The robotic vacuum cleaner made and sold by iRobot is called the Roomba.
iRobot introduced the original Roomba in 2002, helping bring autonomous household robots into mainstream homes. Instead of requiring a person to push it like a conventional vacuum, the small, disk-shaped machine moves across floors, collects dirt, and returns to a charging station on supported models.
iRobot began as a company founded by roboticists from the Massachusetts Institute of Technology in 1990. Before Roomba, it worked on military, space, and research robots, including machines designed for bomb disposal and planetary exploration. Roomba became its best-known consumer product and one of the most recognizable names in home robotics.
Roomba is a brand name, not the generic name for every robotic vacuum. iRobot has released many Roomba models, while other companies sell competing robot vacuums under different names. Newer Roomba products may also include mapping, app controls, automatic dirt disposal, and mopping features.
