Cyclonic separating device for upright vacuum cleaner and upright vacuum cleaner having the same

An upright vacuum cleaner, comprising:

• a brushroll;
• a motor assembly comprising a motor housing and a motor disposed within the motor housing, wherein a rotating axis of a motor drive shaft and a rotating axis of the brushroll are disposed in a non-parallel manner, and the motor drives the brushroll by a drive belt and is rotatable between a first upright position in which the drive belt is tensioned and a first oblique position in which the drive belt is loosened;
• a body assembly comprising a body, a bridging member mounted on the body and a cyclonic separating device comprising a dirt cup comprising an air inlet and an air outlet, a filter disposed in the dirt cup and comprising a filter inlet and a filter outlet communicating between the filter inlet and the air outlet, and a cyclonic cone assembly comprising a cyclone cylinder and a cyclonic guide, wherein a first end of the cyclone cylinder is connected to the air inlet, and the cyclonic guide cooperates with a second end of the cyclone cylinder and is detachably fitted over the filter to spirally guide dirty air introduced into the cyclone cylinder from the air inlet to the filter inlet, and the bridging member is rotatably connected to the motor housing to make the body rotatable between a second upright position and a second oblique position;
• wherein the bridging member causes the motor to move from the first oblique position to the first upright position when the body moves from the second upright position to the second oblique position.
