I rented that Bosch unit to crack open my basement floor to install a sump pump. It had awesome power, but everything in the house shook.
Few years later, I rented a small Makita to demolish my concrete patio step.
I went with Makita because I wanted a more controlled and accurate demolition to limit the transfer of any vibrations. You are right in that my demo project probably took about 4 hours longer than had I rented the Bosch unit.
