The correctly fitted 4 m safety rope can prevent the cleaning robot from falling to the ground freely in case of a vacuum loss.

As the cleaning robot holds onto the glass surface with self-generated negative pressure, there is a risk of it crashing if the power supply is interrupted.

When fully charged, the built-in emergency supply battery provides enough power for a period of at least 40 minutes to hold the cleaning robot in place on the glass surface by means of negative pressure.

The cleaning robot contains a Li-Ion battery pack.

Replacing the battery pack:

1. Disconnect the device from the power supply and remove the cleaning pad.

2. Open the casing of the cleaning robot by unscrewing the screws on the back.

3. Localise the battery pack.

4. Disconnect the socket plug connection on the device board.

5. Unscrew the screws of the battery pack cover and remove the cover.

6. Remove the used battery pack, insert a new one and connect the plug to the device circuit board.

7. Reassemble the device and ensure that no hoses or other components are crushed or damaged.

Information on disposing of the battery pack:

• Dispose of the battery pack at the end of its service life in accordance with the applicable regulations.

Information on transporting the battery pack:

The lithium-ion battery is subject to the requirements of dangerous goods regulations. The battery pack can be transported by the user in public traffic areas without any further restrictions. When shipping by third parties (transport companies), special requirements for packaging and labelling must be observed. Do not use the battery pack if the casing is damaged. Tape off open contacts. Pack the battery tightly and securely. The battery pack must not be able to move in the packaging.

Depending on the model, the scope of delivery and colour may differ (see packaging imprint).

The device consists of the cleaning robot and the remote control.

The remote control is used to control the device manually, select the cleaning mode and switch the voice output on or off.

The cleaning robot adheres to the glass surface to be cleaned via a self-generated vacuum and moves it down automatically.

6 spray nozzles distribute the cleaning solution precisely and evenly on the wiper cloth with the help of a pump.

Cleaning is carried out by wiping the moistened wiper cloth over the glass surface.

The device has various cleaning modes.

In automatic mode, the cleaning robot travels along the glass surface in overlapping paths and stops automatically when cleaning is complete.

The cleaning navigation system ensures that the glass surface is evenly travelled over and cleaned thanks to systematic route planning.

The position memory function ensures that the device automatically returns to the starting point for easy removal from the glass surface after cleaning.

In manual cleaning mode, the cleaning robot is controlled using the arrow buttons.

Operation requires a KÄRCHER microfibre cleaning cloth and KÄRCHER window cleaning detergent RM 503.

The device has various cleaning modes.

Single pass over the glass surface in horizontal movements.

Move across the glass surface in horizontal and vertical strokes, then polish and clean the edges.

Back and forth movements on a small surface.

Single pass over the glass surface in horizontal movements, followed by an edge cleaning.

Manual driving using the arrow buttons on the remote control.

The cleaning robot indicates various operating states and errors with voice output, light and signal tones.

1. Insert the hollow plug into the socket of the device / extension cable.

2. Tighten the screw connection firmly.

   ATTENTION

   Risk of damage

   If the connection is not properly screwed down, the power supply may be interrupted by the movement of the device and the device may fall uncontrollably after the emergency supply battery has been drained.

   Therefore, make sure that the power supply is screwed on correctly.

1. Mix the cleaning solution. To do this, pour the detergent concentrate into the filling bottle and dilute with water according to the instructions on the label.

2. Fill the tank.

   Note

   To maintain a stable air pressure, do not overfill the tank.

   ---

   

   1. Open the tank cap.

   2. ATTENTION

      Risk of damage due to liquid intrusion

      Cleaning fluid entering the ventilation openings can cause damage to the robot.

      When filling, make sure that no cleaning fluid runs into the ventilation openings.

      Fill the tank to max. 80% using the filler bottle.

3. Close the tank cap and press it on.

1. Place the wiper cloth straight and flat on the Velcro surface of the cleaning robot.

2. Ensure that the edge sensors and the belt drive can move freely and are not covered by the wiper cloth.

1. Remove any objects that protrude into the movement area of the cleaning robot and could hinder its movements.

   Obstacles can be,e.g.:

   • Curtains and drapes

   • Objects on windowsills

   • Window handles

   • Window pictures and stickers

   • Fasteners attached to the glass surface or adjacent framee.g. such as suction cups or hooks for net curtain rods etc.

2. Check the glass surface for heavy soiling, such asdried bird droppings or thick pollen buildup.

3. Pre-clean heavily soiled glass surfaces.

   Note

   Allow the pre-cleaned surfaces to dry completely before attaching the cleaning robot.

Ensure that the movement space of the cleaning robot is not restricted during operation.

The movement space can be limited by, for example:

• Shutters and blinds lowered accidentally or automatically

• Adjacent hinged or sliding doors and windows opening or closing accidentally or automatically

• Windows, doors, curtains and drapes, etc., moving accidentally or as a result of drafts

1. Check the safety rope and carabiner hooks for damage and contamination before each use.

   1. Replace damaged parts immediately.

   2. Clean dirty parts.

2. Check the safety rope for knots and twists; remove them if present.

3. Attach the safety rope:

   ATTENTION

   Attach the safety rope so that it cannot get into the movement area of the cleaning robot. If the robot runs over the strap, it could detach from the glass surface and fall down.

   ---

   

   1. Loop the safety rope around a suitable, stable point (e.g. around window handles, curtain rail, table leg, wall or ceiling hooks).

   2. Hook the carabiner hook into the safety rope and tighten the safety catch.

   3. Attach the second carabiner hook to the loop on the cleaning robot and tighten the safety catch.

      WARNING

      Always tighten the safety latch, otherwise the carabiner hook can come loose from the cleaning robot during various movements.

      Note

      If no suitable fixing point is available, the safety rope can also be clamped in the window. To do this, open the window, clamp the safety rope at the top and bottom and close the window firmly.
