Today the DC 51 has been delivered. Even when assembling it hakelte here and there, particularly as regards the construction of Saurohres / hose / handle - this excess plastic feeling I did not at the DC 15. Short back and he pushed. It turns and twists unpleasantly. The hose including suction pipe is too short for a normal ceiling height. It raises then the sucker with. That was enough for me actually.
I have the part not even turned on - going back tomorrow.
My Conclusion: By comparing the DC 15 my criticism is unfortunately so. Even a price of 150 euros would be required, in my view too much. The concept is still okay, but the implementation ... shame.
PS: I have bought this DC 51 through Warehouse Deals. That ever was at the customer's okay so far, but that is in the dust container Situated sucked ... I do not know.
