufy has improved on previous models of this robot with a new front bumper that gives RoboVac a sleeker, more streamlined appearance that also enables it to slip around and under your furniture.
Each RoboVac comes equipped with a three-point cleaning system that includes a wide rolling brush, two side brushes, and powerful suction. A scratch-resistant tempered glass cover protects your housekeeping robot and an infrared sensor helps the RoboVac avoid obstacles. Drop-sensing tech means the RoboVac won’t be taking any plunges down the staircase, and it is clever enough to recharge automatically. Plus, it comes with a worry-free twelve-month warranty – now that’s what we call smart.
Strong suction power
Solid navigation for optimal cleaning
Automatic recharging and support for Samsung Smart Home
A bit on the bulky side
The Samsung POWERbot lives up to its name with 40 times the suction power of the previous model. With an onboard digital camera and nine individual smart sensors, the POWERbot is able to create an optimal cleaning path and can dodge furniture or even unexpected objects on the floor like your discarded work shoes or your kid’s backpack. The POWERbot’s Edge Clean Master technology has an extendable shutter that cleans right up against edges and corners, and its Self-Clean Brush helps prevent tangles from hair or strings.
When the battery runs low, you don’t have to worry – the POWERbot automatically moves to the docking station to recharge itself, then goes back to its last location to resume cleaning after fully recharging. Thanks to built-in Wi-Fi connectivity, control your robot vacuum with your smartphone or tablet via Samsung’s Smart Home, the Smart Things app or Samsung Connect. Plus, you can check the POWERbot’s coverage map to see where your robot has already cleaned before letting it loose in a new part of the house. You can even use voice controls with Amazon Alexa or Google Assistant.
Great at handling dust particles
Good navigation/vision system
Dyson has made a name for itself as a company that is serious about creating quality vacuum cleaners. With the Dyson 360 Eye, it has a new robot vacuum cleaner to boast about that features twice the suction power of any other robot vacuum cleaner on the market. The secret to its cleaning power? The Dyson 360 Eye features a small, light digital V2 motor, as well as Dyson’s famous Radial Root cyclone technology that separates larger dirt particles from dust to ensure that once the debris is picked up it stays in the bin until you empty it.
A full-width brush bar gives the eye a wide cleaning range, so it can provide edge-to-edge cleaning across hard floors and carpets with durable nylon and carbon fiber bristles. The Eye is named for its 360-degree vision system that allows it to view your entire room, so it can create a map of your home for smarter navigation and systematic cleaning. Plus, with the Dyson Link app, available on iOS or Android, you can start and stop, schedule or receive reports about your robot vacuum no matter where you are.
If you're looking to keep your home or apartment clean on a weekly basis without having to spend too much time, the Roomba i7+ from iRobot is one of the best robovacs you can get. It boasts great navigation and battery time, strong suction power, and even the ability to empty its own dustbin. Another good alternative is the Neato Botvac D7. It has a unique D-shape making it ideal for cleaning corners and edges, a contrast to most other robovacs.

Cleaning can be a hassle, but robot vacuums make the household chore of keeping floors clean almost painless. The recommendations on our list cater to a range of living spaces and budgets, and those are two important places to start when you’re shopping for this kind of gadget.Some pricier models are better for certain surfaces and types of messes, and intelligent enough to adjust cleaning settings based on the type of flooring. But even a few budget-minded models offer Wi-Fi and smart home connectivity. And if you like the idea of having a fully powered machine at all times, there are robot vacuums clever enough to return to a docking station to recharge and resume.
If you’ve never owned a robot vacuum, it can be difficult to anticipate what aspects will matter most for your real-life cleaning needs. Use this guide to help you uncover the robot vacuum features that will be most useful and necessary in your home.
There’s not a huge amount of variety when it comes to the design and general build of a robot vacuum. All of them feature some combination of brushes, wheels, and a battery-powered motor that provides suction power. The most common body shape is completely round, but you’ll also find D-shaped robot vacuums that sport one flat side. These models often feature a wider main brush on the flat side and can meet edges much more closely than round models. That means more precise cleaning along walls and in corners that round robots can’t quite reach.
