So have you heard of the Roomba? It has to be one of the most amazing inventions ever! You just set the schedule and tell the robot to clean the house at certain intervals so you never have to vacuum again! I have mine set to clean Monday , wed, and Fri at 2:30 so by the time I'm home from work the house is cleaned up. It even tells me when the dirt bin is full. I'm not a salesman or affiliated with roomba in any way I'm just a satisfied customer.

I'm on my 2nd robot now, first one had a battery issue but the cost to replace didn't make sense so I bought another one. Still cheaper than most stand vacs... Anyway lately my newer roomba has been acting up. I hope the irobot corp will take care of me like they did last time!! That was something else I didn't mention, their customer service is out of this world. I only had to use them twice but both times I was very happy when I was finished with them.
Just thought I'd mention it.
