3.3 Charging the Battery

4. Operating Instructions
4.1 Powering On/Off
Press the power button on the LED display to turn the vacuum on or off.
4.2 Cleaning Modes and Detection Technologies
The Shark Detect Pro automatically adjusts suction and brushroll speed based on detected conditions:
- DirtDetect: When the vacuum senses high concentrations of dirt, the LED rings will turn red, and suction power will automatically boost. As the area becomes clean, the rings will change to orange, then blue.
- EdgeDetect: When cleaning along edges and corners, the vacuum increases suction power to ensure thorough cleaning in these hard-to-reach areas.
- FloorDetect: The vacuum intelligently identifies whether you are cleaning hard floors or carpets and adjusts the PowerFins brushroll speed accordingly for optimal performance.
