Assembling the turbo brush and the vacuum cleaner

Assemble the turbobrush and the vacuum cleaner according to instruction manual.

Using the turbobrush

To avoid obstruction of rotating element remove big rubbish from the cleaned surface before cleaning.

  • Switch the vacuum cleaner on.
  • Set the regulator on the turbobrush body depending on the height of carpet hair.
    • Short hair carpet – move the regulator towards the sign .
    • Long hair carpet – move the regulator towards the sigh
    • In order to use the vacuum cleaner with the, turbobrush safely, especially while cleaning  long hair carpets and animal skins, it is recommended to test the suction power of the turbobrush on a small area of the cleaned surface.
  • Slowly push the turbobrush back and forth.

Do not hold the working turbobrush for a longer time in one place, but constantly move it, so as not to damage the carpet (fitted carpet). While cleaning carpet fringes always move the turbobrush the direction indicated by the arrow (Fig.k ). It prevents getting the fringes into the rotating brush. The speed of the brush roller rotation depends on the amount of dust in the dust bag and cleanliness of filters. The roller may stop rotating on the carpet. Then the dust bag and filters should be replaced.

Maintenance and cleaning

Maintenance and cleaning of the turbobrush

Before cleaning and maintenance of the turbobrush it must be disassembled from thevacuum cleaner.

Cleaning of the rotating brush
