Has pros: Build quality. Quiet. Multicyclone - a high level of multi-layer filtration. Serviceability. High efficiency of the pump, with a relatively low motor power. In simple words, it powerfully, but it heats up and consumes electricity half as much as its counterparts. Got cons: Rumor has it that with prolonged inept use, the plastic in the junction of the wheel and body is deformed after a few months. Hot air exits directly through the wheel opening. I think that it is quite possible, but I did not encounter a problem.
I thought it would be helpful to share some photos along with my thoughts.
