It has four cleaning modes and can be controlled with a remote or through the Tuya and Smart Life apps.
Dimensions and power
The cleaner measures 24 × 24 × 8 cm and weighs approximately 1.6 kg. Its compact dimensions make it easier to handle and store, although smaller windows need enough space for the device to move.
The motor is rated at 72 W. The power supply supports an input of 100–240 V AC at 50–60 Hz. This voltage range allows use on different electrical systems, but plug compatibility with local sockets must be checked separately.
Cleaning and modes
The 8000 Pa suction pressure helps the device adhere to glass while cleaning. Automatic spraying in four directions wets the surface from multiple directions.
The S11 has four modes that can be selected according to the surface and the dirt being cleaned:
- Z and N: cleaning in the corresponding movement pattern.
- Edge: cleaning around the edges.
- Spot: cleaning a particular area.
For example, Spot mode can be used for a localised patch of dirt, while Edge mode is intended for the edges of a window.
Controls
The Tuya and Smart Life apps let users start or stop cleaning and change modes from a smartphone. Alternatively, a 2.4 GHz remote control allows operation without a phone.
Backup battery and safety
The Liectroux S11 has a 500 mAh battery rated at 14.8 V. A UPS backup time of 30 minutes is stated, but it is not specified which functions remain active throughout that period. It should not be assumed that the robot will continue cleaning for 30 minutes after a power outage. Battery life during normal operation is not stated.
The device also has a four-level anti-fall protection system. Follow the manufacturer's safety instructions, particularly when using it on windows at height; neither backup power nor anti-fall protection should be treated as a guarantee against an accident.
The S11 is an option for households looking to automate glass cleaning and choose between several modes. Its dimensions, power requirements and the unspecified conditions behind the stated 30-minute backup are worth considering.
