Abstract

A vacuum cleaner including a debris separator that includes a housing, a cyclonic separator including a cylindrical wall having a first end and a second end. The cylindrical wall is located in within the housing and the cyclonic separator further includes a dirty air inlet, a clean air outlet, a debris outlet adjacent the second end, and a longitudinal axis surrounded by the cylindrical wall and the longitudinal axis of the cyclonic separator extends in generally a horizontal orientation. The debris separator further includes a lid coupled to the housing and the cyclonic separator is coupled to the lid such that the cyclonic separator is removable from the housing with the lid. A debris collection chamber is located within the housing and in fluid communication with the debris outlet of the cyclonic separator.

Claims

1. A vacuum cleaner comprising:

a suction nozzle;

a suction source operable to generate an airflow through the vacuum cleaner from the suction nozzle through a debris separator to a clean air exhaust;

the debris separator operable to separate debris from the airflow, the debris separator including,

a housing,

a cyclonic separator including a cylindrical wall having a first end and a second end, the cylindrical wall located in within the housing, the cyclonic separator further including a first end wall located at the first end of the cylindrical wall, an dirty air inlet, a clean air outlet that extends through the first end wall, a debris outlet adjacent the second end, a longitudinal axis surrounded by the cylindrical wall and the longitudinal axis of the cyclonic separator extends in generally a horizontal orientation,

a debris collection chamber located within the housing and in fluid communication with the debris outlet of the cyclonic separator,

wherein the housing forms a second end wall of the cyclonic separator located at the second end of the cylindrical wall,

further comprising a divider wall that extends from the cylindrical wall of the cyclonic separator to the sidewall of the housing such that the sidewall of the housing and the divider wall define the debris collection chamber.

2. The vacuum cleaner of claim 1, wherein the housing is generally cylindrical.

3. The vacuum cleaner of claim 1, wherein a generally cylindrical portion of the housing defines the debris collection chamber.

4. The vacuum cleaner of claim 1, wherein the housing defines a portion of the debris outlet of the cyclonic separator.

5. The vacuum cleaner of claim 1, wherein the dirty air inlet is adjacent the first end of the cylindrical wall.
