If not for the hefty cost, every home would have these areas! These are some advantages: Fantastic suction. The battery has enough power for my 90 m2 apartment and still has some left over. Much better than the V7 I was using previously. For an apartment, it was insufficient. The use of a laser beam—which I initially dismissed as pointless marketing—allows you to see where the vacuum cleaner traveled and where there was still dust. Cons are: In my opinion, dust counters are pointless. The laser beam is not effective everywhere; it works well on parquet but is difficult to see on tile. When my friend used my vacuum cleaner, he wanted to purchase it but couldn't find it anyplace anymore:(
