Vacuums and mops, then cleans the mop pads itself with hot water.
$899 at Amazon Read the full reviewThe short answer
- The Robomop P7 is the best robot for most homes with pets: the most hair collected and only two rescues in 20 runs.
- The Clean Bot Mini costs $229 and is fine for a small, tidy apartment, but it drives randomly and can’t clean one room at a time.
- The Robomop P9 Ultra is the only one that really mops, and the best at avoiding obstacles.
- Pickup barely improves above $500. You pay for mopping, maps and fewer rescues.
How we compared them
Every robot cleaned the ground floor of our test house in Columbus 20 times over five weeks: oak in the kitchen, a low-pile rug in the living room and tile in the hall. Our cat and dog supplied hair every day, and before each measured run we added a fixed hair mix so every robot faced the same amount.
We weighed what each robot collected, counted every time it needed rescuing, and measured runtime and noise ourselves. We bought every robot at retail price; no manufacturer saw this comparison before publication.

Frequently asked questions
Is a more expensive robot vacuum cleaner?
Only up to a point. In our test, pickup barely improved above $500. The extra money buys mopping, obstacle avoidance and a station that does more of the maintenance.
Do I need a self-emptying base?
With pets, yes: without one you empty a small bin after almost every run. In an apartment without pets you can do without.
Do any of them need a subscription?
No. Mapping, scheduling and room cleaning are free in all of the apps.
