Two Sprays. Three Directions. Cleaner Glass. The HOBOT-2S is HOBOT Technology's most advanced window cleaning robot. Where the HOBOT-298 has one spray nozzle, the 2S has two — and they spray in three directions simultaneously, simulating the effect of human breathing on glass. The result is a 15-micrometer dense mist that dissolves dust and polishes windows without leaving watermarks, with no manual effort required.
The Pro's Take: At Yard Automation Pros, the HOBOT-2S is our premium recommendation for homeowners who want the best cleaning result and the most thorough coverage. The 4X Edge-Leakage sensors, 80% corner coverage, and 200 Kgf safety rope represent a meaningful step up from the 298. If you have large glass areas, frameless windows, or just want the most capable robot in the lineup, this is it.
Core Features:
- Dual Ultrasonic Water Spray: Two nozzles spray in three directions simultaneously — a 15μm mist that dissolves dust and polishes glass without watermarks. No manual spraying needed.
- 4X Edge-Leakage Sensors: Detects air leakage from slight lifts at window seals and frameless edges. More precise edge awareness than laser-based systems.
- 80% Corner Cleaning Coverage: Enlarged cleaning cloth design extends coverage deep into corners — double the 40% coverage of the HOBOT-298.
- 6.5 Kgf Suction Power: Brushless DC motor holds the robot firmly on glass while suctioning dust and removing impurities.
- 1.5mm Gap Detection: Detects glass edge gaps as small as 1.5mm for precise edge-to-edge cleaning.
- 200 Kgf Safety Rope: Higher-rated safety rope than the 298. Ties to any indoor fixture before use.
- 20-Minute UPS Emergency Power: Embedded backup battery holds the robot in position with an audio alert for 20 minutes during any power interruption.
- Voice Prompt + Creative Voice: Multilingual voice updates keep you informed of cleaning status in real time. Personalize with different voice characters.
- OTA Firmware Updates: Keep the robot's software current via the HOBOT app — updated over the air without any cables.
- Works on Multi Surfaces: Windows, tiled walls, frosted glass, and smooth vertical surfaces.
