Portable And Easy To Use

The Wilks RX510 creates high pressure from a compact and durable unit. On-board storage is complemented with travel wheels and handle to allow for easy movement. This lightweight 8.2kg unit produces a very respectable 1950 PSI from a quality Wilks metal pump. This provides consistent, reliable pressure.

Designed to Outperform Other Pressure Washers

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. Wilks only use quality copper wound brush-less motors to offer unparalleled reliability.

All of our washers are manufactured by Wilks-USA, one of the fastest growing washer brands in the world. We offer a 1 year warranty on all of our machines, as well as UK based technicians and an expert technical customer service team on hand to assist with any queries.

  1. Amaline Targett

    Well packed and easy to assemble, used straight away and was pleasantly surprised, it was really quite powerful.
    Nice and handy for non commercial jobs

  2. AST

    Excellent value for money, especially as it comes with all attachments and others charge extra. Cleaned the car really well, the soap bottle is really useful. The manual is a bit light (silent) on what each attachment does / can be used for but connecting them and trying them out is just as good, and more fun than reading a manual 🙂 .

    Also used it to clean out the wheelie bin (green garden waste) and it shifted everything that had accumulated and stuck to the bottom. At £7 a month to subscribe to the bin cleaning service, this will pay for itself quickly, add the £10 that Tesco charge for a jet wash and in three months this becomes a “freebee”.

  3. Julie Bell

    very pleased with this pressure washer.very light to move around and easily removes winter grime on my patio. Would recommend this product.

  4. S Rodgers

    Handy tool for car and driveway. Works well and is good value for money

  5. Oli

    Good product at a good price. Packaging was good, the washer was easy to assemble and use. Cleaned the car and blasted some dead ivy remains off a wall.

  6. Barry Colyer

    Good all round performance if you haven’t an outside tap you can even use a large bucket

  7. H Hemsley

  9. Molyneux Simon

    Cannot believe how brilliant this little pressure washer is,it has great pressure,well worth the money.

  10. Robert Crow

    Only used this two times now. it works well. had no problems in setting it up.

  11. Colchester

    Works well,lots of accessories,unfortunately one accessory does not seem to go anywhere nevertheless all the others are useful so not bothered about this one. The only little niggle is the manual does not elaborate what each accessory is used for.

  12. Tanroy

    This machine is just what the doctor orders as far as I am concerned. I have tried it on several applications and all have been just what I needed. I would recommend this Pressure washer to anyone.

  13. C G F

    Compact and easy to store. Accessories plentiful. Easy to assemble and once assembled ready to go. Pressure is good for the size & price.

  14. Kernell Williams

    This power washer is replacing one that I have used for some time with difficulties in that it was very heavy and complicated this machine is totally different in a very good way it is soooo much lighter and easier to use I have only had it a few days but have used it on concrete steps ,stone patio and the car and it has done a brilliant job on all of these tasks now it does not feel like a chore to get it out and ready to use . My advice to anyone looking to get a new power washer is ** get this one **

  15. Billiam Smith

    Simple to assemble, very easy to use, really low price, made of very durable materials.
    Instructions very easy to follow, (all in English as well) took less than 1/2 hour from opening the box to using it safely.

    Very ridged packaging, all items present.

    This wonderful machine is the best pressure washer I’ve ever purchased,
    100% satisfied both it.

    Thank you

  16. Nick K

    Bought this to replace a Karcher K2 which gave up the ghost. The price of the spares made it uneconomic to repair. Did some research and this came out with some very good reviews.

    It’s a bit more powerful than my old Karcher and very well made.Used it on my path and teak garden bench this afternoon and delighted with the results.

  17. Puddleduck

    Bought as a gift for my son, the Electric Pressure Washer was easy to assemble and easy to use, doing a great job washing the car.

    There are many nozzles and choice of brushes to use, for washing the car and wheels etc.

    He is very pleased with it.

  18. John B Higgins

    Item arrived earlier than expected, well packaged and simple to get going with minimal assembly.
    It’s smaller than expected but packs a mighty punch.

    I like the fact that I can use my old Kärcher tools using the enclosed adapter.

    So far so good.

  19. Bingsley

    Arrived earlier than specified. Easy to put together and is robustly built without being too heavy. Easy to operate and works well. Very pleased with the purchase.

  20. Lewis

    Great power washer, first time use today but motor seems far more powerful than the equivalent brand leader (starts with a K) I’ve had 2 K2 machines in 4 years and quite frankly they are poor, both of them packing up with not particular heavy use.

    This Wilks washer seems to be better made and as I say more powerful. I guess time will tell, but happy at the moment.

  21. M. Daniels

    Good product with lots of handy attachements that other products have as additinal extra. I used the bottle attachement yesterday to ‘foam’ my car before washing which was a dream to use, and better than paying £20 a pop for a car wash!!

  22. Jake

    This is well built, nice long hose, brilliant amount of accesories. Very well packaged and a fast delivery very pleased much more powerfull than my last generic cleaner

  23. janet

    Amazing jet wash.. really powerful, extra attachement brushes.. really would recommend. I went by the reviews when purchasing and am pleased I did.


  24. Jana

    Lovely. This is a light in weight pressure washer with cables and hoses long enough to clean a 35′ patio from an indoor power socket. The pressure per minute is suitable to clean off a couple of year’s moss and ingrained dirt. The instruction book does not describe uses for the attachments so I assumed the circular brush was a patio cleaning brush. It isn’t.

    The bonus is having a few attachments as well as one that will taking Karcher fittings you may have! There is a child lock on the trigger so children can’t just point and “shoot”! I am pleased that such a small and light washer is capable of such a good job, no doubt it will come in handy for cleaning my car and conservatory windows as well. Should you have questions the company happily answers them by phone or email.

  25. Jim lavery

    I would recommend this product, does a great job and it’s value for money . Fast delivery too.

  26. Robert Rivett

    The washer was delivered before estimated date, well packaged. All components clearly marked. When tested it seemed to operate as per description. So far it seems well worth the money.

  27. Deborah Exley

    Product is fantastic both in price & ability to do the job required. Fast, easy transaction & great customer service from Union Mart UK. Completely satisfied with whole aspect from purchase to delivery.
