57 reviews for Wilks USA RX525 High Powered Pressure Washer -165 Bar / 2400 PSI

  1. wp.ball

    Bought this jet wash for patio, Patio had not been cleaned for a couple and years. Now looking great again,

    Great power, Great tools, Great value for money….

  2. Chris Lawes

    I read the online reviews re the top 2 Pressure washers avail. One was the Ryobi for £100ish. Purchased it and returned within 3 uses as was cheap plastic cr@p with very poor quality hose which constantly kept kinking/collapsing and over working the pump.
    Then bought the RX525i for half again as much and is 10 X better than the other ‘top rated’ one. For starters the Wilks has proper water pressure to remove grime. The motor is actually quieter when in use than the 3 previous jetwashes I have owned. The multiple nozzle’s cover every conceivable job. The 8 Metre hose is properly long enough to get around the wife’s big Audi 4×4, without having to pull it constantly and knock over the jet wash, which eventually always leads to jetwash damage. The product is very a sturdy, quality bit of kit, which you feel should stand the test of time which is a rare thing in this throw away world. Best tool tho’ is the roller bearing turbo nozzle which cleaned my Indian Sandstone rear patio yesterday in record time, what a brilliant ingenious design. I am a very picky individual who takes a lot of impressing and suffice to say, this is probably the best £150 i have spent in a while. Superb bit of well engineered, quality kit, for bargain money. 100% recommend.

  3. George Thomson

    I Purchased the washer for cleaning my car and patios, to replace a different brand I had had for20 years.

    Today I used it to clean my car and I found that the different attachments make light work of even the toughest dirt and I was very pleased with the final result.

    I have yet to use it on my patios but I am sure the results will be just as satisfactory.

  4. Cath

    Great machine! Tried it on the patio, fence panels, shed and raised beds. Brings them all up brilliantly. Easy to assemble and manoeuvre, and not too noisy.

  5. doreen barnes

    i purchased a power washer on amazon the RX525 i am very happy with it brillant fantastic service thanks doreen

  6. Rosemary cox

    Absolutely fantastic buy would definitely recommend 

  7. Linda Jones

    I have just purchased your RX525i Electric pressure washer. I am very impressed with this excellent item. It has all the tools you need and easy to use at an affordable price. Very professional tool

  8. colin rutherford

    fantastic bit of kit for the price and fully loaded with accessories

  9. Charles Davis

    Customer Rx525
    Great machine and excellent customer service 

  10. John Natus

    I looks a versatile bit of kit with all the tools needed for all jobs around the house. The quality seems to be better than some other well known pressure washers.

  11. Bob Hunt

    Nice solid machine, plenty of power, delivered very quickly, assembly no problem. Just done a very dirty (black patio), results are amazing. Slabs are now buff coloured again.

  12. Andrew Dyke

    This product just smashes home the power and versatility you need when buying a pressure washer for every job at home. 1st use I’ve cleaned decking, cleaner patio, cleaned cars, cleaned drive way and it was all effortless! Best money I’ve ever spent on a pressure washer. Totally recommend! 

  13. Jase Southorn

    Delighted with this purchase. Used it for the first time on the patio and it came up a treat.

  14. Cheryl Harvey

    I am super impressed with this product. The three nozzles give you a choice of water pressure. The rewi ding hose reel makes it easy to put away and store and you have plenty of hose lengh to play with. I have only cleaned my patio so far but it has removed stains that my previous jet washer had trouble removing. Arrived quickly and can’t ask for more. Thank you for a great product.

  15. Donald Harvey

    Having used the pressure washer a few times on a variety of surfaces (my car, block paving and a concrete driveway), I genuinely believe it to be worth 5 stars.
    The block paving driveway had not been cleaned for at least five years and was pretty ingrained. The patio cleaning attachment was not quite as effective as the straight pressure jet but far less messy! The whole machine got pretty messy during this job but it washed down well – there was no sign of water ingress or damage. Having got my block paving clean, I hope the patio attachment will then keep it that way with much less mess.
    The cleaning fluid bottle fitted into the machine casing is very convenient – something my previous pressure washers never had. I like the brass connections for the accessories. These look sturdy and should last many years. I haven’t tried all the different nozzles as yet. The brush and rotary brush appear to work well on the car.
    All in all I am very pleased with my purchase.

  16. Fiona Longley

    Quick delivery, easy to put together and powerful enough to make light of our large deck.

  17. robert churches

    Old Karcher broke down so bought your RX525, 165 bar. What a difference!Did back and front garden patios and driveway. Best washer I have ever used.

  18. David Lightfoot

    I had not heard of the manufacturer and I hesitated before choosing this particular machine. I need not have worried. It is so well designed and thought out and it is very easy to use. I am not a DIY expert but I had no difficulty from the start. The instructions are clear and, mercifully brief and I was delighted with the results I achieved with my first attempt at cleaning my patio. It’s the car next.

