Traction Drive vs. Brush Assist — When the LT Wins

The LT designation means the BD 20/11LT has a dedicated traction drive motor (0.16 HP) that propels the machine forward independently of the brush motor — operators guide rather than push. On long cleaning shifts in healthcare facilities, schools, and large retail stores, this eliminates operator fatigue from pushing 187+ lbs across hard floors. The brush-assist BD 20/11L costs less but requires the operator to push the machine; the traction drive LT pays back in reduced operator fatigue and higher productivity over multi-hour shifts. Both use the same 20-inch path and 31-inch squeegee.
