I have a couple jobs that I need to bust up the concrete floor in order to move the drains. Just wondering what your process is and what kind of power tools work best.
Thanks

Best way to bust up concrete floor

Agree ^^^
Rent a large saw, rent a large jack hammer and a few neighbor boys for the labor; this job is brainless and time consuming. If you're cutting heat tubing (as I did on my last job like this) also rent a smaller hammer to chip around the tubes to couple them after.

If you are doing this indoors try to open a window and have someone with a garden hose helping you............The dust and fumes from a concrete saw indoors can be brutal.

I would avoid dry cutting inside, the dust generated is going to be a major mess. Either wet cut or no cut--just bust it up (with a sledge or electric hammer) and patch.

20 LB sledge and a big laborer.
If you only need a small area demo'd, use an sds drill and drill holes about 6 inches apart around the perimiter. Then use the jackhammer to bust out inside the holes. We have done this many times for installing footer pads on remodels. I agree with the saw/dust. It can get unbearable!

Few of these spaced correctly should do the job.

Concrete saw and then i use the Hilti TE 1500 with the drs dust collar with vacuum. Cleans up dust pretty well.

I learned a nifty trick from my old plumber buddy. If he was excavating a trench for a drain he would start with his jackhammer and make a hole about a foot square, then remove the sand/dirt under where he is going and use a sledge to bust out the concrete. Once you have the dirt gone from where you want to go, the concrete busts up pretty easy.

Sawcut with water. Then cross cut into squares. Then drive a tap-con in the first block. Use a claw hammer on the tap-con to pull the first square of slab up.

Here's an interesting product: http://www.archerusa.com/
It apparently expands and causes a pressure of around 20000 psi that will cause concrete to buckle. I don't know how well it would work for you, but drilling the holes you'd need with a hammer drill will produce vastly less dust and noise than a saw or jackhammer.
