When the suction power starts to drop due to excessive dust load, this is indicated by the red warning light – replace the pre-filter. Before changing the filter, make sure that the outlet is free when the warning light is lit. If the suction power is still weak after pre-filter replacement, replace the HEPA filter. In case of heavy dust load, the service life is shorter.
