If you choose a vacuum cleaner with a bag, all dust and dirt will end up in the dust bag. Once in a while, you empty the bag. You do this regularly, so that the suction power of the vacuum cleaner remains high. When purchasing a new vacuum cleaner it is good to know how you will use it. If you have pets, for example, you choose a model with a powerful turbo brush. For vulnerable floors, for example wood, you go for a vacuum cleaner with a parquet brush.
