I considered a maid but decided it wasn't for me. I was having a hard time finding someone I trusted to enter my house when I'm not there. Then if I did find someone, I figure the turnover for maids is pretty high so I'd be searching again a year later. A maid service is out. They are underpaid and being taken advantage of in too many cases for me to even consider it.
There is a Roomba that sanitizes floors exactly as you described it. It's called a Scooba. I'm getting one.
The bathroom you describe is pretty sweet. It's like the bat cave of bathrooms. I don't think my wife would go for it, plus we rent so that would likely tick off the landlord...but I have no idea why public bathrooms don't do this.
