i started with pressure washing before window cleaning, as a weekend job whilst in sales...
now i still advertise it but get little work as i push window cleaning hard....
it was a pain to be honest, filthy work , then brushing in the kiln sand...
my two machines (petrol) were 6.5bhp... not powerful enough really,
now if i get a couple of decent jobs, which is rare, i hire a honda 13hp
£35 for the weekend....
that way i am not lumbered with all that gear, and lance hose which is a pain for storage, or leaving in the van.
