Check the wire and plug

The electrical cord should remain untangled at all times. Tangled and kinked wires can cause problems, especially when an automatic wire recoil function is used. The plug should also be checked for damage as a bent or over-pulled plug can be hazardous due to exposed wiring and other elements. Be careful when using the cleaner not to run over the cord or flex with the moving brushes as damage may occur to the cleaner.
