Concept
Roomba
Summary
Roomba is a series of autonomous robotic vacuum cleaners made by the company iRobot. Introduced in September 2002, they have a set of sensors that enable them to navigate the floor area of a home. These sensors can detect the presence of obstacles, particularly dirty spots on the floor, and steep drops (e.g., to avoid falling down stairs).
As of 2022, iRobot markets models of their 600, i, j, Combo and s9 series, while continuing to provide support and sell accessories for their previous series. Various models have different features, including tangle-free brushes, separate sweep canisters, more powerful vacuums, obstacle avoidance, and performance maps displayed via smartphone apps. Newer high-end models also have a camera, which works in conjunction with onboard mapping and navigation software to systematically cover all floor area, move from room to room, avoid obstacles such as pet waste and charging cables, and find recharging bases and beacons.
Roombas allow some customizability and reprogramming. Parts of some models are interchangeable, allowing owners to mix and match features, or switch to other units for longer battery operation. Additionally, some units can be adapted to perform more creative tasks using an embedded computer in conjunction with the Roomba Open Interface.
Most Roomba models are of a disk shape, measuring in diameter and high depending on the mode. The S9 and S9+ robots are D-shaped rather than circular, with the flat part of the D at the front, and are narrower at wide. A large contact-sensing mechanical bumper is mounted on the front half of all models, with an omnidirectional infrared sensor at its top front center. Most models also have a recessed handle on top.
First- and second-generation Roombas were not compatible with the Virtual Wall, an accessory used to prevent them from entering an area. It projects a pattern of infrared light, which the vacuum detects and treats as a physical wall, prompting it to stop and turn around.
