update after 2 years. The battery remains the same, meeting expectations in terms of duration. It has not presented any issues in its functionality.

I have read reviews prior to purchasing this product and it is definitely worth the money. The battery lasts for 23 minutes on high power and 40 minutes on medium power. It effectively cleans dust, hair, and other debris. It is sufficient for cleaning the entire house in 23 minutes because you can clean without any interruptions since it doesn't have a cord to deal with. I have two dogs and a cat that shed hair and scatter litter, so it is very convenient that it can be easily maneuvered and fit under tables. It is easy to empty, and it is currently very powerful. The charging base is also very convenient, and it can even stand on its own if it touches a wall. Mine is made in Germany. It has a rotating brush on the bottom, which should be closed (it has a button) when cleaning carpets with tassels; otherwise, it may collect the tassels. It may not be suitable for high-pile carpets, but it works great on plain carpets. The built-in lights for dark corners are quite handy. With the special attachment, it can effectively pick up hair from sofas, tables, pillows, and other furniture. It also works well for cleaning the car.
