Clean or Replace the Filters
Clogged filters can cause the vacuum to overheat or pulsing to occur. Remove the pre-filters and main filters following the manufacturer’s instructions.
Wash the filters with water, ensuring they dry completely before reinstalling. Consider replacing filters if they are worn out or excessively dirty.
Allow the Vacuum to Cool
If the vacuum overheats, it may automatically pulse to prevent damage. After use, let the vacuum cool down for at least 30 minutes before resuming cleaning.
Ensure the vacuum is in a well-ventilated area during cooling.
Check Battery and Power Settings
- Ensure the battery is fully charged and properly connected.
- Switch between different power modes to see if the pulsing occurs only in certain modes.
- If the battery shows signs of aging or isn’t holding charge, consider replacing it.
Perform Regular Maintenance
Keep all components, including filters, brushes, and nozzles, clean and free of debris. Regular maintenance reduces the likelihood of pulsing caused by airflow restrictions or motor strain.
