6. Operating Instructions
The pitcher rinser operates with a simple push-down mechanism, utilizing water pressure to clean cups and pitchers effectively.
Operation Steps:
- Position the Cup: Invert the cup or pitcher and place its mouth downward over the rinser's star-shaped base.
- Activate Rinsing: Gently press the bottom of the cup onto the star-shaped base. This action will activate the multi-angle water jets, spraying water into the cup for cleaning.
- Rinse Thoroughly: Allow the water to spray until the cup is clean. The high-pressure washing saves time, water, and energy.
- Deactivate Rinsing: Lift the cup from the rinser. The water spray will automatically stop.
