The common mistakes you can make when using a vacuum cleaner include vacuuming debris that is too large for the vacuum cleaner. Certain pieces of debris can jam vacuum cleaners and that may damage the device. This is an issue that happens more often with upright vacuum cleaners than with shop vacuum cleaners, as shop vacuums often have wider nozzles and can pick up larger pieces of debris. Another mistake is setting the vacuum on the wrong speed and surface setting. The right setting on the vacuum cleaner should be chosen to facilitate the best vacuuming of the surface being cleaned. Carpets, hardwood floors, and upholstery all might require different levels of suction so if one's vacuum has a dial to adjust for these options that should be accounted for when vacuuming. Another mistake is using the wrong type of vacuum to clean pet hairs. A vacuum's brush roll may get tangled if pet hairs are picked up by the vacuum cleaner so it is important to use a tangle-free vacuum cleaner to remove pet hairs from surfaces.
