Shark cordless not working: power and roller fixes

If it will not power on

Work through these checks in order. Most Shark sticks that seem dead simply have a flat battery, a battery that is not fully clicked in, or a charger that is not delivering power.

1. 1

   Charge the battery fully, on or off the vacuum, and check the charge lights come on.

2. 2

   Remove the battery and click it back in firmly.

3. 3

   Try a different wall socket and check the charger cable for damage.

4. 4

   If you have a second battery, try it. If the vacuum works, the first battery is the problem.

5. 5

   Leave the vacuum to cool for an hour if it stopped after a long clean.

If the brush roll has stopped

A brush roll that stops while the motor runs usually means the roll is jammed or overloaded. Hair, string, carpet fibres or a sock can stall it. Many Shark heads stop the roll automatically to protect the motor.

Switch off and remove the battery, then turn the head over. Remove any debris, take the brush roll out if your model allows, and clear the ends. Check the head's neck for blockages. Refit and test on a hard floor first. Our brush bar cleaning guide shows how.

If lights are flashing

Shark uses light patterns on the handle or battery to signal faults such as a blockage, a brush roll jam, a battery fault or overheating. The meaning varies by model, so check the troubleshooting table in your manual or on Shark's website for your model code.

Some models show an error code instead. Note the code and the pattern before you call Shark, as it speeds up support. Our flashing lights explainer covers common patterns across brands.

Clear blockages and clean filters

Blockages and clogged filters cause many Shark faults, from cutting out to lost power. Empty the dust cup, check the cyclone for hair, look through the wand and check the neck of the floor head. Remove the filters, tap off loose dust and rinse them in cold water if your manual says they are washable.

Let filters dry completely, usually at least 24 hours, before refitting. Never run the vacuum without filters, as dust can damage the motor.

Flexology and connection faults

On Flexology models, the bending wand carries power to the floor head through contacts at each joint. If the head stops working but the handheld works, check the contacts for dirt and make sure each part clicks firmly into place. A damaged wand joint can stop power reaching the head.

Try the floor head directly on the handheld without the wand, if your model allows. If it works, the wand is the likely fault.

When to contact Shark

If none of these checks help, contact Shark UK with your model code and serial number. Shark's UK listings typically state a 5-year guarantee on registration, with a shorter term for batteries, so check whether your machine is still covered before paying for parts.

If the vacuum is old and several parts are failing, compare the cost of repair with a new machine. Our Shark comparison lists current models.

Keeping a Shark working well

Most of these faults can be prevented with a little routine care. Empty the dust cup after each clean, rinse the filters every few weeks, and lift the floor head to clear the brush roll ends once a month. Store the vacuum indoors at room temperature and avoid leaving the battery fully flat for weeks.

If you use an auto-empty dock, check the dock's own bin and its intake for blockages too. A blocked dock can stop the dust cup emptying properly, which leads to full-cup faults on the vacuum. Our self-emptying dock guide covers how docks work.

Frequently asked questions

Why has my Shark brush roll stopped spinning? Hair or debris has jammed it, or a blockage is overloading the head. Clear the roll and the head's neck.
