With its positives being: The form factor, as well as the small weight. Simple to use and to disassemble. Carpets with a low pile can be cleaned. Doesn't produce much noise. Got cons: The primary brush without any "turbo" or any supplementary embellishments. It is not usually sufficient to provide 5 meters of wire (this is relevant if there is a long corridor without sockets). When used for an extended period of time, it can become rather warm.
