5. Operating Instructions
The Kärcher SV 7 offers both steam cleaning and vacuuming functionalities, which can be used independently or simultaneously.
General Operation:
- Power On: Press the main power button. The appliance will begin heating the water to generate steam. An indicator light will show when the steam is ready.
- Steam Function: Press the steam trigger on the handle to release steam. Adjust steam intensity if applicable.
- Vacuum Function: Activate the vacuum function using the switch on the handle. The vacuum can be used for dry suction or to pick up moisture after steam cleaning.
Cleaning Different Surfaces:
- Hard Floors (Tiles, Linoleum): Use the floor nozzle with the squeegee insert. Vacuum loose dirt first, then apply steam while simultaneously vacuuming the moisture. This leaves floors clean and nearly dry.
- Carpets and Rugs: Use the floor nozzle with the brush insert. For deep cleaning, vacuum the carpet thoroughly, then apply steam in short bursts while moving the nozzle slowly. The vacuum will extract the moisture and loosened dirt.
- Upholstery and Fabrics: Use the upholstery nozzle. Test on an inconspicuous area first. Apply steam sparingly and vacuum immediately. Do not oversaturate fabrics.
- Windows and Mirrors: Use the window nozzle (if included) or the hand nozzle with a microfiber cloth. Steam the surface, then use the squeegee to remove moisture.
