This vacuum cleaner, and probably every vacuum cleaner of this kind, has a trick - it doesn't collect dust due to strong suction, but because it has a rotating wheel that turns upside down and rubs the dust, or cat hair, or carpet - and then it sucks up the dust.
Its battery is sufficient to clean a 100 sqm house again and again, and you still have 85% of its power - in automatic mode.
The disadvantages are that it doesn't fit in a cabinet like the others - so you have to make sure to place it on a wall or somewhere to charge it.
The great advantage is that you can take it and go all over the house without being hindered by cables and carrying the vacuum cleaner here and there.
It is very powerful, I have it on the low setting because it gets stuck on the medium setting. On the high setting, it gets hot and the manufacturer does not recommend it. It also has an automatic setting that increases power if it finds a lot of dust!
It has a head for hair, many accessories that are not shown here, and a laser head that shows you where the dust is on the floor, very useful.
It also has a sensor that measures the size of the dust with sound and shows it on a small digital screen it has. I haven't figured out how it helps - it says that if it sees very fine dust, it means you may have allergy issues and need to vacuum more.
Now - every time you vacuum, you have to open it and throw away what it collected in a bag, and then clean it with a cloth - so the positives are that compared to a vacuum cleaner with a bag that you don't throw away until it's full - here the vacuum cleaner is clean every time, so it doesn't smell like the others that have full bags and you don't empty them.
It is relatively heavy, here you carry the whole vacuum cleaner - but not so much to tire you.
It has the convenience that you dip it and vacuum immediately - but if you get carried away and vacuum the whole house, you have to clean it immediately. All the parts that it consists of open and can be cleaned relatively easily.
I don't know what magic the heads have, but they don't hold any dust from what they collect! All the dust is gathered on the head.
The head always fills up with one sweep, and even if the house is clean, it will fill up.
Also, all the parts can be washed with plain water - especially the back filter, which looks like paper and fills up relatively quickly - it collects the fine dust that the first filter cannot catch... and the best part is that it gives you a message to clean it and a whole video on how to clean it. These are very important because you don't see when this filter is full and you don't realize it - you only realize that it gets hot and struggles.
The battery is replaceable - which is a big positive.
The downside is the price, I haven't tried other similar ones to say if it is overpriced or not. I was looking for these things on YouTube and in other reviews.
In reviews and tests on the internet, this is the most powerful one with the smallest mechanism - it is only surpassed by an English vacuum cleaner that is not available here and has a different style - similar technology.
