iRobot Roomba Vacuum RobotFor centuries, technology has been at work to make peoples' lives easier. From basic conveniences like running water, indoor plumbing, and hot water, to more advanced machines like dishwashers, washing machines, and dryers, technology and electronics have been slowly taming household chores and giving people more free time. One chore that has been around since the days of dirt and brick floors is cleaning those floors - brushing, washing, dusting, sweeping, mopping, vacuuming, there always seems to be dust, hair, food scraps, and junk in general laying about the ground. Bulky vacuums have been around for a long time, and they do a decent job of cleaning hard surfaces and carpets. Mops work well on stone and tile surfaces. The advent of the Swiffer a few years back changed the way many people cleaned with simplified dusting and mopping of kitchen floors, but it still required manual time and effort.
How does Roomba work?The Roomba looks to change this entire cleaning paradigm, by combining artificial robot technology and intelligence with a mini sweeper and vacuum system. Developed by iRobot Corporation, the Roomba is a small robotic vacuuming appliance. How does Roomba work? Looking something like an electronic, thick frisbee on wheels, Roomba has a system of small brushes and vacuum suction. It has a 13" diameter and is circular in form. It is battery powered, and works best on smooth surfaces like tile or hardwood, but can also handle non-pile carpets. It's intelligent cleaning system allows it to make its way around the room or rooms where you place it, going under tables and chairs, along edges of walls, while avoiding stairs and other pitfalls. It knows to turn around and back up when it comes into contact with walls and doors, and it stops and circles areas where it finds lots of debris, meaning better cleaning for those problem areas. In a normal cleaning cycle, it will cover the entire floor area 3 or 4 times. View all iRobot Roomba models here
Sure, this may not be the smartest most efficient machine, but it does a pretty thorough job. Due to its low profile, it can also clean under beds and couches, places tough to reach with a normal vacuum. Roomba cleans in a 3 stage process. First, little spinning brushes along the front edges sweep dirt towards the center of its path. Next, 2 spinning brushes pick up hair and larger particles, again through a sweeping motion. Lastly, a squeegee vacuum picks up any remaining fine particles, dumping everything into a removable bin for cleaning. You can tell it areas to clean and avoid by using either of the included 2 Virtual Wall units -- place these in front of a doorway and they emit a signal that Roomba picks up, stopping it in its tracks at that invisible line (of course if you have a door there, you can just shut it as well). How long do Roomba batteries last? It should be able to clean 3 medium sized rooms (14x16 feet) in a single charge.
