come on, - I'm bored -how many products to clean my floors? How bout a lawn mower? Someone else mentioned that on this board. A paint bot? A glass cleaning bot for high rises? Come on, Irobot -use your imagination -give us something really new.....
new products would be great, but i wouldn't discount the effect of the roomba/braava lines improving incrementally. if you've owned one you know they work pretty darn well—and if it gets just a little smaller, a little smarter, and a little cheaper, they could very easily sell twice as many, or more.
it's early stages, robots are...complicated, but from my experience they make a quality product, and the valuation rightly reflects a bright future should they continue to execute.
however an autonomous lawnmowing robot with spinning blades is in my opinion a dicey proposition. i would stick to products that can't take your foot off if they malfunction.
