A recently granted patent (Publication Number: US11918163B2) discloses a unique cleaning system designed to efficiently clean textiles. The system comprises a bucket with a liquid-permeable basket that can be set into rotation and adjusted in height using different actuating devices. The cleaning device, equipped with a handle and cleaning textile, is detachably connected to the basket in a rotationally fixed and stress-resistant manner. The second actuating device, which includes a handle and a ballpoint-pen mechanism, allows for easy adjustment of the basket's position within the bucket, serving both as a wash-out and spin-dry basket for the cleaning textile.

Furthermore, the patent details the functionality of the first actuating device, which involves a lever and transmission to convert vertical movements into rotational motion for the basket. The bucket's design includes a bottom that acts as an abutment for the ballpoint-pen mechanism, limiting the basket's lowest position. Additionally, the coupling mechanism between the basket and cleaning device is described to include locking and/or magnetic features for secure attachment. During operation, the system ensures the cleaning textile and basket remain submerged below the mean water level in the bucket at the lowest position and above it at the highest position, with the bucket's internal height accommodating this range effectively.
