I got it for 80 euros on Black Friday.
For that money, it does a decent job in an apartment with a dog. Now, whether it will withstand the test of time remains to be seen.
At its regular price, I would go for another one with mapping.

Unfortunately, it never worked for me! As soon as it finished charging and I gave the command to start, it would take a step and then freeze in both seconds. I would put it back on the base and it would start charging from the beginning, only to repeat the same scenario. I was deceived by a good review that I read and fell for it. In my opinion, stay away from cheap Chinese products. You are tempting fate! Now I am in the process of replacing it and I don't know if I will succeed. If I had known from the beginning, I would have gone for something more expensive!

I have used it twice and I am very satisfied. It cleaned very well in a dirty house with a cat and hair. It does stop on the stairs and, as it claims, it can also climb small heights. I will come back with another review after some time when I have a more complete opinion.

I have bought it for 1.5 years now and I have not regretted it for a moment. I use the Miele vacuum only for general cleaning once a week. I use it daily and seeing the dust it collects every day makes me think that even if I didn't work, I wouldn't be able to use a vacuum every day in any case. The house is always clean now.
I should note that it sucks everything, it does a very good job, even a small pebble from the beach that my little one had picked up, it sucked it up!
