1. A motor, fan and dirt separating means arrangement for a vacuum cleaner, the arrangement comprising:

  • a motor with a drive shaft;

    a fan coupled to the motor for generating air flow; and

    a dirt separating means located in a cleaning path of the air flow generated by the fan, the cleaning path being between a dirty air inlet and the fan,wherein the motor is located in a cooling path of the air flow generated by the fan, the cooling path being between a clean air inlet and the fan, wherein the air flow through the cleaning path is substantially greater than through the cooling path in normal operating conditions and wherein the cleaning path and the cooling path of the air flow combine where the cleaning path is downstream of the dirt separating means and upstream of the fan and the cooling path is downstream of the motor and upstream of the fan;

    wherein the motor is nested within an inner wall of the dirt separating means; and

    wherein the clean air inlet and the exhaust of the combined cleaning path and cooling path are located on a same side of the dirt separating means.
