If you want a newer model than the cheapest now 606th and 616th, but take the top models that build a map of the premises, "strangles the toad" - take this model. The golden mean, as they say. He works with us every day, starts at 12.00, cleans up for about 1.5 hours and goes to the base. For all the time, the base was not found only once (but this happens in expensive models too). With a chaotic ride, in general, it cleans up pretty well, it’s even convenient that it can drive repeatedly once. For more thorough cleaning, it can be closed room by room. But with daily cleaning and driving around the apartment is also fine. Cleaning this robot vacuum cleaner is quick and convenient. In terms of getting stuck and other things, everything is about the same as with other vacuum cleaners. If there are a lot of objects, cables and other things that are lying on the floor, then, of course, the robot will try to climb on them and may get stuck. I think the fact that for effective cleaning the maximum floor area must be freed up in ANY CASE (even with manual cleaning) is quite obvious. And it would be better to remove all kinds of slippers, wires, etc. from the path of the robot vacuum cleaner, and then no one will get stuck there. In the absence of people, I rarely launch - but we have animals whose traces of surprises (a cat will vomit, for example) a robot vacuum cleaner can spread throughout the apartment. So that's worth keeping an eye on as well. In general, I am satisfied with it, and nothing is perfect in this world. I will wait for models with the ability to build a map of premises to become even more wiser and at the same time cheaper, but for now, the previous ones cope with cleaning completely. For washing the floor - a separate polisher (we have Braava 390).
