The invention provides a vacuum cleaner ( ) having a chassis ( ), supporting wheels ( ) mounted on the chassis ( ), drive means ( ) connected to the supporting wheels ( ) for driving the supporting wheels ( ) and a control mechanism for controlling the drive means ( ) so as to guide the vacuum cleaner ( ) across a surface to be cleaned. A cleaner head ( ) having a dirty air inlet ( ) facing the surface to be cleaned is mounted on the chassis ( ) and separating apparatus ( ) is supported by the chassis ( ) and communicates with the cleaner head ( ) for separating dirt and dust from an airflow entering the vacuum cleaner ( ) by way of the dirty air inlet ( ). The separating apparatus ( ) comprises at least one cyclone( ). This type of separating apparatus is not prone to clogging and therefore the pick-up capability of the cleaner ( ) is maintained at a high standard.
