Hello chaps, We did used to sub lots of window cleaning out from our office cleaning company, we do still sub a little out now still but we did by from a local guy a cheap set up to do our own, we now have the system to produce the water, a 1000 litre tank at the store a 300 litre tank on the van and poles ect, it works well, at what point should we consider upgrading the kit to a fully fitted on board system. Is it necessary ?? We will be looking to tender some large commercial work and take on some more residential work.
Any advice would be good. Ta
