1. suction
The operating time is indeed in my opinion more than adequate, but by the suction power I would have expected better. I would rather have accepted a higher suction power at the expense of battery life, because if you, anyway again have to get the "big" vacuum cleaner from the chamber for everything lands on a deep-pile carpeting, the device is often not practical use.
2. evacuation
So far I have not gotten to the trick of how to drain the appliance reasonably dust-free without the people and the environment suffer. Also the closure of the red plastic body on gray support part is not so easy to accomplish, since it is a holding tooth must engage in a cut-out and because you have to make a schedule and with sufficient vigor.
3. Charging
The charger is (with or put hand vacuum cleaner) to look nice and has practically a Screw fixing to the wall. However, it seems endless to load and do not switch off if the maximum capacity is reached, because the pilot lamp is on permanently days, but what created me discomfort. Therefore, the hand vacuum cleaner is not normally on but next to the station ... and just then but sometimes not fully charged, what you realize too late.
Overall, I can only distribute 3 stars for this device, therefore, a clear conscience.
