  1. Anthony Knipe

    Wow. Put my old washer to shame. Even volunteered to clean the neighbours patio I was enjoying it that much.

  2. Stephen Wain

    Excellent product, very well made and all accessories fit on board.
    Very fast delivery

  3. Nidge Gladstone (verified owner)

    Wow, impressed with the RX545, its powerful and compact having a hose real and storage for all of the attachments. This thing has more toys than an Anne Summers party. After 4 Karchers I gave up and wanted a change, I purchased from Union Mart as I have one of their generators and they customer service and warranty an second to none

  4. Andy Cooke

    Fantastic product, really well built. Clearly a lot of thought has gone into the design. The nozzles are a great idea.

  5. lynn harris

    i recently purchased this pressure washer ,iam delighted with it and have cleaned my block paving the results were fantastic ,i would recommend this pressure washer .

  6. Charlotte

    Great product , very powerful, Quick delivery

  7. Paul Tupper

    Excellent product, I bought the RX 545i from Amazon. It arrived today, the day before expected.
    I have been using the machine to clean a wooden garden table that looked like it was ready for the dump, The RX545 made it look nearly new again.
    Certainly I recommened this product over other pressure washers on the market…
    Thank you Wilks

  8. Keith Irving

    Top machine and service from Unionmart. Quick delivery and kept informed. Looks good and feels good. Seems like very good value all things considered.

  9. Jane Dale

    Really powerful pressure washer with useful attachments. 25 years of patio grime was washed away very quickly and easily.

  10. Chris Hart

    Arrived yesterday. What a brilliant bit of kit. I wanted to remove some paint from a brick wall. My old Karcher didnt touch it but this machine made it easy. Cannot fault it so far. The variety of nozzles and extras is superb. You will not want for anything else

  11. Michael Murphy

    I bought a Wilks RX 545i. What a machine! The additional brushes amongst the accessories make it exceptional value for money. It is easy to use and powerful. My previous washer had become ‘tired’ and was not cleaning well. This one has made the job of cleaning much faster, leaving my patio/garden walls/driveway like brand new. It really has been remarkable. I would definitely recommend this washer to any one.

  12. Stuart Hollamby

    I purchased this pressure washer to replace my Karcher. It has certainly lived up to the great reviews it has received.
    This is a fantastic product at a great price. Delivery was very prompt. I had a query re slight damage to the patio head cleaner which was resolved instantly without any quibble, a replacement arrived in the post within a few days.
    The customer service is very impressive.
    I have used the pressure washer serval times. It has plenty of power and the interchangeable nozzles make it really useful for a variety of jobs around the home. The motor does not have a high pitched whine unlike other pressure washers which can be very annoying during prolonged use.
    I would definitely recommend this product and supplier to any interested parties.

  13. Terry Martin

    Just purchased the 545 washer and cleaned my patio. easy. A great washer and would recommend this to anyone.
    5 Star rating no problem.

  14. Terry Martin

    Just brought the washer and it works fine. Cleaned the front patio clean as a whistle. 

    I would recommend this product.

  15. Nigel Green

    Very prompt delivery, well packed and easy to assemble just a couple of parts – worked well on first trial, far more powerful than my previous raging bosch. Good customer service 

  16. Russell Barrowclough

  18. Frank

    prompt delivery, good machine with a wide selection of accessories
    very pleased 🙂

  19. Pat Stansbridge

    Purchased the RX545 pressure washer and I am delighted with the performance of this piece of kit. Way out performs other pressure washers I have purchased to only be disappointed in both in performance and reliability. No cutting out on prolonged use, a well engineered, robust, and quality product. My Yorkshire stone paving are now back to as fitted after a number of years neglecting them. 
    Customer service second to none also.

  20. sandra betts

    Brilliant machine cleaned our patio first time and it was heavily stained and slippery.

