This article contains the FAQs for the WV401 Series Shark® WANDVAC® POWER PET Cordless Hand Vac. This supports the following product SKUs WV401, WV401BL, and WV401PL.

How do I insert/remove the battery?

To insert, slide the battery into the opening in the handle of the hand vacuum. To remove, press the release tabs on the sides of the battery cap and slide out the battery.

How do I charge my vacuum?

You can charge your Shark® vacuum by placing it on the charging dock. Make sure the charging port near the nozzle opening is properly aligned with the contact pegs on the charging dock. The battery should take approximately 3.5 hours to reach a full charge.

How long will the battery run, and will I ever need to replace it?

Like all lithium-ion products, your battery will naturally decrease in capacity over time from the 100% capacity of a new battery. At full charge, the unit will run for 20 minutes in Deep Clean mode, 8 minutes in Boost mode, and 35 minutes in ECO mode.
These runtimes are based on 100% capacity.

Do I have to wait for my battery to fully discharge before I can charge it again?

You do not have to wait for your battery to fully discharge before you can charge it again.
It is recommended that you leave your vacuum on the charging dock after each use to recharge the battery completely. For optimal runtime, always return your vacuum to the dock after each use.

The battery has low runtime. What should I do?

The initial battery charge is approximately 30%. Before first use, charge the battery completely. A full charge takes approximately 3.5 hours.
Note that battery runtime is affected by the mode used. Vacuuming in Boost mode will reduce battery runtime quicker than vacuuming in ECO or Deep Clean Mode.
If you have more than one battery, it is recommended that you use and charge them equally.
It is recommended that you leave your vacuum on the charging dock after each use to recharge the battery completely.
Note: If the runtime is below 3 minutes in any mode, please empty the dust cup, remove any clogs from the nozzle, and clean the filters .

When and how do I clean the filters?

Filters may need to be cleaned if the vacuum stops picking up dirt, if airflow is restricted, or if you notice lighter or no suction. For optimal performance, clean filters regularly. Between cleanings, lightly tap filters over a trash receptacle to remove dust and debris as needed.
Rinse the fabric filter and the dust cup once monthly, or as needed.
• With the dust cup open to 90 °, pull up on the side tabs to tilt up the filter housing.
• Remove the fabric filter by pulling the wire handle.
• Tap the fabric filter clean.
• Rinse the fabric filter with soap and water only.
• Allow the fabric filter to air-dry completely (at least 24 hours) before reinstalling.
• Reinstall the fabric filter by sliding it back into the mesh filter. Press the filter housing back into place, then close the dust cup.
Note: After rinsing the filter, wait at least 24 hours before reinstalling it to ensure it is completely dry. A moist filter can damage the electronics of the unit and will void your warranty.

When and how do I empty the dust cup?

For optimal performance, empty the dust cup each time you vacuum.
• With the power switch off and the hand vacuum positioned over a trash can, slide the dust cup release button (on the bottom of the vacuum) towards you. The dust cup door will drop open.
• Tap gently to empty contents.
• Wipe the dust cup and the filter housing inside lightly with a dry cloth to remove dust and dirt.
• Close the dust cup door, pressing it until it clicks into place.

How do I use the different cleaning modes?

This Shark® vacuum has three power settings. Press the power button to enter Deep Clean mode by default. Press the Boost mode button for a burst of suction power, and press the ECO mode button to conserve power. Press the Boost or ECO mode button again to return to Deep Clean mode.

How do I find the model number of my WANDVAC® vacuum?

The model number is displayed on the vacuum’s rating label, which can be found behind the mesh filter inside the dust cup.

How and when do I adjust the suction?

Use Deep Clean mode for regular cleaning, Boost mode for an extra burst of suction power, and ECO mode to preserve power.
Press the Boost button to enter Boost mode. To return to Deep Clean mode, press the Boost button again.
Press the ECO button to enter ECO mode. To return to Deep Clean mode, press the ECO button again.

What happens if I experience small static shocks while vacuuming?

Certain dry conditions in winter or dry desert areas may cause common static electricity to build up in the vacuum, producing small shocks, similar to what you might experience from contact with doorknobs, wool sweaters, or blankets. This is harmless. To avoid this, we recommend moisturizing your hands and/or removing wool socks or sweaters prior to vacuuming and/or running a humidifier.

What should I do if my vacuum is not picking up dirt or debris?

Filters may need to be cleaned if the vacuum stops picking up dirt, if airflow is restricted, or if you notice lighter or no suction. For optimal performance, clean filters regularly. Between cleanings, lightly tap filters over a trash receptacle to remove dust and debris as needed.
• With the power switch off and the hand vacuum positioned over a trash can, slide the dust cup release button (on the bottom of the vacuum) towards you. The dust cup door will drop open.
• Tap gently to empty contents.
• Wipe the mesh filter inside and the dust cup lightly with a dry cloth to remove dust and dirt.
• Tilt the mesh filter up and remove the fabric filter by pulling on the wire handle.
• Tap the fabric filter clean.
• Reinstall the fabric filter by sliding it back into the mesh filter. Press the mesh filter back into place.
• Close the dust cup door, pressing it until it clicks into place.

Why is the dock unstable?

Before use, assemble the charging dock by attaching the accessory stand. Make sure the charging cord fits in the groove on the bottom of the dock and accessory stand. If the cord is not fully inserted in the groove, the dock could be unstable.

What if the battery is warm to the touch or indicates that it's too warm to charge?

Your battery may feel warm in use as air passes through the vacuum. If it feels uncomfortably warm, stop using the vacuum and allow the battery to cool. If the battery continues to feel warm or the power button light on the displays an error message (as outlined in the Owner's Guide), contact Customer Service at 1-800-798-7398 or sharkclean.com/support.
Batteries can get warm from use, which is not optimal for charging. When this occurs, the charging dock will wait for the battery to cool before it begins charging.

How do I store my vacuum?

Store the handheld vacuum by inserting the nozzle into the charging dock. When the nozzle is inserted correctly, the power button will illuminate and blink steadily.
It is recommended that you leave your vacuum on the charging dock after each use to recharge the battery completely. For optimal runtime, always return your vacuum to the dock after each use.

How do I attach and remove accessories?

Attach an accessory to the nozzle opening in the hand vacuum and begin cleaning. To detach an accessory from the hand vacuum, slide it off the nozzle.

What should I do if the vacuum doesn't turn on?

Make sure the unit is fully charged. If the charge is low, the Power button light will blink before the vacuum powers down. Confirm that the unit is charging by placing the vacuum on the charging dock. The Power button light will pulse slowly to indicate charging has begun.
This unit is equipped with a motor-protective thermostat. If for some reason your vacuum overheats, the thermostat will automatically turn the unit off. Overheating is indicated by the Power button light blinking 6 times in 2-second intervals. Typically, overheating is caused by a clogged airway. It may take approximately 45 minutes for the unit to cool. Perform the following steps to clear the clog while the vacuum cools.
1. Empty the dust cup.
2. With the power switch off and the hand vacuum positioned over a trash can, slide the dust cup release button (on the bottom of the vacuum) towards you. The dust cup door will drop open.
3. Tap gently to empty contents.
4. Close the dust cup door, pressing it until it clicks into place.
5. Inspect the inside of the nozzle and clear any blockages.
6. Place the unit on the dock. Charging will automatically begin once the unit has cooled down (about 45 minutes).
If problem persists, please contact Customer Service at 1-877-581-7375.
