Not brought this one/set up but used and converted this vac ( branded differently ) it's a good basic system and your saving a few hundred over the "specialist suppliers" who basically supply the same thing.
Bear in mind it is basic - silicone swan neck - Ali poles so if you plan to vac 3 or 4 a day or 3 storey or commercial then you need serious kit "interceptor" but for 2 storey residential it's a good choice
