Chill out chappy..wasnt making a point directly at you,was simply
making the point that you dont get the same problem with hewitt
packs.

but if you want to get your knickers in a twist

Well good for you!

am chilled out dude 
just a bit of sarcasm aimed at this forum, lowest form of wit I know 

remember the old style wcw backpacks ? they were so much more comfortable to carry by the handle than these new style ones with handle on the lids.
The handle i have made for my gardiner one is far more comfortable to carry by if nothing else, plus you do not have to check every time that the lid is screwed on so tightly 

much easier on a trolley!

Except when you encounter, steps, soft grass, stones, going through houses, etc etc etc

yesterday i had a few jobs where its a bit of a pain with long hoses so used the backpack for 4 jobs.love it!

i wish id bought one years ago.i reckon ill use it on around 30-40 jobs a month.easy to fill up.takes 2 mins from van tank outlet.

one job i cleaned 18 windows with one fill(19L full to the brim)on full flow.

no snagging hoses or untangling.just fill up and go!

great addition to my van mount.im well impressed.

Doesn't seem that long since you were questioning why window cleaners would want to use backpacks

The back packs also good for putting virosol in for gutters and conny roofs use mine all the time for that

The whole point of a backpack to me is to be able to clean away without hoses getting dragged through junk and avoid  going through dog muck!carry through houses etc.

Putting it on a trolley would defeat the object of even using a backpack in the first place!!

KS van mount is king on most work but backpacks certainly have there uses!!I was wrong!!!

I always use it on my back, that is what they are made for being a backpack!.
I only have it 1/4 or 1/2 full though.

i never went back to my van mount, or pure freedom trolley, when i bought my

wcw b/p, which im still using, on a shopping trolly, got a gardiner one as back up to,

that was nearly three years ago,

There is a big difference putting a backpack on your back and using a for crop spraying ( which they were initially made for)  as opposed to cleaning windows at height with a WFP tho.
