Score: 76/100
Ecovacs Winbot W2 Omni
Score: 82/100Rankings

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 FMART T9PRO features 3800 Pa suction, ultrasonic atomizing spray, and AI navigation with an embedded UPS for uninterrupted cleaning. Documentation is sparse and streaks may appear under bright light. Best for users seeking a compact, feature-rich robot for occasional deep cleans.

Professional hands-on reviewers commend the T9PRO-BL for its powerful suction, AI-driven navigation, ultrasonic spray and safety features, noting its compact size and respectable cleaning speed of 20 sq ft per 10 minutes. However, they criticize the sparse documentation and occasional streaks visible in bright light, suggesting the robot excels in automation but still needs better user guidance and polishing performance.
Everyday users generally praise the robot's strong suction, ease of remote operation, and lightweight design, finding it useful for hard-to-reach windows and quick clean-ups. Recurring complaints focus on the lack of detailed instructions, occasional streaks under sunlight, and a moderate noise level that can be noticeable indoors.

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.
“Instructions are sparse with missing details, requiring user interpretation.”

“May leave visible streaks or residue revealed in sunlight, despite initial good appearance.”
