Company officials claim the NaviBot's brushes clean right up to the walls and take care of pet hairs without tangling.
The NaviBot finds its way around with the aid of a camera and 38 sensors. A 'virtual guard' can be set up to exclude it from a particular area, and it can be programmed to clean rooms in a particular order.
The NaviBot goes on sale this month in two versions. The base model is $A799 and comes in grey; an extra $A200 buys a more advanced unit that can clean according to a daily schedule, incorporates a touch screen control panel, and includes two virtual guards and extra brush accessories.
