Abstract: A vacuum cleaner has a housing and a cover moveably mounted to the housing between a closed position and an open position. A filter is carried by the cover and includes an upstream surface and a downstream surface through which working air passes. When a user of the vacuum cleaner opens the cover, the upstream surface of the filter can be seen by the user.

Abstract: A cleaning apparatus includes a housing, a base operably coupled to the housing, a supply tank, and a spray bar assembly in fluid communication with the supply tank. The spray bar assembly includes a cover that defines a protrusion and a body coupled to the cover. The body includes a fluid inlet and a fluid outlet each in fluid communication with an interior. A first reservoir is defined within the interior. The first reservoir is disposed between the fluid inlet and the fluid outlet. The protrusion is disposed within the first reservoir to reduce a volume capacity of the first reservoir. A second reservoir is defined within the interior proximate to the first reservoir. A fluid flow path through the spray bar assembly is defined from the fluid inlet, through the first reservoir and the second reservoir, and through the fluid outlet.
