    • If the LED lights differ from the image below, go to LED Error codes when powered on

 

  • My vacuum will not charge
    • Note: Using a different brand charger can harm your vacuum and to avoid that, we recommend that you use the Shark charger that came with your vacuum.
    • Plug the charger in an outlet, where an appliance is plugged in and working (a verified working outlet), and place the vacuum on the charger.

  • What error code are you encountering?

    • Turn off the vacuum. Disassemble the unit. Remove the handheld vacuum from the wand, and the wand from the floor nozzle.
    • Inspect the connection points on a handheld for debris, damage, or burns
  • My unit is making an unusual noise
    • Note: The lower power modes (ex: Bare Floor ECO or Deep Clean) are significantly less noisy. Boost mode specifically is noisy due to the high power. Remove the handheld vacuum from the wand. Turn on the handheld

  • My unit has a short runtime
    • To get the most runtime, ensure that the battery is fully charged before use.
    • The battery runtime is affected by the mode you are using. If you have more than one battery, it is recommended that you use each equally in use and charging.
    • Compare runtimes to the chart below:

  • There is a bad smell coming from the vacuum exhaust
    • First, check the dust cup as it may be full; empty the dust cup if needed.
  • My vacuum is not evacuating into the dock
    • Ensure that the dock is plugged into a verified working outlet.
    • Place the vacuum on the dock in a downward motion. Once properly attached, you will hear the chimes that come before evacuation begins.
  • The brush roll is not self-cleaning
    • Hair that wraps or accumulates around the brush roll will automatically be removed as the brush roll continues to spin.
    • Ensure the nozzle, wand, and handheld are assembled. Turn the unit on and use the nozzle on the carpet for 1-2 minutes to allow the hair to naturally come off of the brush roll.
    • Turn the handheld off, remove the nozzle from the wand, and flip the nozzle over to look at the brush roll
  • How to remove and clean the dust cup and cyclone
    • With the dust cup door open, eject the dust cup from the handheld body by pressing the “Clean Filter Monthly” button. Remove the orange filter and tap to clear away debris.

       

    • Use force to push the black filter housing away from the clear plastic dust cup until it reaches a 90-degree angle. You will hear an audible click. Remove the cyclone by gently pulling the wire handle on the cyclone frame. Tap it over the trash to remove any excess debris.
