Factory Cat's Floor Sweepers sweepers are built to sweep factories: dirt, dust, metal shavings, foundry sand, bolts, paper, wood, whatever there is. Factory Cat's are compact, not light-duty. The Factory Cat model TR's design was built from the success of our Model 34 walk behind sweeper. The TR's side brooms sweep up dirt in the corners while a huge tubular sweeping broom under the machine sweeps up the dirt and debris from the floor and packs it into the steel hopper. Meanwhile, the second stage vacuums up the dust and traps it in a polypropylene felt "baghouse" filter. Factory Cat's Industrial floor sweepers can pick up whole bags of cement at a time without leaving a trace of dust behind. All Factory Cat scrub decks are protected by steel guards and large polyurethane rollers to keep the unit from marking walls. New to the Mini HD unit is enhanced vacuum motor protection box. This new design makes it almost impossible to flood the vacuum motor with water and debris. This new feature will reduce the cost of ownership on the Mini HD as  vacuum motors are a common item for replacement.
