A vacuum cleaner comprises: a housing and a motor fan assembly mounted in the housing, the motor fan assembly arranged to generate an air flow. A removable dirt container is mountable on the housing and in fluid communication with a dirty air inlet and the motor fan assembly. A moveable dirt compactor is mounted in the dirt container and moveable between a stowed position and a dirt compacting position wherein the moveable dirt compactor is closer to one end of the dirt container in the dirt compacting position than in the stowed position. Wherein the dirt container comprises a primary handle for actuating the moveable dirt compactor with a first hand and a first auxiliary handle for allowing the user to grip with a second hand.

A suction apparatus is provided, including a suction head, a suctioned material container for accommodating suctioned material, a suction blower device arranged on the suction head, and a channel device associated with the suction blower device for conducting process air at the suction head, wherein a pipe element with an adapter device is provided, wherein the adapter device is fluidically releasably connectable or connected to a suction port of the suction apparatus for performing a suction operation and the adapter device is fluidically releasably connectable or connected to a first air outlet for performing a blowing operation, and wherein an air inlet opening of a second channel for supplying process air from the suction blower device to a second air outlet is closed by at least one wall element of the adapter device when the adapter device is properly connected to the first air outlet.

An artificial intelligence cleaner may determine a length of a head from user cleaning information including a height of a user, a pressure sensing value applied to the head and a head angle between the head and the ground using a head length calculation model and control a head motor to have the determined length of the head.

The disclosure provides a fan assembly and a vacuum cleaner with the fan assembly. The fan assembly includes a motor, an impeller and a fan housing. The impeller is driven by the motor, which includes an impeller air outlet and an impeller air inlet. The impeller air inlet is located in the axial direction of the impeller, and the impeller air outlet is located in the radial direction of the impeller. An air channel is formed inside the fan housing, and the impeller is at least partially housed in the fan housing. The impeller rotates relative to the fan housing about the rotational axis, the generated airflow enters the air channel during the rotation of the impeller, and the height of the fan housing in the direction of the rotational axis increases along the direction of the air flow.
