Abstract
A vacuum cleaner provides a jet of high velocity air into debris resting along a floor edge. The jet of air is aimed down and to the side of the vacuum cleaner vacuum head. The jet of air dislodges the debris urging the debris into the path of the vacuum head. The jet of air is conveniently created from the vacuum cleaner exhaust, and a left or right jet may be manually selected, or automatically selected by a wall detection sensor.
