HOBOT HOBOT-388
HOBOT-388 Automatic Smart Window Cleaning Robot User Manual
Model: HOBOT-388
1. Introdución
The HOBOT-388 is an automatic smart window cleaning robot designed to efficiently clean glass surfaces. It features an ultrasonic water spray nozzle, a brushless DC motor for quiet operation, and can be controlled via a smartphone application or remote control. This manual provides essential information for the safe and effective use, setup, operation, and maintenance of your HOBOT-388.
2. Instrucións de seguridade importantes
- The HOBOT-388 operates exclusively with its power cord connected. An embedded Un-interrupted Power System (UPS) prevents the robot from falling during a power interruption.
- Do NOT use the robot on windows with non-rectangular (rounded) edges, as this may compromise suction.
- Ensure the surface size is at least 13 x 13 inches (approximately 33 x 33 cm) for proper operation.
- The robot is suitable for glass thickness of 3 mm or more.
- Always attach the safety cord to a secure anchor point before operating the robot, especially on exterior windows.
- If the robot does not move upwards effectively, ensure cleaning cloths are adequately sprayed with cleaning solution. This can occur on very clean windows.
- Avoid using the robot in high humidity conditions or during rain, as moisture can affect suction and cleaning performance.
