Easy squeezy lemon peasey... I have now done several jobs of this type. I like the Hilti rotary hammer with a hooked chisel to pop the tile. Set the drill to hammer mode and get under a corner. Most of the time the entire tile will lift in one piece. The biggest problem used to be getting the thinset mortar off the subfloor so I could set new tile but I could a tool even better at dust extraction than the ras. (please forgive me). Bosch has a 5" grinder with a diamond cup, very effective on masonry, but the entire cup is shrouded, has brissles, and a dust port. Omg, this tool is fast and clean. I recently did two small powder rooms with no outside air supply, a job I would consider suicide by dust inhalation. I took the door handle off to sent the ct hose through and wore my dust mask just in case. No problems.
I bought this tool because I do a lot of kitchen and Bath remodels. Tile demo has always the messiest portion of this job, even with dust wall. Now I have little concern for this tedious job.
