AC50 High-Rise Building Facade Cleaning Drone
AC50 High-Rise Building Facade Cleaning Drone
The AC50 is our 50 m class high-pressure facade cleaning drone. It carries a spray boom and nozzle set to the working height, washes glass, metal and stone facades with a 4,000 psi (27.6 MPa) jet at 18 L/min, and runs on two 14S 33,000 mAh semi-solid batteries. The operator stays on the ground while the aircraft holds position along the wall.
It is built for building exterior walls and glass curtain walls on structures below 50 m, with a flight altitude of 50 m, a maximum ascent speed of 5 m/s and a descent speed of 3 m/s.
What the AC50 Does
The AC50 is a high pressure cleaning drone for the vertical surfaces of low and mid-rise buildings. A forward-mounted spray boom directs the jet onto the facade while the aircraft holds a fixed distance from the wall, so the wash follows the same line on every pass instead of varying from crew to crew.
- 4,000 psi nozzle pressure — lifts dust, algae film, traffic grime and hard-water staining
- 18 L/min water flow — practical coverage for elevations up to 50 m
- 50 m flight altitude, 5 m/s ascent — steady, predictable climbs up the facade
- Dual 14S 33,000 mAh semi-solid batteries — longer working windows between charges
- RTK positioning and obstacle avoidance radar — both installed as standard
- 50 m water hose with a 150 m manual pipe winder — a compact, lighter set-up than the 100 m class

Why Clean Facades with a Drone Instead of Rope Access?
Traditional window and facade cleaning depends on rope technicians, gondolas or scaffolding — each one a scheduling, safety and cost problem on a live building. A drone window cleaning system changes the set-up:
- No working at height. The operator stays on the ground, so the fall-risk exposure of the crew is removed.
- Faster mobilisation. No cradle rigging, no scaffolding permit, no facade anchor installation.
- Regular washing becomes practical. Because a wash costs less to arrange, facades can be cleaned on a schedule instead of once a year.
- Consistent coverage. A machine that repeats the same spray distance and angle does not vary from crew to crew.
Where the AC50 Is Used
Low and mid-rise commercial buildings
Office buildings, banks, clinics and retail units of three to fifteen storeys, where hiring a rope team or a gondola for a small elevation rarely makes economic sense.
Residential blocks and hotels
Apartment buildings, serviced apartments and hotels where scaffolding would disturb residents and guests, and where a compact 50 m hose set-up can be deployed from the roof or the yard.
Glass, metal and stone facades
Aluminium-framed curtain walls, glazed shopfronts, composite panels and stone cladding, cleaned with the 0°, 15°, 25° and 40° nozzle set so pressure stays on the surface rather than in the joints.
Solar panels and roofs on low buildings
Single-storey and low factory roofs, canopies and rooftop arrays where sending staff up is the main risk and the main cost.
