The recalled blowers have the words "TORO Power Sweep" written on another decal on the product, and a black impeller fan, which can be seen through the air inlet screen on the bottom of the unit.

A breath of fresh air will sweep through the halls of power, and those harbouring dark intentions will be replaced.
