The suction draws very well, at the suction power is nothing to complain about! strong, and no ejection of ash into the room! But ... the length of the power cord is an impertinence and insolence! Although the stove I have an outlet in about 1.5 meters, It is not possible to work without an extension cord. The vacuum cleaner is also extremely noisy at very high frequency. is the (also) too short a hose also Constantly the air blown in the face. So who still the same when you buy an extension cable, ear protection and perhaps mitkauft goggles and a dust mask, so that an exhaust air the one blows in the face does not interfere with the be absolutely satisfied with the device !! ;-) The vacuum cleaner is not enough !, really a pity! But when suction is the device not bad buy ... Device with Verbbesserungspotential !!
