I have used several different vacuum systems and while I am thankful that each of them works, I have a favorite that I keep going back to.
I bought an upright Oreck vacuum that I just love. It is so light weight and easy to carry with me wherever I need to go. This makes the job of vacuuming so much easier for me.
It also does a good job of picking up lint and small pieces of dirt from the floor. I can use this vacuum in every area of my house as it works on carpet, tile and hard wood floors.
I have never given much thought before to how a vacuum system works, I just know that I am thankful for them. If I have to go a week or so without one, I realize how dependent I am on them to keep my floors clean.
