Setup
- Attach Cleaning Cloths: Secure the microfiber cleaning cloths to the bottom of the HOBOT 188 unit. Ensure they are properly aligned and cover the cleaning pads.
- Connect Power: Plug the power adapter into the HOBOT 188 unit and then into a power outlet. The unit requires continuous power during operation.
- Secure Safety Rope: Attach the safety rope to a sturdy fixture indoors, such as a heavy piece of furniture or a window frame. This is crucial to prevent the device from falling in case of power loss or suction failure. The safety rope has a tensile strength of 150Kgf.

Operating Instructions
- Power On: Place the HOBOT 188 on the glass surface you wish to clean. Ensure the unit is centered and has good contact with the surface. Press the power button on the unit or the remote control. The robot will create suction and adhere to the glass.
- Select Cleaning Mode: Use the remote control to select one of the three automatic operation modes for cleaning the entire window. The HOBOT 188 will automatically detect the edges of the window and plan its cleaning path.
- Monitor Progress: The robot will clean the surface at a speed of approximately 4 minutes per square meter. It will stop automatically upon completion of the cleaning cycle.
- Emergency Power System: The HOBOT 188 is equipped with an embedded UPS (Uninterrupted Power System). In case of an accidental power off, the device can still absorb to the surface for approximately 20 minutes, allowing time for retrieval.
- Versatile Use: The HOBOT 188 is suitable for various smooth surfaces including windows, seamless tiles, frameless mirrors, and glass doors. It can also be used in a table cleaning mode for horizontal surfaces.

Maintenance
- Clean Microfiber Cloths: After each use, remove the microfiber cleaning cloths from the HOBOT 188. They can be hand-washed or machine-washed with mild detergent. Ensure they are completely dry before reattaching for next use.
- Inspect Suction Rings: Periodically check the suction rings for any debris or damage. Clean them gently with a damp cloth if necessary.
- Store Properly: When not in use, store the HOBOT 188 in a cool, dry place, away from direct sunlight and extreme temperatures.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Robot loses suction and falls. | Power cord disconnected; suction pads dirty; surface too porous. | Ensure power cord is securely connected. Clean suction pads. Use on smooth, non-porous surfaces. Always use the safety rope. |
| Cleaning performance is poor. | Cleaning cloths are dirty or worn; insufficient cleaning solution; extremely dirty surface. | Replace or clean microfiber cloths. Apply appropriate cleaning solution. For very dirty windows, perform a dry clean first, then a wet clean, or multiple passes. |
| Robot does not clean corners effectively. | Design limitation due to circular pads. | The HOBOT 188 may not reach the innermost corners due to its design. Manual touch-up may be required for perfect corner cleaning. |
| Remote control is unresponsive. | Remote control batteries are low or depleted; obstruction between remote and robot. | Replace remote control batteries. Ensure a clear line of sight between the remote and the robot. |
