CHOVERY CL3
Budget window robot with dual-side spray, 2,700–3,300Pa suction, and 30-min battery backup.
Mamibot W120-DP
Our Verdict: The thinnest window robot available at 69mm — ideal for tight spaces and recessed windows, with solid cleaning to match.
The Mamibot W120-DP is the flagship model from this USA-based manufacturer, featuring the thinnest profile in the market at just 69mm. Four two-way spray nozzles and a 60ml water tank deliver cleaning solution from both directions for even coverage.
Ultra-Thin Profile
At 69mm thin, the W120-DP fits in spaces other window robots can’t reach. The variable frequency 3,200Pa suction adjusts power automatically based on the surface, while multiple AI cleaning patterns (N, Z, Z+N, Spot, X2) ensure systematic coverage.
Long Battery Backup
A lithium battery backup provides 25 minutes of sustained suction during power outages, 5 minutes more than most competitors. Available in blue, grey, and orange colourways.
