CHECK WAND
Detach the wand and check it for blockages.
Make sure to clean the Detect sensors
regularly, as hair and other debris may build
up and obstruct them. If the sensors are
partially obstructed, Detect mode will not
function as expected.
CLEANING THE FLOOR DETECT SENSOR
1. Step on the foot pedal to detach the
nozzle from the wand.
2. Turn the nozzle over and locate the Floor
Detect sensor on the bottom.
3. Use a cotton swab to wipe away dirt and
debris from the sensor and surrounding area.
MAINTENANCE
SELF-CLEANING BRUSHROLL MAINTENANCE
CLEANING THE SOFT ROLLER
1. To remove the Soft Roller, slide the Eject Roller Button on the floor nozzle.
2. Tap loose debris off the Soft Roller. Use a dry towel to wipe it clean, and to remove any
debris caught in the teeth behind the Soft Roller.
3. Hand-wash the Soft Roller as needed. Use only water, let it air-dry completely for at least 24 hours.
4 Reinsert the Soft Roller and press it in until it clicks securely into place.
NOTE: For best performance, keep the Soft Roller clean with regular maintenance.
If any hair is wrapped around the brushroll,
continue vacuuming, using Carpet mode
on a hard floor surface, a low-pile carpet,
or a small area rug. This will allow the self-
cleaning brushroll to remove the hair wrap
and send it to the dust cup.
If you run over a hard or sharp object or
notice a noise change while vacuuming,
check for blockages or objects caught in
the brushroll. If some fibers remain wrapped
around the brushroll after continued use,
clear them from the brushroll.
