Roomba Vacuum

Roomba vacuum cleaner is popular robotic vacuum cleaner made by iRobot manufacturer. As of January 2008, over 2,5 million unit has been sold. The name of "Roomba" is a portmanteau of room and rumba. It's a kind of music to your room.

There have been three generations of Roomba units, first model is the original Roomba Pro and Pro Elite, then the second-generation is Discovery series (larger dustbin, dirt detection, and optional home base) and the third generation is the newest 5xx series.

Roomba operates with internal NiMH battery (Nickel-Metal Hydride) and requires being recharged regularly from a wall plug, although newer second and third generation models have a self-charging homebase they automatically try to find (via its infrared beacon).

Charging on the homebase takes about three hours. All second- and third-generation Roombas can be used with the homebase, even if they do not come packaged with it. First- and second-generation models came packaged with a twelve-hour charger, although a three-hour rapid charger could also be used with them.
