Good.1. Lightweight and easy to handle.2. Sometimes has excellent suck.3. Easy to drain and clean (except for one. See "Bad").4. It is easy to charge and holds the charge for a long time.Poor.1. Sometimes the suction power is mediocre at best. I have no idea why this is so contradictory.2. Pulling out the part that separates the collected dust and dirt from the motor (which you have to do to clean the vacuum) is a real agony. I know I'm weak, but this is ridiculous! I had to use a knife to break the "seal" between the piece of rubber and the plastic vacuum cleaner. So far I have always received a piece. but mostly with great effort!
