Patent Images
1. An upright vacuum cleaner comprising:
- a base for movement across a surface to be cleaned;
an upright housing pivotally mounted to the base;
a module mounted to the upright housing and having a cyclonic separator chamber for separating contaminants from a dirt-containing airstream, the housing further comprising an inlet and an outlet in fluid communication with the separator chamber, and a collection chamber for receiving contaminants separated in the separator chamber;
a suction nozzle mounted to the base and fluidly connected with the inlet;
a suction source mounted in the upright housing and fluidly connected to the suction nozzle and to the separator chamber for establishing and maintaining a dirt-containing airstream from the suction nozzle to the inlet;
a frame mounted in the upright housing;
a first filter positioned in the frame upstream of the suction source; and
a second filter positioned in the frame downstream of the suction source and juxtaposed to the first filter.

Abstract
An upright cyclonic vacuum cleaner comprises juxtaposed first and second filters for filtering a working airstream on both the inlet and outlet sides of a vacuum motor. The first and second filters can be mounted in a common frame in the upright housing of the vacuum cleaner. The first and second filters can be juxtaposed to each other.
