Sears Canada says it has been advised by Hoover Inc. of a potential safety hazard relating to certain WindTunnel Bagless Canister Vacuums. It has been discovered that the power cord between the powered nozzle and the wand can short-circuit posing a fire and shock hazard. This can occur even if the vacuum has been turned off but left plugged in. The silver coloured vacuums were sold through Sears Canada retail stores, online at www.sears.ca, and through the Sears Canada catalogue between January 2007 and December 2010. The affected model number is S3755. CNW Release
