The MAMNV T7S takes versatility to the next level as a 2-in-1 vacuum and mop combo. It features separate water and dust tanks, allowing users to simultaneously vacuum and mop hard floor surfaces for thorough daily upkeep.

But its navigation needs a lot of work. If you have a simple floor plan with a lot of carpets, it is worth considering, but the short battery life and lack of an Automóvel-empty dock are major cons. Read more in this hands-on.

Its sonic mopping system — which vibrates its mop pad 4,000 times a minute — ably simulated scrubbing and wiped out my OJ and ketchup tests, though I did have to set it to deep scrub.

Big-brand robovacs that are a couple of years old can often deliver the best value for money, with very few sacrifices in performance. And sales events like the Black Friday deals generally come through with strong discounts in this category too.

A 2024 study from Roskilde University in Denmark explored how householders’ experiences with robot vacuum cleaners compared to their experience with manual vacuum, and found that "robotic vacuum cleaners are inferior in use, yet transform vacuuming".

At Consumer Reports, we’ve done the testing for you. In our labs we evaluate each vacuum on how well it picks up debris from carpets and bare floors, and how well it captures pet hair. Depending on the vacuum type, we also assess how easy it is to use, how noisy it is, how strong the suction is, and how clean its emissions are, among several other criteria. If you’re not sure which type of vacuum to get, know that canister and upright models are the best picker-uppers for everything from embedded dirt to piles of pet hair.

These are becoming standard now and coming down in price (thankfully). A self-empty dock turns the charging Top 3 Automatic Vacuum Cleaners base for your robot into a motorized emptying station that sucks out the dirt from its bin. (Warning: this process can be loud!

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.
