The Nilfisk Debris Tray Kit (e.g., part number 9100000795 for ALTO models, or 56390779 for Nilfisk Advance/Clarke scrubber-dryers) is a genuine OEM accessory designed to catch and contain larger debris such as rags, paper, and coarse particles before they enter the recovery tank. Measuring approximately 282 × 210 × 210 mm and constructed from durable plastic, it helps prevent blockages, extends filter life, and simplifies cleaning – making it essential for maintaining suction efficiency during heavy-duty or industrial cleaning tasks.
