Important Safety Information
When using an electrical appliance, basic precautions should always be observed, including the following:
- Read all instructions before using this vacuum cleaner.
- Do not use outdoors or on wet surfaces.
- Do not allow to be used as a toy. Close attention is necessary when used by or near children.
- Use only as described in this manual. Use only manufacturer’s recommended attachments.
- Do not use with a damaged cord or plug. If appliance is not working as it should, has been dropped, damaged, left outdoors, or dropped into water, return it to SharkNinja Operating LLC for examination, repair, or adjustment.
- Do not pull or carry by cord, use cord as a handle, close a door on cord, or pull cord around sharp edges or corners. Do not run appliance over cord. Keep cord away from heated surfaces.
- Do not unplug by pulling on cord. To unplug, grasp the plug, not the cord.
- Do not handle plug or vacuum cleaner with wet hands.
- Do not put any object into openings. Do not use with any opening blocked; keep free of dust, lint, hair, and anything that may reduce airflow.
- Keep hair, loose clothing, fingers, and all parts of body away from openings and moving parts.
- Turn off all controls before unplugging.
- Use extra care when cleaning on stairs.
- Do not use to pick up flammable or combustible liquids, such as gasoline, or use in areas where they may be present.
- Do not pick up anything that is burning or smoking, such as cigarettes, matches, or hot ashes.
- Do not use without dust cup and/or filters in place.
- Prevent unintentional starting. Ensure the switch is in the OFF-position before connecting to battery pack, picking up or carrying the appliance.
- Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.
- Use appliances only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.
- When battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws or other small metal objects, that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.
- Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.

Operating Your Vacuum
Power and Suction Modes
The vacuum features an LED display for real-time readouts, allowing you to monitor battery life, select suction levels, and engage Clean Sense IQ.
- Power On/Off: Press the power button on the handheld unit to turn the vacuum on or off.
- Suction Levels: Toggle between different suction modes (e.g., ECO mode for extended runtime, Boost mode for maximum suction) using the controls on the LED display.
Clean Sense IQ Technology
The infrared sensor detects dirt you cannot see and automatically increases power for up to 50% better dirt pickup. The Clean Sense IQ indicator visually shows when floors are clean.

Cleaning Filters
The vacuum features HEPA filtration and Anti-Allergen Complete Seal technology, capturing over 99.9% of dust and allergens. Filters should be cleaned regularly to maintain suction power.
- Pre-Motor Filters (Foam & Felt): Rinse every month. Tap loose dirt off between washes.
- Post-Motor HEPA Filter: Rinse once a year.
Allow all filters to air-dry completely for at least 24 hours before reinstalling them to prevent moisture damage to electronic components.
Brushroll Maintenance
While the DuoClean PowerFins HairPro features a self-cleaning brushroll, it is recommended to periodically check the brushroll for any tangled hair or debris and remove as necessary.
Troubleshooting
If you encounter issues with your Shark Stratos Cordless Vacuum, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Vacuum not turning on | Battery not charged or not properly inserted. | Ensure battery is fully charged and securely clicked into place. |
| Loss of suction | Dust cup full; filters clogged; blockage in nozzle, wand, or hose. | Empty dust cup. Clean pre-motor and post-motor filters. Check for and clear any blockages. |
| Brushroll not spinning | Blockage in brushroll; floor nozzle not properly connected; vacuum in wrong mode. | Remove any obstructions from the brushroll. Ensure floor nozzle is securely attached. Check that the vacuum is not in a mode that disables the brushroll (if applicable). |
| Short runtime | Battery not fully charged; using Boost mode excessively. | Fully charge the battery. Use ECO mode for longer runtime. Consider purchasing an additional battery for extended cleaning sessions. |
