Reported Shark HZ250 Series Issues

What issue are you encountering?


  • My unit has no or low suction
    • Turn on the unit
  • The brush roll is not spinning
    • Ensure the unit is plugged in and turned on. Place your foot on the floor nozzle and tilt the handle back to engage the brushroll
        • What color is the Brushroll Indicator light?
          • No Light
            • Unplug the unit.
            • Using a coin, turn the locks counterclockwise on the bottom of the nozzle to open, then lift off cover to access Brushroll. Carefully remove any string or debris from the brushroll.
            • Replace cover, pressing down firmly on all sides, including along the front, before turning locks clockwise to close.
            • Using a flashlight look into the 3-hole connector on the end of the handheld for debris. Remove any debris.

            • Attach the hand vac directly to the nozzle, pressing firmly until you hear a “click”
            • Plug in the unit.  Press lightly on the floor nozzle and tilt the handle back to engage the brush roll.  Now turn on the unit
          • Solid/Flashing Red
            • Follow the below steps for Solid and Flashing red light.
            • Note: If the light is flashing red the motor in the nozzle may have overheated. Allow the unit to cool down for 60 minutes after Troubleshooting is done.
            • If the light turns red only happens on a particular carpet/rug, try using an accessory to clean these areas.
            • Note to agent: Please document what type of carpet in the notes (EX. Plush, level loop, shag, or multilevel)
            • Is the unit set to the correct setting?  Setting I should be used on bare floors and small area rugs while Setting II should be used on carpets. The unit has a safety feature to prevent the brush roll motor from overheating on thick carpet.
            • There could also be a clog in the nozzle.
            • Plug in and turn on the vacuum using Setting I – Bare Floors. Gently step on the footprint icon on the floor nozzle and tilt the vacuum handle back to engage the brush roll.
            • Run it back and forth across the floor
    • My unit will not turn on or turn off on its own
      • The vacuum cleaner is equipped with a motor-protective thermostat. If for some reason your vacuum overheats, the thermostat will automatically turn the unit off. Wait 60 minutes for the vacuum to cool. In the meantime, follow the steps below
      • Is power issue with the unit or brush roll?
        • Unit
          • Check the power cord for damage and the plug prongs for being loose
      • There is a burning smell
        • If the smell is the out-of-the-box unit, this may be a new motor smell for the first couple of uses.
        • Turn off and unplug the vacuum.
        • Inspect the power cord and plug for exposed wires, burns, or obvious damage
      • My unit is making an unusual noise
        • The sound of the vacuum is loud due to the motor position in the handheld (air rushing similar to an airplane). Check if the noise is pitchy and coming from the floor nozzle.
        • Turn off and unplug the vacuum.
        • Detach the floor nozzle from the handheld and extension wand.
        • Remove the dust cup by squeezing the dust cup release tabs on the bottom of the handheld and pull the dust cup out.
        • Holding it over a trash receptacle, press the release button near the top of the dust cup. With both hands, open the dust cup until it clicks open.

        • Clear away any debris from the cone-shaped metal screen inside the dust cup and close the lid.
        • Look in the handheld piece with a flashlight to determine if any debris is obstructing the openings/airways and remove any clogs.

        • Re-insert the dust cup into the handheld, ensuring each slide clicks into place.

        • Plug the unit in and turn it on
    • Warm Handheld Vacuum
      • The handheld can get warm after use around the filter exhaust area. Due to stronger suction power compared to other corded stick vacuums, this is normal to experience. Turn off the vacuum and wait for 10 minutes to cool it down. If the handheld is intolerably warm, call back again.
      • Turn off and unplug the vacuum.
      • Remove the handheld from the wand. Remove the filter grill from the top of the handheld and check for signs of melting plastic inside.
