Speaking of used ones, how about the COLMO cloud picture washing and drying suit? Does it work?

Very good. This suit is used in my home. There are 15 spiral spray nozzles embedded in the 36-degree swirl plate inside the washing machine. When the inner cylinder rotates at high speed, it will form a swirling meteor stream, which will balance the water flow on the cylinder wall and produce a water film to care for the clothes. Moreover, the dryer of COLMO cloud picture uses ultra-low temperature heat pump drying technology, and the average temperature of the inner cylinder is as low as 42℃, which saves energy and protects clothing fibers.
