- Remove the cleaner head and check for debris or tangled hair in the brush bar or nozzle.

Consider replacing filters if they are worn or overly dirty, using compatible replacements like the 3Pack Pre Filters or V10 Filters.

- Press the power button or trigger to reset the vacuum; some models may require a complete power cycle.
Perform Maintenance and Preventative Checks
- Regularly wash filters and clean the brush bar.
