Cleaning the house made easier

I came across a rather tempting device today.
I have been thinking about getting a vax, for cleaning the carpets a little more thoroughly than just suction will, and instead found something that may clean them slightly less thoroughly but will do so without my total attention.

Roomba robotic vacuum cleaner


Sounds like fun.
I did find someones comment that it worked well but needed an extra bit of prgramming to tell it to run and hide when children were around.