Another thing to consider is how much a robot vacuum weighs. Typically they range between five to eight pounds or so. While you won’t be picking them up or wielding them the way you would a handheld, upright vacuum, if you do have to move one up and down stairs or redirect it, a model that’s closer to ten pounds could be cumbersome. Heavier models are often bulkier and taller as well. Even as little as five inches high could be too much to fit under some lower furniture or under low cabinets and shelves. Shorter and slimmer models will be the safer bet if you have a lot of furniture and built-ins without much clearance.
How do you gauge just how powerful a robot vacuum is? There are a lot of claims that manufacturers throw out. Dyson says that one of its models boasts more suction power than any other autonomous vacuum. While it’s hard to know what that means exactly, you can find some clues based on the information brands supply about the motor technology and suction modes. Try to find the speed of the motor in RPM or revolutions per minute. The higher the RPM the more powerful the motor is, which means greater capacity for sucking up everything in its path. The Dyson brand is known for its digital motor that can reach over 100,000 RPM. According to the EPA, most motors typically fall below or at 30,000 RPM.
If you can’t track down this information, look for hints about power settings. Some models have advanced suction or so called max-suction modes that maximize a motor’s power and reach further into crevices and hard-to-reach areas. Other brands like Eufy measure this capability in pascals (Pa), where the higher the Pa the greater the suction power a model offers.
Also consider the kind of flooring you’re working with. Carpets will need a machine with more gusto than hardwood or tiles. If you have little to no carpet, you won’t need as much suction power.
Robot vacuums aren’t necessarily as capable at deep-cleaning as other vacuums that require manual operation. If you have specific cleaning needs—maybe you have young children and deal with frequent food spills or long-haired pets that shed—look for products that shine brightest in those areas.
If you’re interested in not having to prompt your robot vacuum to get to work, consider models that are smart enough to clean automatically. Options that are Wi-Fi-connected are programmable from the convenience of a mobile app—so you can schedule routine sweeps through your kitchen or living room at designated times during the day. Some models also come with specific cleaning modes like spot or targeted zone cleaning so that you can make sure the highest-traffic or mess-prone areas are spotless.
Robot vacuums that get to work regardless of whether you’re home are also often clever enough to head back to their charging docks when finished or when they need more power, or even self-empty their dustbins when full.
Not all models are as adaptable to different flooring. Some can only handle low-pile rugs in addition to tile and hardwood, but can’t manage thick carpet or dark-colored floors. If you have a mix of carpeted and uncarpeted surfaces, you’ll want to find models that don’t get tripped up by the transition. Models that can detect surface changes use adaptive wheels to help move them onto carpet from non-carpeted floors. They’ll also be able to automatically sense what kind of material they’re cleaning and match it with suction power—or you’ll have the ability to set the suction mode based on the floor type.
If you don’t have much carpet in our house or apartment, hardwood-to-carpet versatility isn’t as important as brushes that can extend into corners and a motor that offers enough suction to pick up crumbs and dust particles.
A mopping function could be an added bonus if you have a carpet-free home. While there aren’t many two-in-one robot vacuums that offer equally strong mopping functionality, the iRobot line manufacturers a mopping robot that can be paired with a vacuuming model from one of the other product series. Or some models from brands such as bObsweep and Roborock come with mopping attachments.
Not all models do that well with pet hair. You’ll have the most luck browsing options that are specifically built for pets and carpet. These robot vacuums won’t get caught up by pet hair and will be effective at removing it from carpets and baseboards, and will have a large enough bin to operate without having to be emptied all the time. And since there are many allergens in the air from pet dander, pet-friendly robot vacuums have HEPA filters or some sort of advanced filtration system to reduce irritants in the air. The Samsung POWERbot R7260even has a self-cleaning brush mode that prevents brush tangling from pet (or human) hair.
