This past Christmas, my oldest son gave me a Roomba. I love being able to put that baby to work while I go about my business.
I still occasionally whip out the the "big red monster" vacuum to do a bit of deeper cleaning on our rugs, but for the most part, the Roomba has freed up a lot more time for me to do other things. I LOVE it!
I can set it up to stay in certain areas or let it loose to have free reign all over the house. And when Roomba is finished or the battery is getting low, it finds it's way back to it's docking station to recharge.
Roomba, where have you been all my life?
