Roomba was introduced in 2002. As of Feb 2014[update], over 10 million units have been sold worldwide. Roomba features a set of basic sensors that help it perform tasks. For instance, the Roomba is able to change direction on encountering obstacles, detect dirty spots on the floor, and detect steep drops to keep it from falling down stairs. It uses two independently operating wheels that allow 360 degree turns. Additionally, it can adapt to perform other more “creative” tasks using an embedded computer in conjunction with the Roomba Open Interface.

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.
As of 2012, there have been four generations of Roomba units: the first-generation original models, the second-generation “Discovery” series, the third-generation 500 series and the fourth-generation 600/700/800 series. All utilize a pair of brushes, rotating in opposite directions, to pick up debris from the floor. In most models, the brushes are then followed by a squeegee vacuum, which directs the airflow through a narrow slit to increase its velocity in order to collect fine dust. A horizontally mounted “side spinner” brush on the right side of the unit sweeps against walls to reach debris not accessible by the main brushes and vacuum. In the first generation of robots, the dirty air passes through the fan before reaching the filter, while later models use a fan-bypass vacuum.
The Roomba is powered by removable nickel-metal hydride batteries (NiMH), which must be recharged regularly from a wall power adapter. Newer second and third generation models have a self-charging homebase which they automatically try to find at the end of cleaning session via infrared beacons. Charging on the homebase takes about three hours. Four infrared “cliff sensors” on the bottom of the Roomba prevent it from falling off ledges such as the top steps of stairways. Most second- and third-generation models have internal acoustic-based dirt sensors (The Dirt Detect Series 1 Technology) that allow them to detect particularly dirty spots (zones having excess particulates) and focus on those areas accordingly. Fourth generation models have an optical sensor located in front of the vacuum bin (The Dirt Detect Series 2 Technology) allowing Roomba to detect wider and smaller messes. Many second and third generation Roombas come packaged with IR (infrared) remote controls, allowing a human operator to “drive” the robot to areas to be specially cleaned.
Some higher-end 500 and 700 series robots are compatible with “Virtual Wall Lighthouses”, which use RF to communicate. These more-advanced Virtual Wall accessories confine a Roomba to a fixed area to be cleaned, yet allow the cleaner to later proceed to the next space to be cleaned.
iRobot has released several types of dust and debris collection bins for the 500 Series robots. The standard “Vacuum Bin” incorporates the separate squeegee vacuum, as with all prior models. The “High Capacity Sweeper Bin” does not include a vacuum, but has greater capacity for debris collected by the brushes. The “Aerovac Bin” directs suction airflow through the main brushes instead of using a squeegee, which is thought to keep the brushes cleaner.
All Roomba models can be operated by manually carrying them to the room to be cleaned and pressing the appropriate button. Later models introduced several new operating modes. “Clean” mode is the normal cleaning program, starting in a spiral and then following a wall, until the room is determined to be clean. “Spot” mode cleans a small area, using an outward-then-inward spiral. “Max” runs the standard cleaning algorithm until the battery is depleted. “Dock” mode, introduced with the third generation, instructs the robot to seek a self-charging homebase for recharging. The availability of the modes varies depending on model, generally with higher-end units having more features.
The robot’s bumper prevents them from bumping into walls and furniture by reversing or changing path accordingly. The third- and fourth-generations, which move faster than previous models, have additional forward-looking infrared sensors in its bumper to detect obstacles. These slow down when nearing obstacles to reduce its force of impact (Light Touch Technology). Additionally, this technology is able to distinguish between soft and solid barriers. After a sufficient period of time cleaning, the Roomba will either search for and dock with the homebase, or stop where it is.
The cleaning time depends on room size and, for newer models equipped with acoustic dirt sensors, volume of dirt. First-generation models must be told the room size, while second- and third-generation models estimate room size by measuring the longest straight-line run they can perform without bumping into an object. When finished cleaning, or when the battery is nearly depleted, a second- or third-generation Roomba will try to return to a homebase if one is detected. A second-generation Roomba may also be used with the external Scheduler accessory, allowing cleaning to start automatically at the time of day and on days of the week that the owner desires. Most 500 Series robots support scheduling through buttons on the unit itself, and higher-end models allow the use of a RF remote to program schedules.
Unlike the Electrolux Trilobite vacuuming robots, Roombas do not map out the rooms they are cleaning. Instead, iRobot developed a technology called iAdapt Responsive Cleaning Technology., Roombas rely on a few simple algorithms such as spiral cleaning (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‘ 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 as long to do the job as a person would. The Roomba may cover some areas many times, and other areas only once or twice. The Virtual Wall accessories project infrared light beams which the Roomba will not cross. Newer model Scheduler Virtual Walls can be set up to turn on via IR at the same time a Roomba is activated. As Virtual Walls are battery-powered, this is desirable to avoid wasting power projecting IR beams when not needed.
The Roomba is not designed for deep-pile carpet. Also, the first- and second-generation Roombas can get stuck on rug tassels and electrical cords. The third-generation is able to reverse its brushes to escape entangled cords and tassels. Additionally, 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 it 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 its owner find it. Early models use only flashing lights to indicate specific problems, while later models use voice synthesis to announce a problem and a suggested solution.
General maintenance of the Roomba consists of emptying the debris bin and cleaning the dust filter, as well as removing and cleaning the brushes. Excessive hair accumulation in the brush system can cause the brushes to stall, or overload the brush motor, damaging the unit. Lesser amounts of hair build-up will merely slow down the brushes, reducing cleaning effectiveness and battery life. Special “pet-friendly” options and models are available, which are supposed to be more resistant to hair build-up, and easier to clean.
Battery life and reliability
Battery reliability is a frequently-mentioned complaint on the iRobot, Amazon, and other third-party 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 batteries will gradually lose energy capacity, resulting in shorter cleaning runs, eventually necessitating replacement. Roomba batteries are end user replaceable within minutes.
When a Roomba owner is absent for an extended period (such as a vacation or due to illness), automatically scheduled cleaning runs should be canceled. For example, if it becomes entangled and stops with an error sound on an unattended session, the battery will remain deeply discharged for an extended period, often resulting in permanent damage to the battery.

