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.
