Clean Sense IQ Technology

DuoClean PowerFins HairPro Nozzle

Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your SHARK Stratos vacuum.
Emptying the Dust Cup
Empty the dust cup after each use or when debris reaches the MAX FILL line. To empty, detach the handheld vacuum, position the dust cup over a trash bin, and press the release latch to open the bottom flap.
Cleaning Filters
The vacuum features an Anti-Allergen Complete Seal with True HEPA Filtration system. Regularly clean the pre-motor filters (foam and felt) and the post-motor HEPA filter according to the instructions in the full product manual. Rinse filters with cold water only and allow them to air dry completely for at least 24 hours before reinstalling.

Cleaning the Brushrolls
The DuoClean PowerFins HairPro brushroll is designed to be self-cleaning and minimize hair wrap. However, periodically inspect the brushrolls for any trapped debris or hair and remove as necessary. Refer to the full product manual for detailed instructions on accessing and cleaning the brushrolls.
Troubleshooting
If your vacuum is not performing as expected, consult the following common issues and solutions:
- Vacuum not picking up debris: Check the dust cup for fullness, ensure filters are clean and properly installed, and inspect the nozzle and wand for blockages.
- Brushrolls not spinning: Ensure the vacuum is powered on and in an appropriate mode for the floor type. Check for obstructions in the nozzle.
- Vacuum shuts off: This may indicate overheating. Turn off the vacuum, clear any blockages, clean filters, and allow it to cool for at least 60 minutes before restarting.
- Battery not charging: Ensure the charger is properly connected to both the battery/vacuum and a working power outlet. Check for any damage to the charger or battery.
