It's a beast! In a good way!
Friday, 2 April 2021  | 

Very impressive piece of kit!

Prior to buying I had a quick chat with one of the guys at Rutland Pumps who was very helpful & answered all my questions; & gave me several options to perform the tasks I had in mind for this machine. (True to all the comments I'd read online about Rutland Pumps & the reason I went to them to get a pressure washer!)

After describing what I wanted & why I wanted it I was offered good advice.
They didn't just push the most expensive choices; but gave me a range of products across the price spectrum & allowed me to decide which suited my budget.
Which is rare these days!

After a good discussion I selected this unit & having used it for a few days I am more than impressed with the Pressure washer.

Plenty powerful and hasn't missed a beat in all the time being used.
Starts quickly and with ease (Though I'm used to constantly having to start my machines with pull cords, if you follow the advice given when you buy one; it will start up without much effort. So again, great customer service by Rutland Pumps.)

The trolley is built like a tank and the wheels are really good for moving it over grass & uneven surfaces!

It's not unwieldy either; I can get it into the back of my Ford Transit Custom on my own & get it out on my own; which is a life saver!)

It's first job was down a large garden; so had to go over a lawn a fair distance to get too the tennis court.
& even up/down an incline, which wasn't an issue as it's balanced pretty well; so no straining and swearing!

Knowing Loncin engines (Have one in my Cobra Wood Chipper) they're built to last & perform really well.
Also pretty decent on the fuel use, given it's size & the job it does hours on end.

The hose pipe is really good quality and substantial. Rolls up nicely and in a nice tight roll!

The only downside was the Lance on the Spray gun. The nut at the end where the quick release piece is, was cracked/split. So when used the water was coming out the side of the lance and not just the end. If I hadn't of caught it on video I wouldn't have believed it (filming for review purposes & for my businesses social media etc), but as I turned the machine on with the lance for the first time & prepared to use it; the jet of water coming out of the side started as a trickle (was easing the machine in and priming it ready for use; so was taking it easy).

So will be popping back up to Rutland Pumps next week to get that sorted.

& also to see if they do a longer lance as for my personal use, would prefer a longer one.

If you're buying one of these for the first time.

Get a longer hose than you think you'll need when buying, as it will more than likely be worth it and save you moving the machine.
The Quick release options are well worth having! Huge time & effort saver!

If your/job sites water supply rate/pressure from the tap isn't great, a wheelie bin will do in a pinch; but I assure you an IBC tank or something similar would be a wise investment!!!
(Placed on site the day before perhaps, and filled up overnight/before you require water to supply the machine.)

As this thing really does go through the water at a serious rate! It drains a 150 Litre wheelie bin rapidly!

This machine has powered through cleaning a Tennis court with an 18 inch Whirlaway. Large areas of the court were thick with moss build up. It's eaten it's way through it without so much as burping.

If it wasn't for the water source being such a low flow rate & some technical issues with the Lance/Whirlaway; I'd have been done in a day working on my own.
As the lance issue made it impossible to finish up by washing down after Whirlaway'ing the court, I will have to return too the clients property next week to wash it down due to the lance having a fault; these things happen though. & I am sure it's an easy fix.

It's a nut on the end of a lance causing the issue, the Trigger gun and nozzles etc are fine.
(Not sure if Rutland Pumps do it; but having a swivel on the connector would be a serious upgrade & make life a lot easier when using the Gun though. It'd save having to fight the hose when moving about a lot! So shall be asking when I pop up there next week!)

Overall highly impressed with Rutland Pumps, & in fact have already had several conversations with others in my line of work (Bespoke Gardener & Garden Services) + a few others who showed interest in this unit when I bought it, so have already mentioned Rutland Pumps to several people; who should be paying them a visit/shopping with them soon!)

My client was also impressed, given the job/task they wanted done was hindered with a couple of technical issues; they were really happy I was able to go get the issue sorted & get back on with the job quickly.
Also commented on how good the machine performs and the build quality of the trolley etc.
(So much so they even brought some visitors out to look at it while operating & cleaning the tennis court!)

Which is great, as if my clients are not happy; then I am not happy.
So content clients = a happy gardener!

Many thanks, Simon; from Shadow of the Gardener.

Great machine great value
Wednesday, 24 February 2021  | 

Great value for the money, well put together. My only bad note is that the machine is fix to far to the right, so the pull cord handle is tight up against the trolley. Other than that it's still 5 stars from me. Would 100% use again and highly recommend

Fantastic jet wash
Thursday, 17 December 2020  | 

Recently replaced my old Honda 300 15 L per minute jet wash with a watertek Pro. The difference between 15 and 21 L per minute is incredible. Definitely worth paying the extra.

The build quality of my new jet wash from Rutland pumps is fantastic. I paid to have all stainless steel quick release connectors. I can now set up and dismantle it in seconds.

Rutlands service was first rate. From the high quality Web site to the speedy delivery. A 5 start experiencing throughout.
