tried my new 35cm ultimate brush out today on some offices first thing this morning,i like the 4 jets and the extra width but it took me around the same time as it usually does with a smaller brush so no time saving.....35 mins(£60-00 job).....i will be using it on some big jobs next week too....but personally i dont think i could be any quicker than i am with a smaller brush...
Have you done trad work before daz? (I can't recall)
I used to love working with a 14 inch mop n Squeegee. The speed I could work it was crazy and It took me ages to up grade onto the 18 inch ones. Mostly because I was convinced there was no point because when I helped my mate out on his work, there was no difference time wise between us and he used the 18 inch ones. However by the end of the day, I was more tired as I used a hell of a lot more energy than he did.
It's probably the same in this case for you. For instance my 35cm brush fits nicely into a side opening window, just snug. So there's no side to side movement needed, just a straight down n up and a final rinse, the job is done. Whereas the 12inch brush you have to go side to side as well as, therefore it's clearly faster in reality
