Abstract
Vacuum cleaning apparatus having a rotary brush situated at an air intake opening in a housing has a configuration which enables efficient cleaning of edge portions of a floor that are adjacent to a wall or other vertical surface. A cleaning head portion of the housing has intersecting sidewalls which extend at right angles to each other enabling one sidewall to face the edge of a floor while the other sidewall faces the lower edge of an adjacent wall. The air intake opening is angled to extend into both of the angled intersecting sidewalls of the cleaning head. The rotary brush carries bristles which protrude through the air intake opening at both of the sidewalls of the cleaning head and at the intersection between the sidewalls.
