CLEANING PROWESS Very good. It picked up more than half the coffee powder and later returned to the spot to vacuum it up cleanly. It went the closest to chair legs and the foot of walls, and dusted them very well with its swirling brush.
SENSITIVITY TO OBSTACLES Like the Icleobo and Mamirobot, it avoided some low furniture and bumped lightly into others. A rubber bumper strip prevented major damage. It moved between chair legs aggressively but over rugs easily.
EASE OF USE I could start, stop, move and dock the machine with its sleek remote control, but I had to use the machine’s touch screen panel to set its cleaning schedule. It comes with audio instructions and a slide-out dust bin. It’s the only one with a useful handle. NOISE Moderately noisy.
VERDICT Cleans thoroughly, but is a tad noisy and knocks into furniture.
