3. Operating the Vacuum
The Shark PowerDetect features intelligent technologies to optimize your cleaning experience.
3.1 PowerDetect Intelligence
The vacuum automatically senses and adapts to your cleaning needs:
- Dirt Detect: Optimizes suction and runtime for efficient cleaning performance by detecting hidden dirt.
- Floor Detect: Automatically adapts to floor type (e.g., hardwood, carpet) by adjusting brushroll RPM.
- Edge Detect: Automatically adapts suction on corners and edges for a deeper clean.
- Light Detect: Automatically illuminates darker areas for improved visibility.

3.2 DuoClean Detect Nozzle
The redesigned DuoClean Detect nozzle features two brushrolls for effective cleaning on all floors and ultra-powerful hair pickup. It captures dirt, dust, and debris in both forward and reverse for faster cleaning.

5. Troubleshooting
If you encounter issues with your Shark PowerDetect vacuum, refer to the following common solutions:
- No Power: Ensure the battery is fully charged. Check the charging cable connection.
- Reduced Suction: Empty the dust cup. Clean all filters (pre-motor and post-motor HEPA). Check the nozzle and wand for blockages.
- Brushrolls Not Spinning: Ensure the nozzle is properly attached. Check for blockages in the brushroll area and clear any tangled hair or debris.
- Short Runtime: Ensure the battery is fully charged. Operating in BOOST mode will reduce runtime significantly compared to ECO mode.
