3.1 Method of Operation
General
The E33XL is a vacuum scrubbing ma-
chine for wet cleaning of hard-surfaced
floors.
3.1.1 Brush Head
Lower brush head (Fig. 3/1) via pedal
before scrubbing. The brushes rotate
and solution supply switches on auto-
matically. When the machines stopped,
brushes and solution supply switch off
automatically.
3.1.2 Solution Tank
Fill the solution tank (Fig. 3/2) after re-
moving the cover. The solution tank
holds 29.8 gallons and the filling level

Operation
3.1.3 Squeegee
The movable squeegee (Fig. 3/3) con-
sists of the squeegee lift-out, the suc-
tion turbine and sealing strips. The
soiled water is wiped from the floor by
means of sealing strips. Squeegee is lo-
wered via hand lever. Simultaneously,
the suction turbine switches on. The
suction turbine works independent of di-
rection of travel and even if the machine
stops. Second actuation of the hand le-
ver lifts the squeegee up again and suc-
tion turbine is automatically switched off
with a delay of 15 seconds.
3.1.4 Recovery Tank
The soiled water is taken from squee-
gee to the recovery tank (Fig. 3/4) by
suction turbine and suction hose.
3.1.5 Travel Drive
The machine features a continuous tra-
vel drive (Fig. 3/6). The electronic travel
drive control realises modification of tra-
vel speed, direction as well as dynamic
braking.
3.1.6 Batteries and Charger
The machine is equipped with 235 Ah
batteries (Fig. 3/5), an automatic char-
ger unit (Fig. 3/7) and a low discharge
signal sender (LDS) for protection
against low discharge.
3.1.7 Options
• Extraction hose including suction
pipe, joint nozzle and wet suction
nozzle
• Mop holder and tool-box for cleaning
utensils
Accessories such as brushes,
rollers, pads, pad holder with
