When using an electrical appliance, basic precautions should always be followed, including the following:
• READ ALL INSTRUCTIONS BEFORE USING (THIS APPLIANCE).
• Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.
• Do not use outdoors or on wet surfaces when charging. Store indoors. Use indoor only.

• Do not handle power cord, including power cord plug, and power cord terminals with wet hands.
• Do not put any object into openings. Do not use with any opening blocked; keep free of dust, lint, hair, and anything that may reduce air flow.
• Do not immerse. Use only on carpet moistened by cleaning process.
• Brush may start unexpectedly. To reduce the risk of injury from moving parts, keep the power off before cleaning or servicing.
