ROBOT UPRISING
Wireless robots can navigate rooms automatically, with no human input until they need to be emptied. With a series of rotating brushes and infrared lasers, these circular devices sense the boundaries of the room and sweep any dirt into their dust compartment. Robots can carry out multiple vacuuming sessions before needing to be emptied, and are charged at a docking station. Some people preprogram these vacuums so that they clean up on schedule, while others start the process manually. Most robot vacuum cleaners come with a remote control, allowing the user to direct it to specific areas or return the vacuum to its dock before it has carried out its full routine.
