As for a vacuum cleaner with dry cleaning, there are no complaints. I myself have an ordinary Saemi vacuum cleaner in use, I have been using it for more than 3 years. When wet cleaning is added, the cleaning area is reduced by a factor. Not always cleans even 40m2 (depends on cleaning modes). Control via the application is convenient, but there is no hall cleaning. Since there is no upper sensor, it draws a map through "cutting" into objects. From wet cleaning, you should not expect anything more. It's just wetting the floor with water. But pellets of dust after such cleaning do not remain as from an ordinary rag. Doesn't remove dry stains. You also need to choose the surface where the base will stand. On tiles without restrictions, but if on a laminate or painted floor, you must always remove the water tank, otherwise the floor will swell.
