ABSTRACT:
The present invention relates to an upright vacuum cleaner including a housing and a nozzle base having a main suction opening. The housing is pivotally mounted on the nozzle base. The housing comprises a cyclonic separator including a dirty air inlet and a sidewall. A lower end of the separator being secured to a lower skirt. A dust collector section is located beneath the separator and includes a sidewall. A perforated tube is disposed within the separator. The perforated tube includes a shroud extending away from a closed lower end of the perforated tube. A diameter of the shroud is larger than a diameter of the separator lower end. The lower skirt and the shroud define a first air channel for directing air from the separator into the dust collector section. The first air channel has a substantially constant volume for maintaining airflow velocity.
