Abstract

A vacuum cleaning device comprises a housing having a dirty air inlet and a clean air outlet. An airflow path extends between the dirty air inlet and the clean air outlet. A dust container is mounted to the housing wherein the airflow path goes through the dust container. A motor fan assembly is mounted in the housing and is configured to create an air flow along the airflow path in a blow mode and a suction mode. A controller is configured to control the motor fan assembly in the blow mode and the suction mode. The controller is configured to control the motor fan assembly to pulse the motor fan assembly at first fan speed when in the blow mode.
