A high-performance oval cleaner designed by Duojing with stronger suction, smarter path planning, and a quieter motor. Designed to be safely used on framed glass, tiles, mirrors and smooth walls.
3000 Pa vacuum suction holds the C03 firmly to vertical glass — tested to carry 25.2 kg. A 20-minute UPS backup, a safety rope, and anti-fall sensors protect every unit, even in a power outage.
High-rise exterior glass, indoor bathroom tiles, sun-room windows, kitchen countertops — the C03 handles them all without scratching. One product in your catalog, four end-user segments.
A 15 μm micron-fog nozzle sprays a C-shaped mist, then the dual microfiber wheels wipe the area — no streaks, no dry spots. MEMS edge detection and a zigzag AI path cover the whole window without manual steering.
A complete quality-controlled workflow across our 12,000 m² facility in Zhengzhou.
In-house ID and structural design teams define every C03 outline, color and material.
Skilled workers assemble every C03 on a clean, organized production floor.
Motors, sensors, wheels and power modules are mounted and aligned by trained technicians.
Every unit is run-tested on glass for suction, movement, safety and spray before packing.
Branded color boxes stacked on warehouse shelves — ready for immediate dispatch.
Pallets loaded onto delivery trucks, tracked all the way to your warehouse.