  21. Brian Mckie

    First off the 210 Bar that people say is bad advertising , if you read the description on the item page it say’s the working pressure 138 bar ” 3050 PSI / 210 Bar Max Pressure
    2000 PSI / 138 Bar Continuous Pressure ” taken from Amazons site . so read before you purchase and don’t complain after cause you didn’t do your homework.
    Ok Rant over on to the Pressure washer .
    I read loads if not all the reviews on here and on their own web site and looking at Blaupunkt PW7200i and Karcher K4 and K5. the pressure washer I have before ordering this was a very old Karcher K2.36 I got free with some car insurance many years ago. I thought it was time for a change. I never thought the pressure was that strong in the Karcher but that was all I had. but cleaning my car meant picking the washer up and walking around the car to get all around it . first the wheels then the car . the last time I used it the XHoze snapped off at the plastic connection when I went to move it.
    So I was looking for a washer with a longer reach 8 meter or so and this one comes with 8meters and an extendable 10meter so I thought YES . So glad I did I didn’t need the 10mtr extension hose but think I will use it next time.
    I read the instruction book it is so easy to work out what does what the nozzles different colours the book tells you what they are fore I used the white one which and general cleaning the Blue is to apply soap . Not tried the others but as the white one did the job why change for a stronger jet ?. I did only get this for cleaning my car so cant say how good it would be on slabs etc.
    as for foam cannons there is a fitment for the patio cleaner that would let you connect a standard fitting to the gun 🙂 just means you will need more space as it will add 400 mm to the gun .

    I did what the book said turn on the water press the trigger to get the air out then powered it up .( connect the gun before the water and there isn’t anything to stop the water from flowing straight through the unit , and connecting it after just gets you very wet )
    I will play with the different spray nozzles next time just to see but cant see me using them for much unless the other half finds out I can use it to clean the patio lol

    I am very happy with Wilks-USA RX545

  22. Alistair Henig

    Decent product,however i have not fully used it yet,plenty of little extras that make life a little easier. However the rotary accessory is not quite giving the results expected, might be me expecting too much .

  23. P McBride

    A very good machine. it has mostly metal threaded connections and some sturdy plastic type fittings that a locked into position. It has plenty power and a range of jets for difficult areas and standard washing. All the extras is a huge bonus. if the manual supplied is short on some detaisl, a quick search on-line will find a more comprehensive one.

  24. Matthew Percival

    This is a fantastic product! My patio and paths around the house were covered in green algae that has been there for some years! This pressure washer has removed it easily and quickly to the point it looks like the patio has just been laid. Extremely powerful machine with a variety of jets and attachments for a wide variety of jobs. Once I started I just wanted to keep on going!

    PS. Great delivery schedule – was with me within 2 days via courier.

  25. Terry Foxx

    I bought this as a replacement for an ageing Karcher which had done its best over many years. I was looking for something similar and came across this brand which was unfamiliar but a good price. Reviews seemed positive so we took a chance and ordered it. It arrived very quickly and despite the minimal instructions I managed to put it together without too much difficulty. I have only been using it for less than a month but I am already impressed with the results – my patio was easily cleaned of the dirt which had accumulated over the winter. The range of attachments is very good.

  26. Meng J

    It is easy to assemble and operate. It does all the requirement that I want. Highly recommended.

  27. Graham Finder

    I bought this power jet after reading reviews about. It has lived up to the reviews and I am delighted with it. I have done three quite big cleans, one drive and one patio using the most powerful jet. My daughter used to clean her patio.

  28. Karen A

    Found the washer to be of good build and a quality product. Lots of different accessories and different types of jets.

    Will recommend this product too all my family and friends

  29. Claudio

    I bought as a replacement for an old Karcher and have found this to be much better – much more robust and powerful enough for any job. Have so far cleaned patio, conservatory roof and car with outstanding results each time. The attachments are excellent and easy to put together.

  30. MacGowan

    Works well. Easy to use.Not used all the attachments yet, the lance does most things. Would be useful if there were more examples of which nozzle and which attachment to use for different cleaning jobs.

  31. Lynne Parker

    Very powerful and east to use. I particularly like the interchangeable nozzles.

  32. Simon p

    This is so much better than my Karcher. It is better in every way. If you are thinking of a purchase then you are making a good choice.

  33. Stuart Hay

    Just recieved this, have used it to clean the car using a snowfoam attachment I bought seperately and it worked great, I have also started cleaning paths and patio with it and it is handling tasks with ease and has very good pressure. Extension hose is great for patio. So far very impressed.

