I use an Xtreme stiff for first cleans and the Xtreme natural bristle on maintenance. I think these are fantastic brushes, considering their size and light weight. I have just bought a 35cm Xtreme with 4 jets, i'll be trying this today.
let us know how you get on with the 35 cm brush . That would be great .
First day using the 35cm Xtreme natural bristle brush.
It's not much heavier than the standard brush, it cleans evenly across the whole width of the brush and the jets are well placed. I have the smaller 4 x 1.4mm jets in this brush and there is enough flow...just. Probably the equivalent of 2 x 2mm pencil jets (if that makes sense). It seems a very good brush indeed with the same scrubbing power as the smaller version. I had snail trails today and no problem, even with cold water.
Do I like it? I'm not sure.
It definitely feels odd and I had to change my technique (like i've got one!) You have to learn to clean the frames AND glass at the same time. Normally I whip round the frames, twice over the glass and a quick rinse...'jobs a gooden'!
With this brush you can't help but clean everything at the same time, so then I had to focus on rinsing (but then it's got 4 jets) so no real problem. It does feel very unwieldy, but that's because i'm not used to it.
Verdict.
I have some bungalows with massive windows and this will be great for them. I think it would also be great for commercial jobs, shop windows (although I will still trad mine), solar panels, blocks of flats and...dare I say it...'splashing and dashing'. If I changed the jets to 4 x 2mm and upped my flow, this would be a very formidable tool. With some practice, you could really crash out some work with this.
Would I use it every day for house bashing? Brushes are very personal things and i'll think i'll stick with my standard Xtremes. I prefer the 'scalpel' to the 'shotgun'. Would I recommend you try it...Oh yes, it could be a game changer for you. At the very least it will definitely suit any jobs you have with large panes. Is it any quicker? Not for me today because I was faffing about with it, but in the right hands I think it could be.
