A capable, low maintenance flagship with strong carpet cleaning, spill detection and a hair cutting system that kept brushes clean in testing. It is slow, and Tom's Guide saw it miss corners and catch wires. Skip it if you pay near full price, since it was sold out with deep checkout discounts when we checked.

- Mopping
- RevoRoll roller mop
The S10 is for people who want a robot that fills and drains its own water from a nearby sink or laundry line, and testers rated its roller mop highly. Navigation and object detection are weak, it is tall and wide, and setup takes more work than a normal dock. At full price it is expensive, so wait for a sale or look at the newer S20.

What reviewers found
Eureka J15 Max Ultra
- Tom's Guide: Vacuumed 602 sq ft in 72 minutes, leaving 65% battery. Mopping about 350 sq ft took nearly two hours. Skipped about 168 sq ft on one run and caught on lamp wires and carpet corners. Cited $1,199.99 at Eureka. Source
- Android Authority: Strong on carpets and pulled pine needles from rugs. No hair tangles. Water tanks needed swapping about every 1,000 sq ft. Mop pads popped off magnetically on bath mats, once four times in a day. Called it the best Eureka it has tested. Source
SwitchBot S10
- Android Authority (AA Recommended): Three weeks of daily vacuuming and mopping three times a week ran hands off when plumbed in. The bot was about an inch too wide for the tester's chair legs and about half an inch too tall for some cabinets. Source
- The Hook Up: Called it the second best mopping performance the reviewer had measured, behind the Eufy S1 Pro, but noted weak object detection and navigation and a mop roller that does not lift high enough for high pile carpet. Source
