If you have an upright vacuum, you may find that it looses "pick-up" power. The first step to saving your vacuum and your carpets is to clean it out. Fibers and hair gets wrapped around the beater and should be removed every few weeks (or more if you have indoor pets). There are also a variety of hoses and filters that should probably be cleaned. Check your owners' manual for more details and instructions. Making your appliances last longer can save you a bundle.
