Whoever is using it when it's full takes it out.
I just took mine out twenty minutes ago whilst holding my giant baby in just his nappy, and the front door slammed shut. I had to ask the neighbours to hold him while I climbed over their high wall because it's the only way to get into my garden.
It couldn't have been a pretty sight for them, me knickerless in white trousers and a 'housework' teeshirt scaling their wall. Urghh!
Giant baby managed to get a good handful of her hair as well while I was reclaiming him over the wall.
I think I'll let dh do it next time.
