Self-cleaning filter
The self-cleaning filter does not require manual cleaning and it always allows a constant aspiration. There is no need to worry about cleaning the clogged filter to ensure the effective vacuum cleaner operations (simply empty the dust collection drum every 15 days). We recommend replacing the filter every two or three years.

Classic Filter
The classic filter requires steady maintenance. Once a week, the drum must be emptied and the filter must be cleaned. We suggest the filter replacement every two or three years.
