Maintenance
Emptying the Dust Bin (Dry Vacuuming)
Empty the dust bin as soon as the dirt reaches the MAX level – do not overfill.

- Push the red bin release lever down firmly. The shroud will slide down, wiping the shroud and releasing the bin base.

Cleaning the Wet Roller Head
After each wet cleaning session, it is crucial to clean the wet roller head and empty the dirty water tank.
- Remove the wet roller head from the wand.
- Open the dirty water tank and dispose of the contents. Rinse the tank with clean water.
- Remove the roller brush from the head. Rinse the roller brush under running water until clean.
- Allow all components to air dry completely before reassembling.
Filter Maintenance
Your Dyson V12S is equipped with a HEPA filter. For optimal performance, wash the filter at least once a month, or more frequently if used heavily.
- Locate the filter on the top of the main body.
- Twist and pull to remove the filter.
- Wash the filter under cold running water until the water runs clear. Do not use detergents.
- Tap the filter gently to remove excess water.
- Leave the filter to dry completely for at least 24 hours in a warm, dry place. Do not dry in a tumble dryer, microwave, or near a naked flame.
- Ensure the filter is completely dry before replacing it in the machine.