A robot vacuum that always falls down the stairs, gets tangled in cords, or bumps into furniture is a less-than-ideal cleaning aid. All models are prone to some sort of hiccups from time to time. A mess of cables or a free-standing cup of water can be major blocks and catastrophic to these machines. But the most effective robot vacuums have advanced systems, sensors specifically, to prevent these interruptions from derailing them.
These sensors serve as the machine’s eyes and determine how they function when presented with various circumstances. The main sensors account for walls, obstacles, and stairs. Wall sensors help robot vacuums recognize walls and then get to work with a thorough sweep of baseboards. Obstacle sensors are responsible for sensing and maneuvering around objects they come into contact with—anything from a coffee table to shoes—rather than repeatedly bumping up against them. Cliff sensors prevent a tumble down stairs by detecting the distance from the bottom of the device to the floor. If the system spots an increase in this distance, then it will let the robot know a drop is ahead, and to avoid it.
While those are the main sensors all robot vacuums usually share, not all offer wheel or optical sensors that use lasers to orient themselves. These sensors give the machine a sense of location by determining how many turns it has completed and the overall distance traveled. This kind of sensor is critical to a robot vacuum’s ability to navigate around your home without any intervention. The most advanced models on the market come with mapping technology that helps the device learn the layout of your home, register landmarks, remember which areas need the most attention, and also know which areas to avoid completely.
You can count on even the most inexpensive models to have a certain level of awareness of your home’s surroundings and ability to navigate around them. But if you have large rooms, special trouble areas, or targeted cleaning concerns, consider models that offer more advanced sensors and navigation software that receives regular updates.
Not every robot vacuum is uber-sophisticated when it comes to connectivity options. Many models that aren’t as smart do come with a remote that you can use to program a cleaning time. But if you’d like the freedom to speak a command like “Clean the kitchen,” you’ll want to look for models that are compatible with voice assistants. Most models that are smart-home-capable are at least compatible with Google Assistant and Amazon Alexa, but some offer access through Siri or Samsung’s Bixby.
These more intelligent models also come with built-in Wi-Fi compatibility with 2.4Ghz or both 2.4Ghz and 5Ghz frequencies and work with a dedicated app that allows you to set cleaning schedules, make more precise mapping tweaks, and ensure your machine is up to date with the latest software tweaks. The smartest robot vacuums can also work diligently while you’re not at home, thanks to the virtual access the software and mobile app provide.
According to the American Speech Language Hearing Association, anything above 85 decibels can be damaging to hearing. Luckily, robot vacuums are generally pretty quiet and fall within a safe range of 60 dB to 68 dB. If you’re not a fan of loud machine noises, even a slightly lower decibel rating could make a difference in the user experience. Or models with a quiet mode could help you keep your house clean even when loved ones are asleep.
Robot vacuum battery lives typically range from 60 to 120 minutes, though some can perform for up to 3 hours at a time. If you live in a small city apartment, it’s unlikely that you’ll need all of that time to cover your whole dwelling. But if you have a large home with large rooms and more than one floor, you’ll probably want to choose the model with the longest battery capacity. Consider charging times as well. Longer-lasting models tend to have equally lengthy charging times, but they’re also often capable of quick-charging to an adequate degree so that they can resume their work.
Robot vacuums can be very expensive. Some systems from the iRobot or Dyson brands cost over $1,000 and are aimed at buyers who want a comprehensive and rugged cleaning machine—and possibly forego other sweeping and mopping tools. Budget models that offer Wi-Fi connectivity and a decent feature list can cost $200-$300, and mid- to upper-range models are still pretty pricey, at between $500 to $800, but offer many of the same extras as the most expensive models.
As with any other larger home appliance, price isn’t always the most definitive marker of the value of a robot vacuum. If your home is small and you don’t have pets, a more modestly priced model can still offer smartphone connectivity ease and efficient cleaning. Chances are, if you live in a larger, multi-story home, a robot vacuum may not be the only machine you’ll use. While it’s great for daily cleaning and upkeep, deeper cleaning could require upright machines too. That’s another consideration for your wallet.
