Europe is a key strategic region for iRobot and provides an excellent opportunity for further growth. As announced on July 25, 2017, the acquisition will enable iRobot to capitalize on the current market momentum, driving accelerated adoption of robotic floor cleaners. The EMEA region comprised approximately 25% of iRobot's 2016 consumer revenue. Robopolis represented nearly half of iRobot's EMEA revenues in 2016.

Amazon just announced a blockbuster deal to buy the home robotics company iRobot for $1.7 billion. The pending acquisition would be Amazon's fourth-largest ever, after the purchase of grocery chain Whole Foods in 2017 ($13.7 billion), the movie studio MGM in 2021 ($8.45 billion), and the medical provider One Medical last month ($3.9 billion).

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.[2] 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.

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,[4] which the vacuum detects and treats as a physical wall, prompting it to stop and turn around. Third-generation and newer models are compatible with the Dual Mode Virtual Wall, which, in addition to simulating a straight wall, can create a circular barrier roughly 4 feet (1.2 m) in diameter. Some 500-, 700- and 800-series models are compatible with the Virtual Wall Lighthouse.[5][6] It initially confines the vacuum to one area to be cleaned; then, once the vacuum reports the area has been sufficiently cleaned (based on its estimated area), it directs it to proceed to the next space to be cleaned, and contains it there.[7]

All Roomba models can be operated by pressing the "Clean" button on the top while the Roomba is on the charging base, causing it to reverse off of the base and begin cleaning; or by manually carrying the Roomba to the room to be cleaned and pressing the button. Later models introduced several additional operating modes, such as "Spot", which cleans an area of a few feet, and "Max", which cleans endlessly until the battery is depleted, this mode was only available on older Roombas. "Dock" mode, introduced with the third generation, instructs the Roomba to seek a charging base for recharging. The availability of the modes varies by model. Many second- and third-generation Roombas, and certain newer models (such as the 880),[8] come packaged with infrared remote controls or special control panels, allowing a human operator to "drive" the Roomba to areas to be specially cleaned.

Roombas are driven by two independently-operating side wheels, which can drive the Roomba forwards and backwards as well as perform turns of any radius, including 360 turns in place. Rotary encoders on the wheels can detect the rate at which the wheels are spinning so it can determine if they're slipping or stuck, and drop sensors detect if a wheel is too low (such as getting stuck in a vent). An undriven swivel caster (located at the front of most models, and at the back of the D-shaped S series) is used not for steering, as is often believed, but as an additional sensor. It too is a rotary encoder; the caster's wheel is half black and half white, and optical sensors detect the change in color as it rotates. This helps detect if the Roomba is stuck or beached (i.e., the drive wheels are spinning but the Roomba isn't moving).

Roombas before the seventh-generation models do not map out the rooms they are cleaning. Instead, iRobot developed a technology called iAdapt Responsive Cleaning Technology.[9] This relies on a few simple algorithms, such as spiraling, room crossing, wall following, and random walk angle changing after bumping into an object or wall. This design is based on MIT researcher and iRobot CTO Rodney Brooks's philosophy that robots should be like insects, equipped with simple control mechanisms tuned to their environments. The result is that although Roombas are effective at cleaning rooms, they take several times longer to do the job than a human would. The Roomba may cover some areas many times, other areas only once or twice, and may miss some areas. However, the random algorithm has been shown to effectively cover rooms of various sizes and configurations, particularly when used repeatedly for maintenance cleaning. (Some users have used long-exposure photography or compositing to create images showing Roombas' coverage of the floor,[10] and have even attached light sources to Roombas to create art using light painting.[11][12] Some have also noted that doubts about the effectiveness of the random algorithms have been assuaged by multiple reports of Roombas rolling over dog feces and spreading it through the room, which rather unpleasantly illustrate how well the Roomba can cover the floor's area.[13][14]) Roombas have become a common example of how randomized algorithms can probabilistically succeed even though they cannot absolutely guarantee success on any single run or even after many repeated runs. Compared to competing products available when Roombas were first introduced such as the Electrolux Trilobite, the effectiveness of Roombas' random navigation was on par with (or even more effective than) robotic mapping technology available at the time, and being cheaper to develop and produce, could be offered at a significantly lower price.[15]

Starting with the seventh generation, Roombas have an upwards-facing camera and a downward facing infrared floor-tracking sensor which are used to create a map of the floor.[16] This enables them to use a more efficient back-and-forth cleaning pattern, which is faster and more efficient as it ensures more complete coverage without needing to cover an area multiple times. The floor-tracking sensor operates like an optical mouse and can provide precise movement data over small distances, but suffers from integration drift: small errors in measurement which accumulate over time. To rectify this, the upwards-facing camera is used periodically to identify waypoints or "landmarks", coarse points that are used to correct the Roombas' position and map.[16][17] Some algorithms such as wall following are still used, partly to assist in mapping the floor and also simply to make sure the floor is cleaned along the edge and around obstacles. Unlike other mapping systems like lidar which can operate in complete darkness, Roombas' camera requires some light in the room in order to be able to map it. Starting with the eighth generation, Roombas retain the map after each run, and use subsequent runs to improve the map. Multiple maps can be stored, and users can edit maps to separate and label regions (such as rooms), which can be used to have the Roomba clean only a selected room.

The Roombas' bumper allows them to sense when they have bumped into an obstacle, after which they will reverse or change paths. Infrared "cliff sensors" on the bottom of Roombas similarly prevent them from falling off ledges such as stairways. (These may also trigger a false positive on dark or black colored surfaces such as some carpets, preventing Roombas from entering or being able to clean those areas.) Third-generation and newer models have additional forward-looking infrared sensors to detect obstacles. These slow down the Roomba when nearing obstacles, to reduce its force of impact.[18] It's also used to clean alongside walls without bumping into the wall repeatedly. This technology is also able to distinguish between hard and soft obstacles.[citation needed]

Roombas are not designed for deep-pile carpet.[citation needed] Also, the first- and second-generation Roombas can get stuck on rug tassels and electrical cords.[citation needed] Third-generation and newer models are able to reverse their brushes to escape entangled cords and tassels. All models are designed to be low enough to go under a bed or most other items of furniture. If at any time the unit senses that it has become stuck, no longer senses the floor beneath it, or decides that it has worked its way into a narrow area from which it is unable to escape, it stops and sounds an error to help someone find it. Early models use only flashing lights to indicate specific problems, while later models use a synthesized voice to announce a problem and a suggested solution.[20] The voice is available in several languages. 041b061a72
