18 litres more than enough for a first clean and so easy to carry instead of pulling or pushing a daft trolley!
save loads of time using a backpack!
theres no chance at all you could clean a house on a first clean with a 18ltr backpack without refilling none at all!
why??...seems a daft thing to say..i would of thought it would
depend on the size of property and how dirty thewindows were
i stared with a freedom trolley i found it a right ball ache dragging
it around then having to drop the barrel off and hump it over
obsticales,so i turned it into a van system and got fed up of
microbore snaggng.
backpack with ten meters of pole hose best thing i ever did
pick up put down.my works all residential though, if i had
commercial work i would want a van system.
forget trolleys they are a waste of space
