We also have a Karcher,very pleased with it,a word of caution though,OH tried to clean green moss off of old garden bench,it took it off,but also removed the varnish !
Make sure you drain all the water out of the system when you finish as in cold weather it expands with cold and can freeze - damaging the machine. This apparently is one of the commonest problems with jet washers as the machine then leaks and pressure is lost etc...my other half has done this!
Hello everybody. Am making list of comments. Its nice to get so much info. Have looked at some models and they can be quite expensive so don't want to make a mistake buying the wrong product. Many thanks.

There are two similar attachments for the Kärcher (both extend the 'gun' bit into a sort of 'rifle') that should not be mixed up:
One of them delivers a very focused jet that will strip paint, varnish etc.
Don't use it to wash your car!
The other spreads the jet more, but is still very powerful and wrongly used could still do damage, but if used at the correct distance will remove dirt, moss etc without taking off the varnish or paint underneath. It is safest used at a glancing angle to sort of 'cut under' the grime rather than hit it full on.
i would imagine butterflybrain that drives and pathways are strong enough to withstand the strong focused jet - varnished wood and car paint are definitely not!
KT53 Is right about the risk of washing out the joints.
If the joints have filled up with weeds, though, which is also quite common, sand is going to be lost anyway getting the weeds out by any means.
Silver sand can be replaced if lost from the joints but, admittedly, this is best done in dry weather because it needs to be swept over and into the joints.
If it is just moss, grime and slime on the surface that you need to get rid of I think this is where the 'T-Racer' comes in because it performs broad stroke scrubbing rather than a focused jet stream.(see Clarington above)

Hope that helps.
