So here's the deal for anyone else interested. ..
They only make the strainer for the dc6000 and they will not sell you one to protect your pump. Also they have no idea what you're talking about unless you refer to it as a "cover". It turns out they do say this on the description of the product but long, loooong after their updates. The "hose" connector is different and nearly useless for the dc12000 as the interchangeable pieces shown in the picture as well. The one they send for the dc12000 is one you cut to size. So if you buy this pump, buy it for the pump and plan to get your own fittings.
