UV3900 Series Shark® POWERDETECT™ Complete Performance Upright - FAQs

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 cleaning and odor neutralizer technology performance, clean filters regularly. Between cleanings, lightly tap filters over a trash receptacle to remove dust and debris as needed. Rinse the pre-motor foam and felt filters with cold water every month, or as needed. • Remove the dust cup to access the pre-motor filters. • Press the release button on top of the pod. Lift the dust cup up and away from the pod. • Remove the foam and felt filters from underneath the dust cup. • Rinse both filters with water only. • Allow filters to air-dry completely (at least 24 hours) before reinstalling. • Once the filters have dried, install the felt filter first, followed by the foam filter. • Reinstall the dust cup by placing the bottom of the dust cup into the pod and then tilting until it clicks into place. Rinse the post-motor HEPA filter with cold water every 12 months, or as needed. • With the dust cup removed, pull the tab on the bottom of the pod to release the HEPA filter cover. • Press the latch on the HEPA filter to remove the filter. • Rinse with water only. • Allow filter to air-dry completely (at least 24 hours) before reinstalling. • Once the HEPA filter has dried, reinstall it. • Reattach the HEPA filter cover until it clicks into place.

For optimal performance, empty the dust cup each time you vacuum, or when debris reaches the MAX FILL line. • Press the button on the top of the pod. Tilt the dust cup down, away from the wand, then pull it up and away from the pod. • Hold the dust cup over the trash. Push the button on the front, base of the dust cup to release debris. • Tap gently to empty contents. • Close the dust cup door by locking the door back into place. • If needed, turn the dust cup upside down over the trash and press the top release buttons by the dust cup handle. • Tap gently to remove contents. Clear debris from the cone-shaped screen. • To reinstall, place the bottom front of the dust cup into the pod, then tilt it back toward the wand until it clicks into place.

If any hair is wrapped around the brushroll, continue vacuuming, using Carpet Low Pile mode on a bare floor surface, a low-pile carpet, or a small area rug. This will allow the self-cleaning brushroll to remove the hair wrap and send it to the dust cup. If the issue persists: • Detach the pod from the nozzle by pressing the Powered Lift-Away® button on top of the dust cup handle. • Detach the wand from the nozzle and then place the nozzle on a flat surface, with the bottom facing up. • Using scissors, carefully remove any string, hair, or debris that may be wrapped around the brushroll. • Reattach the wand to the nozzle. Then slide the pod back onto the wand until it firmly clicks into place. Note: Do not vacuum wet messes.

Floor Detect identifies surface type and adjusts brushroll speed and suction for optimized cleaning. Maintenance: Make sure to clean the Floor Detect sensor regularly, as hair and other debris may build up and obstruct the sensors. If the sensor is partially obstructed, Floor Detect mode will not function as expected. To easily access the nozzle for sensor cleaning, step on the Lift-Away(R) pedal to detach the pod. Locate the Floor Detect sensor on the bottom of the nozzle. Use a cotton swab to wipe away dirt and debris from the sensor and surrounding area.

Edge Detect focuses and maximizes suction along corners and edges to target stubborn dirt. Maintenance: Make sure to clean the Edge Detect sensors regularly, as hair and other debris may build up and obstruct the sensors. If the sensor is partially obstructed, Edge Detect mode will not function as expected. To easily access the nozzle for sensor cleaning, step on the Lift-Away(R) pedal to detach the pod. Locate Edge Detect sensors on the sides of the nozzle (small clear ovals on the top, rear edge). Check the sensors, and remove any dirt or debris that may be blocking them. Gently wipe the sensors with a microfiber cloth, using a circular motion.

Dirt Detect identifies dirty areas and automatically boosts suction power to pull in hidden dirt. Maintenance: Make sure to clean the Detect sensors regularly, or when the Dirt Detect Indicator is red, as hair and other debris may build up and obstruct the sensors. If the sensors are partially obstructed, Detect mode will not function as expected. To easily access the nozzle for sensor cleaning, step on the Lift-Away(R) pedal to detach the pod. Turn the nozzle upside down and locate the nozzle inlet access point between the brushrolls and rear wheels. Pinch the nozzle hose inlet and pull open the door. Arrows indicate the two small Dirt Detect sensors. Gently wipe the sensors with a microfiber cloth and remove all hair and debris

This Shark® vacuum has four powerful settings for cleaning. The touchscreen selector is located right below the power button. Touchscreen Selector: To switch between modes, gently tap the desired mode icon Detect Mode: Select Detect mode to activate Smart Detect Technology. In this mode, the vacuum will detect floor type, dirt, and edges, and will automatically adjust suction to maximize cleaning performance. Manual Surface Modes: Select one of the manual surface modes (Hard Floor, Carpet/Low Pile, or Thick Carpet/Area Rug) to clean specific surfaces without Smart Detect Technology. To clean bare floors, tile, and low pile area rugs: • Press the power button and tilt the handle back while gently stepping on the floor nozzle. Note that the brushroll will spin slower in this mode. • On the CapTouch touchscreen selector, tap Hard Floor. Note: Use Hard Floor setting for maximum suction when cleaning above floors and for easier maneuverability on low pile area rugs. To clean low pile carpets: • Press the power button and tilt the handle back while gently stepping on the floor nozzle. Note that the brushroll will spin slower in this mode. • On the CapTouch touchscreen selector, tap Carpet/Low Pile. To clean thick carpets: • Press the power button and tilt the handle back while gently stepping on the floor nozzle. Note that the brushroll will spin slower in this mode. • On the CapTouch touchscreen selector, tap Thick Carpet/ Area Rug.

