QF-50PRO · CONTACT CLEANING · 6-DOF FLIGHT

Move high-rise facade cleaning
from high-risk labor to intelligent work

QF-50Pro is a fully actuated six-degree-of-freedom aerial platform for contact-based work, integrating the aircraft, cleaning tool, visual navigation, path planning and field service.

01 — VALUE AT HEIGHT

Turn dangerous, non-standard work at height into a repeatable urban service.

Start with facade cleaning, scale from individual buildings to districts and city networks, then expand into inspection, testing and maintenance.

A / 01

High-rise glass facades

For offices, malls, premium hotels and residential towers. Contact brushing removes adhered dirt while adapting to complex facade geometry.

Core launch market

A / 02

Venues & public buildings

For convention centers, airports, hospitals, schools and civic buildings with large, recurring facade-maintenance needs.

High-volume service

A / 03

High-value contact work

Extend the platform to contact inspection, cleaning and local maintenance of tanks, chimneys, wind blades, bridges and towers.

Platform expansion

MARKET & BUSINESS MODEL

China’s high-rise facade cleaning market
RMB 20–37.5B annually

Estimate based on CTBUH building data, GIS modelling and local statistics

Customer value

Replace dangerous suspended labor with stable contact, precise execution and measurable cleaning outcomes—while reducing prolonged worker exposure to height and wind.

Growth model

Enter through cleaning services at a standard RMB 3/m², then add direct operations, city partners, equipment leasing, technology services, consumables and maintenance.

02 — ENGINEERED FOR CONTACT

Flying is only the beginning.
Stable contact is the moat.

Qingfeng engineers the coupled interaction among aircraft, cleaning tool and facade through omnidirectional control, precise force regulation, visual navigation and efficiency-optimized path planning.

Autonomous cleaning concept: vertical coverage planning, facade-boundary awareness and real-time obstacle avoidance

Six-DOF omnidirectional control

A vectored-thrust architecture overcomes conventional multirotor underactuation for centimeter-level control, wind resistance and work in any direction.

ZL 2022 1 0739442.2

Contact roller-brush system

Integrated spray and mechanical brushing improve cleanliness while reducing the water use and performance limits of pressure-only washing.

ZL 2023 2 2471260.4

Precise environment interaction

Coordinated force, attitude, path and tool control enables stable work on curved, cornered and irregular facades.

CN202510140674.X

Visual navigation & autonomous planning

The system detects facade boundaries, protrusions and structural obstacles, plans vertical full-coverage cleaning lanes, and returns to its route after autonomous avoidance.
