- Open the roller cover according to your vacuum cleaner's main instruction manual.
- Carefully remove the old cleaning roller, if present.

4. Operating with Accessories
Once the cleaning roller and sponge filter are installed, your Leifheit Regulus Aqua PowerVac is ready for operation. The accessories work in conjunction with the main unit to provide efficient cleaning.
- The cleaning roller actively scrubs and absorbs dirt from hard floors. Its 2-fibre system is designed to tackle various types of dirt, including stubborn residues.
- The sponge filter continuously protects the vacuum cleaner's motor by preventing dirt particles and water from entering the motor housing during operation.
- The cleaning brushes are used for post-operation maintenance, as detailed in the Maintenance section.
5. Maintenance
Regular maintenance of your accessories ensures optimal performance and extends the lifespan of your Leifheit Regulus Aqua PowerVac.
5.1. Cleaning the Cleaning Roller
- After each use, remove the cleaning roller from the vacuum cleaner.
- Rinse the roller thoroughly under running water until all dirt and debris are removed.
- For deeper cleaning, the roller can be washed with mild soap and water.
- Allow the cleaning roller to air dry completely before re-installing it or storing it. Ensure it is fully dry to prevent mildew or odors.
5.2. Cleaning the Sponge Filter
- Remove the sponge filter from its compartment.
- Rinse the filter under running water to remove accumulated dirt. Gently squeeze the filter to release trapped particles.
- Allow the filter to air dry completely before re-inserting it. A damp filter can damage the motor.
- Replacement: The sponge filter should be replaced regularly, typically every 3-6 months, or sooner if visible wear or reduced suction is observed. Regular replacement protects the motor and maintains cleaning efficiency.
5.3. Using the Cleaning Brushes
- Use the larger cleaning brush to clean the water tank and other accessible internal parts of the vacuum cleaner.
- The smaller, narrower brush is ideal for cleaning the suction channel and other tight spaces where dirt might accumulate.
- Rinse the brushes after use and allow them to air dry.
6. Troubleshooting
This section addresses common issues related to the accessory set. For problems with the main vacuum cleaner unit, refer to its dedicated instruction manual.
6.1. Cleaning Roller Not Spinning Effectively
- Check for Obstructions: Remove the roller and inspect for tangled hair, threads, or debris that might be preventing it from spinning freely. Clean as necessary.
- Improper Installation: Ensure the roller is correctly seated and locked into its compartment. Refer to Section 3.1.
- Wear and Tear: If the roller is old and worn, its cleaning effectiveness may diminish. Consider replacing it.
6.2. Reduced Suction Power
