The build quality is one of its advantages. Quiet. The multicyclone achieves a very high level of filtration by using multiple layers. Serviceability. The pump operates at a high efficiency, while having a very modest motor power. To put it another way, it is quite strong, but it generates heat and uses electricity at a rate that is just half that of its competitors. With these drawbacks: It is said that after a few months of extended, inadequate use, the plastic at the junction of the wheel and the body becomes warped. This is according to a rumor. The opening in the wheel is where the hot air comes out directly. I believe that it is absolutely doable, but I did not run into any difficulties in doing so.
