Score: 81/100
Fmart W7
Score: 77/100Rankings

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 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 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 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.
