ABSTRACT:
A vacuum cleaner suction device includes an upper casing member and a lower casing member that oppose each other. A rotary brush chamber in the suction device has a suction port formed therein. A turbine chamber that is separated from the rotary brush chamber but interconnected thereto through a passage formed in the partition that separates the rotary brush from the turbine chamber. The rotary brush is supported in the rotary brush chamber as is the turbine for driving the rotary brush. The turbine is rotated by an air current drawn into the vacuum cleaner. A service hole is formed on the turbine chamber of the seduction device body for partially exposing the turbine. The service hole is provided on a removable service hole cover with a locking portion for removably supporting the service hole cover. Contaminants that clog the passage to the tubing can be easily removed by opening the service hole by removing the service hole cover. Accordingly, there is no need to separate the upper and lower casing members of the suction device body. Vacuum cleaner maintenance and repair is made easier.
