SSM 281 | Version 1.02 9
6 Description
The scrubbing vacuum cleaning machine sprays a solu-
tion of water and detergent in the correct concentration
onto the floor and finally removes the dirt by scrubbing.
Through careful selection of detergent and brushes (or
abrasive discs) from the range of accessories, the ma-
chine can be used on a variety of floor types and dirt.
The scrubbing vacuum cleaning machine has a wet sy-
stem that dries the floor immediately after washing. The
drying effect is generated by the suction motor, which
creates a partial vacuum in the dirty water tank. Suction
cups mounted below the tank are designed to pick up the
dirty water film as the machine moves forward and back-
ward.

By turning the knob (Fig. 15), the driving power that the
machine develops can be adjusted.
Fig. 15: Rotary knob for setting the drive
There are two adjustment options:
- In the green setting range, the drive force is increased
and the machine tends to deviate from a straight line as
a result.
- In the yellow setting range, the drive force is reduced
and the machine moves in a straight line.
Do the following to make the adjustments:
- Switch off the machine at the main switch (12, Fig. 5).
- Remove the dirty water tank located inside the machine
and place it aside. Empty the tank if necessary
- Remove the clean water/cleaning agent tank out of the
machine
- Lift the brush/motor with one hand and turn the rotary
knob to the desired position with the other hand (Fig. 15).

Operating
7.8 Battery charge indication (1, Fig. 3)
The battery charge indication has 3 LEDS (red, yellow
and green) and lights up as follows according to the
charge level:
Battery level 100% --> Red, green and yellow LED lights up
Battery level 30% --> Red and yellow LED lights up
Battery level 10% --> Red LED lights up constantly
Battery level 5% --> Red LED flashes; battery fully discharged
After a few seconds, the brush and suction motor are
switched off when the battery is discharged.
7.9 Care by cleaning
The scrubbing vacuum cleaning machine must always
be kept in a clean condition.
8 Operating
8.1 Description of the function keys
- Pressing the brush control button (3, Fig. 3) automati-
cally also activates the suction and detergent flow func-
tions, which can then be controlled and set via the indi-
vidual buttons on the control panel.
- The suction control key (4, Fig. 3) starts the vacuum
motor (LED lights up). A vacuum is then generated,
which is necessary for drying the floor after scrubbing.
The motor only comes into operation when the brush
control lever (6, Fig. 3) has been released.
- The detergent flow button (2, Fig. 3) enables the flow of
the detergent solution (LED lights up). There are 3 le-
vels of detergent delivery available. The flow is activa-
ted only when the brush is operating.
- If the ECO button (5, Fig. 3) is activated (LED lights up),
the machine operates in the economy mode. In this
operating mode, the power of the brush and suction
motor is automatically reduced and the detergent flow
is preset to feed flow level "1".
8.2 Working with the machine
- Press the main switch to switch ON the machine (1,
Fig. 11).
- Press the brush control button or the ECO button (5,
Fig. 11). The brushes as well as the vacuum function
and flow of the cleaning solution get activated.
- To lower the squeegee to the floor, operate the lever (2,
Fig. 11).
- Press the brush control lever (3, Fig. 11) to begin the
work.
Wear protective gloves
Wear suitable protective gloves for cleaning to protect
against injury.
ATTENTION!
Always clean all accessible parts of the machine
after use; empty the tanks and wipe the machine
parts dry with a cloth.
Maintenance and repairs must always be carried out
by qualified personnel; damaged parts must be
replaced only with original spare parts. Cleaning may
not be carried out by children.
ATTENTION!
Never use a high-pressure cleaner to clean the
machine. Water getting into the machine could
damage the electrical system or the motor of the
machine or cause a short circuit.
Do not use solvents or hydrocarbon-based products.
The casing and rubber parts could be damaged.
Avoid hot water and steam, the resulting heat could
permanently deform or damage the plastic parts.
NOTE!
The soil drying function can be operated not only in
the forward motion, but also in the reverse motion of
the machine. Pull the lever (2, Fig. 4) upwards to per-
form the soil drying function in the reverse direction.

Operating
SSM 281 | Version 1.02 15
Fig. 16: Working with the machine
- Check the thoroughness of the cleaning process during
operation. The flow rate of the cleaning agent can be re-
gulated by tapping the cleaning agent button (4, Fig. 11).
Stubborn soiling
For particularly stubbornly soiled floors, the scrubbing
and drying can be performed in two separate working
stages:
Pre-washing with brush/pad
- Operate lever (2, Fig. 11) to lift the squeegee ledge.
- Press the main switch to switch on the machine (1, Fig.
11).
- Press brush control button (5, Fig. 11)
- Deactivate the vacuum function by pressing the suction
control button (6, Fig. 11)
- Operate brush control lever (3, Fig. 11) to start the wor-
king process
Ensure that it is enough time for the cleaning agent to
take effekt when scrubbing particularly soiled areas. This
helps the detergent to exert its chemical effect to remove
the dirt. The brushes require a certain amount of time to
exert an effective mechanical effect.
rying
- Operate the lever (2, Fig. 11) again to lower the squee-
gee ledge.
- Activate the vacuuming function by pressing the suction
control button (6, Fig. 11) again and move the machine
over the pre-cleaned surface.
The process is similar to a thorough scrubbing process
of the floor. Subsequent routine maintenance work on
the floor is thus less time-consuming.
8.3 Finishing work
- Always switch off the machine via its main switch after
you have finished work.
- Empty the dirty water tank and rinse it out with clean
water
- Empty the water/cleaning agent tank as well.
- Place the machine in parking position.
ATTENTION!
Regularly check whether the detergent solution wets
the brush and make sure that the tank is sufficiently
filled.
ATTENTION!
The battery indication lights up red when the battery
is almost discharged. After a few seconds, the brush
and suction functions switch off automatically.
The battery must be recharged to resume work.

9.7 Adjusting the squeegee ledge
The squeegee is factory-adjusted to achieve an optimum
drying effect on various floor surfaces.
In the event that the drying results do not comply with
your expectations, the squeegee can be re-adjusted:
- The rubber lips of the squeegee blade should be an-
gled 45° from the floor surface along its entire length.
- The height of the squeegee blade can be adjusted by
increasing or decreasing the height of the wheels (1,
Fig. 25)
Fig. 25: Adjusting the squeegee ledge
9.8 Replacing the suction lips
The suction lips pull off the water/cleaning agent film so
that the residual water can then be sucked in.
Due to the regular wiping motion and the contact with the
floor, the rubber lips show signs of abrasion (cracks/
rounded edges). The rubber lips must be replaced as fol-
lows:
- Remove the dirty water tank and the cleaning agent
tank and place them on the floor (see chapter 7.6 "Dirty
water/cleaning agent tank").
