A vacuum cleaner is a device which uses an air pump to create a partial vacuum to suck up dirt and dust from floors and other surfaces. Portable vacuum cleaners come in two different types – bagged and bagless. The first type uses a bag in order to collect all the debris that the vacuum picks up. Bags are designed to be replaced not reused, so the main draw backs are the ongoing cost for the replacement bags and the risk that the bags may burst whilst being removed. Bagless vacuum cleaners, on the other hand, come in two forms – one with a fixed/solid filter and one with a self cleaning filter. Fixed/solid filters can be washed and reused several times. The self cleaning type uses a fabric filter which moves during the vacuuming process. The benefit here is that the filter is cleaned every time the motor is stopped and started. These filters are designed to last the life time of a bagless vacuum cleaner. Here you can find some of the most recommendable models.
