The iRobot R801020 Vacuum Cleaner is a robotic vacuum machine that is self-propelled and cleans automatically without a person operating it. The Roomba 801 model is cordless so that it can move around freely and has an edge-cleaning feature for the corners of the room. It is bagless, and instead, has a compartment for storing collected dirt, and thanks to its HEPA filter, the vacuum, captures small particles such as pollen.