• Insert the wand into the nozzle. You should hear it "click" into place. • Place the pod onto the wand and slide it down until it clicks in place. • Insert the handle into the top of the wand. You should hear it "click" into place. • Connect the hose to the back of the pod. Ensure you hear a "click" before moving to the next step. • Remove the odor neutralizer technology dial from the bag. Flip up the dial handle, align the teal arrow on the dial with the teal arrow on the nozzle, then insert the dial into the nozzle. • Lock and engage the dial by rotating it counterclockwise until it clicks into the desired odor intensity setting. • Store included accessories on the accessory posts on the pod. For proper operation, ensure all parts are firmly clicked into place.

If you vacuum is pushing or lifting your area rug, press the power button to turn on the vacuum and select the Hard Floor mode. Note: The brushroll will spin slower in the Hard floor mode. If this issue persists, we recommend attaching the Upholstery Tool (with the bristle head removed) to the wand to clean these rugs.

To clean above-floor areas in Lift-Away® mode: • First release the power cord by turning the top cord hook downward. • Press the "Powered Lift-Away" button on the dust cup to detach the pod from the wand. • Lift off the pod by pulling up on the dust cup handle. • Detach the wand from the pod by pressing the wand release button. • To vacuum with the handle, press the release button to detach the handle from the top of the wand. • For more reach, reattach the handle to the wand. • You can attach a cleaning accessory to either the handle or the end of the wand.

Check to see which floor setting you are using. If you are using DETECT mode, try manually overriding for better maneuverability. For manual override on thicker carpet types, tap Thick Carpet/Area Rug. This setting reduces suction and should allow for easier use on carpet. If changing the floor setting doesn't help, try using Powered Lift-Away® mode.

If the Soft Roller doesn't eject when you slide the button forward, there may be some debris caught around the Soft Roller. Slide the button forward again. If the roller still won't eject, gently pull on the right corner of the roller while sliding the button forward again. This should eject the roller and dislodge any debris. Once the Soft Roller has been ejected, carefully remove any remaining hair or debris from the Soft Roller and its connection points in the nozzle. Once all debris has been removed, please reinsert the Soft Roller and try slide the access button forward again.

Solid White Lights: The brushrolls are spinning and the unit is working as intended. Solid Red Lights: There is a jam in the brushroll area. Turn off the vacuum and unplug it, then remove any blockages in the nozzle. Flashing Red Lights: The motorized floor nozzle is overheating. Turn off the vacuum, unplug is, and remove any blockages.

If you're using Detect mode when you experience this issue, change the setting to Thick Carpet/Area Rug mode setting as this is optimized to not stall on thicker carpets.

The odor dial cover needs to be installed for the vacuum to function properly. If you do not wish to use the odor neutralizer technology system, please follow the below steps: 1) Remove the odor dial from the nozzle. Flip up the handle and rotate the dial clockwise until the two teal arrows are aligned. Pull the handle to lift the dial out of the nozzle. 2) Remove the odor cartridge by rotating the cartridge counterclockwise in the dial housing and pull out the cartridge. 3) Install the dial cover back into the nozzle without the cartridge. Align the teal arrow on the dial cover with the teal arrow on the nozzle, then reinsert the dial cover into the nozzle. To lock, rotate the cover counterclockwise until it clicks into place. 4) Dispose of cartridge by dropping it in the trash.

Yes, odor neutralizer technology cartridges should be replaced every 6 months for optimal performance.

1. Remove the odor neutralizer technology dial from the bag. Flip up the dial handle, align the teal arrows, then insert the dial into the nozzle. 2. To lock and engage the dial, rotate it counterclockwise until it clicks into the desired odor intensity setting.

Detect mode allows you to use the vacuum with the full suite of Smart Detect Technology activated. In this mode, the vacuum will detect floor type, dirt, edges, direction, and will automatically adjust suction to maximize cleaning performance. We recommend using this most for best user experience.

The Dirt Detect indicator is located on the Floor nozzle. When it turns purple, this indicates that dirt is detected. The vacuum senses high levels of debris on the surface you are cleaning and will increase suction to pull in hidden debris. The sensors may detect dirt that you are not seeing and may stay purple longer than you may expect. This happens particularly on carpets and in high traffic areas or if the sensors are dirty, and does not affect the overall suction and cleaning performance of the unit. Note: Some carpets (old or worn out) may be prone to shedding. This may cause continuous dirt detect activation. Verify Dirt Detect on clean hard surface to ensure there is not issue with the sensor. How to clean the Dirt Detect Sensors: To easily access the nozzle for sensor cleaning, step on the Lift-Away(R) pedal to detach the pod from the nozzle. Turn the nozzle upside down and locate the nozzle inlet access point between the brushrolls and rear wheels. (Figure 1) Pinch the nozzle hose inlet and pull open the door. Arrows indicate the two small Dirt Detect Sensors. (Figure 2) Gently wipe the sensors with a microfiber cloth and remove all hair and debris. (Figure 3) You can view a video on how to clean all the sensors in the floor nozzle by going here. ** CE to link AZ4 Detect Sensor Maintenance Video **

Direction Detect senses cleaning direction and directs suction forward or reverse for optimized cleaning

Certain dry temperatures 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. In order to avoid this, we recommend moisturizing your hands and/or removing wool socks or sweaters prior to vacuuming.
