Roomba is a series of autonomous robotic vacuum cleaners sold by iRobot. Introduced in September 2002, Roomba features a set of sensors that enable it to perform its tasks. For instance, the Roomba is able to change direction upon encountering obstacles, to detect dirty spots on the floor, and to sense steep drops to keep it from falling down stairs. Roomba uses two independently operating side wheels that allow 360° turns in place. A rotating, 3-prong spinner brush can sweep debris from square corners into the vacuum slot under the round unit.

The Roomba units have a range of models with the 400 to 900 series, which provide several different features, such as faster speed, separate sweep canister, 5x stronger vacuum, obstacle avoidance, or performance maps displayed via a phone app. However, some parts of the Roomba models are interchangeable between related models, allowing a mix/match of features, or switching into other units for longer battery operation. The 900 series Roombas also feature a camera, which works in conjunction with onboard mapping and navigation software to systematically cover floor area. Additionally, some Roomba units can adapt to perform other, more creative tasks, using an embedded computer in conjunction with the Roomba Open Interface.

Battery reliability is a frequently mentioned complaint on customer review websites. Battery replacements from iRobot cost a significant fraction of the purchase price of a new Roomba, though compatible third-party batteries are available at a lower price. The iRobot customer support website offers advice on maximizing battery performance and longevity.

All Roomba models are disc-shaped, 34 cm (13") in diameter and less than 9 cm (3.5") high. A large contact-sensing mechanical bumper is mounted on the front half of the unit, with an omnidirectional infrared sensor at its top front center. A recessed carrying handle is fitted on the top of most units.
