Welcome, Robotic Overlords

A couple weeks ago I ordered a brand spankin new robotic vacuum cleaner. This thing is awesome. I had my doubts, but it was on woot.com so I figured, “What the hey?” Let me try to explain how freakin cool this Roomba is. It charges itself, so it lives in it’s “cradle.” You use the REMOTE CONTROL to press the “C” (for “Clean”) button, it makes some beeps while it backs out of it’s cradle (as if it is going to run over some children or an elderly lady), turns around, and goes to the middle of the room. It spins in a few circles with it’s laser-eye to measure the room, then gets to work. It lasts about 2 hours on a single charge, and does an amazing job. When it’s done with the room or it’s battery gets low, it goes back to the radle automagically and recharges. Awesome.
It also happens to be a good vacuum cleaner as well. I have a vacuum, and I do clean my house from time to time, but this thing sucks up about 2 CUPS of lint each time I run it. Gross, but cool. I guess I’m a slob. When Roomba finds a dirty spot a blue LED on his top blinks and he spins around in circles until his particle detection system sees clean air. He works well on hard floors as well.
I am worried because the manual does not list what the safety phrase is, because I just know some day this guy’s going to learn where I keep all my stuff, take it and kill me to take over my life.
Until then, I will continue to turn it on at 7:30 when I leave for work and come home to a clean house.
