Well in the 5 and a half years I've been wfp cleaning I can honestly say I've found the best brush for me, I've used lots of different types in that time and the Tecbuk hybrid does everything I want. Ye sure it's not the lightest out there but by no means is it heavy, anyone that says it is man up a little bit and get some shoulder muscles lol. I've been using it on first cleans and maintenance cleans and it does both with no problems. Gets rid of spider sacks in corners which I did worry at first. One of the main things I find is it gives me confidence in cleaning leaded glass as other brushes feel like there gonna start to peel it off all I can say is if you looking for a new brush give it a go, and before you say yes I payed full price, only thing I did was change the y connector to the standard as felt the quick fit ones lowered the pressure as they have a bigger diameter.
