I bought this vacuum cleaner because it seemed to me more functional among analogues. It has a capacious dust collector, a side brush. Using the application to control the vacuum cleaner is easy and simple. In addition, you can create a map of cleaning in the apartment. Battery life lasts for two hours. This time is enough to vacuum the entire apartment. With its pros. High quality products and durability of materials; Additional bag for collecting dust in a set; Got cons: For its cost, it does not fly, but the functionality covers it.
