I don't work carrying a bucket mate. OK, maybe my work is very compact, and I don't have to move it much during the working day, but I saw one of the guys on Youtube using a bottle on a belt, and stuck a holder on to the sides of my ladder instead. 2 bottles of 250 ml is enough for about 5 or 6 3 bed semi's. I use monsoon mops and dip them when I return to the van. A bucket weighs about 7 or 8 kiloes. Who wants to carry that about all day?
Been happy using bottles for the last 7 or 8 years.
Try it, maybe it's a good idea for you. If not, stick with lugging a bucket about.
