If the ladybug is working, then it vacuums the pool. If it's too big for the bug and the hose, you need to fish it out first--with a skimmer or a "leaf rake"--a kind of skimmer with a very deep bag and a squeegee on the lip.

Do you need a vacuum head? Nobody knows that but you. If you feel like being a bit indulgent, a PoolBuster is a great alternative--no hose, no cord, just stick it on the handle, put it under water, turn it on and vacuum.
