Compact window cleaning robot designed for automatic, hands glass cleaning. It uses brushless motor drive and vacuum adsorption to hold securely to vertical glass while simulating manual wiping for consistent results. Key benefits Strong, reliable adhesion: German vacuum adsorption technology provides up to 5 kg of vertical suction force to keep the robot fixed to glass during operation. Consistent cleaning performance: brushless motor and twowheel rotation gently wipe without scratching while following an automatic navigation path for full coverage. Powerfail protection: builtin UPS with a polymer lithium backup battery offers about 20 minutes of continued adsorption after mains failure to reduce the risk of falling. Fast coverage: cleans at about 0.4 square meters per minute, reducing the time required compared with manual cleaning. Easy control and setup: includes a remote control for convenient operation and automatic edge detection to handle window edges safely.

Vacuum adsorption technology for secure attachment to vertical glass. Automatic edge detection and simulated manual wiping motion for thorough cleaning and minimal streaking. Twowheel rotation system gently wipes without scratching. Automatic path planning and to bottom after finishing the cleaning cycle. Remote control for start, stop, and directional commands. UPS and backup battery provide continued adhesion and controlled shutdown in case of power loss. Practical use scenarios Residential windows: cleans tall or hardtoreach glass panels, sliding doors, and balcony enclosures where manual access is difficult. Office or commercial glass partitions: maintains interior glass walls and large windows with less labor and consistent results. Shower doors and glass enclosures: suitable for flat glass bathroom surfaces that meet the size and flatness requirements. Compatibility and limitations Intended for use on flat, even, and level glass surfaces larger than 35 cm by 35 cm. Not designed for textured, perforated, or nonflat glazing surfaces. Follow safety rope attachment and remote control instructions to ensure safe operation. Safety and operation notes Always secure the included safety rope before operation and ensure the backup battery is charged for added protection. Keep power adapters and extension cables connected according to the included specifications. cleaning pads and wheels as needed to maintain cleaning performance. This compact window cleaning robot combines vacuum adhesion, brushless motor drive, automatic navigation, and a UPS backup to provide a practical solution for routine glass cleaning where surface requirements are met.
