Overview

The LIECTROUX G9 is a dual-engine window cleaning robot designed for comprehensive automated glass maintenance. Featuring an industry-first dual-arm cleaning system that simulates human-hand pressurized wiping, it effectively removes stubborn dirt and water stains from framed and frameless surfaces. The compact 265mm square design integrates advanced safety systems including 10000Pa suction and quadruple anti-fall protection, making it suitable for high-rise windows and large floor-to-ceiling glass installations.

Advanced Cleaning Technology

Unlike conventional single-pad robots, the G9 utilizes dynamic pressure-control technology with dual cleaning arms that automatically adjust scrubbing force based on surface conditions. The 8-nozzle high-pressure spray matrix combined with pulse-pump technology creates uniform water coverage to soften dried grime before wiping. Four dedicated edge and corner brushes spin at 200 RPM to break apart dirt buildup in window frames and narrow gaps, ensuring no missed spots around borders.

Smart Control & Navigation

Intelligent route planning automatically detects window dimensions and selects optimal cleaning paths from seven available modes including N-pattern, Z-pattern, and deep cleaning. The robot features return-to-start functionality for easy retrieval after completing its cycle. Users can control operations via the Tuya Smart App over Wi-Fi or the included 2.4GHz wireless remote, while built-in AI voice prompts provide real-time status updates throughout the cleaning process.

Safety & Power Systems

A premium brushless variable-frequency motor generates 10000Pa hurricane-force suction, maintained by a Dynamic Pressure-Stabilized Mobility System that compensates for pressure changes within 0.03 seconds. The quadruple anti-fall system incorporates optical coupling sensors, current and air pressure monitoring, plus four edge sensors. An integrated 500mAh battery provides UPS power-off protection for up to 30 minutes during outages, preventing falls even when disconnected from wall power.

What’s in the Box

The package includes the G9 Window Cleaning Robot main unit with integrated 120ml water tank, one AC power adapter supporting 100-240V input, one power cord, and one water filling bottle for the spray system. The remote control with batteries and user manual are also included to ensure immediate operation out of the box.