  19. Colin

    This power washer arrived today ahead of time. On getting it out of the box I noticed that the 1 of the 2 spring pins that hold the handle in place were Not engaging properly, this I feel is because the manufacturer has made a curved bump in the plastic on the right hand side looking from  the rear hence the pin does not do fully what it’s meant to do.
    I found that when trying to screw the power nozzle to the handle with the large nut it was one heck of a challenge, but I did it in the end with the help of a friend.
    Overall after power washing my driveway it came up brilliantly without any chemicals. I worked the power washer very hard and it did everything I asked from it.
    Superb machine yes I recommend it.


    Just arrived hour ago have used it already perfect piece of gear

  21. kneale Edis

    Bought this pressure washer to replace my failed Karcher one which didn’t last very long and the cost of a replacement motor effectively made it scrap.
    So far all looks good, it comes with plenty of accessories and I’v used if to clean patio and car.
    Initial impressions are good.

  22. Norman Griffin

    I just bought an electric RX525 from Amazon and having used Karcher and Hozelock before have to say this one is far better in all aspects ease of use and effectiveness primarily..

  23. David Martin

    I have bought and used this after buying two K…..r machines in recent years each of which lasted less than three outings. This is a much stronger piece of kit all round.

  24. Sue Weedon

    A brilliant pressure washer.Fantastic service.

  25. bryan durban

    used for garden and vehicles. Spot on

  26. Will Delooze

    Bought via Amazon…
    Just used this for the first time, have to say it was really easy to setup, had simple to follow instructions and delivered superb performance, brought our patio areas up a treat.
    Much better than our old Nilfisk model, having a detergent tank is really good too, and much better than siphoning detergent from a plastic bottle via a cumbersome tube.
    Used the 6m hose initially but extended it with the 8m hose and cleaned virtually all round the house whilst the pressure washer stayed next to the hose outlet and plugged in locally without the faff of plugging in extension leads and running the cold water hose out. Handy that the 6m hose winds back on the the machine as does the power cable.

  27. Michael Wade

    Purchased RX555i and so glad I did dose all I want and more the power of this unit is very and all the attachments I’ve used are easy and well made
    Michael wade

  28. Steve Starbuck

    Does the job. Plenty of power – I am having to learn to back off a bit compared to my old unit. It is easy to blow mortar out of joints if you get in too close. Like the turbo nozzle especially – really makes patio cleaning easy. The wands and connectors are all machined metal so should last.

  29. John May

    A good bit of Kit!
    Powerful and easy to use.

  30. michael Cahill

    I have used this product for 4 hours solid and it performed well. I especially like the wedge nozzle that cleaned the patio very well, mind you so did the turbo nozzle. Brick work, stone work and decking came up a treat. I look forward to doing more in the future because there is a massive difference after I had finished. some people have said the instructions are not very good but how hard is it to push one connection into another, it is simple to put together.

  31. Peter Garside

    Easy to assemble easy to use. Very powerful with a load of accessories to tackle any job. Good value for such a bundle.

  32. D L griffiths

    Was looking for a replacement for my Karcher K2 and I chanced across this. Arrived within 48 hours, well packaged and with everything as described. Came with 3 nozzles for cleaning, but the turbo lance supplied was enough to make my patio shine after years of looking scruffy.

    Powerful and versatile I would certainly recommend it

  33. lawrence

    I can’t complain about anything regarding this machine. Loads of power for heavy dirt.
    Have run out of things to clean now. Very satisfied after using this machine around the outside of the house.

  34. marc B

    Really good quality pressure washer, extremely well designed. Good long hose, gun & attachments are also of a very high standard with nice brass threads on the joints. Pressure is excellent, very please with the purchase. The shipping was also very fast!

  35. Winston Beatty

    Fastest delivery I’ve ever got real simple to set up and get going straight out the box, only done a small portion but absolutely no problem to the washer forget your Karcher this is a far better machine at half the price, unionmartltd.com will definitely return for further purchases

  36. Michelle Franks

    Excellent product, cleaned the conservatory to perfection!

  37. Gary H

    Really pleased with this product. Very powerful and mostly quality metal components which gives it a quality finish and longevity compared to the household name rivals

  38. mUNDIL t

    his product does what the advert says, was delivered ahead of time and I am thoroughly pleased with it.

  39. Sam

    Just used this for the first time today and it’s great for the price feels robust and is replacing a Karcher that only lasted 18 months you get a lot of extras with it and I feel it is great value for money,I would say it’s a bit more noisy than the Karcher but I can live with that

  40. Mr H

    All I’ll say is Americans are known for liking engines that are powerful, and this is no exception. Reassuringly heavy machine which blast the *#%€ out of anything it touches. Much better than my previous “top brand” jet washer.

