We use the sucker now since half a year, and I honestly try the number of uses to keep in check and I also do not think the cleaning intervals of the filter (after each use). It sucks the ash properly, makes up a hell of a noise and the subsequent emptying should only be done with no wind and is trotzem still connected to the risk of getting einzuaschen completely. Because I would never suck the fireplace when still glowing embers in it, I wonder if we are for the ashes not prefer a cheap vacuum cleaners as the Fakir 1800 should have bought. De would still be more expensive, especially in terms of bags, but it has the at least one bag, I could then dispose clean.
