Knock barnacles and growth off your hull, props and running gear — without hiring a diver every few weeks.

The Cavitcleaner EVO2 is a professional cavitation gun made in Europe. Held under water, it turns pressure-washer flow into a stream of collapsing micro-bubbles. The maker says it removes "any kind of encrustations, from light fouling to acorn-shells and mussels." Watch it in action.

What you need

• ✅ Tested with Home Depot's rental Mi-T-M 2,700 psi washer — available same day at most stores
• Or any pressure washer delivering about 2.6–4.0 gpm with a standard unloader/bypass valve
• A high-pressure hose (5/16" or 3/8") with a 3/8" quick-connect coupler — the plug is already on the gun
• Bigger commercial washers (3,000+ psi): turn the pressure down. The maker's limit at the gun is 160 bar (about 2,300 psi).
