3.5 Filter cleaning system DUSTOP
When the orange indicator light is on, or the suction efficiency has lowered, or after having
vacuumed a considerable quantity of material, a filter cleaning cycle is necessary. The filter
cleaning system is best operated every time before use and after prolonged operation.
➢ First of all, disconnect all the accessories (flex hose, hose connector, etc.) from the vacuum
cleaner.
➢ Turn on both motors and then proceed to close the suction inlet with the cap attached to
the suction inlet itself, assuring that there is no air flow through the filtering chamber.
