It’s a great time-saver as it vacuums and mops in a single step. It’s the ideal helper for everyday cleaning (it can be used as a small handheld vacuum cleaner). The battery life is just about enough, but I appreciate the fact that you can buy a spare battery. Charging does take a little longer, but this can be sorted out by buying a fast charger. I see it as a minor drawback that the same cloths are used for mopping the whole time, so they need to be rinsed out by hand or replaced during longer cleaning sessions. Overall, however, I rate the product very highly.
Vacuuming and mopping at the same time
Lightweight and easy to handle.
A handy LED light on the nozzle that reveals all the dust on the floor; -)
18V battery compatible with the Bosch Power for ALL system.
Flexible articulated tube (Flex Tube) – ideal for vacuuming under the sofa – no bending required.

The vacuum cleaner picks up dirt well, is easy to use, and the flexible tube makes it easier to clean under furniture. I appreciate the wide range of accessories and the battery, which can also be used in other tools. My only reservation is that the nozzle attachment hasn’t been changed – it broke on the previous model after a while.
good performance
easy operation
flexible tube
LED lighting of the nozzle
a wide range of accessories compatible with the previous generation
a battery that can also be used in other tools
smaller dust container
The nozzle mounting is prone to damage

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.

Powerful suction – picks up dust and small debris in a single pass.
Lightweight and easy to use – it’s easy to manoeuvre, even under furniture.
Long battery life – I can clean the whole flat on a single charge.
Quieter operation compared to standard vacuum cleaners.
