Clean Higher, Safer, and Faster | Without Sending Workers Up the Wall

Easy for beginners. Built for experts. AI-assisted mapping, automated routing, and intelligent obstacle avoidance — so the drone handles the flying while you handle the work.

Forget the old school DJI airframes with bolt-on nozzles. The HoverWasher HW150 is engineered for wall cleaning from the ground up.

The HoverWasher HW150 is a next-generation multi-functional washing UAV engineered to replace dangerous, slow, and expensive manual high-altitude cleaning. Built for building facades, photovoltaic arrays, wind turbines, power grids, insulator strings, and highway signage, the HW150 brings 30 MPa rated (35 MPa peak) high-pressure cleaning to the air — covering up to 1,000 m² per hour while keeping your crew safely on the ground.

If your team still relies on rope-access "spidermen," cradles, or scaffolding to clean exterior walls and solar panels, the HW150 is the upgrade you've been waiting for: lower risk, lower cost, higher throughput, and dramatically better coverage of complex architectural geometry.

Why Choose the HoverWasher HW150 Cleaning Drone?

Manual overhead cleaning is plagued by four core problems — and the HW150 solves all of them:

• Operational risk — Scaffolding, harnesses, and cradles expose workers to fall hazards, especially in poor weather.
• Slow cleaning speed — Hand-washing large facades takes days and rarely delivers consistent results.
• Poor flexibility — Fixed-track and rail-mounted automated systems only cover a narrow set of building geometries.
• High total cost — Whether you're paying for labor or amortizing fixed cleaning rigs, traditional methods are expensive to deploy and maintain.

The HoverWasher HW150 replaces all of the above with a single portable, modular, remotely-piloted cleaning platform.

Key Features at a Glance

High-Efficiency Aerial Pressure Washing

• 1,000 m²/h light-cleaning throughput (≈17 m²/min)
• 30 MPa rated / 35 MPa peak water pressure for stubborn stains, mold, and biological buildup
• 15 L/min spray flow rate with 100 m supply hose for tethered, uninterrupted operation
• 1,500 mm spray pipe keeps the airframe a safe distance from the cleaning surface

Modular Mounts & Four Interchangeable Nozzles

The HW150 ships with two mount options and four quick-swap nozzles, so a single drone covers virtually every cleaning task:

Mount options:

• Fixed nozzle mount — 1,500 mm extension keeps the fuselage clear of walls for safe, reliable operation.
• Oscillating nozzle mount — 45° swing range with operator-adjustable swing speed, perfect for matching different soil levels.

Nozzle angles (tool-free swap):

• 0° — High-pressure jet for crevices, seams, and stubborn stains
• 15° — Fan jet for rapid stain rinsing
• 25° — Wide fan for sand, soil, and dust removal at high efficiency
• 40° — Broad fan for rinsing large surfaces after detergent application

Intelligent Route Planning (HW150 v2.0)

Set the route once and let the drone fly itself. The HW150's autonomous flight planning delivers:

• Comprehensive coverage — Pre-defined facade paths eliminate blind spots and missed sections.
• High automation — Plan flights at the ground control station, then watch the drone execute without manual stick input.
• Centimeter-level precision — Dual-RTK positioning maintains a stable attitude and exact spacing from the wall.
• Remote operation — The pilot stays in a safe location while the drone handles the dangerous airspace.

Built-in Safety Systems

• Dual RTK centimeter-level high-precision positioning
• Front-facing radar obstacle avoidance with real-time environmental sensing
• Real-time ranging keeps the nozzle 2–3 meters from the target surface
• Zero personnel at height — eliminates the single biggest risk factor in commercial cleaning

Rapid Deployment

• 1-minute quick-release setup
• Folding airframe for easy transport and storage
• Tethered water supply removes the volume limit imposed by onboard tanks

Application Scenarios

The HoverWasher HW150 is purpose-built for multi-scenario aerial cleaning:

