Before that, there was no cordless vacuum cleaner, so there is nothing to compare with.
Before buying, I chose between v10, XR and v11, as probably many buyers. In fact, the same form, only the motor a little better, well, the battery holds a little more. Whether it's worth the overpayment is up to everyone to decide for themselves, I think both models are worthy and v11 is a smooth evolution. At the time of purchase, v11 cost 4500 more, in principle, why not.
Quite light, although the wife said that it is a little heavy, it is comfortable to hold.
The on can be "fixed" programmatically, which for many will probably be a plus. Although I haven’t used it yet, I’ll probably start, because it’s a bit of a pity to waste the engine’s resource on frequent switching on, there will be a little more consumption, but that’s enough for me.
About the consumption of the battery, again, I just have enough to walk around the apartment with a margin a couple of times and only then I put it on charge.
Cleaning is fast, you can up dust from hard-to-reach places.
Emotions are pleasant from the device.
