  1. Ross Nelson

    Delivered in 3 days two clips missing from the handle however contacted union mart and despatched them 1st class so great service as for the pressure washer it is a beast perfect for large drives and patios and despite some other reviews 10mins puts it together. Highly recommend. 

  2. ian evans

    Brilliant pressure washer delivered promptly, easy to use. Very effective. definitely worth the money.

  3. William Allen

    This pressure washer is such an improvement on other washers I’ve worn out .Easy to assemble & start (remember to turn off water & release pressure in lance) & this machine is ready to impress even the most reticent in double quick time. I recommend this machine above the opposition for performance & price .

  4. Bartosz Wojciechowski

    When I worked as a valeter we have had a great pressure washers available for our work. Later I have started to work as a hgv driver and I have a comparison of pressure washers power as we used them for washing fleet. I was looking for sth that generates satisfactory pressure for my around home works, flags cleaning, car washing, blasting etc.,
    I have used some karchers with around 130 bar generated pressure and was not satisfied. This one is something I EXACTLY was looking for. It starts first time, it’s loud but pressure is just as powerful as I needed. If somebody is looking for a really good washer, this is the one. Price is just right. Especially for what it offers. Look no further, just buy IT!

  5. john.e.warman

    After being a Karcher man for a great many years I became somewhat disillusioned when my last one ceased working of late after having been returned to the factory for repairs and bits of plastic dropping off etc. Much searching online led me over and again to Wilks USA. I read so many reviews about them, mainly good. I phoned up Wilks USA head office and spoke options through with a chap called Henry, most informed fellow for sure. Long story short I opted for the TX750i. WOW am I glad I did. The absolute power of this beast compared to Karchers is off the scale. It will strip paint so you have been warned. You must use the right attachment for the job in hand. Cleaning the drive was an absolute breeze, a doddle infact. To address the negative reviews I read…unable to attach the pressure hose inside the drum…hmmm…if you look you will see the ends of the drum are attached by 6 screws, undue them, split the drum, attach hose, re-insert screws problem solved, simple. Leaks everywhere…hmmm…as with all high pressure equipment use plenty of ptfe tape (provided) and snug up all threads firmly, simple. Engine doesn’t start…hmmm…follow instructions to the letter, top up both sides of engine with oil as per diagram and she starts first time every single time, simple. Water on last after starting, water off last after stopping…it spells it out in the book! I would absolutely recommend this beast of a pressure washer to anyone, I really would. I haven’t even mentioned delivery yet…here within hours, amazing.

    Wills TX750i – Very Impressive

    After much research I decided to buy the Wilks TX750i and I’m delighted with it. Ordered and delivered in 3 days the machine arrived in a very substantial box which in some way was an indication of the superb quality of the machine it was transporting and protecting. Simple instructions and easily assembled, once filled with oil and fuel it fired on the first pull and was immediately put to work !
    Extremely powerful and haven’t found any marks yet on my cobbled drive it won’t shift.

  7. Philip Parkin

    Delivered on time, easily assembled and up and running without any issues, great machine.

    My Wilks TX750i Petrol pressure washer was dispatched & delivered quite quickly under the difficult COVID-19 Lock down conditions. The packing crate it came in is very strong with a wooden internal base & a reinforced cardboard lid so the washer arrived without damage. The accessory pack was missing from the order which meant I had not nuts, bolts,axle for wheels or special nozzles but a quick email to the UnionMart support team had this rectified within a couple of days and delivered by courier.
    The pressure washer is assembled very easily with only a couple of parts to add to the sturdy frame and the wheels to fit, all quite simple to do.

    Once I had added the oil to the crankcase (oil not supplied so you will need about 500ml) and added some fuel it started first pull of the recoil starter.

    This is a serious piece of kit and the pressure is
    very powerful indeed, I stripped the paint from my garage door ready for painting in a couple of hours. The engine is quite noisy but nothing more than a petrol lawnmower. There is an engine speed adjustment lever to adjust the water pressure output slightly. THE BUILD QUALITY is excellent and so far I am very pleased, as for longevity I cannot comment as it’s only been a few days but from what I’ve seen so far I think the unit will last well as the Himore pumps are known to be very strong & robust.

