iRobot® Roomba® i3+ (3550) Wi-Fi® Connected Robot Vacuum with Automatic Dirt Disposal

Dirt is any matter considered unclean, especially when in contact with a person's clothes, skin, or possessions. In such cases, they are said to become dirty. Common types of dirt include:

• Debris: scattered pieces of waste or remains
• Dust: a general powder of organic or mineral matter
• Filth: foul matter such as excrement
• Grime: a black, ingrained dust such as soot
• Soil: the mix of clay, sand, and humus which lies on top of bedrock. The term 'soil' may be used to refer to unwanted substances or dirt that are deposited onto surfaces such as clothing.

Disposal may refer to:

• Bomb disposal, the process by which hazardous explosive devices are rendered safe
• Dispose pattern in computer programming
• Disposal of human corpses, the practice and process of dealing with the remains of a deceased human being
• Disposal tax effect, a concept in economics
• Garbage disposal, a device installed under a kitchen sink between the sink's drain and the trap which shreds food waste into pieces small enough to pass through plumbing
• Ship disposal, the disposing of a ship after it has reached the end of its effective or economic service life with an organisation
• Waste disposal, the getting rid of waste materials
• Disposal, a statistic in Australian rules football referring to kicks or handballs.
• Free disposal, the possibility of discarding resources without economic costs.

iRobot Corporation is an American technology company that designs and builds consumer robots. It was founded in 1990 by three members of MIT's Artificial Intelligence Lab, who designed robots for space exploration and military defense. The company's products include a range of autonomous home vacuum cleaners (Roomba), floor moppers (Braava), and other autonomous cleaning devices.

A planned takeover deal by Amazon.com for US$1.7 billion, announced in August 2022, collapsed in January 2024 amid antitrust scrutiny by the European Commission.

A robot is a machine—especially one programmable by a computer—capable of carrying out a complex series of actions automatically. A robot can be guided by an external control device, or the control may be embedded within. Robots may be constructed to evoke human form, but most robots are task-performing machines, designed with an emphasis on stark functionality, rather than expressive aesthetics.

Robots can be autonomous or semi-autonomous and range from humanoids such as Honda's Advanced Step in Innovative Mobility (ASIMO) and TOSY's TOSY Ping Pong Playing Robot (TOPIO) to industrial robots, medical operating robots, patient assist robots, dog therapy robots, collectively programmed swarm robots, UAV drones such as General Atomics MQ-1 Predator, and even microscopic nano robots. By mimicking a lifelike appearance or automating movements, a robot may convey a sense of intelligence or thought of its own. Autonomous things are expected to proliferate in the future, with home robotics and the autonomous car as some of the main drivers.

The branch of technology that deals with the design, construction, operation, and application of robots, as well as computer systems for their control, sensory feedback, and information processing is robotics. These technologies deal with automated machines that can take the place of humans in dangerous environments or manufacturing processes, or resemble humans in appearance, behavior, or cognition. Many of today's robots are inspired by nature contributing to the field of bio-inspired robotics. These robots have also created a newer branch of robotics: soft robotics.

From the time of ancient civilization, there have been many accounts of user-configurable automated devices and even automata resembling humans and other animals, such as animatronics, designed primarily as entertainment. As mechanical techniques developed through the Industrial age, there appeared more practical applications such as automated machines, remote-control and wireless remote-control.

The term comes from a Slavic root, robot-, with meanings associated with labor. The word "robot" was first used to denote a fictional humanoid in a 1920 Czech-language play R.U.R. (Rossumovi Univerzální Roboti – Rossum's Universal Robots) by Karel Čapek, though it was Karel's brother Josef Čapek who was the word's true inventor. Electronics evolved into the driving force of development with the advent of the first electronic autonomous robots created by William Grey Walter in Bristol, England in 1948, as well as Computer Numerical Control (CNC) machine tools in the late 1940s by John T. Parsons and Frank L. Stulen.

The first commercial, digital and programmable robot was built by George Devol in 1954 and was named the Unimate. It was sold to General Motors in 1961 where it was used to lift pieces of hot metal from die casting machines at the Inland Fisher Guide Plant in the West Trenton section of Ewing Township, New Jersey.

Robots have replaced humans in performing repetitive and dangerous tasks which humans prefer not to do, or are unable to do because of size limitations, or which take place in extreme environments such as outer space or the bottom of the sea. There are concerns about the increasing use of robots and their role in society. Robots are blamed for rising technological unemployment as they replace workers in increasing numbers of functions. The use of robots in military combat raises ethical concerns. The possibilities of robot autonomy and potential repercussions have been addressed in fiction and may be a realistic concern in the future.

Roomba is a term that refers to a series of autonomous robotic vacuum cleaners made by the company iRobot, and was first introduced in September 2002. Roombas have a set of sensors which help them navigate the floor area of a home. These sensors can detect the presence of obstacles and steep drops (e.g., to avoid falling down stairs).

As of 2024, iRobot markets models of their fourth through tenth generation, while continuing to provide support and to sell accessories for their previous series. Various models of the Roomba have different features, including tangle-free brushes, separate sweep canisters, more powerful vacuums, obstacle avoidance, and performance maps displayed via smartphone apps. Newer models also have a camera, which works in conjunction with onboard mapping and navigation software to systematically cover all floor areas, move from room to room, avoid obstacles such as pet waste and charging cables, and find recharging stations.

Roombas allow some modulation 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.

In August 2022, Amazon announced its intention to purchase iRobot, though the acquisition was delayed by regulators in Europe for fear of hurting competition. As of January 2024, these plans were abandoned by Amazon.

A vacuum (pl.: vacuums or vacua) is space devoid of matter. The word is derived from the Latin adjective vacuus (neuter vacuum) meaning "vacant" or "void". An approximation to such vacuum is a region with a gaseous pressure much less than atmospheric pressure. Physicists often discuss ideal test results that would occur in a perfect vacuum, which they sometimes simply call "vacuum" or free space, and use the term partial vacuum to refer to an actual imperfect vacuum as one might have in a laboratory or in space. In engineering and applied physics on the other hand, vacuum refers to any space in which the pressure is considerably lower than atmospheric pressure. The Latin term in vacuo is used to describe an object that is surrounded by a vacuum.

The quality of a partial vacuum refers to how closely it approaches a perfect vacuum. Other things equal, lower gas pressure means higher-quality vacuum. For example, a typical vacuum cleaner produces enough suction to reduce air pressure by around 20%. But higher-quality vacuums are possible. Ultra-high vacuum chambers, common in chemistry, physics, and engineering, operate below one trillionth (10⁻¹²) of atmospheric pressure (100 nPa), and can reach around 100 particles/cm³. Outer space is an even higher-quality vacuum, with the equivalent of just a few hydrogen atoms per cubic meter on average in intergalactic space.

Vacuum has been a frequent topic of philosophical debate since ancient Greek times, but was not studied empirically until the 17th century. Clemens Timpler (1605) philosophized about the experimental possibility of producing a vacuum in small tubes. Evangelista Torricelli produced the first laboratory vacuum in 1643, and other experimental techniques were developed as a result of his theories of atmospheric pressure. A Torricellian vacuum is created by filling with mercury a tall glass container closed at one end, and then inverting it in a bowl to contain the mercury (see below).

Vacuum became a valuable industrial tool in the 20th century with the introduction of incandescent light bulbs and vacuum tubes, and a wide array of vacuum technologies has since become available. The development of human spaceflight has raised interest in the impact of vacuum on human health, and on life forms in general.
