You can clean your house today without having to lift a finger. All you need is one of those new cleaning robots that have created such a sensation. You can then put up your feet and let the robot literally do the dirty work for you. These robots were spawned by the space exploration programmes that NASA conducted over the last 50 years. NASA created robots to wander the surface of Mars and the moon to pick up rocks and other geological samples. Today this technology makes it possible for robots to wander around your house picking up dirt. Do these robots really work well? The answer is yes, they are surprisingly effective. They have been extremely well designed and are easy to program. You just have to ensure that there is no litter such as newspapers or clothes in the path of the robot. These robots work on surfaces like carpeting, wooden flooring and even concrete. They can pick up anything from food particles to hair to dust and are equipped with sensors for navigation. If the sensor senses an obstacle, the robot will merely change direction to avoid the obstacle. Some robots are equipped with a “virtual wall” a laser beam beyond which the robot may not go. This ensures that the robot is restricted to the area that you need cleaned and does not go wandering all over the house. The robots are extremely easy to program and all you need to do is to estimate the size of the room to be cleaned and set the control panel accordingly. The batteries are easy to recharge and robots will clean up from one to three rooms on a single charge. If the robot gets snarled up in cloth or an electrical cord, it beeps a warning so that you can go and unsnarl it. These robots are perfect for proud homeowners who believe in keeping up to date with their home mortgage payments and in maintaining their house so that it retains its value.
