We've had the Milwaukee pump for a while now. It pumps great. We ran something through the pump once that made the factory impeller soft and it wouldn't pump. Bought a new after-market impeller from Amazon advertised as able to stand up to anything. So far it has. I'd recommend getting a spare impeller and keeping it on the parts shelf somewhere. They're not terribly expensive.

It would be a nice feature if they added the ability to start/stop the pump via cellphone so you didn't have to be at the pump itself to turn it on or off.
