Before leaving the factory, the machine you have purchased undergoes a series of tests to ensure
quality, safety and efficiency.
If you follow the instructions in this manual carefully, under normal operating conditions, your ma-
chine will last a long time.
Before using the machine, read this manual carefully in order to prevent accidents and malfunction-
ing.
Use
The “BERTA ADV” electrosponge has been designed to clean floors during the grouting of floor tiles.
The machine cleans away excess grout and epoxy sealant, whilst smoothing the joints between tiles.
The machine is suitable for use on floors tiles with terracotta, ceramics, vitrified stoneware, marble, porphyry,
etc.
Precautions
Never leave the machine unattended or within the reach of children.
Keep the working area clean and well lit. Never expose the machine to rain.
Machine noise emission levels under working conditions are provided in the “TECHNICAL DATA” paragraph.
For more detailed information, also see Italian Law 277/91.
Before plugging the machine into the mains socket, make sure that the power supply voltage is compatible
with rating plate specifications.
If it is not compatible, do not plug in the machine and contact an authorised service centre or your dealer.
Always use an effectively grounded cable to hook up the machine. When in doubt, do not plug the ma-
chine in.

Transport
Wind up loose power cables, without knots or kinks.
Never lift or carry the machine by the power supply cable. Never disconnect the machine by pulling the
power supply cable.
Never transport the machine while it is still plugged in.
Unscrew the knobs illustrated in figure 1 and hold down the handle.
To avoid deforming the sponge roller assembly, make sure it is not in contact with the floor and that the wa-
ter dosing lever is released.
Checking before use
Before using the machine, check for any broken, worn or damaged parts and replace them immediately.
For spare parts and accessories, always follow the instructions provided in this manual.
Use only original spare parts.
For the best performance and utmost safety, always keep the machine clean and lubricated.
Always unwind the power supply cord completely and check it for damage.
Before plugging in the machine, make sure the power switch is “OFF”.
Plug the machine into a 230V 10/16A socket. As a precautionary measure, check the information given on
the MACHINE DATA PLATE.
If an extension cord is used, make certain that the section is at least 1.5 mm2.
Make sure that the sponge roller is neither warped nor damaged.
Fitting
Make sure that the tank has been correctly fitted.
Raise the handle and lock at the requested height and position,
by tightening the knobs (A) illustrated in figure 1.

Preparing the machine
Before using the machine to clean a floor, moisten the sponge.
Fill the tank with about 15 litres of cold and clean water.
Shift the lever (A) to its upright position (figure 2).
Operate the switch and let the sponge roller run for about 30
seconds.
Shift the lever (A) back to its horizontal position (figure 3).
The machine is now ready for use.
Using the machine
Before performing cleaning operations, make sure that
the sealant has sufficiently settled.
If the sealant has hardened on the tile surface, wet the
floor and emulsify the sealant with a brush and felt pad.
NEVER INCREASE PRESSURE ON THE SPONGE
ROLLER BY PUSHING THE HANDLE UPWARDS.
Return to the beginning of the area to clean with the
sponge roller in its raised position.
To do so, hold the machine's handle down.
Lower the sponge roller to the floor and start moving
slowly backwards, preferably in a diagonal manner with
respect to the tile installation direction.
By doing so, you will perfectly clean the tiled surface
from any grouting material.
Once you have reached the end of the area to clean,
raise the sponge roller, turn the machine and return to
the beginning of the area to clean.
Lower the sponge roller so that it overlaps the area previously treated by about 5 cm (figure 4).
When cleaning close to room walls, make sure that the motor guard does not come into contact with the
wall.
If foam forms in the tank during use, add a few drops of an anti-foam product.

