Roomba 780 features Dirt Detect™ Series 2 technology which helps the robot perform concentrated cleaning in the dirtiest areas. Roomba 780's touchpad eliminates buttons and gives you control of the robot at the touch of your fingertips. Room-to-room cleaning tells Roomba to clean one room before moving on to the next. The Full Bin Indicator lets you know when the dust bin is full and needs to be emptied.
Let the robot do the dirty work.
Roomba uses a patented 3-stage cleaning process to vacuum carpets, hardwood, tile and laminate floors on its own, automatically adjusting to different floor surfaces as it moves through your home. Roomba 780's cleaning features include:

Clean under the bed and other hard-to-reach areas.
Roomba provides comprehensive cleaning coverage – vacuuming in tight spots, under and around furniture and along baseboards. Roomba 780 features:

Every home is different.
Roomba maximizes cleaning by adapting to your unique household environment. iAdapt® Responsive Navigation Technology monitors the cleaning environment more than 60 times per second, using multiple sensors (like cliff detection) and dozens of behaviors (including wall following) to clean your home. Roomba 780 adapts to your home using:
Less work for you.
Roomba knows which areas to clean – and those to avoid. Virtual Wall® Lighthouses confine Roomba in one room until it is clean and then lets it move into the next room, ensuring the robot methodically cleans multiple rooms. Roomba also charges itself, going back to its Home Base® to dock and recharge between cleanings. More 780 convenience features include:
