Operating Instructions
1. Power Settings
The STV-3 features a powerful high-speed BLDC 500W motor with three suction power settings: low, medium, and high. Use the ergonomic button on the display screen to easily toggle between these levels for various cleaning tasks, from light floor cleaning to deep rug cleaning.
2. Dust Detection
The optical dust sensor detects debris. The screen will display "Dust Detected" when actively picking up dirt. When the screen illuminates green, no dust is detected, indicating the surface is clean.
3. Handheld Mode
The STV-3 easily converts into a handheld vacuum by detaching the wand. This mode is ideal for cleaning upholstery, car interiors, and other hard-to-reach areas using the appropriate accessories.
