Who it suits
Best for cleaning under low beds and sofas: 3.35 in, ahead of 76% of the 63 robot vacuums we track that publish it. The trade-off: a small mop lift, so the mop can touch low rugs (10.4 mm, behind 90% of them).
What the maker says the eufy Omni C20 does
Mopping
It mops with two spinning pads. It lifts the mop 10.4 mm when it reaches a rug. (maker page)
Mop upkeep
The dock washes the mop. The maker does not say the dock dries it, so check the pad does not stay damp. (maker page)
Obstacle avoidance
It spots objects in its path with infrared (maker page).
Dock
Empties itself into a bag: about 60 days per bag, 3100 ml bag. (maker page)
