Redefining Electric Pressure Washers

​The Wilks RX550 creates remarkably high pressure. In fact, this is the highest pressure electric washer on the market. When you have 262 bar / 3800 PSI pressure at your disposal, you can complete jobs in record time. The immense power is created by a quality Wilks metal pump and copper wound motor.

Designed to Outperform Any Other Brand

Wilks have created a superior design that outperforms similar lightweight pressure washers when it comes to pressure output. The air-cooled 1800 watt motor delivers the power that you need to cut down cleaning times. Many other brands are manufactured from the cheapest materials such as aluminium wound motors.

    A superb powerful washer to deal with any grime on concrete paving, walls and all general cleaning . Also brilliant for car with lots of fittings for different jobs . Love it ! Everything I hoped it would be .

    This is a fantastic machine! I’ve had other pressure washers before but none is as easy to use, and certainly nothing I have used before has so much power. Add this to a great price and delivery even earlier than expected has made me a very happy customer! Thank you.
