Powerful performance with 8000 Pa and an advanced safety system
The foundation of a high-quality window cleaner is its gripping power, and it’s exactly the powerful 8000 Pa suction that keeps the Liectroux S11 firmly attached to the glass even when placed horizontally or vertically. The manufacturer also thought about safety — besides the emergency backup battery (lasting up to 30 minutes after a power outage), you’ll also find air sensors for leak detection and a safety rope, which serves as the final protection against falls.
The S11 is suitable for windows with frames and without, thanks to a system of 8 micro-switches in the corners that precisely detect the edges and never cross the glass boundary. Combined with a gyroscope, it moves smartly in a Z or N shape, thoroughly cleaning the entire surface even in spot-cleaning mode.
Revolutionary 4-way water spraying for perfect cleaning
The Liectroux S11 comes with up to 4 water nozzles, placed two on each side of the device. This system ensures even wetting of the entire surface, increasing cleaning efficiency while also reducing the risk of clogged nozzles.
Spraying works in two modes — automatic and manual. In automatic mode, the robot dispenses water while moving, so you don’t have to worry about anything. The system is suitable for different types of glass, including UV-protected or reflective glass.
Microfiber cloths and gentle cleaning without scratches
The package also includes high-density microfiber mops, which handle grease, built-up dust, and dried-on droplets. The cloths are gentle on glass, so there are no scratches or surface damage. The robot comes right away with 2 mops that can be washed repeatedly and reused.
The motor inside the device is brushless, meaning a longer lifespan, lower noise (up to 65 dB), and reliable operation even during longer cleaning cycles.
Tuya smart app, remote control, and smart functions
Liectroux S11 supports smart control via the Tuya or Smart Life app, available for Android and iOS. With it, you can turn the robot on, set a cleaning mode, or monitor the cleaning progress from another room. Thanks to the 2.4 GHz remote control, you can also manually control the robot to precisely defined areas of the window.
The software recognizes the type of glass and adjusts the suction power accordingly. It also automatically chooses the most efficient cleaning pattern so it covers the entire surface without missing spots. After cleaning is finished, the system parks the robot back where you can easily pick it up.
