I started with Vikan rectangle brushes and never had a problen with them, well apart from the fact they're a bit heavier than they need be, or maybe what i 'think' they could be. I also have the oval Vikan, that has lots of really soft bristles, great for cleaning leaded windows, not so good for getting algae/moss out of UPVC frames. Thats all i'd used until recently. Oh, i got a salmon dual trim brush which seemed great but i left it on the end of my facelift 30' fibreglass as it was so light so i never used it to much !!
Now when i got my CLX poles my first few i got with the dual trim lightweight brush. Never had a problem with them, infact they seemed to easy to use, and too light. Not that there was anything wrong but i almost thought if i'm not having to work the brush hard them its not cleaning enough, although all the results from it where fine. It was just what i 'thought' a brush should be feeling like i was having a problem with. Good brush really, very soft bristles on the outside, great for cleaning glass with a sweep and if needed ,a bit of a push and you're onto the shorter stiffer ones for a dig in the grooves on UPVC to rid of moss/algae and general crap. For some reason that seemed right at the time i got my next CLX with a mono trim brush which was quite stiff. Great for scrubbing crap out of frames. Not so good for me at 25' cleaning a first clean. I got called back. Never been called back to a job before. They said the job was crap there was spots and streaks etc.... I'm not new to WFP and usually leave a first class job every time. I was mortified what i seen, i went inside to see them. On a lot of the glass it was as though someone had cleaned it with a comb, you could see where the bristles had missed the dirt and to be hionest they where really bad. Done the whole lot again with the dual trim brushes, and popped a Vikan on the end of the CLX. I'm guessing that the stiffness of the mono trim brush combined with the flex in the 27'CLX is a recipe for disaster, it doesn't give you a whole lot of scrubbing power or coverage.
Does a rigid full carbon fibre pole still give you the leverage and scrubbing power at 25'/30 feet even with a monofilament ,mono trim brush or are softer brushes always best for heights and real scrubbing power is out the question?