  34. Andrew Clarke

    Excellent product has everything you need very powerful

  35. R.P.H

    It’s lighter than UK equivalent washers and the use of different nozzles rather than adjusting the lance is simple and effective. I’ve found the drain/guttering lance excellent for cleaning under the car and wheel arches and it seems quieter than UK models.

  36. Vasile

    I found the product very useful, and not only for car washing you can also clean the pavement, clean the walls from outside, etc.

  37. Geraint Skyrme

    The product was delivered early tried the products straight from the box everything worked perfectly very happy with it including all the different jets yes I would recommend this product to anybody

  38. JOHN

    Over the moon with this!

    It has four different types of spray nozzles very quick and easily interchangeable, the hose is plenty long enough to not have to drag the machine around and is on a reel so easily wound back in.
    It also has 2 car cleaning attachments/brushes a patio cleaner attachment and a curved metal attachment to do underneath car and wheel archers. I Have previously owned 2 karchers that lasted about 2 years each this seems far superior to those.

  39. Nick Wolstencroft

    This machine broke on it’s third use, obviously it does not live up to i’ts claim of “resilient reliability” I would not buy one of these products ever again.

  40. Dennis Murray

    Product was very easy to put together. Easy instructions. Perfect for most jobs. Can’t wait to get started. Great price for a quality product.

  41. Peter P

    Love the long lead, interchangeable heads, and ability to tidy hose real and electric cable with ease.
    Unsure if I notice a remarkable difference in pressure compared to my older K2 karcher.
    Only downside was no snow foam bottle. Which I purchased separately.

    Decent buy though.

  42. Monty

    Seems a sturdy unit.. not sure how to get the telescopic handle up.. any ideas ??

  43. James MCMILLAN

    Very good washer with an excellent build quality and several really good accessories. The unit is sturdy and easily moved around. It was easy to assemble and so far the power and variety of the jets are very impressive. Easily the best power washer I have owned in the last 10 years.

  44. Donna

    Bought to clean patio and block paved drive. Have since cleaned garden furniture and garage doors. Will move on to cleaning the cars next. Great investment!

  45. J Baker

    I bought this jet washer to clean my patio but it also does decking and fencing. It can strip paint if you are not careful with the settings! I can also use it to clean my car, my bike and my camper-van. A good value product, delivered right on time, as described and in very sturdy packaging. Excellent!

  46. René DAndoy

    très bonne machine j’en ai essayé trois avant l’achat de celui ci sans comparaison au point de vue efficacité très bonne idée de changer les gicleurs plutôt que de tourner le manche car on use qu’un seul gicleur

  47. Trevor R Bevan

    I received my Wilks-USA RX545i today and it is working fine.
    The Pressure Washer came in a strong and sturdy tall box with so many accessories, each with its own special purpose. DPD delivered a day early which was much appreciated. Packing was perfect and all items were included and the machine was in pristine condition. The pleasant surprise, upon opening the box, was to find a Voucher for a £20.00 Refund by Union Mart UK which you get after completing a Google Review.

    Assembling the Power Washer was easy but it is essential to first read the Operator Manual from cover to cover. Incidentally, the Operator Manual, written specifically for the Wilks-USA RX545i, was so clear and well written, with illustrations to every important feature. There are so many accessories it’s a good idea to just slowly try each one out to get used to things. I can’t wait to use the Patio Scrubber, a large circular device with two rotating jets and a brush surrounding the circumference. The Gutter cleaning Power Wash will be a great opportunity to clear the gutter of the autumn leaves which gathered from last November.

    I’d been awaiting this delivery because my old Karcher had finally given up the Ghost, after 15 years. So I needed to Power Wash my Motorbike after its Winter Hibernation. What a delight to use it on my Bike which now looks brand new after nearly 10 years of use. The hand Brush is ideal for that and Car Cleaning too. The Shampoo flows nicely through the Brush. The fixed Shampoo Reservoir is a great improvement on the Karcher, and produces a good flow of Shampoo simply by adjusting the flow rate with the big dial.

    I am so glad I chose this Wilks-USA RX545i, Very High Powered Pressure Washer.

  48. Susan Gray

    Excellent product. Does what it says on the box. Very pleased all round

  49. Paul Bowman

    Really good value for money.
