Hand mopping maximum productivity is about 1,000 sq ft per hour. Walk behind scrubbers productivity is about 500 sq ft per inch of scrub width per hour (i.e. 20” machine = 10,000 sq ft per hour). Battery ride on scrubbers productivity is about 750 sq ft per inch of scrub width per hour (i.e. 20” rider machine = 15,000 sq ft per hour). Large battery or engine powered units approach 1,000 sq ft per inch of scrub width per hour (i.e. 40” = 40,000 sq ft per hour).
Traditional disc type scrub brush scrubbers have the lowest maintenance and acquisition costs. They do not possess any sweeping capabilities and do require presweeping to achieve successful operation and results.
Scrubbers with integrated cylindrical type scrub brushes use the scrub brushes to provide wet sweeping as it scrubs to control dust but have limited debris pickup capabilities. They cannot be used as a dry sweeper only. In light debris applications they can most times minimize or eliminate the need for presweeping. Their operational cost will be higher than a disc type but lower than full size combination machines with separate sweep and scrub systems.
Orbital or oscillating type scrubbers use replaceable rectangular pads that can be used to scrub or strip finishes from floors (without chemicals) and are more prevalent in facilities with waxed or finished floors.
As you increase in size the scrubbers are equipped with larger water tanks and battery packs for increased scrubbing time between refills and longer runtimes before recharging, and typically with larger, more powerful scrubbing and vacuum motors for maximum performance and results.
Size of areas to clean
Scrubbing small spaces like break or locker rooms, around production area cells or machinery the smallest 13-17” scrubbers are ideal. Several work in forward and reverse for tight to wall scrubbing and excellent results. Once in open areas they become limited by the water tank capacities and battery run time. These are also great complements to facilities owning larger equipment as a way to clean areas the big machines can’t reach.
Scrubbing facilities under 25,000 sq ft, the 20-26” units are ideal. They have the tank/sweep hopper/battery capacities for higher production rates and run times to match. Typically these units clean more aggressively if needed and are great complements to the larger machines as well.
Sweeping facilities under 25,000 sq ft the 28”-41” walk behinds are most common, though if the aisle areas are open the 46” rider units with the manual empty hoppers work very well.
Scrubbing facilities 15-40,000 sq ft, the 26”-38” walk behind units and the smaller 22”-36” riders are ideal. A little more debris is typical in these applications and the considerations of sweeping needs becomes more prevalent. Machines in this category, using the cylindrical sweeping scrub systems are most common and offer stronger performance, larger capacities and more run time enabling you to clean more areas quicker. For some applications a separate sweeper and scrubber are appropriate.
Sweeping facilities over 25,000 sq ft can be a rider application and over 50,000+ the larger self dumping hopper type sweepers become more common, depending on the amount of debris to be swept in the application.
Facilities over 40,000 sq ft open up the applicability of almost all machines and will vary depending on the desired end result, budget, the time available to spend cleaning (man hours), the total square footage of cleanable area, sweeping needs, facility congestion and aisle widths among other considerations. While many times large combination machines are used, battery rider units in the 34-46” widths and tank capacities in the 35-100 gallon range are the most common.
