Even after 1 application (dry eyes / dirt removal my lined with concrete gravel plates garden terrace and lined with smooth stone slabs doorway) I realized that the use of the paper filter bag is strongly recommended! Or you can take a relatively rapid contamination of the built-in metal filter and thus a strong decrease in suction power in purchasing. Consequence: In view of the significantly lower filling volume of the paper bag is the dry eyes the 30 liter capacity, the metal container only of theoretical significance!
Very disappointing, however, the effective suction power during dry eyes! The majority of on the terrace sporadically lying around leaves not coped with the dry cleaner. Similarly, virtually all remained unmoved mini Splittsteinchen are even on the smooth stone slabs!
My then testweise zoom drawn discarded residential vacuum cleaners managed all this much better! Reason: He has a suction capacity of 1,800 W - the dry cleaner, however only 1,150 W ... The wet cleaning of the Einhell sucker I have not yet tested this disappointment.
Conclusion: If I had the wet / dry vacuum is not already assembled and once in operation, I would have immediately made use of my right to return - and bought me a much stronger model.
