ADVANTAGES:✔️ It makes an intelligent tour, starting with the perimeter and then moving along parallel strips there and back (a bit like when you pass the lawn mowers). Once the first room is completed, he moves on to the next one, the one he finds closest and so on. ✔️ Practical, comfortable and quite simple to use, it has relieved us of a task, because it does its job quite well and manages to get almost everywhere, except obviously narrow places where it doesn't fit. You can't imagine how much dust it raises, which you couldn't even see... ✔️ The first time a general plan is created (which we can customize by dividing further areas if they are not recognized). Then during operation, it passes over each mapped point, without going haphazardly and following the shortest route to clean and return to the base. ✔️ The battery also has a good capacity and allows carry out a complete cycle of an apartment without interruptions. ✔️ The internal dust collection compartment is convenient to extract and empty and is equipped with a filter (this must also be cleaned). ✔️ Laser navigation is much more precise and in fact, compared to the previous model which often bumped into table legs and other furniture, this one recognizes almost everything and rarely misses a piece of furniture. DISADVANTAGES : ❌ Even compared to the version I had before, this one has a terrible voice. Even if she speaks in Italian, she is really robotic and unpleasant (the Xiaomi model purchased years ago instead had a pleasant female voice). ❌ The washing, even if improved because it uses vibration, is still a It helps but it's not a solution. This is aggravated by the fact of not being able to put detergent in the drawer and by having reduced the dispensing nozzles from 3 to 2. As you can see in the video, instead of having a uniform coverage of the floor, there are 2 streaks which however leave a void in the middle. ❌ Very inconvenient to insert the water tank, because it has to be inserted from the side where the charging connectors on the base are located. This means that I have to remove the robot from the base, attach the tank, reposition it on the base and then start it. The previous model also had attachment from the opposite side (much more intelligent and practical).
