HUTT W8
Our Verdict: The AI dirt detection is a genuine differentiator — it spends more time on dirty spots instead of treating the whole window the same.
The HUTT W8 introduces AI dirt detection to window cleaning. Its sensors identify particularly dirty areas and automatically increase suction and spray output for targeted deep cleaning, then reduce power on cleaner sections to conserve water and reduce noise.
Adaptive Cleaning
Suction auto-adjusts between 1,850Pa and 3,800Pa based on real-time dirt detection. This intelligent approach means the W8 spends more time where it’s needed and moves efficiently through cleaner areas. Dual spray nozzles and an 80ml water tank support approximately 35m² of cleaning per fill.
Quiet and Efficient
At 65dB, the W8 is quieter than most window robots. Its compact 241 × 241 × 83mm body at 1.41kg feels well-balanced on the glass, and the 30-minute UPS backup provides safety during power outages.
