Robotic Vacuum Cleaners have been around since 1996 made by Electrolux. They're used for cleaning, while some have spinning brushes, mopping, UV sterilization, or even Security Cameras. At first, the vacuum cleaner worked well but it had problems with colliding with objects and it stopped a short distance from walls and other objects. It also left small areas that were not cleaned. This caused a discontinuation of the product. However, in 2002 iRobot, an American advanced technology company, launched the Roomba. The Roomba can change direction when it encounters an obstacle, detect dirty spots on the floor, and can detect steep drops which keeps it from falling down the stairs. It became popular very fast, which then caused other companies to return the idea of a robotic vacuum cleaner. An advantage using a Robotic Vacuum Cleaner is how quiet it is compared to regular vacuum cleaners. Also, they are move convenient to use due to the fact it can vacuum on its own. Not to mention the size difference, the robotic vacuum can be kept under beds, desks, closets; as to a regular vacuum cleaner requires a large amount of space. With all positives, negatives follow. One down fall to the robotic vacuum cleaner is that it takes a longer amount of time to vacuum an area due to how small it is. They tend to also be a pricey investment starting at $50.00 all the way to $1,800.00.
