The presence of a rotating brush in a vacuum cleaner depends on the type of vacuum cleaner you have. There are two main types of vacuum cleaners with different brush configurations:
Upright Vacuum Cleaners: Many upright vacuum cleaners have a motorized brush roll or beater bar located at the base of the vacuum head. The brush roll typically has bristles that spin rapidly as the vacuum cleaner is in use. The purpose of the rotating brush is to agitate the carpet fibers, dislodging dirt, dust, and debris, making it easier for the vacuum's suction to lift the particles into the vacuum bag or dustbin.
Canister Vacuum Cleaners: Canister vacuum cleaners usually have a separate motorized powerhead that attaches to the main canister unit via a hose. This powerhead also contains a rotating brush roll for carpet cleaning, similar to upright vacuum cleaners.
However, not all vacuum cleaners have a rotating brush. Some vacuum cleaners are specifically designed for hard floors and may lack a brush roll to prevent scratching or damaging delicate surfaces like hardwood, tile, or laminate. These models often rely solely on suction power and specialized attachments for cleaning various surfaces.
So, if you have an upright or canister vacuum cleaner designed for carpet cleaning, it should have a rotating brush. If your vacuum cleaner is designed for hard floors, it may not have a rotating brush. Always check the manufacturer's specifications and product details to understand the features and capabilities of your specific vacuum cleaner model.
