A vacuum cleaner is a device that uses an air pump to create a partial vacuum to suck up dust and dirt, usually from carpeted floors. The dirt is collected by a filtering system or a bag for later disposal. Most households in America with carpeted floors possess a domestic vacuum cleaner for cleaning. Office-cleaning and janitorial services also usually own either a domestic or industrial vacuum cleaner. There are several different types of vacuum cleaners, including upright, canister, built-in or central, back-pack, robotic, and hand-held. All vacuum cleaners use supplies that may need to be replenished. These supplies can include vacuum bags, filters, belts, attachments, and spare parts.
