Wilks-USA RX510 Pressure Washer Review
Summary

The Wilks RX510 Pressure Washer has an adjustable pressure between 90 to 135 bar and is supplied with a wide variety of lances, connectors and brushes. It has a trolley design with wheels and a handle for easy transportation and storage. The Wilks RX510 has a powerful air-cooled 1800 watt motor, and is supplied with a 5 metre pressure hose.
The Wilks RX510 is a medium-level pressure washer, perfect for washing large areas and getting dirt and grease out from tight corners. The unit comes with a range of accessories, it is compact, and it is easy to wheel about.

Weight
At 8.2 Kilograms, the RX510 is lightweight enough to lift — but since it has wheels you should not need to.
Power / Bar Pressure
The Wilks RX510 has an 1800-watt copper wound brushless motor that uses around 8 amps. This motor is dependable, robust, and pressurizes water to 135-bar.
Hose Flow Rate

The Wilks RX510 has an average flow rate of 360 litres per hour or 60 litres per minute. With a peak flow rate of 450 litres per hour, the RX510 pumps enough water to wash up to 30 square metres per hour.
Noise
At less than 80 decibels, the Wilks RX510 is quieter than many other comparable pressure washers with the same power. This noise reduction is, in part, due to the brushless motor.
Accessories and Use
Along with the pressure washer, gun, and lance the kit also comes with:
- A rotary brush for cleaning cars and a larger patio brush.
- A detergent bottle that fits into the unit.
- An adapter to fit Kärcher attachments.
- Various nozzles.
- A spray gun and extension lance.
- A garden hose attachment
- A 5-metre pressure hose.
Practicalities and Design
The Wilks RX510 will connect to the mains water supply or run from a static water supply. Perfect for those that are planning to run the washer off a generator and a water tank at a remote location.
There is a lock button for the gun — to let your fingers rest when cleaning for long periods. The washer also has wheels and an extended handle, for ease of movement when working on large surface areas.

Should You Buy This Model?


You would not want to use this on large swathes of concrete, but for most medium-sized vehicles and patios, it is more than adequate. The adapters are plentiful, and the Wilks RX510 offers a lot of cleaning power in hand.
Conclusion
This machine is well-built, with a robust brushless motor and a well-thought-out design to make it compact and practical. Some extensions, such as the patio brush, makes little difference over using a regular lance. But there is a lot of flexibility in a machine that can run from a static water supply as well as from the mains. The Kärcher to Wilks adaptor is a great feature if you are switching brands as it allows you to use the lances and attachments from your old pressure washer, if required.

Hi John, I had exactly the same issue. I will be doing a video shortly of this pressure washer, so hopefully that will help. To insert the nozzle you need to pull back on the ring at the end of the lance, then push the nozzle in releasing the ring and locking it into place. Hope this helps.
