pulled up yesterday to clean a house... i have a van mount...
whipped my pole out from the holders on the ceiling inside the van, pulled my hose from the static , bolted reel in the van and off i went washing away,
At the same time another guy i know pulled up with his van, .. humped his trolley out then started filling it from 25l container.... by now i had done the front...
went and did the back of the house and came back ..finished ! reeled in my hose shut the doors.
he was still on the front upstairs next door.... as i drove off i thought to myself, poor bugger... he will have had to then hump his trolley back into the van and mess about filling it up for next cleans etc....
been there , done that with a back pack and 25l containers.
when i got the van mount my life suddenly became so much easier,
My experience of both !
