Emptying the compost bin is a snap. Let it go as long as you can still easily turn the mixing lever. The longer, the better — months, if possible. When it comes time to empty the bin, simply remove the upper chamber (toilet bowl part), remove the liquid container, stretch a plastic trash bag over the top of the compost bin, release the mounting knobs at the floor brackets, lift the bin and turn it upside down. All the stuff will tumble into the trash bag. Don't worry about cleaning out the bin — the old bits of microbe-rich compost stuck inside will jump-start the composting process again. Just put the bin back into the mounting brackets, add fresh peat moss or coconut fiber, and reinstall the upper chamber (bowl) and the liquid container. You're good to go (so to speak).
