The BD 50/50 C is Kärcher's 50-litre walk-behind scrubber dryer, propelled by the rotation of its brush. It uses a single 510 mm disc brush with an 850 mm V-shaped squeegee and is sold in several battery packages, including a lithium-ion version.

Variants and what to check

All BD 50/50 C battery packages use the same 510 mm disc and 479 mm pad drive board. Because the machine moves by brush rotation, a worn or flattened brush also reduces drive; replace brushes in good time. The 510 mm disc is the same size Kärcher lists for the BD 50/70 R and the D51 head of the B 40/B 50.

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 50/50 C) and, if you have it, the OEM part number from the old brush.
