A trolley wringer system of this type is a cleaning tool used in commercial, industrial, or institutional settings (e.g., schools, hospitals, hotels, large offices) to mop floors more efficiently. It combines two wash‐buckets, a wringing mechanism (specifically a down‑press type), and a metal frame on wheels (castors) so it can be moved easily. The “36L” refers to the capacity (liters) of water the buckets can hold (often total or per clean/dirty division). The 2 buckets allow separation of clean/cleaning solution water vs. dirty/rinse water. The metal frame provides durability, stability, and better handling under heavy usage. Two separate buckets: one for clean/soapy water or cleaning solution, the other for dirty/rinse water. Each bucket will likely be made from durable plastic (e.g. polypropylene or similar) capable of resisting cracking, chemical corrosion, and frequent filling and emptying. Capacity is around 36 liters (could be split between the two buckets, or one bucket full, one smaller).
