Clean or Replace Filters

  1. Remove the pre-filters and filters from the vacuum.
  2. Rinse the filters under cold water until the water runs clear.
  3. Allow filters to air dry completely (at least 24 hours) before reinstalling.
  4. If filters are damaged or overly worn, replace them with compatible filters like the 3Pack Pre Filters Replacement.

Inspect Power and Battery Settings

Ensure the vacuum is fully charged. If the pulsing occurs during use, try switching power modes or resetting the vacuum:

  • Switch to a different power mode via the LCD screen.
  • Turn off the device, wait 10 seconds, then turn it back on.

Reset the Vacuum

  1. Turn off the vacuum and disconnect it from the charging dock.
  2. Remove the battery if possible, wait 30 seconds, then reattach.
  3. Power on and test for consistent operation.

Check Sensor and Debris Detection

Ensure the floor surface is clear and free of large debris. Avoid using the vacuum on overly uneven or reflective surfaces that might confuse sensors.
