I have used the diamond grinder head on a floor buffer rented from Depot before to grind the thin set from a whole house tiled with marble tile.....
Now remember those cartoons where they would spin in circles on floor buffers. That is not a joke and it will happen. It may have only a 1hp motor but it is super torquey. If the cutter grabs the thinset a little and you aren't ready it will rip the handle from your hands and fling it around until it hits a wall or impales the handle back into you.
Since you are just grinding the surface and its just paint you shouldn't have any real issues but it takes practice and lots of respect. It is one of the most dangerous tools I have ever used. I'd rather freehand cuts on the table saw blindfolded then to use one for removing thinset again.
If you do go that routs make sure the cutter has actual diamond material left on it. They wear away pretty quickly and depot is known to send them out with almost no abrasive left.

I already tried that not much came off even when I use the sand injection unit that I have takes a long time.

Well I rented the grinder from Home Peepot and ground most off it off still need up against the walls boy did I have a lot of concrete and paint dust I would say at least 30 gallons. I did it in 4 sections about 1.5 hours each. The worst part was sweeping it out
