An automatic floor scrubber does the work of a mop and bucket in one pass. It puts down cleaning solution, scrubs with a spinning brush or pad, and a squeegee and vacuum at the back pull the dirty water into a recovery tank, so the floor is left close to dry. These rankings cover walk-behind machines sold for commercial floors: Clarke, Advance, Viper, Tennant, Minuteman, Kärcher and Powr-Flite, plus import brands such as Sunmax, Karhdir, ARBRIX and Dapper Supply. Ride-on scrubbers, robot floor cleaners, household wet-dry vacuums and spin mops, and buffers with no recovery tank are left out.
Cleaning path is the first choice. It is the width scrubbed in one pass, and it sets both how fast a machine covers a floor and where it fits. A micro scrubber with a 12 to 16 in path gets around restroom stalls, kitchen equipment and tables. A 20 to 22 in machine covers a warehouse or gym in half the passes but needs open floor and wide doors.
Power is the second. A corded machine never runs flat and has no batteries to replace, but it only reaches as far as its cord and needs an outlet nearby. A battery machine goes anywhere. Sealed AGM, gel and lithium batteries need no upkeep; wet lead-acid batteries need regular watering.
Brush type matters on tile. A disc brush or pad is the usual choice for smooth floors like VCT, sealed concrete and epoxy. A cylindrical roller brush spins much faster and reaches into grout lines and textured tile.
