Step 2: Inspect and Clean the Filters
Clogged filters can impair airflow, making the motor work harder and draining the battery faster. Remove the pre-filters and main filters, rinse them under water, and allow them to air dry completely before reinstalling.
Step 3: Clear Blockages and Clean the Vacuum
- Check the wand, cleaner heads, and hose for blockages or debris.
- Use a soft cloth or a crevice tool to remove dust or hair buildup.
- Ensure all parts are dry and free of obstructions before reassembling.
Step 4: Replace Worn or Old Filters
If filters are over 2-3 months old or visibly dirty after cleaning, replace them with compatible filters like the 3Pack Pre Filters or V10 Filters. This restores suction and battery efficiency.
Additional Tips and Warnings
- Always use genuine or compatible replacement filters to avoid damage.
- Avoid overcharging the vacuum to prolong battery life.
- Do not attempt to open the battery pack yourself, as it may be hazardous.
