Background and Identification
Roombas by iRobot are robotic vacuums designed to travel around a house’s floor and clean it. Roombas achieve this through a variety of sensors that allow them to detect obstacles, drop-offs, dirty areas, etc. The first iRobot Roomba was released in September of 2002. It had physical buttons for different room-size settings. In 2004, iRobot came out with the 400 series of Roombas, which employed automatic room-size detection technology. Additionally, these Roombas had a larger dust bin and a faster charging time. The concept of a “Virtual Wall” was introduced in the 500 series version (released in 2007), allowing users to prevent the robotic vacuum from going past a certain point. Since the 500 series, iRobot has released numerous other Roomba series, each having notable improvements from the last.
The iRobot Roomba 800 Series was released in 2013. It had a more powerful cleaning system and a longer-lasting battery than previous models. The iRobot 890 featured Wi-Fi connectivity, meaning it could be started with an app.
Roombas in the iRobot Roomba 800 Series are circular robotic vacuums that sit close to the ground. They have wheels, a variety of sensors, internal electronic components, a battery, a dust bin, etc. They are black and brown in color.