    I looked at many petrol pressure washers before buying the TX750i and this is by far the best value for your money. Top grade engine & pump, 30m of reinforced high pressure hose,A sturdy frame with big wheels, plenty of nozzles and exta’s (Drain cleaner & Rotating Turbo nozzle) along with a good customer support make this a must have buy and I recommend it to anyone!

    Manual is downloadable from website.

  16. John Dawson (verified owner)

    Even though recently advertised as a BACK ORDER, my TX750i was surprisingly shipped extremely quickly. What an excellent sturdy, versatile and powerful unit it is. I cannot fault it at all! Well done everyone!

  17. Robert poyser

    Top pressure washer, good built qaulity, excellent run time , makes light work of cleaning decking and caravans
    Super fast delivery good comms , plenty of attachments , and for a small cost a karcher attachment allows use of snow foam equipment , good value for the money

  18. Lee Hargreaves

    Great product. The quality feels really good and the power of the machine is excellent.

  19. grahamblackwell1

    amazing bit of kit !

  20. John Backhouse

    One of the best power washers I’ve used, east to start and a sturdy frame

  21. Tony

    Works well great value with the length of hose and attachments. 
    Instructions are poor or I missed a section so some thinking is needed when building most the tools there to assemble the machine you will need a spanner and grips to put some pipe connections on, use plenty of the provided PTFE tape and you will have no leaks from fitting. 
    I turned the pull start 90deg clockwise, only 4 bolts… this make the rope and handle come out on the right so it’s not in the way of the hose reel makes it much better for starting.  
    You have to put engine oil in as instructed, there no level on the filler caps so either measure 550 ml or pour it in and the level the engine and the oil level should Settle and  come to the top of the threads, this is important too little and it will start then cut out due to low oil Safty cut out and if you keep trying the engine will seize. 
    Starting is full choke if cold and  either first pull and your away or you have to pull again….but release any pressure in the high pressure water line buy squeezing the lance handle….if you don’t you can feel the resistance against you when pulling again….this make it a lot easier to pull the second time…. I have the water connected as I’m not sure the pump likes running dry.
    There also is a throttle leave so make sure that’s at full throttle for starting….this can be adjusted once running and this will alter your pressure of the lance, but two slow and it might stall when you use. 
    Like it’s been said be aware of you hoses as the exhaust will melt them in a heartbeat if touches it. 
    It seems quiet well built but time will tell, although I was told it has a 2 year guarantee when I bought it?….but seen all spares available at a good price too 

  22. René Terrier

    Très bon appareil – très puissant – longueur de tuyau intéressante pour grandes surfaces – Diversité des pièces d’utilisation très interesante

  23. Dan Bowry

    What a fantastic machine…. Was recommended it by matt and what an awesome piece of kit, easy to assemble, easy to use, the power of this is amazing, we have just started our own business and this paid for itself in the first day, great cuatomer service… Matt you are a legend for getting this out to us so quick despite the back log, highly recommended piece of kit,

  24. David Bull

  25. Mark Bolton

    Great pressure washer for a reasonable price. we bought this to clean out the drains on our football pitches and it works a treat
    easy to assemble and simple to use


    I like this machine it is powerful yes it takes a little bit to get used to so once you know how to use it is absolutely fantastic it is important that the adjust the pressure of water that is going into the machine if it’s too high it can actually stall it however overall I like to give It 5 Stars as it really is a good machine. Very powerful to get all the stubborn stains from your stones and patios and it’s well built.

  27. Derek Thomson

    Great piece of kit, powers through the work, so glad I purchased and was delivered three days early to boot!

  28. Paulie

    proffessional quality,works like a dream easily mobile and stable during use, without toppling over as with other brands.

