Significant development with V8; it can now function as well as a conventional vacuum. This is nothing more than a dust disintegrator in space compared to the wireless Bosch. The home functions like a Kalashnikov, and it has two stories and two canine guardians. brings in 2 containers before the power runs out. V10 is completely content, and I have no idea how much better V11 is. The earlier V8 model is far less effective when dealing with family; it cannot even pick up dropped food.
