iRobot Roomba 790 Vacuum Cleaning Robot

At $699.99 (direct), the iRobot Roomba 790 is even pricier than some of the best traditional vacuums on the market.

It takes about three hours for the Roomba 790 to get a full charge, and it spent about an hour vacuuming my 450-square foot apartment.

The Roomba 790 uses iRobot's Dirt Detect Series 2 technology, which utilizes an acoustic sensor to detect excessive amounts of small and hard debris, like sand, and an optical sensor to detect large and soft debris, like popcorn.

The Wireless Command Center has five primary functions. Most importantly, it allows you to initiate cleaning just by pressing the Clean button, so you can start up your Roomba no matter what room you're in.

The Wireless Command Center uses radio frequency to transmit signals through ceilings and walls up to 25' away from the Roomba.

The Roomba 790 measures 14 inches in diameter, stands just under 4 inches tall, and weighs 8 pounds, which is similar to other competitive devices.