  29. Milo

    Had other washers before, but this one is on a different level so powerful does the job in half the time and robustly built if well maintained will last for years a excellent product

  30. K Abdul

    Came very quickly, easy to assemble although the instructions could be a bit clearer. Easy if you are in the least technically minded, but some may struggle a little. All in all a great package, go for the TX750i with the GREAT addition of a hose reel which makes life much easier. The huge 30 metre hose will be a great boost for cleaning the slabs around the house. The washer itself is much quieter than my old Kraft Stahl and way more powerful. Very happy with my purchase.

  31. Walter M

    Received well packaged no damage, easy to assemble only basic fitting knowledge required plus common sense. Filled with oil / fuel connected to water supply and off I went on my driveway. Started first pull and was amazed at pressure and ease of use.

    Well worth the cost and would highly recommend to all., who are looking for a sturdy well built pressure washer.

  32. Matt

    Well packaged and great build Quality, the manual is a bit basic and could be improved, not sure what the spare fittings are for. The washer itself is amazing, practice with nozzle options first, other wise it may take of more than you intended. A super value product with excellent performance.

  33. Lyndon

    Fast delivery ,great powerful pressure washer and very good value for the money. I had one minor problem, the turbo nozzle did not function properly after about two hours use, contacted union-mart and I received a replacement the next day! That is what I call a great backup service. So a big fat 5 stars from me.

  34. Anonymous (verified owner)

    the most powerful pressure washer I’ve ever used. Perfect for my sandstone slabs ! removed all the black spots that even the best Karsher barely touched before. amazing finish and easy product to assemble and use.

    Brilliant machine, well built

  35. M Dickon

    A beast of a washer!

    Very powerful, nice selection of nozzles, especially love the turbo nozzle. Just used it to clean a few years worth of grime from a patio and actually needed quite a bit of effort to hold the lance down. Take care when using a narrow nozzle, this thing will take the paint off surfaces and cut into the surface of timber.

  36. Steve Andrews

    Purchased the Pressure washer for home and work use. Very impressed with the quality and ease of operation. Great value for money.

  37. Barry C

    A fantastic machine,its got enough power to strip paint easily this is the real deal its good on fuel aswel its sturdy and easy to move around

    Its hard to find fault really Im going to buy a surface cleaner for it and alter its attachments to quick release eventually but aftr my first 5 jobs with it im very pleased and for the price compared to others ….u do the maths

  38. Satpal Dhoot

    Very pleased with my purchase. arrived well packaged, was easy to assemble. All the tools to assemble and maintain the machine was a bonus. Would have preferred a colour manual but adequate.

    tried on small areas and found that it works well.

    Very pleased with the purchase

  39. Satpal Dhoot

    Very pleased with the purchase. Arrived promptly well packaged and all in tact. Lots of tools provided to assemble and maintain. Would have prefered a colour manual but adequate.

    used it clean slabs works well, as with any pressure washer best to have waterproofs.

    well made and happy with how it functions.

  40. O’hara

    Fast delivery, item in great condition, have just used it and it is superb – blows the socks of my old electric karcher 🙂

  41. Ian Bunting

    I bought this machine a couple of weeks ago to replace yet another failed Karcher which are obviously not up to the job.

    I`ve just finished jet washing my drive and wood decking and they both look brand new…….the Petrol Wilks USA TX750i really did a fantastic job thanks to its massive power and nozzle choices for the various parts of the job in hand.

    I did however have a couple of problems at first which lead me to call Union Mart technical guys who sorted things out and soon had me going again.

    I cannot rate this machine and the support highly enough.

  42. Philip

    Excellent pressure washer. Used it for over 10 hours now renovating a neglected drive and decking. When used with the turbo nozzle it cuts through crud and rips up moss and weeds. Far superior power compared to my Karcher 6.5.

    I had a leak on the link hose, a replacement was quickly sent by technical service team. A*
    BTW you need to fill with oil and then replace the oil after 5 hours of duty. It takes about 1/3 of a litre.

  43. neil m

    This is my first pressure washer and its nice and easy to use. Does a great job and assembles in under 1 hour.
