i bought one for my commercial customer that has an area they want cleaned a couple of times a year, i can remember the last other job i used it but im having trouble with the one before that.
you might dig a few jobs out of your customer base but not many people seem to ask for a pressure cleaning guy. i clean the dust out of one ladys alfresco occasionally but i just use soapy water and a broom. no blasting mess up the walls that way.
The main use of mine is cleaning the 217 bag
your on the right track though, if you sit waiting for work in june and july youll be lucky to be eating potatoes, i reckon at least 80% of winter work is initiated by me.
Drop the busy narrative
ask for more work
let them know you are looking for more,
suggest pruning this and that to let the light in
do that job they talked about getting around to one day
fix the flyscreens
shoot a message off to some hedges you trimmed before christmas
and enjoy the quiet time
