V8 has come a long way, and today it can take the place of a conventional vacuum. In comparison to the wireless Bosch, this device is merely a dust destroyer in outer space. The house has two stories and two dogs and functions like a Kalashnikov assault rifle. Obtains 2 containers before power is lost. V10 is completely content, and I have no idea how much better V11 is. The previous V8 model is not up to the task of cleaning up after the family.
