I bought a robot in exchange for the simplest vacuum cleaner, this one is of better quality, in terms of functionality and in terms of cleaning. Plus, in a shorter time, cleaning is more thorough. It requires less follow-up, everything can be found from the application on the phone. Pros: Top robot vacuum cleaner. I like that the vacuum cleaner does not blunt when there are a lot of objects. It even drives on large thresholds, according to the passport it is indicated up to 2 cm, I have 1.5 cm and everything is ok. The cleaning quality is top notch. Its cons: If only the price can scare away and only. But he's worth it.
