When deciding between an upright vacuum cleaner and a robot vacuum cleaner, I bought it as a gift. Both people viewed Xiaomi's production. It's even nothing as a gift, but if you want to be really satisfied, I suggest looking at more expensive models with self-cleaning and programming options. I normally avoid talking about wet cleaning because it is only used in this device to look impressive (drag of a moist rag). If it's the same for everyone, then it's just laughter, however I don't know how it is with others.
