I have this stove sucker now today emptied for several weeks in operation and have him for the first time, so it is now time for this review. The first vacuum cleaner arrived damaged. Of the plastic versions for rotational feet one was broken. I complained about this and get a replacement before returning the defective unit after two days. The new device was safe and works perfectly. The suction power - that's the most important thing - is undiminished even after weeks and full tank. Without the filter would be blocked even once, I can always reliably suck the fireplace ashes. As the ashes sometimes still consist of "cinders", I recommend to start at the rear of the suction and to crush the metal tube case, the coarser, lying in front pieces by applying slight pressure in advance. This prevents large pieces to be sucked, then remain stuck in the intake manifold. But that does not, as you insert the tube into another hole and then to "bubbles" can. All the dirt is then out again (just make out!). The noise is bearable. Therefore, the vacuum cleaner fully meets its purpose and can be recommended without reservation. Esp. over those described in other products clogged filter after a short period of use, I can not complain! Even if the device in the first hour of operation strong Gerücke unfolded (airing or even longer period of time run out), I therefore give full 5 stars.
