DAVID® PRO-DX PRODUCT FEATURES
4
Designed for All Floor Surfaces.
Automatic Height Adjustment for All
Floors – Based upon the resistance of the
brush roller against the floor, the power
head automatically adjusts up or down to
the appropriate cleaning height, providing
optimal cleaning of all floor surfaces.
The
height adjustment chosen by the machine
ensures aggressive brush action, while pro-
viding optimal air flow. This prevents suffo-
cation of air flow due to improper height
selection.
Never again manually adjust the
brush height or use different vacuums for various floor sur-
faces; the DAVID
® PRO-DX cleans them all, automatically!
Brush Adjustment Indicator Lights –
Two lights, one for “up” and one for
“down,” illuminate to indicate when the
brush roller is in the process of adjust-
ing to the proper cleaning height.
Optimum cleaning occurs when both
lights are off.
Bag Full or Clog Light & Auto Shut Off –
A warning light will illuminate and the
machine will automatically shut off,
when it senses a full bag, a clog in the
airflow pathway, or an excessively dirty
micro filter.
If the user ignores this warn-
ing for approximately 30 seconds, the machine will shut off and
the “BAG FULL OR CLOG” light will flash. The user should turn the
switch off, unplug the machine and immediately insert a new bag
or remove the clog (to remove a clog, refer to the Clog Removal
section on page 10). If the user restarts the machine without hav-
ing solved the problem, the “BAG FULL OR CLOG” light will again
illuminate and the machine will shut off in 30 seconds.
This fea-
ture prevents damage to the motor due to overheating.
Brush Deterioration Light – To ensure optimum cleaning at all
times, a warning light will illuminate to indicate when the brush
roller should be replaced due to excessive wear.
The red
“CHECK BRUSH” light will illuminate (after a 10 second delay) to
notify the user that the brush roller is too worn and, therefore,
should be replaced. The light will remain illuminated until the worn
brush roller is replaced, but the machine will continue to operate.
Brush Obstruction Light & Auto Shut Off – A warning light will
quickly flash, the brush roller will immediately stop spinning
and the vacuum will shut off, if an obstruction becomes
jammed in the brush roller. This prevents the belt from break-
ing and protects the motor from damage.
The user should turn
the switch off, unplug the machine and immediately remove the
obstruction. If the user restarts the machine without removing the
obstruction, the machine will again shut off in 3 seconds and the
“CHECK BRUSH” light will flash.
Stationary Use Light – A warning light will slowly flash when
the machine is standing in its upright locked position (which
causes the power head to rise to its highest point from the
floor) yet the brush remains in contact with the carpet fibers.
This feature warns of potential carpet damage caused by
excessive time in a stationary position, during which carpet
fibers remain engaged with the brush, usually on medium to
high pile carpet.
Two Modes of Automatic Height
Adjustment – The DAVID
® PRO-DX
offers the user a choice between two
modes of automatic brush agitation.
The default setting is perfect for most
flooring types, but more aggressive
and deeper brush action can be activated by pressing the
Brush Mode Button, located on the power head. This enables
the spinning brush to attain greater resistance against the
floor surface before height adjustments are made. For users
who like automatic height adjustment, but still want a choice,
the DAVID
® PRO-DX is the solution!
Flat-to-the-floor, 5.5-inch Profile – Such a low profile makes
cleaning under furniture and beds easy!
Instant-use Wand and Suction Hose – The integrated instant-
use cleaning wand or suction hose is always ready. Just pull
out either tool, or both together, to clean hard-to-reach cor-
ners, edges and crevices. The suction hose is ideal for clean-
ing furniture. And an optional nine-foot extension hose is
available, which creates a total hose length of 15-feet, perfect
for cleaning stairs. Choose from a range of optional attach-
ments that can be fitted to the cleaning wand or hose. The
wand and hose together have an eight-foot reach for instant
cleaning of hard-to-reach areas.
Forty-foot Cord – A 40-foot cord saves time because it mini-
mizes the number of electrical outlets needed during use.
Three On-board, Full-size Tools and Large Filter Bag – The
vacuum comes standard with a crevice nozzle, dusting brush
and upholstery nozzle. Many optional accessories are also
available. The filter bag has a dirt capacity of 1.4 gallons.
Best Pet Vacuum – Because of superior power-head and
brush-roller technology, the DAVID
® PRO-DX vacuum is
excellent for pet hair removal!
Rubber Wheels and Soft Bumpers Protect Homes – Smooth-
gliding, rubber wheels protect hard floors and provide excep-
tional maneuverability. In addition, the bumpers that sur-
round the power head protect furniture, walls, and vacuum
housings from incurring scuffs and scratches during use.
