The problem so far with robotic vacuums it that, frankly, they've been terrible vacuums. The challenge is jamming enough cleaning power into a small form factor, so much so that it has taken Dyson 16 years and tens of millions of dollars to achieve a solution. This is where the Dyson 360 Eye (~$1200) comes in. Dyson has developed their own unique digital motor to accommodate power demands and the company hasn't stopped at just power. The bot has a full 360 degree sensor system that maps your rooms and uses key points to guide its tank track driven self around your abode in the most efficient pattern - even if that requires driving over a change in surfaces. The only issue is that you'll have to sack your cleaning service just to pay for it.
