Emptying a 5 inch of pools bottom

[yarin153]

Hey guys. We just got our new pool.
We still had some working on the yard so the pool got all muddy.
The pool filters emptied most of the water but we still had about & inch of water that we couldn't suck out.
We tried borrowing a water pump from someone but she didn't had enough power to pull the waters out.

We worked for a few hours with buckets to clean it all up.
Im looking for a better solution for next time. Something powerful with a hose that I can put inside and clean all the water untill nothing is left.

I use an industrial pump like they use on building sites to empty rainfilled ditches. I still have to bucket the last inch out
