Liectroux S9 Robot Window Cleaner — Smarter, Stronger, Safer

Say goodbye to the hassle of manual window cleaning. The Liectroux S9 is an intelligent robot window cleaner engineered for deep, streak-free results on frameless and framed glass alike — all with minimal effort from you.

Unmatched Suction & Cleaning Power

With 10,000Pa of suction from a brushless motor, the S9 locks firmly onto glass surfaces and doesn't let go. Dual roller brushes paired with high-density fibre mops deliver deep cleaning without scratching, while the separate air duct design extends the motor's lifespan for long-term reliability.

6-Way Water Pump Spray System

Three nozzles on each side deliver precise, even water distribution across the glass. Unlike atomising blade systems, the pump-driven spray is suitable for multiple cleaning media and virtually clog-free — keeping your windows consistently clean session after session.

Intelligent Navigation & 5 Cleaning Modes

Gyroscope-guided navigation lets the S9 clean in efficient Z and N patterns, with five modes to choose from: N, Z, N+Z, Edge Cleaning, and Fix-Point Cleaning. Fourfold frame detection and eight micro-switches across all four corners ensure the robot recognises borders and adjusts direction automatically — even on frameless glass.

Safety You Can Count On

The S9 is built with multiple layers of protection. A built-in 600mAh UPS battery keeps the robot adhered to the glass for up to 30 minutes in the event of a power cut. The moment an air leak is detected, it retreats automatically. A combined power cord and safety rope (5.2m) prevents tangling while keeping the robot secure at height.

Full Smart Control

Operate the S9 via the Tuya / Smart Life app or the included 2.4GHz remote control with a range of up to 20 metres — no directional limitations. Voice prompts keep you informed throughout the cleaning cycle.
