The Highest Pressure Output Electric Washer

Redefining Electric Pressure Washers

The Wilks RX550i 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 heavyweight pressure washers when it comes to pressure output. The air-cooled 3000 watt motor delivers the power you need to cut down cleaning times. Many other brands are manufactured from the cheapest materials such as aluminium wound motors. Wilks only use quality copper wound brush-less motors to offer unparalleled reliability.

Quality Brand, Fantastic Reputation

Excellent quality & price
Very happy with this pressure washer. The different nozzles are a great idea allowing gentle cleaning of our patio furniture to extremely pressure required to clean car engine cases prior to rebuilding. I would definitely recommend this to users from households to businesses. Read more

Excellent Pressure Washer
The product is excellent and comes with a lot of additional items to help with all the pressure washing jobs you will encounter. Excellent long hose is really useful as can reach to the top of my garden but leave the unit next to the water supply at the bottom of the garden. I had a Karcher for many years but this is better and you don't have to pay for additional equipment as it all comes in one box. Read more

Worthy replacement for Karcher
Looking to replace a large Karcher, I wanted a pressure washer that was more robust and easy to use. This fits the bill. Heavier than the Karcher, it is however much easier to handle and and move around. The connectors, being quality screw ones, may take a few more seconds to use but are very secure (and less force required to couple and uncouple them). There is plenty of power, a choice of jets, and the extra hose is brilliant for cleaning my york stone paths, so I don't have to move the machine all the time. My only reservation is that with an integral tank it is difficult to change the type of detergent, but that is a small niggle. I have used it about four times now for fairly large jobs and been very satisfied Read more

Strong & well Built
Used this product for a couple of hours and found it easy to assemble and use. As far as I understand its the maximum pressure is only the initial pressure when you first squeeze the trigger then it reverts to 155, saying that it cleaned stubborn marks with ease and was much more powerful than my k4.Going to make the job a lot quicker and easier.

Fantastic and so much equipment
I was sceptical when I purchased this power was her but when it arrived o was super impressed!!! I cannot believe the amount of extra equipment you get for the price. The compatible Karcher equipment will cost you a good chunk of money on top of the price of the machine... not with the Wilks. The machine it’s self is fantastically powerful and although the pressure isn’t adjustable, you have plenty of choice with the quick release nozzles which varies the stream pattern and as such gives the impression of less pressure. Been using this machine for about a month now, almost on a daily basis and cannot find a fault. The whole kit and caboodle just oozes quality. Read more

Usually I do not do reviewing, but now I have to! This is a replacement washer because my Karcher K7 been stolen :( This is almost a half of price than K7, comes with more attachment, 3 times longer hose, 5 different nozzles and My opinion is the max pressure stronger, Ok not fancy as a K7 , No display and button control, No turning nozzle changes, But who cares, I just used once until now but very satisfied, hopefully it gonna last for a while Highly recommend! Thanks Read more
