Bosch Motor Technology – Power made in Germany.

Enjoy powerful constant performance with Bosch vacuum cleaners: Developing and producing our high-performance motors in Germany for over 65 years, we not only expect a vacuum cleaner to deliver optimal results but also to be long-lasting, which we warrant with our 10 years motor guarantee*.

Small size with large dust box for convenient cleaning.

Save time and space. The compact yet powerful vacuum cleaner ensures effortless and ergonomic handling thanks to its compact size and lightweight design. The 2 l dust box provides even more convenience, as you need to empty the box less often. Since the device is space-saving, it is easy to store.

Cleaner air and hygienic handling with two filters.

Double hygiene with two filters, one under the dust box and one at the back of the device to ensure cleaner exhaust air in your home. Best of all, thanks to the clever design, you can clean the dust box completely without having to touch the filter - for even more hygienic maintenance.

Convenient handling is important when vacuuming. With our EasyClean System, you get a much easier cleaning experience. The dustbox is removed at the touch of a button without losing any dust. Thanks to its round-shaped design, the dustbox is more easily cleaned because dirt can’t get trapped in corners.

Higher cleaning efficiency even when the dust box fills up.

High performance even when the dust box fills up? With the Power AirCycle Technology and the Bosch Motor technology it is possible. The precisely calculated cyclone and the optimum guided air circulates three times in the dust container and a powerful centrifugal force separates dust from the air.
