What is a dish pool floor?

I was looking at the Aquabot pool cleaners since most of the reviews I have seen about the robo kleen are not very favorable.

the Aquabot jr is for a flat pool floor, and the rover and the thunderjet are both for dish pool floor.

What is a dish pool floor?

Some above ground pool owners scoop out the bottom so it is like a bowl to add depth to the pool. It makes the center of the pool a foot or two deeper than the sides. This is a dish bottom.
