Q My upright vacuum cleaner seems to be going through belts every couple of months. ABelt life is directly related to the care you give your upright vacuum cleaner. These machines move a surprising amount of air for a small appliance, at least 60 to 70 cubic feet per minute. An overfilled bag greatly reduces cleaning efficiency. When you replace the bag, check that the exhaust port is clear.
Large debris can damage the fan and the bearings the brush rides on.
Also remember to change the drive belt every four months. The belt stretches with use, and a stretched belt slips on the brush, wasting energy and reducing its cleaning ability. The brush on these machines runs in the 5,000 revolutions per minute range, so it won't take long for hair and fibers to work under the end caps, straining the brush bearings and burning up the belt. Turn the vacuum over after every use, and remove hair and fibers from the roller ends and where the belt meets the roller. News Jobs AP Shopping Archives Entertain.
