We had a maid when we were children, named Heda. However, Heda was actually my family's imaginary maid. Getting a Roomba and a Scooba, the floor cleaning robot wonders--we could have named them Heda I and Heda II--would have been a much more price-accessible, maid-like option, had they been around 20 years ago.
Save yourself some spring cleaning (or just general cleaning)-induced aches and pains and check out what other ATers have had to say about the Roomba and the Scooba:
• Quite a few of you have a Roomba, and there was lengthy discussion of its merits, including as a cat-entertaining tool
• Info on the floor mopping robot, Scooba, from ATChicago
• Discussion about tricking yourself into cleaning, and the use of a Roomba
• Vacuuming with pets discussion that includes the Roomba
