1. A vacuum cleaner, comprising:
a motor;
a fan driven by the motor;
a main body housing housing the motor and the fan, and including an intake port and an attached part; and
a cyclone unit detachably attached to the attached part of the main body housing to cover the intake port;
wherein the cyclone unit has:
a first attachment part configured to attach to the attached part;
a connection pipe having a suction port, at a front end, through which an airflow from outside enters, the connection pipe extending from the suction port to a side of the first attachment part;
a main case being a cylindrical shape, the main case including the first attachment part, and connected to the connection pipe;
wherein the main case includes:
a cyclone chamber having an inflow port communicating with the connection pipe, the cyclone chamber is a shape extending more toward a side of the suction port than the inflow port;
an inner cylindrical part which is provided in the cyclone chamber and is a cylindrical shape extending in an axial direction of the connection pipe, and through which the airflow flowing from the inflow port into the cyclone chamber passes toward the main body housing,
wherein dust is centrifugally separated with the airflow swirling around a periphery of the inner cylindrical part inside the cyclone chamber to accumulate dust inside the cyclone chamber,
wherein the cyclone unit is configured to be alternatively attachable to the attached part of the main body housing in a first state and a second state, wherein dust collection is performed in both the first state and the second state,
wherein, in a direction intersecting the axial direction, the first state is which the connection pipe is disposed at one side of the cyclone chamber, and the second state is which that the connection pipe and the cyclone chamber being disposed in the same position relative to each other as the first state but in different positions relative to a fixed point on the main body housing,
wherein the connection pipe maintains communication between the cyclone chamber and an outside of the main body in the first state and second state.