  41. Ian T

    Long hose …good pressure ….metal pump head …say more?

  42. T Egan

    read the reviews on this product before deciding to purchase. I found it very easy to assemble with having to refer to the instruction booklet, but I checked them just to know I had done it correctly. Quite intuitive unless you are not very technical. It is made to a high standard and I had it working on the patio within 10 minutes.

    I was very pleased with the results and so far I can only recommend this power washer to any prospective purchaser.

  43. Donald F

    We had a Karcher before this one and it broken within a few months of slight use. Went back and fourth from the manufacturer to get fixed a few times, till finally my warranty was out of date and couldn’t get it fixed free of charge. In the end I dumped it and bought this washer. I’m finding more value for money as the build quality is better and it’s got more power, comes with more tools, hose is longer, better equipped, and over all just smashes Karcher!

  44. Bob W

    Very powerful and sturdy piece of kit.
    Far superior to my karcher, which died after only a handful of uses.
    Different nozzle selection very handy.
    Very prompt delivery.
    Would definitely recommend.

  45. Hugh

    Washer was delivered 2 days earlier than expected. Seems to work well. Agree with some of the feedback that it could do with a foot rest as it is not easy to unwind and re-wind the hose. So far, appears very effective.

  46. William Oswald

    Great piece of equipment to have,
    loads of different uses, and well worth the price, pleased with purchase.

  47. Richard

    Have went through 2 x Karcher K2 which are not good for any sunstancial run time. This unit is much more robust and fit for purpose which is cleaning up my block paving (only 30square meters) and my back patio.

    Adaptor fittings available on Ebay to use up any other Mfg. fittings such as Lance’s brushes’s ect and it delivers plenty of power, the cleaning solution fitted tank is another bonus.

  48. d preston

    After 2 x k2 kartchers 4 years we decided to look for a different make. Very pleased with this purchase, cost and power. Would recommend

  49. P M Saxton

    There are so many attachments with this product I havn’t tried them all yet , but the patio cleaner & jet nozzle have cleaned my patio up a treat . Good value for money especially when compared with the Kercher K4 & performance wise is much more powerful than my old one . It is easy to assemble & move around with the strong handle .I can’t fault it & would recommend this product .

  50. Ian

    Used this pressure washer for cleaning the drive and taking moss/algae off the wooden garage prior to repainting it. It did the job really well and came with a useful attachment to clean the garage gutter. Only issue is the instructions aren’t great but a few minutes working out what goes where and you will be sorted.

  51. Brian Paulter

    This product is beyond my expectations it is far better quality than the cheaply made Chinese products that you get for the same money and does so much more,all the extra’s are amazing and there are a lot of them I was very impressed with most of the screw fittings being brass and being able to reel the hose back into the machine after use and also storage for the electric cable,easy to work and a very powerful machine certainly the best one we have had and well worth every penny I would recommend this to anyone looking to buy a power washer and the delivery was quicker than expected,well done to the seller.

  52. Rob W

    Comprehensive package of equipment. First experience of use is very encouraging. Product specification suggested this machine should be about 40% more powerful than our previous pressure washer … and it is. Great for cleaning patios etc. Stores well because of the facility for winding up the electricity cable and the hose quite neatly. The washer is heavy but it’s on wheels and with a decent handle so that’s no problem.

  53. Paul

    Bought as a replacement for a Karcher K4 that started an internal leak. Wilkson similar price but much more power and comes with several tools. Told a couple of days for delivery arrived next day. Minor problem that the instructions are not very good. Force needed to connect hose to gun, and remove the three heads attached to the body of the machine.

    The heads are used in the gun and provides washes from pin point, to a wide spread at various pressures – very useful. Plus patio clean and brush wash!

  54. GadgetMan

    There’s a lot of parts so you might need to read the manual to make sure you set it up properly, but it didn’t take long before I could try it out.

    It’s not too big, easy to pick up and carry around, but that’s not necessary with the long pressure hose. A quick test on the patio and it was clear it will not take long to do the job, especially with the patio cleaner tool and the addition of cleaning fluid to the built in tank.

  55. W Gillian

    I ordered this unit on Monday to replace my Karcher unit which has less power than this one, it arrived on Wednesday ahead of delivery date. and it was very easy to set up and I had it working in no time,I have to say it is great value for money considering the extras that come with it and the much better pressure to shift dirt faster. I recommend this product for domestic use

  56. Gary Baldock

    Bought this pressure washer to clean my patio which was pretty dirty. This did the job quickly and effectively. Would recommend.

  57. Susie

    This is the best piece of kit that I have ever bought! Performance-wise it makes my Karcher Pressure Washer seem like a children’s toy.

    I simply cannot fault this product, I’m thrilled with it and recommend it without reservation!!!!
