A good vacuum cleaner does not need a massive amount of suction power in order to work well. Think of the cordless rechargeable hand held vacuum that you love so much. As long as you’re using it on a hard surface, it picks up everything you need it to because you do not need a lot of suction to pick up debris off a hard surface. In fact you do not need a lot of suction to pick up small loose debris off a soft surface either.
Your vacuum may be making them worse
If you’re vacuuming to address allergy concerns, you need to make sure that your vacuum’s filtration system is made to the highest quality standards or your vacuum could be cleaning the floor, but dirtying your air. Watch Alan Caras, from The Vacuum Store in Los Gatos demonstrate the difference that a properly built filtration system can make in containing the particles ejected by your vacuum cleaner’s exhaust.
