The vacuum cleaner has very good suction power and comes with a wide range of accessories, so it does a good job when it comes to cleaning itself. Unfortunately, its performance is significantly hampered by poor battery life, particularly when using Turbo mode and the mopping function, which are practically essential in everyday use. As a result, its practical use is limited, and the need to buy an additional, expensive battery if required also detracts from the overall experience.
Excellent suction power in Turbo mode. It extracted a large amount of dust from the carpet, even after it had already been vacuumed with a standard vacuum cleaner.
A wide range of accessories for various types of cleaning.
Overall, the workmanship is decent and the build quality feels solid.
Bosch is recognised as a trusted, high-quality brand.
Very poor battery life, especially in Turbo mode. On a single charge, it often doesn’t even manage to vacuum a single room measuring around 25 m² with a small carpeted area and the rest covered in laminate flooring.
It runs out of power quickly even when mopping, as you need to use Turbo mode to ensure the mop heads spin properly.
When mopping, it often can’t even manage a single room on a single charge.
Buying a second battery for around 2,500 Kč doesn’t make much sense to me for a vacuum cleaner that’s already quite expensive to buy.
Some attachments do not click into place securely, but are simply fitted onto the nozzle by applying pressure. So, when I was vacuuming a mattress or a sofa, the attachment would keep falling off.
Long charging time (approx. 4 hours)

Great satisfaction. It has excellent suction, isn't as noisy as the competition, and is easy to handle. A mop that also vacuums is another big plus. Excellent additional attachments. And the biggest hit is the armrest – it’s absolutely brilliant. The light is also very practical. The battery life is fine – when you're using the turbo, it runs out faster – obviously. In any case, we’ll buy another one with a slightly larger capacity.
We couldn't find any.

After 2 weeks using, I can say that this is ideal for a small apartment up to 40m2 in my opinion.
Battery life is the limiting factor for anything bigger as you need quite a bit of time to fully recharge it, one solution is to buy additional battery to swap it out and that adds to the price as they are not cheap. For vacuming with all the accesorries its absolutely great, for moping it does its job but drains the battery ther most, on ECO it can work for up to 30-40min in my expirience.
Moping is also great on this as it is also simultaniously vacuming! All in all, i would give this a solid 9/10
The missing point for perfection is the battery, if 2 were included or the one lasted for an hour.

It's quiet
Flexible attachment gets into small spaces
It's flexible, so it gets under the bed
Replacing the Bosch POWER FOR ALL battery
Adjusts performance to the surface
Low battery life for a larger apartment, especially if you have carpets, but the battery can also be used from a Bosch drill, for example
Only 2 accessories can be attached to the wall mount

The vacuum cleaner is aesthetically and qualitatively made and has nice extra features such as a magnetic holder, a flexible joint or a well thought out filter cleaning. All parts can be easily removed and removed. Nothing jams or stalls. Overall, it is easy to handle. It can mop and vacuum surprisingly efficiently and saves a lot of time. But the biggest problem is the battery, which really can not tighten the larger apartment, and it is necessary to buy a more powerful one.
Vacuums and mops very well at the same time
It is simple to understand and then use
A flexible joint to get under the furniture is helpful
It shows the quality of workmanship
For a weaker person or child it may be a little harder
The basic battery does not last long, for a larger apartment the need to buy a stronger one
The vacuum cleaner is more robust so you can't get into some of the smaller corners
