Pretty good, but not a bestseller

I have un ago bought this sucker after much back as it was touted as a bestseller here. However, I must say I was not quite as enthusiastic. Phillips had previously a sucker that I was actually quite excited. But I did not want Phillips more, since the parts it break fairly quickly and so performance was but top.
I thought with a Siemens, plus declared bestseller, I could not do much wrong.

But let's start with the with important advantages:
We -air upward blown (ie fluff etc. are not spun, small children and animals is not blowing)
-Saugerluft Does not stink, as with other vacuums
IPMENT is easy
-Price Is extremely cheap for a "brand" unit
-Saugerbeutel Is relatively large
-All Makes a relatively stable impression (use it now but only just under 4 weeks)

In my opinion, the disadvantages:
-Low Suction. For a 170sqm budget with baby, toddler and two dogs the device brings too little power (and I had many suckers for comparison). I have to constantly suck on the same places, so that everything is absorbed. This is pulled slightly to the side, do not exist here. In addition, the suction cups at the end is always so hot that I think every time now he is determined broken. I use it now, therefore, only for the basement.
-Schwierig To handle, such as feeding the cable (it has never drawn immediately and at a time as I would like but the simple push back), telescopic pole extension is quite difficult up for it and this is the second to be mentioned negative factor ...
-... Plastic hose end (no idea what this is called partial ;-)) dissolves more of the telescopic rod
Cable for a big house too short (did not know what size we need, but the thought must have fit :-()
-very loud
