The Mamibot W120-DP edges out thanks to superior suction and affordability. See on our product page.
Manual window cleaning takes hours and poses fall risks—especially above the first floor. These bots climb glass using vacuum suction or adhesion, scrubbing with microfiber pads or sprays. Key factors we prioritized: safety sensors to prevent drops, edge-hugging paths for no-miss spots, and self-spraying for grime like sap or fingerprints. In our tests, top models cut cleaning time by 80% while leaving zero streaks.
At 241 x 241 x 99mm and just 1kg, the Hobot S7 Pro is sleek and portable, with a glossy white chassis that resists fingerprints. The standout 240ml transparent tank sits atop, auto-dispensing solution as pads spin at 330 RPM—double the speed of basic models for deeper cleans.
Dual microfiber cloths cover 100% of the surface, and AI-driven sensors detect frames up to 25mm deep. A tether supports 6m heights, with ultrasonic edge detection stopping precisely 2mm from seals. Build feels premium, but the plastic scratches if mishandled.
Pros:
Cons:
Wi-Fi pairing takes under 2 minutes. The Hobot app offers three modes: Standard (quick pass), Intensive (double scrub for dirt), and Edge (frame-focused). Schedule weekly runs or control remotely—perfect for vacation homes.
Voice integration with Alexa and Google shines: "Hey Google, clean the windows." Safety tether clips securely, and drop sensors halt instantly. No dry mode limits versatility for pre-rinsed glass.
Pair it with a full home clean using the ECOVACS DEEBOT X11 OmniCyclone.
Over 10 sessions on 30 windows (dirty, framed, frameless):
It excelled on frameless but slowed 10% on deep frames. Maintenance: Rinse pads post-use; tank refills in seconds.
Test Scores:
Overall, it's reliable for most homes but shines brightest in modern setups.
If value matters, the Mamibot W120-DP outperforms with 3200Pa suction gripping slick surfaces better. Four spray nozzles ensure even wetting, and modes include intensive for grime. App/remote combo plus edge tech gets 1mm closer than Hobot.
