Solar Panel Cleaning Robot Sweeper-140/Sweeper-140 PRO—Smart, Efficient, and Safe Robotic Solution for PV Maintenance

Sweeper-140/Sweeper-140 PRO Solar Panel Cleaning Robot is a professional-grade robotic cleaner designed specifically for photovoltaic (PV) plants and large-scale solar installations.
Built to tackle challenging environments where manual cleaning is difficult or unsafe, it delivers efficient, remote-controlled, and automated cleaning to maximize energy yield and minimize labor costs.

Sweeper-140: Standard Model
The Sweeper-140 features a 1.4-meter single brush with a built-in squeegee, combining wide coverage with powerful dust removal. Operated via remote control, it supports three adjustable speed levels (20 / 30 / 40 m/min) and comes equipped with ultrasonic sensors for obstacle detection and cruise-control for stable cleaning.

Sweeper-140 PRO: Intelligent Path Planning Model
The PRO version includes a fully autonomous route-planning system for automatic cleaning over large areas. Powered by intelligent algorithms, it performs self-navigation, cruise control, and automatic return, achieving daily cleaning coverage up to 12,000 m² with minimal manual intervention. Ideal for utility-scale installations requiring continuous, unmanned operation.

Key Features:
Intelligent Path Planning for Maximum Coverage (Option)
Automatic Traction Control — Maintains precise steering and automatically corrects deviations within 3 seconds.
Anti-Drop & Power-Off Self-Locking Systems — Automatically retreats at panel edges; prevents slipping when powered off.
Dual-Brush Option Available — Double the cleaning width for faster, more thorough results.
Long-Range Remote Controller — 30-hour battery life, 100 m control range, and real-time monitoring interface.

Note:
Safety Warning – Tilt Angle:
This product is designed for panel tilt angles below 20°.
Angles between 15–20° are considered hazardous — always secure the robot with a safety rope when operating within this range. Reduce speed near panel edges to prevent slipping or falling.
Note: The manufacturer is not responsible for any damage caused by falls or improper use.
Equipment Maintenance:
Clean the brush head after each use. When storing the device, keep the brush head facing upward or suspended to avoid deformation caused by pressure.
Water Pressure Limit:
Maximum operating water pressure: 6 MPa. Within this range, higher water flow results in better cleaning efficiency.
Waterproof Warning:
The battery and charger are not waterproof. Do not immerse or spray them with water under any circumstances.
Professional Servicing:
Maintenance and repairs should be carried out only under the guidance of qualified personnel.
