Product Description
Karcher KM 85/50 R Bp Rider Floor Sweeper with AGM Batteries
The Karcher KM 85/50 R Bp is a compact battery powered rider floor sweeper designed for high maneuverability in congested areas and narrow cleaning paths. This configuration includes AGM batteries and gives facilities a zero-emission sweeping solution ideal for schools, hospitals, municipal buildings, transportation facilities, warehouses, and other commercial environments that need a compact rider sweeper.
This rider sweeper (ride-on sweeper) is built for easy operation, strong sweeping performance, and simple maintenance. Its compact footprint helps operators clean through door openings as narrow as 36 inches and turn in aisles as narrow as 78 inches, making it a strong fit for confined indoor areas, corridors, and tight layouts where a larger rider sweeper may be harder to maneuver.
The machine uses a polyester flat pleated filter system, dual scraper cleaning, and a practical dual-container debris design to simplify dumping and reduce residue buildup. With up to 41.3 inches of sweeping width and practical productivity up to 40,685 square feet per hour, the KM 85/50 R Bp delivers efficient sweeping in a compact and agile package.

- Excellent for schools, hospitals, warehouses, and public buildings
- Lower maintenance compared with combustion engine sweepers
Best For
- Schools, universities, and large campus environments
- Hospitals and healthcare facilities requiring quiet battery equipment
- Municipal and government facilities with narrow corridors or tighter layouts
- Warehouses and distribution centers with moderate dust and debris
- Facilities that need a compact rider sweeper to clean efficiently in tighter spaces
- Buildings that want rider sweeper productivity without moving to a much larger machine
Not Ideal For
- Very large open facilities that would benefit from a wider industrial rider sweeper
- Facilities requiring wet scrubbing rather than dry sweeping
- Applications with extremely heavy debris loads that require a larger hopper
