- Runtime
- Up to 100 min on hard
A simple, very slim robot for small homes that just want daily crumbs and dust handled on a budget. Reviewers found its suction good for the price, but it has no app, no mapping and no auto empty, and it bounces around at random. Spend about $80 more on the Roborock Q7 M5+ if you want mapping and a dock.

- iPath laser navigation
- Mopping
- Dual rotating pads
- Runtime
- 101 min sweep and mop
One of the cheapest robots with a dock that empties, washes and dries its pads, and its 3.35 in body fits under low furniture. Testers found strong bare floor and mopping results, but it has no real obstacle avoidance, a tiny dustbin and short coverage per charge. Skip it for cluttered homes or long hair.

What reviewers found
Eufy 11S Max
- TechHive: The jump to 2,000 Pa lifted more crumbs and pet hair, especially on carpet, and it crossed carpet to hardwood smoothly. It navigates by driving straight and turning on contact, so cables should be tidied. Source
- The Ambient: Removed most of the dirt in its runs and was very quiet in standard mode, but with no app or mapping it bounced around at random, choked on cables and got wedged between chairs. Source
- Mighty Gadget (87%): Left a full bin after each room and rarely caught on cables; the reviewer did not run formal suction tests. Source
eufy Omni C20
- Vacuum Wars (2.21 Vacuum Wars stars): Removed 96% of flattened pet hair and 75% of embedded sand, scored 227 on mopping against a 171 average, but 54% of long hair wrapped the brush and it covered only about 525 sq ft per charge. The page header shows 2.21 stars while its verdict text cites 3.09. Source
- RTINGS: Great on bare floors and along walls, only okay on carpet and passable on pet hair. Struggled with power cords and gave weak stain removal because the robot has no water tank of its own. Source
