We have been using the device for about 2 months now. According to the manufacturer, the charging time is a total of 3.5 hours. In normal operation, it runs for about 20 minutes - a little less with the turbo function. Our experience shows that these values are very good. After use, we always hang the vacuum directly in the holder where it is also recharged. We have had good experiences with it. I can really recommend the device.
