Almost 5 stars for such a low price it has, but due to some disadvantages, it will receive this rating.

Just finished cleaning a parquet floor with a lot of hair and fluff.
When I opened the bin, I didn't expect to see such a result at all.

Advantages:

Lightweight
The handle has a switch that allows the vacuum cleaner to easily go under the bed (I really loved this, right?)
The battery (after a full overnight charge) lasted 15 minutes without losing speed
Cleaning the bathroom faucet was easy.
Quite efficient considering the money you spend...

Disadvantages:

Noise (definitely not for nighttime, also not suitable for large houses)
On pebbles, it takes several passes to pick them up.
The construction needs attention to avoid breaking. If you are a person who hits the vacuum cleaner against walls and beds, it's probably not for you...
It cannot clean 90° corners, so you have to use a handheld brush, for example, with a thin bristle to do a proper job.

My conclusion...

It definitely worth the money, for a small house with tiles.

P.S. Do not let rechargeable batteries of any kind (mobile phones, other types of AA, etc.) completely discharge.
After using the device, recharge them again until about 80% (if you can see that) and they will last you for about 3-4 years...

I have it for 3 years. Light, practical, fast, easy to store and goes everywhere. Perfect for quick cleaning without getting tangled up with cords and heavy vacuums.
Cons:
1. Battery life lasts about half an hour (I charge it once a week)
2. It becomes slower on thick carpets and drains faster.
3. The handle gives you the impression that it will break when you vacuum because it is very light and flexible, which has not happened so far.
One thing is for sure, though, if it breaks down, I will buy it again.
