The BD 50/70 R Classic is a small ride-on scrubber dryer with a 70-litre solution tank, rated for up to about 2,000 m² per hour. It scrubs with a single 510 mm disc brush, giving ride-on comfort with the brush size of a walk-behind.

Variants and what to check
Despite being a rider, the BD 50/70 R takes the same single 510 mm disc as the walk-behind BD 50/50 C, so spares can be shared across a mixed fleet. Batteries and charger are ordered separately on the Classic Bp version and do not affect brush choice.
What to send us for a quote
- Outer diameter of the brush or pad driver, measured across the bristle tips.
- The drive hub on top: clutch-plate type, number of lugs, or the hole pattern — a clear photo is usually enough.
- Trim length (how far the bristles stick out of the block) and the current fill: polypropylene, nylon or abrasive grit.
- For cylindrical decks: overall length, core diameter and the shape of the drive ends.
- Your machine model (Kärcher BD 50/70 R) and, if you have it, the OEM part number from the old brush.
