Operating Instructions
- Initiate Steam: Once the mop is heated (indicator light on), pump the handle a few times to initiate steam. The S3550 features on-demand variable steam, activated by your natural mopping motion.
- Begin Mopping: Move the steam mop across your hard floor surfaces in a forward and backward motion. The super-heated steam will clean and sanitize as you move.

- Double-Sided Cleaning: The Shark Steam Pocket technology allows for double-sided cleaning. When one side of the microfiber pad becomes soiled, simply flip the mop head to use the clean side of the pad, effectively doubling your cleaning area.

Maintenance
Regular maintenance ensures the longevity and optimal performance of your Shark Steam Pocket Mop.
- Cleaning Pads: The microfiber cleaning pads are washable. Remove them from the mop head after each use and machine wash with liquid detergent. Do not use bleach or fabric softeners, as these can damage the fibers. Air dry or tumble dry on low.
- Water Tank: After each use, empty any remaining water from the tank. For long-term storage, ensure the tank is completely dry.
- Descaling: Over time, mineral deposits may build up in the water tank and internal components, especially if tap water is used. To descale, fill the tank with a solution of one part white vinegar to two parts distilled water. Run the mop until the tank is empty. Repeat if necessary. Perform this monthly or as needed based on water hardness.
- Exterior Cleaning: Wipe the exterior of the steam mop with a damp cloth. Do not use abrasive cleaners.
- Storage: Store the steam mop in a cool, dry place. Ensure the cord is neatly wrapped.