Introduced in 2002, the first-generation Roomba had three buttons for room size. The first-generation units comprise the original, silver-colored Roomba, the blue Roomba Pro, and the maroon Roomba Pro Elite. The latter two models included additional accessories, but all three use the same overall core robot and cleaning system.
The second-generation Roombas (dubbed “Discovery”, later called “400 series”) replaced their predecessors in July 2004 (although pre-release models were available Q4 2003), adding a larger dust bin, better software that calculates room sizes, dirt detection and fast charging in the home base (or wall hanger in the case of the Discovery SE). All second-generation Roombas are functionally identical, though some have more or fewer buttons, accessories, or different external designs. Version “2.1″ contained updated software and a new front wheel. Version “2.1″ was issued in 2005, and the update was made available to existing units as well. The low-end models continued to be available after the introduction of the 500-series with new, three-digit model names.
Roomba budget models (Dirt Dog and Model 401) have a simplified interface (a single “Clean” button) and lack some of the software-controlled flexibility of other versions. They are positioned to be less-expensive versions of the Roomba for first-time purchasers. The Roomba Dirt Dog contains sweeping brushes and a larger dust bin, but lacks the vacuum motor. It uses the space that would be required for the vacuum for additional dust bin volume. It was designed for home shop or home garage environments. The Dirt Dog was discontinued in 2010. The Roomba Model 401 is similar but has a “standard” size dust bin and vacuum system. Budget models are upwards-compatible with the extended-life batteries, fast charger and schedulers of the 400 series.
The third-generation 500 series Roomba was first introduced in August 2007, and features a forward-looking infrared sensor to detect obstacles and reduce speed, a “Dock” button, improved mechanical components, smoothness of operation & a modular design making part replacement trivial. It also introduced customizable decorative face plates. The Roomba 530 came with two Virtual Walls and a recharging dock.
The 500 series have been superseded by the 600 series in August 2012. All models come with the AeroVac bin and the Advanced Cleaning Head:. (Also see the “List of Models 2012+” below)
In January 2011, iRobot announced the Roomba 700 Series robots. Although largely similar to the 500 series, the 700 series features a number of improvements. Among these are a more robust cleaning system, improved AeroVac bin with HEPA filter and improved battery life.
Like the 500 series, the 700 series includes robots with different technologies and accessories. The Roomba 760 is the simplest of the robots, and Roomba 790 is the second newest and advanced with both scheduling and a large range of accessories including Lighthouses, Wireless Command Center and extra brushes and filters. Besides these two models, also Roomba 770 and 780 are available – both with scheduling, DirtDetect 2 and full bin indicator.
The updated models started shipping in May 2011.
In 2013, iRobot announced the Roomba 800 series robots. The 800 series is similar to the 700 series and its predecessors, but contains updated technology.
The AeroForce™ Performance Cleaning System, the iRobot XLife™ Battery are some of the new features. The 800 series Roombas contain all of the older technology that hasn’t been updated from before, such as the cliff detection sensors and the bumper sensor, to aid in cleaning, and for being consistent with the previous series.

Hacking and extending Roomba
From the earliest models on, Roomba vacuum cleaning robots have been hacked to extend their functionality. The first adaptations were based on a micro controller that was directly connected to the motor drivers and sensors. Versions manufactured after October 2005 contain an electronic and software interface that allows hackers to more easily control or modify behavior and remotely monitor its sensors. One early application was using the device to map a room. The native code for Roomba is written in a dialect of Lisp
Models with an interface (400 series from October 2007 and the newer 500 and 700) come with a Mini-DIN connector supporting a TTL serial interface, which is electrically and physically incompatible with standard PC/Mac serial ports and cables. However, third-party adapters are available to access the Roomba’s computer via Bluetooth, USB, or RS-232 (PC/Mac serial). Roombas pre-October 2005 upgraded with the OSMO Hacker device allow the user to monitor the many sensors and modify its behavior. The Roomba Open Interface (formerly “Roomba Serial Command Interface”) API allows programmers and roboticists to create their own enhancements. Several projects are described on Roomba hacking sites.
In response to the growing interest of hackers in their product, the company developed the iRobot Create. In this model the vacuum cleaner motor is replaced by a “cargo bay” for mounting devices like TV cameras, lasers and other robotic parts. Create provides a greatly enhanced 25-pin interface providing both analog and digital bidirectional communication with the hosted device, allowing use as the mobile base for completely new robots. Together with a computing platform like a netbook or handheld device with wireless networking, it can be remotely controlled through a network.
