    I would recommend this product in preference to a Marcher which I previously owned. It is easier to assemble is more powerful comes with better attachments included and on a cost for quality basis is far superior.

  5. Steven Naylor

    I’m very surprised by the power of this small unit but it does the job beautifully. The amount of kit you get with it you’d think it was double the price. I’m very happy with my purchase and id recommend this to all my friend its powerful super portable and great value.

  10. Pete

    Great service and product. Used it on a extremely dirty patio, brought it up a treat. Compact in size but not in power. Ideal  for the DIY,r thank you. 

  11. Peter Brownbill

    Excellent value for money pressure washer. Many attachments make all cleaning jobs much easier. There is even an attachment for cleaning under the wheel arches on the car and another for applying detergent. Brilliant value for cleaning the patio or the drive as well.


    Just purchased this Wilks USA RX510 Compact Pressure Washer – 135Bar what a fantastic pressure washer, makes cleaning the patio and car much quicker and also comes out much cleaner..

    very good lightweight, powerful enough product, would recommend.

  13. Michael Davies

    Assembly was a little tricky as the instruction/ diagram could be clearer however common sense finally saw the correct pieces going to the right places – so far cannot fault this jet washer – jet washed all my paths, patio and retaining walls and they have come up beautifully – fantastic piece of kit for the price certainly on a par with more expensive machines

  14. kurt tattersall

    Very happy with the washer and the price of the product and the quality of the product and I was very impressed with the attachments that was included it was easy to use and to set up with ease

  15. kurt tattersall

    Easy to use and good value for money

  16. Lizzie

    At first we thought it was just the accessories box that had arrived and immediately sent a message to the retailer in case the “other box” was still on the delivery van. Once opened, we soon realised that the whole system was in one box. It was a great relief and soon found out that although compact,  it certainly did a full on job on the pathway down the side of the house…….and very lightweight- no heavy lifting about while using it either.  All the dirt and green discolouration quickly disappeared after just a few minutes using only water. A great purchase. We had sent another note to the retailers after opening the box to apologise for our mistake and they got straight back to us saying if we needed any help to contact them again. Good customer service too as it had arrived much quicker than anticipated.

  17. Kane Travis

    Very quick delivery
    Very happy with the power washer , lots of accessories and very powerful for its size , just what I needed for my patio

  18. Martijn Van Renterghem

    Good bit of kit, sturdy, lots of accessories and even a karcher adapter. well happy!

  19. Ian S

    Very impressed with this jet wash!
    Laughed a little a the small size of the jet wash as was removed from box but it was easy and quick to assemble. We put it to work straight away cleaning the decking for over 3 hour it never missed a beat, great pressure an lots of different adapters to make life easy

  20. Michael Harvey

    Great little compact pressure washer, super water pressure and very good accessories.

  21. Martin Redfern

    3xcelent product and is of a quality of higher priced units and the u it arrived quicker than expected

  22. Iain Macintosh

    Great piece of kit with a good selection of attachments. Quality product. 

  23. Mark

    Delivered in good time, very good product, would recommend 

  24. Matthew Boyden

    Ordered a Wilkes RX510 pressure washer as a replacement for my aging K2, this is easily as good as the outgoing K2 and comes with some very useful additions for the surprisingly low price tag. My only negative would be the length of the hose – it is longer than the one with the K2 but still not long enough to get around a car without moving the unit around. I also found that the connection although M22 thread the same as my K2 this has a 15mm core rather than the 14mm of the K2. A quick trawl of Amazon found an adaptor to sort this for £8 so I can use the extension hoses I already have again.

    Service from Union Mart was excellent – I wouldn’t hesitate to order from them again

  25. Carol Drew

    Very impressed does the job excellently would recommend to friends

  26. Nicola

    This is a brilliant pressure washer
    And it has a lot of power for all the jobs you need to do I’ve used all attachments and there all good
    Washed my suv. Pathment drive way guttering facial boards windows patios and my tarmac drive way which had moss this product cleared and cleaned everything with little ease I would definitely recommend this item and you definitely get more then your moneys worth.

  27. Alex

    Never had a pressure washer before and done my research. For my price range this had good reviews, it came with a few accessories and PSI pressure was rated high. Accessories, not used them all, so many, but had the washer for a week now and it’s a great piece of kit. Arrived quickly too. Happy customer.

  28. Tony Wooding

    Great item – easily ordered and super fast delivery. Comes with all the added attachments you need to keep your car and garden clean. Good instruction manual and well packaged.

