eufy Omni C20
Slim 3.35 in mop washing robot for low furniture, under $400
Researched by Riley Hart · updated Oct 30, 2026
Is the eufy Omni C20 worth it? 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. It costs $380 as of Oct 30, 2026, and 2 independent reviewers tested it.
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.
Best for: hard floor homes with low furniture on a budget. Skip if: you have cords, toys or long hair on the floor.

- 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.
- Vacuum Wars · 2.21 Vacuum Wars stars
- 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.
