I bought it after a lot of market research.
Everywhere I read about other models that one battery doesn't last and you can't finish cleaning the whole house, so I ended up with this one that has two batteries.
However, I was disappointed because both batteries, fully charged, one lasted to clean a mattress and a sofa, and the other two large rugs, meaning the rest of the house floors, etc. were done another day.
Because I had it open-close, thinking that it consumes more battery, I mean I closed it when I wanted to lift a chair to clean underneath, I closed it in those seconds you need to make space to pass or tidy up, it turned out that this was a mistake, it consumed more battery, so it needs a steady intensity and to be constantly open.
As for its power, it is an excellent tool, it sucks everything, makes your rugs look new, dust, hair, everything inside, after you see the bin afterwards and you say, really? Did I have so much dirt?
Also, there are plenty of accessories for whatever you need!!
So, in the very positive aspects, the excellent cleanliness it provides, and in the negative aspects, the batteries which require study and proper management.
