  • Publication number: 20180369981
    Abstract: Disclosed is a concrete floor trowel machine of multiple blades with added floor polishing jacket or attachment. It saves expense and time associated with the use of a separate trowel and a polisher in consecutive order, often a day apart. Furthermore, disclosed is a blade replacement polisher disk with metallic hook-and-loop attached steel wool polisher puck, which is the loop component of that means of attachment. Means of slurry feed and suction removal to said puck is also disclosed, whereas said puck may rotate free or by planetary. Said pucks may be attached to blades. Safety cage and slurry splash cover supplement the machine. Removable caster legs are added to ease moving the off-use machine. Disclosed as well are robotic polisher-grinder modules in tandem or in train with changeable trowel-polisher modular inserts with electrical motors and power cable and water hose reels to be serviced from a distance, remotely controlled.
