The best robot we saw at CES 2019

• The Coral One vacuum is the best robot I saw at this year's CES.
• It can vacuum a floor without human input by using sensors to detect obstacles and create a map of your home.
• Unlike a Roomba or other robot vacuums, the Coral One has a detachable component that allows for manual vacuuming of elevated or hard-to-reach surfaces.
• The Coral One's biggest downside is its $599 price tag (you can buy a robot vacuum for less than half of that).

The Coral One vacuum is far from the flashiest robot at this year's International Consumer Electronics Show (CES), but it's the one I'd most like to own.

Like a Roomba, the Coral One can vacuum a floor without human input by using sensors to detect obstacles and create a map of your home. But unlike a Roomba or other robot vacuums, the Coral One has a detachable component that allows for manual vacuuming of elevated or hard-to-reach surfaces.

A robot vacuum that includes a manual vacuum may not sound as exciting as a robot that can dance, play ping-pong, or play rock-paper-scissors (all of which are on display at this year's CES), but its benefits are more practical. The Coral One's biggest downside is its $599 price tag (you can buy a robot vacuum for less than half of that), but there's no robot I saw at CES 2019 I'd rather own.
