Window cleaning robot Riff HCR31 with 2-side spraying

The Riff HCR31 window cleaning robot with 2-side spraying automates cleaning of glass and other smooth vertical surfaces. The device dispenses cleaning solution from both sides as it moves, allowing continuous wet cleaning without frequent manual reapplication. Designed for routine maintenance of home and office windows, mirrors and glass doors, the robot reduces manual effort and delivers consistent results across multiple passes.

Advantages

The two-sided spraying system ensures even distribution of cleaning solution along the travel path, improving stain removal and reducing streaks. The robot’s automated traversal and suction-based adhesion maintain stable movement on vertical surfaces, minimizing the need for physical handling. Compact dimensions and an integrated reservoir simplify setup and refill procedures, while programmable or automatic modes enable scheduled or one-pass cleaning routines.

Suitable for

• Home and apartment windows
• Office glass partitions and doors
• Bathroom mirrors and shower glass
• Large storefront windows and display cases
• High or hard-to-reach glass surfaces for routine maintenance

Key specifications

• Two-side liquid spraying for continuous wet cleaning
• Suction-based adhesion for vertical surface operation
• Integrated cleaning solution reservoir
• Compact and lightweight design for easy handling
• Multiple cleaning modes including automatic traversal

How to use

Fill the integrated reservoir with an appropriate glass cleaning solution, secure the robot to the target surface and select the desired cleaning mode. The unit will adhere to the glass and start moving while spraying solution from both sides and wiping or polishing along its path. Monitor the operation from a safe distance and pause the device before removing it to avoid streaking. Follow manufacturer instructions for power connection and safety interlocks.

Usage recommendations

Use a mild, non-abrasive glass cleaner to prevent residue and protect surface coatings. For best results on heavily soiled glass, pre-treat localized stains manually before operating the robot and perform regular reservoir cleaning to avoid nozzle clogging.
