The housekeeping maid,is pretty inoffensive.
She has pretty much everything to keep the house nice, tidy and free of dust with her sensors specifically tuned for it. You might think she's too small (3 feet is the universal size) to reach any high places but she can actually hover pretty high up and maintain a stable height. She also has extendable arms to get to high places. She's gentle as well. She's also equipped with a built-in vacuum on her back with a potent turbine to clean everything.
