yep, summer work only... petrol pressure washer.. use customers water... even if on a meter....
any water in your van tank will last you no time,
i did a house in the summer , it had a stream running through the garden... so i sucked water out of there .

be prepared to be absolutely filthy.. dirt gets up your nose in your ears and all over the customers walls and windows...
so lots of cleaning up afterwards... and if its block paving... you will have to brush sand it afterwards (kiln dried sand).
and i hate doing them now.
