The rectangular brush is an item that will become indispensable for you. These brushes have plastic bristles that help you scrub the heavily soiled and resistant surfaces such as terrace coverings. However, in the household, you will use these brushes almost only in connection with the respective steam buffers and microfibre cloths.
It is not necessary to keep the steam button pressed constantly when using the brushes; otherwise there will be too much moisture, especially for real wood surfaces and upholstered furniture that should rather be cleaned with impulse steam bursts. When in doubt, please test the suitability for cleaning with dry steam at a hidden place in your piece of furniture.
The brushes can be locked in place at the bottom.