  29. Cabdi Nuur

    Very simple, powerful and compact , great value for money, easy to set up and light weight. I love it.

  30. Arran Thoma

    Bought this to replace a much bigger Mac Washer which was recently stolen. Very light and easy to use and is surprisingly powerful for such a compact unit. Came with an array of attachments. Excellent value for money compared to the bigger versions and well known brands.

  31. Jane Wrinch

    Couldn’t be happier. A very good piece of kit, very good price, excellent value, powerful and easy to use. 

  32. Chris Ozanne and Jeannette Turner

    We bought this for the usual purpose of cleaning our cars but also for cleaning the outside of the house prior to repainting with excellent results. All in all an excellent machine with a good range of accessories. What was really impressive was the turbo nozzle that really lives up to its name.

  33. Dave Lucas

    Good price and powerful. Especially like the adapter for Karcher tools as mine gave up on me.

  34. Mark

    Great purchase. compact machine that is a powerful washer at a good price. used to clean decking so far. lots of accessories which look good quality but not got to using yet.

  35. Suz Kennedy

    Powerful power pressure washer with lots of attachments. Wheels easy to manoeuvre.  Great for a range of jobs.

  36. Brenda Traynor

    Just purchased this. Great wee machine and great value for money. Been using it all day today all round the outside of the house. Great that it came complete with accessories.

  37. Les

    Better than other similar machines I’ve had. Light weight, easy to handle and assemble and well made. Good value for money.

  38. rees.pj

    For the price and excellent machine

  39. Alex Hodge

    Great Machine Compact, Powerful and better than any other non Commercial one I have used.
    Plenty of attachment . Arrived very quickly and I was happy with price 5 stars from me

  40. Paul Cortopassi

    I couldn’t believe how light this wee beauty was while still in the box. (My last washer was a real heavy drag). It easily cleaned my garden slabs in short order. (We live near a giant whisky bond – everything gets stained black from the “Angels’ share” which feeds a black mould on all surfaces.) It had to run for a long time but never looked as if it even thought of getting hot. A good addition to its accessories would be a non-return valve for attachment to domestic cold-water systems. Love it!

  41. Peter Messent

    My new RX510 pressure did a great job on teak garden furniture, looked like new. Comes fully loaded with various spray accessories, my next job is my stone patio where it has already cleaned my test area.

  42. Dave Bish

    I just wanted a simple jet wash and this one worked for me. A couple of simple plug together pieces, pull the trigger and away you go. For the price I was impressed with the power. Various attachments were included which I will probably never use.

  43. euan lawrence

    Packaged well and easy to assemble. Compact and light. Patio cleaner not too great at cleaning but lance has enough attachments to do a great job. Very good value for money.

  44. Paul Cooper

    I bought this as a replacement for my old pressure washer and what an excellent choice! The unit itself is light and produces a powerful jet which is easily enough for the purpose for which I want to use it for namely cleaning the patio and washing the car. I am very pleased with my purchase.

  45. Mark Turner

    Just taken delivery of my RX510 pressure washer and I’m delighted with my purchase. Easy to assemble and use. High powered and excellent value for money. Highly recommend this product 

  46. David Pritchard

    Excellent value for money. Arrived on time. Only had to attach the handle to the body and attach the hose – very simple. Used straight away and it was very effective – as effective as my old Karcher 6 which had died and needed the £169 fixed price repair. So I have saved nearly £100 for a lighter washer that is just as effective with more attachments. Powerful enough to take the surface off my tarmac drive when I got carried away!

  47. janice collins

    Very easy to assemble and use. Purchased for cleaning the car and washing down the paving in the back garden.

  48. 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

  49. 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”.

  50. 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.

  51. S Rodgers

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

  52. 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.

  53. Barry Colyer

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

  54. H Hemsley

    ordered late morning came mid morning the next day superb delivery.product seems well made and good quality, have used a few times now and i am very pleased. with regards harry.

  55. Charlenne hamill

    Really please.. husband loves it, really high pressure

  56. Molyneux Simon

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

  57. Robert Crow

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

  58. 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.

  59. 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.

  60. 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.

  61. 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 **

  62. 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

  63. 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.

  64. 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.

  65. 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.

  66. 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.

  67. 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.

  68. 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!!

  69. 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

  70. janet

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


  71. 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.

  72. Jim lavery

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

  73. 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.

  74. 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.