Dosing water in the sponge roller
To increase or reduce the moisture content of the sponge roller, proceed as follows:
-shift the lever (A) to its upright position (figure 2 - page 6)
-raise the stopping spring (B - figure 5) and remove it;
-loosen the nut (C- figure 6);
-tighten the fork (D- figure 7) to reduce the amount of water in
the sponge roller; loosen the fork to increase the amount of
water;
-refit the stopping spring (B – figure 5) and tighten the nut (C -
figure 6).
Tools
“AVANA” sponge roller with medium absorption properties for cement based sealants.
“SWEEPEX” sponge roller with high absorption properties for cement based sealants.
“CELLULOSE” sponge roller for epoxy resin based sealants.
CELLULOSE SPONGE ROLLER FOR EPOXY PRODUCTS
Before fitting the roller, to prevent it getting damaged, soak it in cold and clean water for at least 1 minute.

Replacing the sponge roller
BEFORE PERFORMING ANY OPERATION, MAKE SURE THAT THE MACHINE IS UN-
PLUGGED.
REMOVING THE SPONGE ROLLER
Shift the lever (A) to its upright position (figure 2 – page 6).
Move to the side opposite the motor casing.
Raise the handle (E– figure 8) and remove the quick release
device (F– figure 8).
Move to motor casing side. Using a screwdriver, raise the han-
dle (G– figure 9) and remove the quick release device (H– fig-
ure 9).
FITTING A NEW SPONGE ROLLER
Shift the lever (A) to its upright position (figure 2 – page 6).
Place the sponge roller into its seat, keeping the side featuring
the hexagonal notch on the right.
When fitting the roller, make sure the rubber water sealing plugs
are facing upwards.
Move to motor casing side.
Fit the quick release device and the hexagonal pin (H– figure 9)
Turn the sponge roller by giving it short and light presses (for-
wards and backwards as shown in figure 10) whilst holding
down the quick release device (H– figure 9), until it fits perfectly
into the hexagonal notch of the roller.
Move to the side opposite the motor casing.
Fit the quick release device with its cylindrical pin (F– figure 8).
IMPORTANT: QUICK RELEASE DEVICES (F/H – FIGURES 8/9) MUST FIT PERFECTLY INTO
THEIR HOUSINGS.

Cleaning the tank
BEFORE PERFORMING ANY OPERATION, MAKE SURE THAT THE MACHINE IS UN-
PLUGGED.
Shift the lever (A) to its upright position (figure 2 – page 6).
Raise the water conveyor belt and remove the tank (figure 11).
IMPORTANT
Any material drawn up from the floor deposits in the tank
on the rear side of the machine.
The layer of material that builds up must never be thicker than 2
cm, in order to prevent it blocking the water conveyor belt.
Washing the sponge roller
After cleaning the tank and filling it with cold and clean water, shift the lever (A) to its upright position to raise
the sponge roller off the floor (figure 2 – page 6).
Operate the power switch and with the machine running lower the lever (A) (figure 3 – page 6) and raise it
after 30 seconds.
Repeat this operation several times until the sponge roller is perfectly clean.
When the machine is in rest position, to prevent the sponge roller warping make sure the latter is raised off
the floor and that the lever (A) is in its upright position (figure 2 – page 6).
STORING THE SPONGE ROLLER
Store sponge rollers upright.
Rollers with cellulose sponges must be kept in plastic bags.
Storing the machine
Wash the sponge roller (see “Washing the sponge roller” on page 9).
In the event of long-term storage, remove the sponge roller.
IMPORTANT: QUICK RELEASE DEVICES (F/H – FIGURES 8/9) MUST FIT PERFECTLY INTO
THEIR HOUSINGS.
MAINTENANCE
BEFORE PERFORMING ANY OPERATION, MAKE SURE THAT THE MACHINE IS UN-
PLUGGED.
Grease moving parts on a periodic basis:
chain, bearings, wheel axle, belt tightening rollers.
FIG.11
IMPORTANT: FOR WASHING USE ONLY WATER. ALCOHOL OR DILUENTS MAY CAUSE THE
SPONGE TO DETACH FROM THE ROLLER.

ing screws.
Fit the new plugs making sure that the long side is facing to-
wards the tank.
