Backpack vacuum cleaners are basically canister type vacuums that mount onto the users back with a type of harness. These are useful in places where other types of vacuums wonâ??t fit. Primarily used in the restaurant industry because they can be maneuvered under tables and chairs to vacuum the floor, without physically moving all of the tables and chairs out of the way. Most backpack vacuums have a slightly larger 1-Â˝ inch diameter hose to resist clogging from larger debris. These machines can be used in almost any commercial, or residential environment. Backpack vacuums come with a universal, straight-suction floor tool for carpet and bare floors. Some brands offer an optional carpet nozzle with a revolving brush for use with wall-to-wall carpeting.
