Abstract:
1. A vacuum cleaner module comprising: a module housing; a dirt separation housing removably mounted in the module housing and defining a cyclonic airflow chamber for separating contaminants from a dirt-containing airstream, the housing further comprising an inlet opening for the cyclonic chamber adapted to be connected to a suction cleaning nozzle and an airstream outlet opening in an upper central portion of the dirt separation housing and in communication with the inlet opening; an airstream suction source mounted in the module housing and fluidly connected to the cyclonic chamber inlet opening, the cyclonic airflow chamber and the airstream outlet opening to establish and maintain a tangential flow of a dirt-containing airstream within the cyclone airflow chamber as the airstream flows between the cyclonic chamber inlet opening and the airstream outlet opening for separating dirt from the air stream in the cyclonic airflow chamber; a support element mounted in an upper portion of said dirt separator housing; a dirt-collecting chamber within the module housing and beneath the cyclonic airflow chamber to collect dirt separated from the dirt-containing airstream in the cyclonic airflow chamber; and a separator plate mounted to a lower portion of the support element above the dirt-collecting bin, and separating the cyclonic airflow chamber from the dirt collecting chamber.
