SUCTION CONTROL
To assist with push/pull force of the
vacuum on surfaces like thick carpet, the
suction control valve can be opened to
help reduce suction. Note that for best
cleaning results, the suction control valve
must be fully closed.
· Slide to "Min" to open the suction control
and decrease suction. Opening control
decreases suction for draperies and
lightweight rugs.
· Slide to "Max" to close the suction control
and increase suction. Closing control
increases suction for upholstery and
carpets.
