Robot vacuums are impressive devices that will clean your floors well and — thanks to bigger batteries and better robot brains — rarely get tired of doing their job. Over the last few years, they have gone from being utilitarian devices that sweep your floor to full-fledged home robots that can vacuum and mop your home and then trundle off to clean themselves to be ready for the next run.
I’ve been testing robot vacuums for seven years and have run over 70 robot vacuums all over my house. These are my top picks if you’re looking for the best: a robot vacuum that can do it all with limited intervention from you.
Along with my top picks, I have options to fit specific needs, such as mopping or besting pet hair. The good news is there are a lot of great options. Whether you have a 3,000-square-foot home and three shaggy dogs or a small, stylish apartment you share with a goldfish, there’s a robot vacuum to suit your needs.

What I look for How I test robot vacuums Collapse I test robot vacuums constantly. At any time, there are seven or eight of these busy little bots roaming my floors. Alongside everyday use, I put them through a gauntlet of specific tests. This includes testing object detection and avoidance with phone chargers, socks, a pencil, and fake pet poop. I throw in Cheerios or popcorn to see if they know to vacuum that up rather than avoid it. I also run them over oatmeal and flour to see how well they pick up fine debris and have them tackle both thick and low-pile carpets. I watch to see how they handle rug tassels, skinny chair legs, and room transitions.For mopping prowess, I test them on hardwood and tile floors with dried milk, fresh OJ, and ketchup. I monitor how quickly they fill up their bin / auto-empty dock and how efficiently they use water and clean their mop pads.I also set schedules, hook them up to voice assistants, and play with any advanced features in the app. I evaluate how well they map and how easy the maps are to edit and use, as well as test and unique features such as home security camera capabilities, AI cleaning programs, and auto-mop removal.. Cleaning and mopping power Collapse It’s not all about suction. In my testing, the brush is also a big factor in how well a robot will clean your floors. A large rubber roller brush is much better than a small bristle brush at picking up debris. It’s also less prone to getting tangled up with hair. Two brushes are better than one, and a brush housing that has some flexibility — so it can move with the contours of the floor — is also more effective.It’s hard to find a robot vac that doesn’t have some form of mopping, but not all mops are created equal. I looked for mopping bots that could get up dried-on stains, like milk and ketchup, and scrub up small wet spills without messing themselves up. Oscillating, spinning, or vibrating mop pads clean better than bots that just drag a wet rag around, but the new self-cleaning roller mops that are beginning to appear are even more effective. Auto-carpet sensing is also important since it prevents the robot from accidentally mopping your rug. Convenience Collapse A big bin means you don’t need to empty it as often. The largest I’ve seen is 800ml, but anything over 500ml is decent. With many bots now pulling double duty as mopping robots, plus the popularity of self-empty dock / charging bases, it’s getting harder to find small robot vacs with big bins. But they’re worth considering — especially if you have carpets and pets. I love self-empty docks, but sometimes you don’t have space for them, and if you like your robot to be out of sight (living under your bed or sofa), you’ll want a big bin and no dock.Self-emptying docks are becoming standard now and coming down in price (thankfully). A self-empty dock turns the charging base for your robot into a motorized emptying station that sucks out the dirt from its bin. (Warning: this process can be loud!) This saves you from having to pull out the bin after every few runs and empty it yourself. Instead, you’ll have to replace the bag (and buy new ones) when it gets full, generally about once a month. Many robots now have a self-empty dock option you can add later, although buying them together is generally cheaper. How smart they are Collapse Another nice-to-have feature, AI-powered obstacle detection helps your robot “intelligently” detect and avoid clutter (and a potential poop apocalypse if it encounters pet waste). These models use cameras (worth noting) to see objects in their path and onboard processors to “decide” how to approach them based on what they see. All AI is not created equal, however, and some are much better at this than others. The end result is that robot vacuums with AI detection are less likely to get stuck when cleaning, so you’re more likely to come home to a clean floor rather than a beached bot.A robot that maps your house will get into every nook and cranny better than one that bumps and rolls around. Mapping also lets you send the robot to clean specific rooms rather than the whole space and add virtual walls to prevent your bot from going where you don’t want it to. These are crucial if you have delicate objects or areas in your home that regularly trap robots. Most robots use variations on simultaneous localization and mapping (SLAM) technology, such as lidar or vSLAM. Are they easy to use? Collapse A good app has easy controls to stop and start your vacuum, scheduling options (including do-not disturb hours), plus good mapping features. Nice-to-have features are room-specific cleaning and settings (so you can tell your vacuum to clean the kitchen or have it mop and vacuum the kitchen but only vacuum the living room). My biggest frustration with apps is maps that are fiddly to update and / or crash and must be rebuilt constantly. Most vacuums now have voice control (see FAQs), but some offer more in-depth control, such as telling Alexa to have the robot clean twice under the dining room table. Good battery life and repairability Collapse Nearly all robot vacuums can “recharge and resume” — take themselves back to their dock when they’re low and recharge before picking up where they left off. But a vacuum with at least 120 minutes of runtime (180 is ideal) will clean the whole house in one go. If it takes too long, noisy robots that are constantly running will get shut off by annoyed family members who aren’t about to clean the room for you.Robot vacuums are quite an investment, and it’s important to be able to buy replacement parts to keep them going for longer and have access to good support in case your robot has a serious issue.

Roborock’s S8 MaxV Ultra ($1,799.99) is an exceptional vacuum cleaner and a very good mop. Its dual rubber roller brushes and 10,000Pa suction make it great on carpets; its sonic mopping is very good on hard floors, and its improved AI-powered obstacle detection means it will most likely get the job done without getting trapped or derailed.
The S8 MaxV Ultra is the best in the category of “hands-free” robot vacs, bots that do virtually everything for you: empty their bins, refill their mop tanks, and clean and dry their mop pads. Roborock invented this category with the S7 MaxV Ultra and has been steadily improving it.
