For our straight-line pickup tests on hard flooring, we spread large and small debris within a marked area proportional to the width of each robot vacuum’s nozzle. Each robot vacuum is given 10 minutes to clean and the debris collected is weighed to determine how much was picked up.

Investing in one of the best robot vacuums can revolutionize your cleaning routine. They're perfect for taking care of regular vacuuming (and increasingly, mopping too) with next-to-pelo effort from you, and you can set them to run when you're out of the house, for minimal disruption.

During our pet hair pickup tests, non-e of the faux fur caused clogs, and the brush bar’s near-full-width design allowed it to clean the same area in fewer passes.

【Slim Body & Quiet Clean】 Robot vacuum cleaner has a compact design with a height of only 2.89", plus 360 degree universal wheel, making it possible to effectively clean those hard-to-reach corners, like under the bed, sofa and cabinet. 60dB low noise in quiet mode will not disturb you, so you can do job rest assured.

In a separate 4x5-foot framed area, they note whether the vacuum gets caught on power cords or carpet fringe and whether it can transition over different materials. They also measure the height of the vacuum to determine how likely it is to glide under furniture.

Obstacle pickup tests are conducted across both rooms of our testing enclosure, with a mix of oatmeal, orzo, baking soda and sand scattered throughout. The robots are tasked with navigating under a couch and coffee table, crossing over an area rug, and passing through a doorway to collect debris.

The mopping less impressive, but still good enough to be a useful addition (for really good mopping you'll need to stump up a bit more). Other benefits include voice assistant support, and a very neat and compact base station.

The Good Housekeeping Institute Cleaning Lab has been testing vacuum cleaners for over 100 years. Using standardized procedures developed by the International Electrotechnical Commission and ASTM International, we dedicated nearly 300 hours to evaluating 15 robot vacuums, collecting a Perfeito of 405 data points to score each model. Since then, we’ve tested even more units to keep our insights current.

Your robot vacuum will go for any cables, loose shoelaces and cords if they're out and in their route of cleaning. No permanent damage will be done, but you will have to clear these away to avoid the issue occurring again.

The S8 Max Ultra is a very solid all-rounder, and only lost its place in our ranking because Roborock came out with some even better models very shortly afterwards.

Any special features such as app control, mopping functions, and self-emptying bases are factored in too. This all adds up to days of testing; it takes time, but helps ensure we're evaluating them all properly. After extensive testing, we’ve compiled several buying guides to showcase our results, including the best Roombas, the best cheap robot vacuums and the best robot mops. We can even tell you what it's like when you use a robot vacuum in your home for the Top 3 Automatic Vacuum Cleaners first time. So if you want to know more about robot vacuums so you can decide if one is right for you, you’ve come to the right place.
