HUTT W9

Our Verdict: The most sensor-laden window robot available — the 13-sensor array provides genuinely better edge detection than the competition.

The HUTT W9 packs 13 smart sensors for intelligent edge detection and obstacle awareness, combined with HuttHink 4.0 navigation for systematic coverage. Its 3,800Pa suction provides secure adhesion on all glass types.

Sensor Intelligence

Thirteen sensors work in concert to detect window edges, frame boundaries, and cleaning status. The HuttHink 4.0 algorithm uses this sensor data to plan optimal cleaning paths and adjust spray timing for complete coverage.

Generous Capacity

The 150ml water tank is one of the largest in the market, covering approximately 90m² per fill. Four spray nozzles distribute cleaning solution evenly ahead of the microfiber pad. At 2.1kg, it’s heavier than most competitors but this weight contributes to stability.
