Sweeping Productivity & Battery Options
The Karcher KM 85/50 R Bp uses the same 33.5" 1 side broom sweeping setup in both machine options. The main choice is whether your facility prefers the lower-cost wet battery package or the maintenance-reduced AGM battery package.
Both machine options include the same standard 1 side broom sweeping setup.
Productivity does not change between the wet battery and AGM battery package.
Which battery package should you choose?
- Lowest starting package
- Variant SKU: MJK98414530
- Good fit when your team can maintain wet batteries properly
- Requires routine battery watering and battery maintenance
- Maintenance-reduced battery option
- Variant SKU: MJK98414540
- Good fit when sealed AGM batteries are preferred
- Higher-cost package than the wet battery version
Choose the wet battery package for the lowest upfront cost. Choose the AGM battery package when reduced battery maintenance is more important than the lowest starting price.
