ABSTRACT:
A dirt separation and collection container suitable for use in a bagless vacuum cleaner including two dirt separation and collection zones is provided. Dirty air enters the mid-section of the device and enters a first stage dirt separation zone including a cylindrical baffle spaced inwardly from the outer wall of the device with an inclined slot to allow coarse dirt particles and fibers to pass through and collect at the base of the outer wall of the device. The spinning air is then fed into a second stage conical separator for separating fine dirt particles and collecting them in an inner substantially cylindrical collection chamber. Air exits the conical separator and device opposite the cone opening before being drawn to the suction source. Elements may be oriented upwardly or downwardly depending upon the configuration of the housing for receiving the dirt separation and collection device.
