The ornamental design for a vacuum cleaner, as shown and described.

The broken line showing of the remainder of the vacuum cleaner is for illustrative purposes only and forms no part of the claimed design. The contrast in shading techniques represents a contrast in color, with the line shading further representing translucency and the stippling further representing an opaque appearance.
