Pressure washer with patio brush?
Discussion
Are pressure washer patio brush attachments actually any good at cleaning patios?
I'm getting a new Indian sandstone patio laid and I normally pressure wash my current concrete patio slabs to keep them clean, but I've heard pressure washing sandstone can pit the surface leading to dirt, algae and staining being worse, so I'm thinking of using a brush attachment.
However the brush for my professional grade Karcher HD5/11C costs over £200 so need to know if the brushes are worth getting? Don't want to throw £200+ at a 12yr old discontinued model if they aren't up tp the job. Do these brushes reduce the pressure of the water hitting the patio by diverting it through multiple jets? Alternative is to apply a sealer the sandstone.

A few of us have been posting in another thread about patio attachments.

My pressure washer is basic and I've had to buy both the attachment and connector kit as separate items off Amazon in order to upgrade my 1300W washer to have patio cleaning capabilities.
The patio attachment itself also has brushes like yours, but has 3 castor wheels.
I think the bristles are there to control the debris from the blast zone and help navigate/brush water etc away rather than soften the impact. Mine will be on 1960s concrete flags though.
This is what the underneath of mine looks like. I'm not sure whether the nozzles can be finely tuned and thereby soften or intensify any jets.
If you're worried about high costs, particularly as a Karcher, I ordered my patio attachment off Amazon for about 39 quid but I've had to buy connector pieces for an additional £27. Those I bought on Friday off Amazon and even though today is Sunday, postage has been rapid as it's out for delivery today even though I opted for free standard postage.

None of the connectors that arrived earlier this evening worked. I'm pretty annoyed to say the least as I was looking forward to giving the communal footpath with its accumulated algae a good blast for once.
It has taken me long enough with the lance only in the past and it's never 100%.
I'll have to see if there's another way or other connectors that somehow managed to miss.

My Nilfisk patio cleaner comes out yearly for the spring clean, as others have said it's definitely a timesaver.
We have Indian sandstone too and as long as you don't go too fast (if you do you get a 'swirled' pattern in the grime) then it's pretty effective. Also, the attachment loosens all the grime, but I still use the lance to send it all to the drains so it doesn't end up standing on the surface.

I just use Patio Magic on mine twice a year and with an occasional sweep or hose off stays clean. Advantage is it's not slippery in Winter.
+1 for Patio Magic. I bought some a couple of years ago because my pressure washer packed up. TBH I was just going through the motions to get the job done as an interim measure and was very skeptical about it. It works a treat on the green stuff. Used it last month on my BMW soft top that was minging and that too worked a treat 
As regards the 'patio attachment' then yep also brilliant and if/when I get a new pressure washer then it would be a must. However there's no way I'd pay £200 for one :yike: I'd buy a Karcher or Nilfisk patio head and adapt the fitting to suit.
