What is error 15 on Roomba? How to fix the error?


Roomba is a series of autonomous robotic vacuum cleaners manufactured by the American technology company iRobot. First introduced in September 2002, Roomba is a groundbreaking invention that has transformed the way people clean their homes.

One of the key features of the Roomba is its set of sensors, which enable it to navigate the floor area of a home. These sensors can detect the presence of obstacles, such as furniture or walls, and can also detect particularly dirty spots on the floor that require more attention. Furthermore, Roomba’s sensors can detect steep drops, allowing the device to avoid falling down stairs.

Over the years, iRobot has introduced several models of Roomba, each with its own unique features. 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.

Some of the newer high-end models of Roomba have additional features, such as tangle-free brushes, separate sweep canisters, and more powerful vacuums. Some models also offer obstacle avoidance, which allows the Roomba to move around objects in its path without getting stuck. Performance maps displayed via smartphone apps also help users track the areas that the Roomba has already cleaned and those that it still needs to clean.

Perhaps the most significant advancement in Roomba’s technology is the integration of a camera in newer high-end models. The camera 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. This allows for a more efficient and thorough cleaning, as well as a more personalized user experience.
