Industrial Sweeper-Scrubber Productivity
The Karcher B 300 R I Bp is designed for large-scale floor cleaning where separate sweeping and scrubbing steps waste time and labor. By combining debris collection, scrubbing, and water recovery into one machine, the B 300 R I Bp helps facilities clean large areas faster.
Expanded sweep coverage helps improve productivity in large open areas.
Large tanks reduce interruptions on long industrial cleaning routes.
When a sweeper-scrubber makes more sense
- Loose debris, sand, dust, or packaging material regularly collects on floors
- Separate sweeping and scrubbing steps take too much labor time
- Large indoor areas require high cleaning coverage per shift
- Facility needs either zero-emissions battery operation or diesel power
- Industrial cleaning routes require wide working widths and large tanks
Actual productivity may vary based on debris level, soil level, operator speed, side brush configuration, side scrub deck configuration, battery condition, dump time, refill time, and facility layout.
B 300 Battery vs Diesel
The Karcher B 300 R I platform is available in battery, LPG, and diesel configurations depending on the facility and cleaning environment.
- B 300 R I Bp: Battery powered for zero-emissions indoor cleaning in warehouses, airports, manufacturing plants, schools, and government facilities.
- B 300 R I Diesel: Diesel powered for outdoor or heavy industrial environments where maximum engine power is required.
Battery and Diesel Operating Considerations
The B 300 R I Bp uses a 36V / 805Ah industrial battery system for long indoor cleaning shifts. Diesel configurations are designed for facilities that prioritize engine power, rapid refueling, and extended operation.
- Battery Type: 36V / 805Ah industrial battery system
- Charger Included: 36V, 100A, 480V battery charger
- Battery Best For: Large indoor facilities that need zero-emissions cleaning
- Diesel Best For: Industrial and outdoor applications requiring engine power and rapid refueling
- Charging Note: Confirm facility power requirements before purchase because this configuration uses a 480V charger.
