Frequently Asked Questions
What type of machine is the Karcher B 300 RI LPG?
The B 300 RI LPG is a combination sweeper-scrubber. It can sweep debris, scrub floors, and vacuum dirty water in a single pass. This dramatically increases cleaning productivity in large facilities compared to using separate sweepers and floor scrubbers.
What is the difference between the battery, diesel, and LPG versions?
The B 300 RI platform is available in three drive configurations:
- Battery (Bp) - Zero emissions, ideal for indoor facilities such as warehouses, airports, and manufacturing plants. View the battery-powered B 300 RI Bp.
- LPG (Propane) - High power and fast refueling, commonly used in distribution centers and large retail environments. This version includes a right side sweep brush and tall overhead guard.
- Diesel - Designed for outdoor or heavy industrial environments where maximum engine power is required.
What types of facilities typically use this machine?
The B 300 RI is designed for very large facilities including warehouses, airports, manufacturing plants, transportation hubs, and large institutional buildings where sweeping and scrubbing must be completed quickly.
Does this machine require pre-sweeping?
No. Because this machine combines sweeping and scrubbing, it can collect loose debris while washing the floor at the same time, reducing labor and improving productivity.
How large of an area can the B 300 RI clean?
This ride-on sweeper scrubber is designed for very large facilities and can clean well over 100,000 square feet per hour under ideal conditions, making it one of the highest productivity cleaning machines available.
When to Choose a Sweeper-Scrubber
A combination sweeper scrubber like the B 300 RI is ideal when floors accumulate both loose debris and heavy soil. Facilities that frequently track in dirt, sand, or packaging debris benefit the most because sweeping and scrubbing can be completed in a single pass.
- Large warehouses and distribution centers
- Manufacturing plants
- Airports and transportation terminals
- Industrial facilities
- Large municipal or government buildings
Why choose a sweeper-scrubber instead of a cylindrical scrubber?
Combination sweeper-scrubbers like the Karcher B 300 RI are designed for facilities that have both debris and floor soil. These machines sweep debris and scrub floors in a single pass using a large debris hopper and powerful roller brush system.
Cylindrical scrubbers can collect light debris while scrubbing, but they use a small debris tray and are better suited for dust, sand, and small particles in facilities like schools, retail stores, and healthcare buildings.
Sweeper-scrubbers are typically used in warehouses, manufacturing plants, airports, and other large facilities where debris levels are higher and maximum cleaning productivity is required.
Looking for a Different B 300 Configuration?
The Karcher B 300 RI sweeper-scrubber platform is available in multiple configurations depending on the drive system, sweep brush setup, and safety equipment required for the facility. Options include LPG, diesel, and battery powered versions with optional dual sweep brushes and overhead guard protection.
