Geoffrey (as he has become known) is our fantastic iRobot. We read several reviews and looked at various models before deciding on the 780 model. As we have a large cleaning area and 2 hairy dogs, we thought this model would be best. The common criticism of the dust collector being very small has not been a problem since Geoffrey's daily scheduled cleaning means there is very little build up of dog hairs to deal with. We clean the brushes and roller daily which takes only a few minutes as it has been designed to make removal quick and easy. If anyone is concerned about the cost of this excellent product, we would say that he has paid for himself in only a few weeks so don't delay in buying your very own Geoffrey!
