Opening The Air Inlet Valve - Miele S 4000 Series Operating Instructions Manual

Use

Opening the air inlet valve

(not on models with radio-controls on
the handle)
It is easy to reduce the suction power
for a short time, e.g. to prevent rugs or
other objects being sucked into the
vacuum cleaner.
^ Open the air inlet valve far enough to
reduce the suction power.
The floorhead will be easier to
manoeuvre. Close the valve up again
when you are ready to use full power
again.
