Smart Glass Cleaning Robot

The LIESA 311 Automatic Glass Cleaning Robot is designed for users who need a compact machine for recurring vertical-surface cleaning without constant manual wiping. The square housing is built from engineering-grade ABS, while the cleaning system combines dual-side water spraying with N-pattern, Z-pattern and other programmed routes. As a China factory-produced glass cleaning robot, the 311 also integrates air-pressure sensing, water-level detection, edge recognition, automatic air-pressure adjustment and backup power protection into its operating system.

Product Specifications

Product Advantages

1. Square Form for More Direct Corner Access

The Automatic Glass Cleaning Robot uses a square housing rather than a rounded body. This form is designed to work closer to the straight edges and corners of suitable framed glass surfaces, making the cleaning path more practical around areas where a curved housing may leave more distance from the frame.

Its square structure works with the programmed cleaning routes to handle routine vertical cleaning tasks across different window layouts.

2. Dual-Side Atomized Spraying

The cleaning system uses two-sided atomized water spraying instead of relying on water application from a single side.

The two spray directions distribute moisture around the cleaning path and support wet wiping during operation. This is particularly useful when surface dust or adhered dirt needs to be softened before the cleaning cloth passes over the area.

3. 10 Cleaning Modes for Different Movement Patterns

The LIESA 311 provides 10 cleaning modes, including N-pattern, Z-pattern, vertical, horizontal and cross-axis cleaning paths.

Different movement programs give the user more flexibility when working with suitable glass surfaces and different cleaning requirements.

4. Multi-Sensor Monitoring

The robot combines several sensing components, including:

· 6-axis sensor

· Photoelectric sensor

· Water-level sensor

· High-sensitivity air-pressure sensor

These sensors support different parts of the cleaning process, including edge recognition, water-level monitoring and air-pressure detection.

The result is a more coordinated control system rather than a cleaning robot that relies on movement programming alone.

5. Variable Air-Pressure Adjustment

The working air pressure is specified at 2400–2800Pa with variable adjustment.

The system uses air-pressure feedback to monitor the robot's attachment condition and applies an automatic air-pressure adjustment algorithm during operation. This helps the machine respond to changes encountered on suitable vertical surfaces.

6. UPS Backup Suction and 5m Safety Rope

The built-in UPS backup battery can maintain suction for approximately 20–30 minutes after power failure.

A 5-meter safety rope is also supplied as a secondary physical restraint. The two features address different aspects of vertical operation: backup power helps maintain attachment after an interruption, while the rope provides additional physical protection.

7. Lightweight 1.4kg Structure

With a net weight of 1.4kg, the LIESA 311 is designed for easier handling during installation and removal.

For users who regularly clean large numbers of windows, a lighter machine can also reduce the effort required to move the robot between working areas.

Cleaning System

Dual-Side Water Application

The two-sided atomized spray system applies water to the cleaning area during operation. The controlled water application supports wet wiping while helping avoid excessive manual spraying.

Multiple Cleaning Paths

The 10 available cleaning modes cover different programmed movement patterns. N-pattern and Z-pattern routes provide alternative paths, while vertical, horizontal and cross-axis modes give additional movement choices.

Edge Recognition

The integrated sensor system supports edge detection, helping the robot identify the boundaries of a suitable working surface and adjust its movement accordingly.

Safety and Protection

Vertical cleaning requires more than a cleaning function alone. The Automatic Glass Cleaning Robot combines several supporting protection features.

UPS Backup Power
Maintains suction for approximately 20–30 minutes after an external power interruption.

5m Safety Rope
Provides an additional physical restraint during elevated operation.

Air-Pressure Detection
Monitors pressure conditions during use and works with the variable air-pressure system.

Edge Detection
Helps identify working-surface boundaries during automatic movement.

Low-Battery Reminder
Provides a warning when battery power is low.

These functions are intended to support safer operation, but the robot should always be used according to the manufacturer's operating instructions and the requirements of the working surface.

Application Scenarios

Residential Windows

The Automatic Glass Cleaning Robot can be used for recurring cleaning of household windows and other suitable smooth vertical glass surfaces.

High-Rise Apartments

Its automatic cleaning function and backup power design make it suitable for routine cleaning tasks on compatible residential windows.

Commercial Buildings

The robot can be used for suitable glass surfaces in offices, retail premises and other commercial properties.

Floor-to-Ceiling Windows

The square body and programmed movement paths are suitable for large smooth vertical glass surfaces where the minimum working-area requirement is met.

Glass Doors and Smooth Hard Surfaces

Compatible glass doors, stone surfaces and other smooth vertical surfaces can also be considered for routine cleaning.

Control and Intelligent Functions

Infrared Remote Control

An infrared remote controller is provided for direct operation of the robot.

Optional APP Control

APP control can be added for selected configurations, giving distributors and brands an additional control option for their target markets.

Automatic Air-Pressure Adjustment

The control system can automatically adjust air pressure according to operating conditions, working together with the pressure sensor.

Sensor-Based Edge Detection

Photoelectric and other sensor inputs support the detection of working-surface boundaries during automatic movement.

Water-Level Monitoring

The water-level sensor provides a way to monitor the available spray water and issue a low-water reminder.
