A hand held, battery powered vacuum cleaner has a sealed light compartment over the vacuum opening with a lens that directs a light beam onto the plane of the surface being cleaned at least as close to the nozzle as one inch. The light chamber is smoothly integrated into the top of the nozzle so that the nozzle may illuminate and clean in spaces having low vertical clearance.
