Step 2: Check for Blockages

  • Detach the wand, cleaner head, and hose from the main body.
  • Visually inspect each for obstructions or debris.
  • Use a long, flexible brush or a straightened coat hanger to dislodge any blockages.

Remove the pre-filter and main filter. Rinse the filters thoroughly with water, ensuring they are completely dry before reinserting. If filters are damaged or excessively dirty, replace them with compatible new filters like the 3Pack Pre Filters Replacement or V10 Filters.

Step 4: Reassemble and Test

  1. Reattach all parts securely, ensuring no components are loose.
  2. Turn on your vacuum and test suction on a small area.

  • Do not use harsh chemicals or abrasive brushes on filters.
  • Regularly clean filters every 2-3 months for optimal performance.
  • Consult your user manual for specific filter replacement procedures.
