A full charge with a smart brush is not enough for a three-ruble note of 60kv. Perhaps the marriage of akb. At 10% it turns off after a minute. There is no additional battery even on Aliexpress, plus it’s not clear how to charge it on the stand, there are contacts, but they are not suitable for this battery. Charging is long, 30 minutes after a full discharge, only 4%. And it vacuums well after a wired philips from the carpet in the bedroom collected another handful of hair and dust. Nozzles are easy to change. Suitable as a second for a quick cleaning during the week. For weekly stays wired.
