aintenance and care
Select models only
The TurboBrush should be checked regularly for
clogs or debris wrapping around the brush.
1. Unplug the vacuum from electrical outlet.
2. If a clog is present or debris is visible, unscrew
the two screws on the back of the TurboBrush to
remove the faceplate and clear any obstructions.
3. To clean debris from the brush, remove the
brush from the drive belt and clean debris.
4. Reposition the drive belt on the brush. Place ends
of brush in slots on sides as shown. Reposition
faceplate and secure with two screws.
Clearing clogs
Low suction or poor pickup may be due to a clog
in the vacuum cleaner. If you notice a change in
the sound of the motor, check for clogs.
1. Unplug the vacuum from electrical outlet.
2. Empty dirt container.
3. Check upper tank for build up or clogs.
4. If you notice a clog in the upper tank,
remove the separator plate (see section
"Cleaning the Upper Tank" on page 16).
5. Grasp the curved wand and separate it from
the hose wand base. Check for a clog in the
base, the wand or in the hose.
NOTE: On select units that have the clean
filter indicator, when the indicator reads
black, there is a clog in the hose which is
diminishing suction power. Remove the clog
in the hose to restore full suction power.
6. Remove the Twist ‘n Snap hose from the vacuum
by turning to the right. Straighten the hose and
unclog with a long, narrow object.
7. If you notice debris or dirt clogged in the connect-
ing tube, remove it by pulling it out at the top and
lifting the tube out. Clean the tube of any debris
and clear any possible clog from the port to the
pre-motor filter. Reattach tube by first installing
the base and than push in the top of the tube.
8. If the clog persists, follow the instructions for
checking the rotating floor brush and drive
belt on page 12 and inspect the air
passageway for obstructions.
