ICE rates the iS1100L+ at 66,740 sq ft/hr. That number is theoretical coverage: cleaning path multiplied by top speed, in a straight line, with nothing in the way.
Nobody sweeps in a straight line. Turns, rack ends, dock doors, the pallet somebody left in the aisle and hopper dumps all take time out of the hour. The rule of thumb is to subtract 30% to 50% for real conditions, which puts the iS1100L+ somewhere around 33,000 to 47,000 sq ft/hr in a working building.
Run the math on your own floor before you spend the money. If you have a 200,000 sq ft distribution center, the low end of that range is a little over 6 hours of sweeping, so one operator covers it across two nights or in one long shift. A 60,000 sq ft plant is closer to 90 minutes, which fits inside a single shift with time left for the rest of the route.
Our floor sweeper sizing guide runs the same math for every sweeper we carry, side by side, so you can see where a walk-behind is enough.
