Hobot HOBOT-298
Score: 81/100
Fmart W8 Mini
Score: 76/100Rankings

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 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.

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.
