- Power On: Plug the power cord into a grounded electrical outlet. Press the power button on the unit. The indicator light will illuminate (often orange or yellow) to show it is heating.
- Wait for Heating: Allow the unit to heat up until the indicator light changes color (often green) or turns off, indicating it's ready to produce steam. This typically takes a few minutes.
Operating Instructions
Once the unit is ready, you can begin cleaning:
- Steam Activation: Press and hold the trigger on the steam hose handle to release steam. For continuous steam, some models may have a lock feature on the trigger.
- Cleaning Surfaces:
- Windows/Glass: Attach the window squeegee. Apply steam while moving the squeegee across the glass surface. Wipe away excess moisture with a clean cloth.
- Floors: Attach the floor brush with a microfiber pad. Use extension wands for comfortable reach. Move the brush across the floor surface while applying steam.
- Grout/Tight Spaces: Use the detail nozzle with a nylon or brass utility brush. Apply steam directly to the grout lines or tight areas and scrub as needed.
- Fabric/Upholstery: Use the fabric steamer attachment, optionally with a microfiber bonnet. Hold the attachment a few inches from the fabric and apply steam in sweeping motions.
- Post-Cleaning: After steaming, wipe the cleaned surface with a clean, dry cloth to remove any loosened dirt or moisture.
Maintenance
Regular maintenance ensures optimal performance and longevity of your steam cleaner:
- Empty Water Tank: After each use, ensure the unit is cool and depressurized. Unscrew the cap and carefully empty any remaining water from the tank.
- Clean Accessories: Wash microfiber pads and bonnets after each use. Clean utility brushes and nozzles to remove any residue.
- Storage: Store the steam cleaner and its accessories in a cool, dry place. Utilize the cord storage on the bottom of the unit for neat organization.
- Descaling: If you notice reduced steam output or mineral buildup, descaling may be necessary. Consult the full product manual for specific descaling instructions, typically involving a vinegar solution.
