I would suggest you need the patio cleaning attachment as well - circular thing with rotating jets. It makes a better job of it.
Then spray with Patio Magic or similar which keeps the mould in control for months.
Well with my one I bought the patio cleaner, the telescopic jet pipe and the angled head. I plan to get the rotating car brush and alloy wheel cleaner too. I also planned to regularly clean my gutters facials and car. So far my plan is not working! I watch too much telly, I’m too lazy and ....why hurry, what’s the worry? Plenty of time to do that stuff.Thing is a Karcher K7 is £400 or something, if you do your patio every other week then fine but if you only do it once a year or so it's kind of an expensive toy ....
