The Ecovacs WINBOT W2 PRO OMNI is a high-performance window cleaning robot with dual power modes, three-nozzle spray, and advanced navigation, suited for large, tall glass surfaces. Its dependence on a bulky Omni station and higher price make it less portable than simpler models. Best for tech-savvy users who need extensive coverage and robust safety on large windows.
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.
The FMART W8 Mini delivers a powerful 8000 Pa suction in an ultra-slim 21 cm square body with app and remote control. It lacks an integrated battery and detailed performance specs, leaving runtime uncertain. Great for users needing a compact, high-adhesion solution for tight window spaces.

Editors and industry analysts view the WINBOT W2 PRO OMNI as a technically advanced step up from the Mini, praising its larger footprint, higher suction, and the inclusion of an automated spray station. However, they caution that the added complexity, reliance on a heavy station, and higher price make it less attractive for users seeking a simple, fully portable solution.
Users appreciate the robot's ability to handle large, tall windows with strong suction and long runtime, but some find the station bulky and the system less portable than expected.
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.
“praising reliability”
Choose the W2 PRO OMNI if you need true portability and outdoor capability; otherwise the standard W2 PRO offers similar performance with a fixed station.
Choose Ecovacs Winbot if runtime and integrated power are priorities; choose FMART W8 for ultra-compact installations.
