Query: Very useful pump

I bought this pump to remove water from the winter cover of my swimming pool. It did the job fatanstically. The only problem is the water suction attachment is very easy to suck and sealed with my plastic swimming pool cover. I need to put a flat plastic plate (a dustpan) beneath the sucking head. Other than that, the pump is really what I need and very robustic.
