Abstract
Official abstract text for this publication.
A vacuum cleaner has a screen cage that is permanently attached to a lid that fits on a receptacle. The screen cage has multiple layers of screens with different screen sizes, including an inner support that has greater rigidity and larger apertures that the primary screen, and an outer screen that also has greater rigidity and larger apertures than the primary screen, and is made of a different material than the support. A replaceable filter mounts to a power head that can be removed from the lid while the lid remains attached to the receptacle, and nests in the screen cage. A thermal cutoff shuts the vacuum cleaner off when the temperature of air in a part of the flowpath exceeds a limit.
