I bought one of these about 18 months ago it was used to for pre spraying carpets but now iam using it for window cleaning the thing is it dosent seem powerfull enough iam using fan jets but when the water is coming out of the brush it looks like pencil jets measured it iam getting about 1.7 litres per min is that the average for these backpacks.Ive also gt a cheap chinese trolley use that at setting number 4 find that to be miles better and quicker is 1.7 litres enough or can i get a bigger pump for the backpack cheers Darren.

check all the connectons are secure.
If you used it a fair bit before perhaps the battery needs replacing

The WCW backpack has one flow rate, that between 1.5 and 2 litres per minute.

Matt thats what i thought mine gives out about 1.7litres per min but still dosent seen powerfull enough i read on here that people were complaining that the flow rate was to high with these backpacks iam finding the opposite .

[Susan @ MB Window Cleaning]

Darren I find its is ok to clean the windows mate. I use pencil jets though.

sound slike air in system somewhere. had this yesterday afte ri changed my brush over the flow out was rubbish. checked connectors and fixed

The pump hose kinks badly and restricts the flow, straighten it out and it will fly out. It's inside the black base.
