Despite Their Noise
Twin tub extractors do have the benefit of not merely gravity draining, but use of a pump as well. Stand alone domestic extractors with pumps are more expensive than the more common gravity draining units. Creda, Frigidaire and other European spinner brands offered and or offer units with and without pumps.
Being as the above may, lack of a pump can mean longer machine life, as there is really only the motor as the main working part of the spinner.
If one is going to purchase a spinner, know that there are two types of motors. Older and some modern units use motors that start out at full speed, which will throw anything inside the tub right against it, and also can cause unbalance situations. Other units use induction or other types of motors where the spinning is gradually ramped up to speed. This process is gentler and less likely to "throw" the unit out of balance.
Spin-X has a unit designed for swimsuits and such that uses the slow ramp up to speed design.
