Mamibot W120-DP
Score: 81/100Rankings

The Hobot-298 is an AI-driven window cleaning robot that excels on large, frameless glass with ultrasonic mist spray and fast cleaning speed. Its small water-tank capacity and the need for a safety rope limit convenience on smaller panes. Best suited for homeowners with big windows who prioritize speed and streak-free results.

The Mamibot W120-DP is an ultra-slim, lightweight robot window cleaner with strong suction and a sophisticated 4-nozzle spray system. Its small water tank and limited battery backup restrict continuous cleaning time, especially on larger windows. Ideal for homeowners with large, accessible windows who value a sleek design and advanced controls.

Professional reviewers consider the Hobot-298 an advanced, AI-driven window cleaning robot that excels on large, frameless glass surfaces. They commend its ultrasonic mist spray, fast cleaning speed, and low-noise motor, while noting that optimal performance still depends on using a detergent and that the device is less suited for small panes.
Everyday users praise the robot for making large-window cleaning effortless, quiet, and streak-free thanks to the mist technology. Common complaints revolve around the need for detergent on tough grime, the effort required to set up the safety rope, limited water-tank capacity, and occasional app or remote connectivity issues.

Professional sources describe the W120-DP as a cutting-edge 6th-generation model that pushes the limits of slimness and sensor integration, highlighting its auto-adjusting suction and motorized spray as notable advances over previous generations, though independent testing data is lacking.
