hey guys so i am a traditional window cleaner but the other day i come across a women's flat which the council pay once a year to clean but she likes our monthly approach, and her flat had been cleaned using the WFS and honestly it does amaze me, but i am the one who is always doing tops. there is only 2 of us and its family run but my partner don't think the WFS is any good as he is stuck in his ways. i personally want to buy the trolly WFS system and get some practice with it and prove its well worth the £500 and can help us year more money. i will also buy the whole R/O pureifer as well. i want to use 25L barrel. with a pipe which has a trigger thing. i know it won't last long maybe 2 or 3 houses just doing the tops. but i had say 5 of them for a 4 hour day then it might work what i am asking is has anyone got this system and uses it every day.
