This would have to be wrong.

This would ban laundry hampers, dirty clothes would go straight into the machine.

I think the rule would be if you pick up the item from the “take-off” point it goes away.

You have to be able queue things before the clean. OP isn't cleaning, they are constructing the queue. You would be allow to move from queue to queue I guess, but you'd have to make sure there can't be a topographical loop.
