When Brush Assist Is the Right Configuration
The BD 20/11L costs less than the LT traction drive model and shares the same 20-inch path, 48.5-lb brush pressure, and tank capacities. Brush assist suits operators who clean shorter zones where fatigue from pushing is not a concern — retail stockrooms, medical office suites, small school corridors — or facilities that prioritize lower acquisition cost over self-propulsion. The 157-lb weight without battery is 30 lbs lighter than the LT model, making the brush-assist unit slightly easier to maneuver into tight areas. For extended-shift applications in large facilities, the LT traction drive reduces fatigue meaningfully.
