Clean exteriors. Nobody on site.
A cleaning drone that lives on your property, maps it, and washes glass, panels, walls, roofing and driveways.
Designed for
- Glass facades
- Solar panels
- Rendered walls
- Metal roofing
- Driveways
- Office towers
- Apartment blocks
- Rental homes
- Solar farms
Clean glass shouldn't need someone on a rope
Lienry is a drone that lives on the property and cleans its exterior on a schedule, with nobody working at height.
Is your building a fit?

Indicative only, from the design brief. Site requirements are still being finalised.
What changes when the drone lives on site
Five things a resident system does that a booked crew cannot.
The panels are illustrative interfaces with demo data.
From scan to report, on its own
Every clean follows the same five steps, planned on a model of your building.

Maps the building first.
Structure and dimensions, before the first clean.
- Structure and dimensions mapped
- Model built from the scan
Demo data. The building is illustrative; the software will model each property from its scan.
Built for the buildings you own
One platform on a roof, beside a house or along a solar row. Figures are design intent at concept stage, not results.
Built so nobody works at height
The safety questions owners and facilities managers raise, answered up front.

Frequently asked questions
Which surfaces does it clean?
Five kinds of exterior, each at the pressure set for it:
- Glass: facades, windows and roof glazing
- Solar panels: rooftop arrays and solar farm rows, at the pressure set for solar glass
- Walls: render and other wall finishes
- Roofing: metal roofing among them
- Driveways: on the home system, chosen in the app
The drone sets its pressure for each material before it washes.
How tall a building can it clean?
The commercial system is designed for buildings under 70 metres:
- Where it lives: a weatherproof capsule on the roof
- How it reaches the facade: on a tether fed from above, so it never carries water
- How often it looks: a re-scan every two days, which you can change
How is it kept safe?
It is designed so nobody works at height:
- Tether: water and power stay connected, so nothing is carried
- Obstacle camera: avoidance built into the drone
- Surface checks: onboard, on every pass
- Weatherproof dock: shelter between cleans
Fail-safes are still being finalised.
What happens in bad weather?
Between cleans it shelters in a weatherproof capsule or waterproof pod. Its weather limits are still being finalised.
How much water does it use?
On the roof system the tether is fed from above. Water use per clean is still being finalised.
Does it need rooftop access?
On commercial buildings it lives in a capsule on the roof. What the roof needs is still being finalised.
What permissions will it need?
We do not claim any approvals. Lienry is at concept stage, and what each site will need is still being finalised.
What does the app do?
On the home system the app runs the clean:
- Start a clean: from anywhere, with nobody booked
- Choose the areas: the driveway, the solar panels, the windows, or all three
- Follow it: each area as it is washed, then the house after
Its release is still being finalised.
How does the pilot program work?
We are preparing a pilot program for commercial buildings under 70 metres:
- Who it is for: building owners and facilities managers in Sydney
- What runs: the roof capsule, its tether and the desktop software
- The first step: a conversation about your building
Dates and terms are still being finalised. Book a pilot conversation
What will it cost?
Pricing is still being finalised. We are not publishing prices before the pilot program. Add up what outsourced cleaning costs you now
