Shark robot vacuum spinning in circles then stopping
I've got a Shark robot vacuum that's 2 years old and it just turns in circles and stops with an error. Really hoping it's a cheap fix.

If a Shark robot vacuum just spins in circles and then errors, the most common causes are a wheel/bumper problem, dirty sensors, or the side brush jamming the navigation. Hopefully it is something simple.
1. Fully power it down and clean it Remove the robot from the dock and switch it off if your model has a power switch. Clean the underside thoroughly, especially: - Front castor wheel - Drive wheels - Side brush - Cliff sensors - Front bumper edge Hair and fluff around the wheels or castor can make it think it is stuck and cause circling.
2. Check both drive wheels Spin each wheel by hand. They should both turn with similar resistance and spring up and down freely. If one wheel is stiff, jammed, or not dropping back properly, that can make it turn in circles.
3. Check the front castor wheel Pop it out if possible and remove hair/thread from the spindle. A seized or dragging castor is a very common cheap fix on robot vacuums.
4. Remove the side brush temporarily Run it briefly without the side brush fitted. If the brush is bent, catching, or its motor is struggling, it can upset the robot’s movement.
5. Inspect the bumper Press the bumper in and let it spring back. If it is sticking on one side, the robot may think it has hit something and keep turning.
6. Try a reset and fresh start Charge it fully, reset it as per the manual/app, and test it in a clear open area.
Safety reminder: isolate the appliance from the mains before inspecting internal parts. If a wheel motor, sensor board, or internal wiring has failed, it will likely need a qualified engineer, especially for any mains-related repairs.

Safety first — read before actioning advice
Never work on a live appliance
Always unplug it at the mains before going near it with any tools.
Never attempt gas work
By law, gas appliances must only be worked on by a Gas Safe registered engineer. If your fault involves gas, stop and call a professional — do not attempt it yourself.
Watch for sharp edges
Outer panels are smooth, but internal parts are full of sharp machined edges. Wear protective gloves and arm sleeves.
Water appliances can leak
Turn off the water supply before disconnecting any hoses.
Know your limits
If you're not confident testing or working inside the appliance, STOP and call a professional.
