Same deal as posted by theearth on the 15/10/12 http://www.ozbargain.com.au/node/82101
Slim design. 50mm height. Moves by itself, avoiding objects. Cleans where others can't reach and where dust accumulates.
Good info in the community comments last time it was posted. This model doesn't seem to be as good as the Roomba 530 but is around $100 cheaper. Main differences that I can see is the return to base, virtual wall, struggles with carpet and not sure about electrical leads.
I am always fascinated by this robot vacuum cleaner :D
