chefwong- For wheelwells the nozzle/wand you showed there might be just the thing. I have a flexible nozzle for my (always inop ) Karcher that's basically the same thing and it's probably the best thing I've tried for non-mechanical cleaning of such areas. Better than the garden-hose-powered ones like what Griot's sells IMO, not that I've ever tried one of those.
I dunno...I just prefer doing them via mechanical agitation :nixweiss Devil's advocate argument: wouldn't want to blast [stuff] up into crevices and/or hit some wheelwell cladding the wrong way with too much pressure; a PW would mess up stuff in my MPV's one rear wheelwell where the cladding isn't all *that* securely attached and it'd be too much for some of my other vehicles too (but, uhm..."OK dummy, just turn the PW down a bit" does come to mind though ).
Heh heh, if my PW weren't dead I might be using it, so take the above line of reasoning for no more than it's worth. With the Blazer all winter-dirty at the moment you have me thinking that I wish my PW were working
The shuttle series is nice and I was looking at their 1900 model series as well. But during operation, it still needs to lie horizontal - so I opted for their Quadro series. I stuck with the K499 for more versatility even though I'll only be using it at home.
