I’ve just had a look at the link to the backpack….IMO that backpack is as good as useless for working with all day. You really don’t want to be working with a backpack ( they should be renamed😁 ) on your back. When it’s full of water it’s over 25kg, that puts a big strain on your back and neck, especially when you’re doing upstairs windows.  If he must go down the backpack route he’d be better with a Gardiner style one which has a carry handle.  Yes it can be heavy to carry if using without a sack truck, but at least you can put it on the ground when you’re cleaning the windows.

Need some advice... My son-in-law is starting up soon and to get going he plans to use a backpack and barrels. I've been wfp over 20 years but never had anything to do with backpacks. So, any advice here from those who use or have used them would be much appreciated. He sent me this link to one he had seen online, I know the pole and brush etc wouldn't be up to what us experienced guys would use but it's a start- or is it? Anyhow, he's a lovely genuine lad who would appreciate the guidance. 🙂👍

Retire and get him to do your round for a percentage 😎👊

Mind, he only has a small car so a trolley may be too big. 🤔
