You can buy a hose bag for about £50 i think. Make a circle on the floor then pop it in the bag, simple.
I got my mum to make me a bag (she's a dress maker) and its fantastic. It has a strap that goes around my shoulder, like a gym bag and in the "sack" I have space for hose, soloution line, priming hose and CFR hantool if needed.
The really good thing about it is that it leaves my hands free to carry a wand and sebo duo in one hand and a sprayer, buckets and spotting kit tote bag in the other
Might upload a pic off it tomorrow if i can be arsed.
p.s. hose reel for a porty
waste of space in the van if you ask me.
