so come on then lads are they worth the hassle?
i presume they need filling up all the time and if so cant last very long,but ae they ok for the one off awkward window or conservatory roof.
if so how much can we expext to pay for one and where from,
and how longs it gonna last
ian
from re3ading posts, they seem to work just fine,
cost max £200, ideal for one-off windows etc, yes they will need filling alot more as the tank is small. but if just doing one-off windows will last quite a while. Do a search for backpacks on here and you will find loads of posts about it, you can get one from ebay for £117 delivered (no CE mark) but same or you can buy over here nearer the £200 mark
I use a van mount so have no need as yet to buy one,
a trolley system again is a good idea if budget is limited holds more water than the backpack, then there is the van mount costs the most but then you get what you pay and can hold as much water as you need.
