UNO 211 is a compact stainless steel cleaning trolley with wringer. It has two stainless steel buckets with a capacity of 8.5 liters each at the front and two 8.5 liter stainless steel buckets at the rear. The rear buckets are placed in an easily removable bracket and allow the storage of fresh and used mops. The PurMop® wringer has been developed for use in cleanrooms and is made of polished stainless steel. The innovative function of the wringer enables improved reproducibility by means of a defined wringing pressure and reduced user effort thanks to the force transmission mechanism.
