Okay so I'm considering changing my method of window cleaning from traditional to WFP. Any feedback would be appreciated. If I was to go down this route, I would have Brodex fit there 500ltr DI system to my van but purchase my poles from Gardiner as these seem to have the best reviews. Has anyone had any experience with brodex when it comes to their machines and installs? (I've heard there poles arn't so great, but I would not be buying one from them). What other company's would you recommend to do the install? I have been cleaning windows the trad way for 12 yrs. I already clean all my frames and sills, use gg4 with a dash of ecover, (not fairy) and am struggling to justify spending all this cash. Will I notice that big a difference. And my work is ALL domestic.