Many of the most well-known vacuum brands (Shark, Dyson, Bissell) also offer autonomous models, but there are several manufacturers that work specifically in the robot vacuum space. It can be tricky to decide between seasoned vacuum brands and those that specialize in robots that clean. There’s definite overlap, but some manufacturers listed here offer decidedly more or more specific features for certain buyers.
This brand is probably the best-known producer of robot vacuums. Their Roomba models are divided into several different collections that offer a range of bells and whistles. The 600 series is the most affordable, starting at around $250, and offers basic multi-surface cleaning without smartphone connectivity. You can step up $100 to the e Series, which are geared toward pet owners, whereas the i Series and s Series models, ranging from $600-$900, are more sophisticated in looks and extras. The higher-end Roomba models come with the latest advanced sensor and mapping technology for more accurate performance and other conveniences like self-emptying bins. Almost all Roomba models can be paired with accessories that increase performance, whether that’s a virtual wall barrier that keeps the machine out of rooms you don’t want it to clean or tag-teaming with the Braava robot mop.
Eufy manufacturers many home and smart home-related products, including robot vacuums. Their models tend to be some of the more affordable on the market, within the $220-$250 range. Some, but not all, offer the ease of Wi-Fi and app control. But those that don’t have this convenience come with a remote control for programming cleaning sessions. The fanciest model, the RoboVac L70 Hybrid, costs only about $500 and sweeps, mops, and lasts for as long as 2.5 hours. Most Eufy models are relatively slim and short enough to fit under cabinets and furniture. You’ll also have no trouble finding the suction power value in Pa (pascals), which is listed for every model. But charge times can be lengthy with these machines—as long as 6 hours on some of the most basic models.
This brand is a dedicated smart home robot vacuum developer (though they also make a couple of window cleaning robots as well). The Deebot series of vacuums starts with versatile and budget-friendly models that retail for under $200, are Alexa-compatible, and boast decent run times of 120 minutes or longer. On less expensive models, there are fewer flourishes like floating brushes, self-emptying ability, and charge times hover around 4 hours. But more powerful and pricer models (within the $600 range) offer multiple cleaning modes along with dual mopping/sweeping ability, run times of 3 hours, and will even check in with you to let you know—with a voice report—what they’ve been up to.
This robot vacuum manufacturer offers just three models presently, and they range in price from about $400 to $650. All are controllable by voice and mobile app and can mop floors too, but the more advanced two models have a longer run time of 150 minutes, more suction power (2000 Pa vs. 1800 Pa), modes for zone-cleaning, and advanced mapping technology that supposedly measures your home and all obstacles within 0.8 inches of accuracy. Roborock also provides helpful information for each model that other manufacturers don’t list so plainly—such as decibel level, dustbin volume, and the best fit based on the size of your home.
Even though robot vacuums are small and self-contained, you may end up having or wanting to replace some of those components. While bags aren’t a concern, think about filter replacements or cleaning needs. Samsung machines come with a washable filter, which eliminates the need to replace this item and iRobot offers a washable dustbin and a dirt-disposal station that doesn’t require you to empty the dustbin at all.
Some companies sell individual parts like rolling and side brushes that can be swapped out to enhance performance or replace a faulty part. Eufy and Roomba also sell battery replacements to keep certain models at peak charging performance and mapping accessories (boundary strips, virtual wall barriers) to help your robot better understand boundaries and floorplans.
A robot vacuum can simplify the way you clean your studio apartment or multi-story home. The price tag doesn’t always signify quality, and should be weighed against the size of your living space and whether you need specialized cleaning to manage pet hair and different surfaces (hardwood, carpet, tile, etc). It’s also worth considering the kind of control you’d like to have over scheduling cleaning sessions from a remote or smartphone app, and just how much you can coach the machine to get the job done.
While a robot vacuum could be a supplemental tool in your arsenal for keeping a tidy home, and not your sole option. We hope that considering these traits will help you land on a model that is a good complement to your setup.
