Have owned about a half dozen Roomba's over the years and a couple of Scoobas which where pretty good when I had hard floors.

Anyone have any experience with the Samsung Navibot S on carpet?: http://www.youtube.com/watch?v=9y_I2XADKKs

I'd also like to know the dimensions of the docking station.

Thinking of having one sent over from AU: http://www.harveynorman.com.au/samsung-navibot-s-bagless-robot-vacuum-cleaner-with-docking-station-black.html
