At 40 pounds, the C430BN follows your hands more than your body. Tight doorways, restroom stalls, the space between shelving units. It pivots without lifting or repositioning. The cylindrical brush picks up loose debris while it scrubs, so you are doing two jobs in one pass.
Push it and it moves with you. The M380B has enough weight to let the brush do the work, so you are steering more than forcing. It tracks straight down long corridors, transitions between surfaces without hesitation, and parks in a utility closet when done.
The M510S is where the machine starts working for you. The brush-assist drive pulls it forward, so you are guiding more than pushing. On a long warehouse floor, one tank-load covers serious distance. Wide enough to make real progress, manageable enough to get around obstacles.
Set your speed, start the drive, and the M510 moves itself down the aisle. The Curtis controller keeps brush pressure consistent from the first row to the last. At 65 decibels, it runs quietly enough for schools, medical buildings, and food facilities during business hours.
The cylindrical brush rotates at 180 rpm, picking up fine dust and grit while the machine scrubs. You skip the pre-sweep entirely. At 18 inches wide with a 31-inch squeegee behind it, you combine two steps into one pass and finish the floor faster.
You climb in, sit above the floor, and drive. The XS90 covers 36,000 square feet an hour, roughly a full warehouse in two passes. At nearly a ton, it holds its line on concrete without correction. Built for industrial-scale operations, not occasional use.
The RD560N sits you low, close to the floor, and steers with a tiller. It turns predictably, holds a straight line on long runs, and gives you 25 gallons of solution before needing a refill. The first ride-on that feels like a real tool in a real facility.
Two brushes rotating beneath you, 26 inches of cleaning width, 617 pounds of machine. The RD660 holds its line even on slightly uneven concrete and runs 4 to 5 hours between charges. At 4,200 square meters per hour, you can run full shifts without stopping mid-floor.