• Building Facade Cleaning — Curtain walls, glass towers, metal cladding, mixed-material exteriors
• Photovoltaic / Solar Panel Cleaning — Rooftop arrays, ground-mount farms, and panels installed over fish ponds or water bodies
• Wind Turbine Blade Cleaning — Reach blade surfaces without rope access
• Power Grid & Insulator Cleaning — Towers, insulator strings, transmission infrastructure
• Highway Sign Cleaning — Overhead gantries and signage along expressways

Real-World Case Studies

Case 1 — Building Facade Maintenance, Dongguan

A 60-meter, 18-story high-end building in Dongguan suffered persistent mold and dirt buildup on its exterior walls due to Guangdong's frequent rainy weather. The complex high-floor structure made manual cleaning slow, dangerous, and prohibitively expensive (10+ workers, daily wages of 300–500 CNY each). After deploying the HoverWasher HW150:

• Personnel were removed from height entirely
• Long-term labor and maintenance costs dropped substantially
• Cleaning crews maintained a safe 2–3 m nozzle-to-surface distance with real-time ranging
• Full-facade cleaning time was cut significantly thanks to 1,000 m²/h throughput
• High-pressure jets, paired with cleaning agents, removed stains immediately

Case 2 — Floating Photovoltaic Cleaning, Huizhou

Photovoltaic arrays installed over fish ponds in southern China accumulate algae and biological growth in hot, humid conditions. Manual cleaning over open water carries serious drowning and electrical-shock risks. The HW150 enabled large-area, no-water-access cleaning — preserving panel power-generation efficiency without putting workers on the water.

Case 3 — Curtain Wall Maintenance, Shenzhen

A commercial building near a Shenzhen industrial park accumulated heavy dust on its curtain wall. In 2024, the HW150 was selected as the maintenance solution and delivered safe, efficient, low-cost cleaning that restored the building's high-end appearance.

Case 4 — Metal Facade Cleaning, Shenzhen Park

A 5-story iconic building in a Shenzhen park, with a faceted metal exterior, suffered mold and dirt staining from local rainy weather. In September 2024, the HW150 cleaning drone replaced traditional methods, providing a safe and economical maintenance solution for the property.

Frequently Asked Questions

What is the HoverWasher HW150 cleaning drone used for?

The HW150 is a multi-functional washing UAV designed for high-altitude aerial cleaning of building facades, photovoltaic panels, wind turbines, power grid towers, insulator strings, and highway signs. It uses high-pressure water (up to 35 MPa) to remove dust, mold, soot, sand, and biological growth from surfaces that are dangerous, slow, or impossible to clean manually.

How fast can the HoverWasher HW150 clean a facade?

The HW150 delivers up to 1,000 m² per hour in light-cleaning mode (about 17 m² per minute) and 500 m² per hour for deep cleaning of heavily soiled surfaces.

Is the HoverWasher HW150 safer than rope-access window cleaning?

Yes. The HW150 keeps the pilot at a safe ground location while the drone handles all overhead work. Combined with dual-RTK positioning and front-facing radar obstacle avoidance, it eliminates the fall risks associated with scaffolding, cradles, and rope-access "spiderman" methods.

Can the HoverWasher HW150 clean solar panels installed over water?

Yes. The HW150 is widely used for floating photovoltaic and over-water solar arrays — for example panels installed above fish ponds — where manual cleaning carries drowning and electrical-shock risks.

How does the HW150 handle different types of dirt?

The drone ships with four interchangeable nozzles (0°, 15°, 25°, 40°) and supports fixed or oscillating mounts. Operators select the right nozzle/mount combination for each task: tight 0° jets for stubborn stains and crevices, wide 40° fans for detergent rinsing, and everything in between.

How long does it take to deploy the HoverWasher HW150?

The HW150 features a folding airframe and quick-release mount system, allowing deployment in approximately one minute once on site.

What's the maximum wind speed the HW150 can operate in?

The HW150 is rated for operation in wind speeds up to 12 m/s, with a maximum horizontal flight speed of 15 m/s.

Does the HoverWasher HW150 support autonomous flight?

Yes. Version 2.0 introduces intelligent route planning through the ground control station. Operators define the facade path, spacing, and stand-off distance, and the drone flies the route autonomously with RTK-grade precision — ensuring full coverage without manual stick input.
