Abstract: A handheld vacuum cleaner includes a dust cup assembly, a suction nozzle assembly and a handle assembly. The dust cup assembly includes a cup casing, an airflow generation device and a cyclone separation device, both of which are arranged in the cup casing, the airflow generation device being arranged above the cyclone separation device and positioned on a downstream side of the cyclone separation device, and an air vent being formed in a top of the cup casing. The suction nozzle assembly is mounted to the cup casing and defines a suction channel. The handle assembly is mounted to the cup casing and used to be held. With the structure, a blowing direction of the air vent is not towards a surface to be cleaned, so as to prevent the wind from the air vent blows away dust on the surface to be cleaned and hence ensure a cleaning effect.
