How the robot cleans a hull
The drone attaches to your hull by suction and crawls it in overlapping passes, the way you'd mow a lawn. Two counter-rotating brush drums lift algae, slime, and young barnacles off the surface, while an onboard pump draws the debris into a 50–180 micron filter bag. Nothing is released into the water.
Our operator watches the whole clean through the robot's HD cameras from the dock, so every square metre is verified in real time — and the footage becomes part of your report.
Safe for antifouling paint
Traditional scraping and aggressive diver cleaning wear antifouling coatings down fast. The robot's brushes are designed to remove growth without stripping paint — regular robotic cleaning actually extends the life and effectiveness of your antifouling, pushing repaints and haul-outs further apart.
How long does it take?
The robot cleans at roughly 1.5 m² per minute, so most vessels are done within an hour or two — while you stay aboard or go for lunch.
| Boat length | Average time |
|---|---|
| 40 ft (12 m) | ~45 minutes |
| 60 ft (18 m) | ~60 minutes |
| 80 ft (24 m) | ~75 minutes |
How often should you clean?
In Mediterranean water, fouling season is essentially May through October. Our recommended rhythm:
- Warm months: one clean per month — growth accelerates quickly above 20 °C.
- Cool months: one clean every three months is enough.
Most owners cover this with the annual package: four cleans for the price of three, plus a free propeller clean by our diver and priority scheduling. Read more in our hull fouling guide.
What it costs
Hull cleaning is priced at a flat £25 per square metre of hull area. A typical 10 m boat works out around £500 per clean; larger vessels over 15 metres get a tailored quote from a detailed hull assessment. Every job starts with a free on-site quote, so the price is fixed before any work begins. Try the price calculator for your boat's length.
