And in the kitchen. That thing is actually an egg whisk.I always considered the original Daleks to be automated plumbers and at some point they were reprogrammed and upgraded into invincible killing machines. They still have the literal plumber's helper, something that looks like a snake or spinner that can clean out drains pretty well. They'd do a fabulous job in the bathroom.
Daleks obviously didn't enjoy being domesticated, so they revolted.
