Pressure washing a filthy patio using a Karcher K4 pressure washer

Jet washing dirty paving slabs on a patio using a Karcher K4 Full control pressure washer. The T5 surface cleaner and the dirtblaster lance Karcher K4 attachments are used to clean neglected paving slabs and remove weeds growing between them. Karcher stone and paving cleaner is used on the slabs before and after pressure washing.

After my older Karcher pressure washer failed I bought a Karcher K4 Premium Logic. It failed within warranty and had to be replaced and then failed yet again after very little use. Karcher quoted £145 to service and fix it but I bought a fantastic AVA Smart P160 currently on sale from the manufacturer for £199. Much more power including a patio cleaner and with a 10 year warranty. Tremendous performance and quality and so much better than the karcher K4. The reason I bought the AVA was the excellent reviews on YouTube by Epic. Epic tests many machines and said the K4 was lacking in pressure. The features and engineering of the AVA are brilliant.

I would add that the AVA uses the same fitting as the Karcher so you can keep your accessories although you might have to cut a little plastic off the Karcher screw collar to allow the bayonet to fit snuggly. It also has an extendable lance which really helps prevent backache plus a Snow Foam Cannon. I also bought a Bosch 6 metre pressure hose extension for £15 from Amazon. Whats not to like.

excellent video! keep up the good work 😁

Great video, very clear. Only sealing afterwards I am unsure about.

It could be cleaned more. There is still a lot of embedded dirt .I recommend using the intensive nozzle. It takes longer but will improve the look even further. An annual clean will then suffice.

I bought the k4 new series by watching the videos. It has no problems in washing the floor and car, but the drain opening apparatus does not work with pressure. I called the customer services many times to take it to the service, then I took it to the service, but this way it is without pressure.
It was said after the test they did that it worked. I can say that it was a failed apparatus. They did not receive a refund. My money was a baton.

2 questions - 1 why did you have to push the bottle on so hard - should be an easy drop in place (mine is). 2. Why was no detergent coming out? When I use ours with the stone cleaner (great stuff) it really foams up nicely - might be worth checking it’s working properly as it makes a massive difference

[johnwilson]

You get a cleaner finish by useing just the lance and as for a cleaner washing up.liquid brush over the are left and lanced over this allni ever do.all the bedt

[jd-xz]

I wonder if you need to use the detergent or if T5 surface cleaner would do the work even without it. Thanks.

subscribed! Will this work on porcelain slabs?

10-1 mix of chlorine in a watering can, sprinkled over area, as a final step to kill any residual mould.

[Fraptor-cobq]

Can you you please tell me when using this k4 pressure washer with T5 patio attachment what is the pressure reading on your handle ?
Is it mix, soft, medium or hard ?
I have one and it’s only showing medium, I would really appreciate it if you could come back to me ?
Great Channel thank you 🙏

[arvindtaylor]

I have a problem detergent not coming out, does it only come out on low pressure settings? When taking the bottle out the nozzle on the machine side looks it’s gone in at an angle! Is that normal?

[zsoltpasztor]

Can I use it without a tap water (which is under some kind of pressure) and get water from a water tank (clean rain water), water bucket?

[MrKChurchill]

Our one isn't dispensing detergent when using the T5 - is it by design that the detergent only comes out on the mix lance?

[sallywells]

I have just set up the Karcher 4. I am not getting any visible change to the pressure gauge in the handle of the gun. I am twisting the wands to High but that seems to make no difference. The videos dont refer to this. Is there anything else I should be doing. The spray is not powerful enough to remove dirt from slabs as shown in the video.

[anthonypaul]

Not sure if my surface cleaner is working very well it’s the Kärcher t351 and the symbol on the Lance shows soft, is that correct or should it be higher, I’ve turned the dial on the surface device to max.
