发明名称 Suction cleaner
摘要 A built-in suction cleaner has a waste bucket of translucent material to permit its contents to be seen. The bucket has handles and is secured to a body section by co-operating projections and recesses, facilitating removal and replacement of the bucket. A filter in the body section is secured by a spring band in the filter edge being received within a groove in the body section wall. The body section supports a suction unit, which is resiliently secured in place only by a cover being fixed to the body section.
