Score: 82/100
Mamibot W120-DP
Score: 81/100Rankings
The ECOVACS Winbot W2 Omni is a portable window-cleaning robot with industry-leading suction and up to 110 minutes of untethered runtime. Its heavy system weight, variable runtime claims and long charging time are notable trade-offs. Best suited for tall-window homeowners who need safe, outdoor-capable cleaning.
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 commend the W2 PRO OMNI for its industry-leading safety architecture, long untethered battery life and the ability to clean large glass areas quickly and quietly. The portable OMNI station is highlighted as a differentiator that enables true outdoor use, while the robot matches the performance of the larger W2 PRO model but with added portability and a slightly quieter acoustic profile.
Everyday users consistently praise the robot's ease of use, reliable cleaning results and the convenience of cleaning high or outdoor windows without ladders. The long battery life and quiet operation are frequently mentioned as positives, while a few customers note the heavy package and occasional variability in runtime as minor drawbacks.
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.
