The best robot vacuum for 2024
If you’re going to drop some money on a robo-vac, make sure it’s the right one.
Whether you have kids tracking in dirt on a daily basis or a few fur-shedding pets (or both), a robot vacuum can help keep your home clean. And these smart home gadgets have gotten much better in recent years: they have improved navigation around furniture and other obstacles, many are better equipped to suck up pet hair and some even have mopping capabilities now, too. On top of that, there are more affordable robot vaccums available now than ever before. We’ve tested out dozens of these machines over the years and continue to test the latest models as they become available. Below, we outline what you should know before purchasing a robot vacuum, plus our top picks for the best robot vacuum cleaners you can get right now.
What to look for in a robot vacuum
Wi-Fi connectivity
As we explained in our budget guide, Wi-Fi connectivity is a key feature for most robot vacuums. Some of the affordable devices aren’t Wi-Fi connected, though, so it’s best to double check before you buy cheap. Wi-Fi lets a robot vacuum cleaner do things like communicate with a mobile app, which then allows you to control the device from your phone.
Vacuum suction
Suction power is another important factor to consider. Unfortunately, there isn’t a standard power scale that all robo-vacs adhere to, so it’s difficult to compare among a bunch of devices. Some companies provide Pascal (Pa) levels and generally the higher the Pa, the stronger the vacuum cleaner will be. But other companies don’t rely on Pa and simply say their robots have X-times more suction than other robots.
Floor type
Ultimately, we recommend thinking first about the floors in your home: Do you have carpet throughout, or tile and hardwood floors, or a mix? Robots with stronger suction power will do a better job cleaning carpets as they can get into the nooks and crannies more easily. Some machines have “max” modes as well, which ups the suction power but also typically eats at battery life faster than the “normal” cleaning mode.
Mapping features and object detection
Past a certain price threshold, you’ll find advanced perks like home mapping features, improved object detection and automatic dustbin disposal. Home mapping is exactly what it sounds like: The vacuum uses sensors to map your home’s layout as it cleans, allowing you to send it to particular rooms or areas. Most robo-vacs have object detection, but some will be better than others at actually avoiding things like chair legs and children’s toys. Higher-end models like iRobot’s j7 series even go so far as to promise obstacle avoidance to steer clear of things like pet poop that can potentially ruin your machine.
Robot vacuums with mopping capabilities
We’re also now starting to see more robot vacuums with mopping capabilities. Machines with this feature have a water reservoir either built into the robot’s chassis or as a separate piece that you swap in for the dustbin when you want to mop your floors. It makes the robo-vac more useful if you have hard floors in your home that you like to keep squeaky clean, but it does require more work on your part. Filling and emptying the reservoir remains a human’s job.
Auto-empty station
Finally, for peak convenience, consider a robot vacuum that comes with a self-cleaning base. These are basically garbage bins attached to the machine’s docking station. At the end of each job, the robo-vac automatically empties its small dustbin into the large clean base – that means you won’t have to empty the dustbin yourself and you’ll only have to tend to the base once every few weeks. Just keep in mind that most self-emptying bins require proprietary garbage bags – another long-term expense you’ll have to factor in. Also, any vac-and-mop robot with a water tank will not dump its dirty water into the clean base, so you’ll still have to clean up that yourself.
Shark AI Ultra Robot Vacuum
Best bag-free, self-emptying robot vacuum
Wi-Fi connectivity: Yes | Floor type: All floor types | Features: Obstacle avoidance, home mapping, LiDAR navigation | Assistant support: Alexa/Google Assistant | Mopping capabilities: No | Self-empty: Yes | Good for pet hair: Yes
Shark’s RV2502AE AI robot vacuum with self-emptying base ticks all of the boxes that a mid-range machine should. It offers reliable cleaning performance, its mobile app is easy to use and it produces accurate home maps. On top of that, its base is bagless, which means you won’t have to spend money on extra bags every few months.
Setting up the Shark is as simple as taking it and its base out of the box, plugging the base in and downloading the companion mobile app to finish things up. The machine connects to Wi-Fi, allowing you to control it via the app when you’re not at home, or using Google Assistant and Alexa voice control. The first journey the Shark makes is an “Explore Run,” during which it produces a map of your home that you can then edit from the mobile app.
The Shark produced a pretty accurate floorplan of my two-bedroom apartment, and I was happy to see a “re-explore” option that I could use if the map wasn’t up to my standards. With a completed map, you’re then asked to label rooms in your home. That way, you can send the Shark to only the bedroom for more direct cleaning jobs, select “no-go” zones and more.
The first few times I ran the Shark robot, I had it clean my whole apartment. I was impressed by how quiet it was – or rather, how much quieter it was compared to other robo-vacs I’ve tried. You’ll have to turn up the volume on your TV if it’s cleaning in the same room, but it’ll be hard to hear when it’s sucking up debris down the hallway. It also did a decent job maneuvering its way around the cat toys I left out on the floor. The device’s object detection feature claims it can avoid things as small as four inches, but I found that it was much better at sensing and moving around the three-foot-long cat tunnel on my floor than the many tiny mouse toys.
But even if Mr. Mouse caught the edge of the Shark’s wheels now and then, the robo-vac took it all in stride. One thing I look for when testing robot vacuums is how much attention they need from me during cleanings. The best ones are hands-free and require no extra attention at all – once they start a job, they’re smart enough to putter around your home, move around objects and return to their base when they’re finished. With Shark’s robo-vac, I never had to tend to it when it was cleaning. Now, I did my due diligence and picked up pieces of clothing and charging cables off the ground before running the Shark (ditto for every other robot vacuum I tested), so those things were never in the way. Most companion apps will actually remind you to do this before starting a cleaning job.
This Shark machine comes with an auto-empty station, so it will empty its dustbin after every cleaning run – and also during a job if its bin gets full before it’s done. In the latter situation, the Shark will go back to cleaning automatically after it’s freed up its bin. That’s a great feature, but I found the best thing about the base to be its bagless design. Shark’s device is unlike most other robot vacuum clean bases because you don’t have to keep buying proprietary garbage bags to outfit the interior of the base. When you want to empty the base, part of it snaps off and opens to eject debris, and it easily locks back in place when you return it. Not only is this quite convenient, but it also brings the lifetime cost of ownership down since you won’t be buying special bags every few months.
Its worth noting that Shark has a couple of models that are similar to the RV2502AE that just have a different color scheme, a 30- versus 60-day self-cleaning base capacity and other minor differences. The biggest feature that would impact how you use the machine is the clean base capacity: we recommend springing for the 60-day models if you want to interact as little as possible with your robo-vac.
