Maintaining your BOSCH 12-25 Professional Wet-Dry Extractor's optimal performance requires regular filter cleaning. Here's a step-by-step guide: Cleaning the Pre-filter: Open the catches and remove the vacuum cleaner's top. Take the pre-filter out by its handle and shake it over a waste bin to remove dust. Reinsert the pre-filter, ensuring the arrow aligns with the hose connection. Secure the top back on, closing the catches. Cleaning the Main Filter: Open the catches and remove the top. Rotate the filter holder fully and remove it with the main filter. Use a soft brush to clean the filter's folds; replace if damaged. Reinstall the filter holder, turning it fully. Replace the top and close the catches. Cleaning the Wet Filter: Open the catches and remove the top. Remove the wet filter from the filter basket. Rinse it under running water and let it completely dry. Place the dry wet filter back in the basket. Secure the top, closing the catches. Removing/Changing the Filter: Rotate the filter holder fully and remove it. Take out the main filter from the holder. Clean the main filter's folds with a soft brush or replace it if it's damaged. Place the filter holder with the main filter back, rotating it fully. Reattach the top, closing the catches. Consistent filter cleaning will help your BOSCH 12-25 Professional Wet-Dry Extractor maintain its suction power and extend its lifespan.
