It features innovative ultrasonic water spray technology, AI smart route planning, and dual replaceable water tanks, ensuring thorough cleaning without leaving water stains. This manual provides detailed instructions for the safe and effective use of your HOBOT-2S.
2. Safety Information
Please read all safety instructions carefully before operating the HOBOT-2S to prevent injury or damage to the device.

8. Troubleshooting
If you encounter issues with your HOBOT-2S, refer to the table below for common problems and solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Robot loses suction or falls. | Air leakage, dirty cleaning cloths, uneven surface, non-rectangular frame edges. | Ensure cleaning cloths are clean and properly attached. Check for any obstructions or unevenness on the glass. The edge-leakage sensor technology detects slight lifts; ensure proper contact. Do not use on rounded edges. |
| Streaks left on glass. | Dirty cleaning cloths, insufficient or incorrect cleaning solution, clogged spray nozzles. | Replace or clean cloths. Use distilled water or HOBOT-approved solution. Check and replace water tanks/nozzles if clogged. Run a dry cycle first on very dirty windows, then a wet cycle. |
| Robot not moving or stuck. | Power cord obstruction, insufficient suction, minimum area not met. | Ensure power cord is free. Verify strong suction. Confirm cleaning area is at least 15x15 inches. |
| Water leakage from tank. | Improperly sealed tank, damaged tank. | Ensure tank caps are tightly closed. If leakage persists, replace the water tank unit. |
| Robot does not go up. | Tread issue, suction problem. | Ensure cleaning cloths are clean and not hindering tread movement. Check for sufficient suction. Contact support if problem persists. |
The Edge-Leakage Sensor technology helps detect air leakage around window seals or frameless window edges, aiding in troubleshooting suction issues.
