Fmart W7
Score: 77/100Rankings
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 W7 combines 4000 Pa suction with dual-sided ultrasonic spray and AI navigation for reliable window cleaning. Its battery runtime varies and reliance on a power cord can restrict fully cordless use. Suited for homeowners and offices with multiple framed windows.

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.
Professional reviewers consider the W7 a solid, no-nonsense window-cleaning robot that delivers strong suction and effective dual-spray cleaning. Its AI-driven navigation and safety tether are praised, but the device is seen as an incremental upgrade rather than a breakthrough, especially on very large panes where runtime and cordless freedom become limiting factors.
Everyday users appreciate the ease of app control, the streak-free results, and the safety features that let them clean high-rise glass without ladders. Recurring complaints focus on the limited battery life, the need to replace consumable pads and nozzles, and occasional assembly errors that affect performance.
