New Advance SC401 B Brush Assist Scrubber
Our Take (from the SES Sales Team)
“The SC401 is for small spaces where a mop and bucket is still the daily routine: convenience stores, gas stations, cafes, classrooms and clinic hallways. It scrubs a 17-inch path and picks up behind itself in the same pass, so floors are dry and ready for traffic right away, and the 8-gallon tanks hold enough for over an hour of cleaning. The controls are about as simple as it gets, with a One-Touch button and a click-on brush, which matters when the machine gets handed to whoever is on shift.
Picking a package comes down to two questions. First, brush assist or traction drive: the 17B is lighter and runs up to three hours, while the 17BD adds a drive motor so the operator isn’t pushing, which helps on longer routes. Second, batteries: the 105 Ah wet set needs regular watering, and the 98 Ah gel set is sealed and maintenance-free.”
A compact 17-inch scrubber for small spaces
The Advance SC401™ is a compact, battery-powered walk-behind automatic floor scrubber with a 17-inch disc brush. Advance positions it as an easy-to-use alternative to labor-intensive mop-and-bucket cleaning in small spaces such as gas stations and schools. Its center-pivot squeegee keeps optimal blade pressure and picks up in forward and reverse, so one pass leaves hard floors clean, dry and ready for use. Choose the 17B brush-assist model or the 17BD with traction drive, each with wet or gel batteries and an onboard charger.
