Watertek Honda GX390 Pressure Washer Upright Trolley

WATERTEK HONDA GX390 PRESSURE WASHER

The Watertek Honda GX390 Upright Pressure Washer is a professional petrol pressure washer designed and manufactured in the UK for demanding exterior cleaning and commercial pressure washing. Powered by the proven Honda GX390 petrol engine and built on a rugged stainless-steel trolley, it combines strong cleaning performance with a mobile, service-friendly design.

Available with either a 15 LPM / 250 bar or 21 LPM / 200 bar Mazzoni MM series pump, the machine uses a reduction gearbox to lower pump operating speed for cooler running and improved pump longevity. A return-to-tank unloader, easy-prime/frost valve, anti-vibration mounts and puncture-resistant pneumatic wheels make it a robust choice for professional operators who need a dependable mobile pressure washer.

A Mazzoni MM series pump provides reliable performance and comes with a 2-year manufacturer warranty, while a return to tank unloader valve and easy priming/frost valve enhance efficiency. This machine is field-service friendly, allowing quick repairs with just basic tools and minimizing downtime.

Designed with puncture-resistant pneumatic wheels, anti-vibration mounts, and nickel-plated pump heads, it delivers smooth operation and resilience, even in tough conditions.

With a global supply chain sourcing premium components from France, Germany, Italy, and the USA, the WATERTEK PRO provides industry-leading reliability and performance. Experience the ultimate in high-pressure cleaning efficiency—built for professionals, designed to keep you working longer.

Please note that this unit is designed to be used with a water storage tank (e.g., a wheelie bin or water tank). Garden tap pressure will not provide sufficient flow rate to meet the demands of the pump.
