  1. Sean

    Had a little problem at first, would cut out after 5 mins, found the problem, the fuel bowl bolt was loose and sucking air, secured ran absolutely brilliant machine, fantastic power, this is a beast of a machine, nice 5ltr tank,looking forward to using it more.
    Another note for the novice user, release water pressure from gun, the machine pull start works a whole lot easier.
    Very happy so far.

  2. Scott G

    Had to send back as it was a bit too powerful for my needs.

    I can’t give it a proper review for this reason, but I can say the customer support was very reasonable and allowed me to return.

  3. Henrik B

    Easy to sample, added oil and petrol and started first time. Substantial piece of machinery but 4 wheels makes it easy to position where needed. Impressive pressure with a variety of attachments making this a very useful tool for all sorts of cleaning jobs.

  4. Mckenna A

    If I had to be picky I would say the cord is a little hard to pull, but maybe that is just me getting old.

    No cheap plastic parts, a metal pump and proper rubber wheels not those plastic rubbish ones you normally see these days. A Proper American Brand.

    Reminds me of how tools and machinery used to be made, although I can only speak for this particular model.

    Thanks.

  5. O’Neil

    Highly recommended to any fellow farmers who may be looking for something with a bit more power than what you can buy on the high street. Electrical cord is a reasonable length and you can feed it straight from a barrell which has turned out to be useful for us as we don’t have hose connections on some parts of the land.

  6. Colchester

    As my dad used to say, BUY CHEAP BUY TWICE.

    After getting ripped off previously from a ‘national’ brand we decided to spend the money on something a little more expensive. I am extremely pleased we did. There’s a reason most of the reviews mention the power…

  7. terrence

    As others have said this is most suitable for business/industrial use… I wouldn’t use this on your flowerbeds..

    We have used a variety of makes/brands over the years and (so far at least) this has got to be my favorite.

    The build quality is exceptional and the wheels are very sturdy. We’ve been using this for about 2 months now on a almost daily business and I am happy to report there is no noticeable loss of power.

  8. Keeton

    Arrived the next day and so far so good.

    Probably the most powerful ‘portable’ pressure washer I have ever used for my cleaning business.

    Only time will tell how durable it is.

    Definitely recommended for anyone looking for something with high power

  9. Jack M

    Bought this as a replacement for an old pressure washer I had and the only thing I can say is WHAT A BEAST. Works perfectly for what I use it for.

    Although the TX850 is perfect for me I would say it is not a great buy if you are only going to use it for household chores – I would recommend one of the less powerful ones.

  10. Neil Mitchell

    Excellent power washer and a fantastic price a serious bargin

  11. Hughie

    UNREAL POWER.
