Delta Manual

Automatic Power Head Height Adjustment. Based upon the resistance of the brush roller against the floor, the power head automatically adjusts up or down to the appropriate cleaning height. The adjustment process is indicated by two green lights labeled “UP” and “DOWN” located on top of the power head. The height adjustment chosen by the machine ensures proper brush action, while providing optimal air flow. This prevents reduction of air flow due to improper height adjustment.

Stationary Use Warning. When the machine has its handle in the upright-locked position, it is designed to disengage the brush roller from the floor by raising the height of the power head. If the power head reaches its highest brush height but is still engaged in the carpet, the “CHECK BRUSH” light will slowly flash to alert the user. This can occur on extremely high-nap carpet, such as loose-pile, shag, or on carpets with extraordinarily thick padding underneath.

However, it is typically caused by the user pulling forward on the machine while using the attachment hose or active wand. This feature was designed to be an alert to the user to “take care” while the machine is stationary. An operating machine should not stand stationary on the floor for inappropriate periods of time.

As delivered the handle will go from vertical to horizontal in one movement. However an intermediate stop position is possible in order to lift the brush head over rug edges, etc. To open the intermediate stop position, move the orange slider (27). In this mode the machine will go flat from the intermediate position if the foot pedal is pressed a second time.

Blockages in the hose can be cleared by removing the attachment hose (12) from the machine by squeezing the retaining ring (4) and inserting the opposite end of the hose in the connecting tube (23).

Stretch the hose upright and switch on the machine. If necessary, quickly lift your hand on and off the end of the hose. If this procedure does not clear the clog, a straight piece of wood can be inserted into the hose to push out the clog. Take care not to damage the hose when unblocking it.
