Purpose of Use and Features

The robotic vacuum cleaner is intended for cleaning various types of hard floors such as wooden or laminate floating floors, tiles, vinyl, etc. and carpets with a low pile height. While vacuuming, it effectively combines various routes to optimally clean the entire floor area.

• The suction hole effectively removes hair, animal fur, etc.
• The two side rotary brushes brush dirt out of hard-to-reach places along walls and furniture and out of corners.
• The motorised rubber wheels protect sensitive floors against scratching and can travel over threshold strips up to a height of 1 cm and ride on to a 2 cm high carpet.
• The suspended bumper enables the vacuum cleaner to dampen the approach to an obstacle and to efficiently clean around it. The infrared sensors in the front bumper prevent the vacuum cleaner from colliding with obstacles. Safe operation in rooms with stairs is made possible by the bottom anti-stair-fall sensors.
• Another advantage of the robotic vacuum cleaner is the mop function, which enables dry and wet wiping of smooth hard floor surfaces. While wiping, the vacuum cleaner vacuums small bits of dirt and dust from the floor to prevent the mop fabric from being excessively soiled during the cleaning cycle. When the vacuum cleaner finishes cleaning, it will automatically shut off the supply of water and thereby limit it leaking on to the floor.
• For easy identification of the operating state, the button on the cover has an indicator light the colour of which indicates low battery voltage, battery charging, full charge and operation, and others. Apart from the indicator lights, the vacuum cleaner also has audio signals that accompany certain functions or error states of the vacuum cleaner.
• The remote control facilitates convenient control, enabling the vacuum cleaner to be turned on and off, to be set to the automatic cleaning mode, to select an operating mode, to send the robotic vacuum cleaner to the charging station or to set scheduled cleaning.
• The vacuum cleaner is equipped with GYRO MAPPING function (orientation in space), which can identify the space geometry of a room in which it is cleaning, thereby the vacuum cleaner is able to better clean the floor. This is a built-in function and cannot be affected in any way.

Preparing the Robotic Vacuum Cleaner for Operation

Installing and Using the Rotary Brushes

The rotary brushes (A11, A15) are intended for smooth floor surfaces and ensure effective cleaning in corners, along walls and furniture.

• Turn the vacuum cleaner upside down. Gradually push the rotary brushes precisely and with force on to the pins that are intended for them. While doing this, make sure that the marks L and R both on the brushes and on the vacuum cleaner match. Turn the vacuum cleaner back over to the operating position.
• When using the robotic vacuum cleaner to clean rooms with carpets, remove the rotary brushes. When removing them, proceed in the reverse sequence to their installation.

Inserting and Removing the Battery

The vacuum cleaner is equipped with a Li-ion battery. If the battery is packed separately, it is necessary to insert it into the vacuum cleaner before first use. Use only the original battery type.

• Make sure that the vacuum cleaner is turned off with the main switch (A4). Turn the vacuum cleaner upside down and screw off the cover (A17).
• Remove the vacuum cleaner connector from the battery compartment. Connect the battery connector to it. The battery can only be connected in one direction.
• Screw the cover (A17) back on and turn the vacuum cleaner back over to the operating position.
• Remove the battery in reverse sequence. Prior to removing it, always check that the vacuum cleaner is turned off using the main switch. The fabric strips on the body of the battery make battery removal easier.
• When the vacuum cleaner will not be used for an extended period of time, take out the battery and store it in a dry, clean and cool place out of children's reach.

Location of the Charging Station

The charging station (B4) serves to automatically recharge the battery and the vacuum cleaner must have good access to it.

• Locate the charging station against a wall on a hard, even and dry surface within reach of a power socket. Make sure that there are no stairs or obstacles within a distance of 1 m on the left and right of the charging station and within a distance of 2 m in front of the charging station, that would prevent the vacuum cleaner from finding the charging station and docking successfully.
• Insert the power adapter plug (B2) into socket (B6) of the charging station, and insert the power cord plug into a power socket. Place the power cord in such a way that it does not tangle into the cleaning brushes of the vacuum cleaner.
• In the event that the vacuum cleaner is not used for an extended period of time, disconnect the charging station from the power socket and store it in a dry, clean and cool place.

Charging the Battery for the First Time

Note: Prior to charging the battery, the vacuum cleaner must be turned on using the main switch (A4).

• Before using the vacuum cleaner for the first time, it is necessary to fully charge the battery for at least 12 hours.
• Check that the charging station (B4) is correctly positioned and connected to a power socket according to chapter Location of the charging station. Turn on the main switch (A4) of the vacuum cleaner, grasp the robotic vacuum cleaner and manually place it into the charging station so that the charging contacts (A8) on the underside of the vacuum cleaner and the charging contacts (B5) on the charging station are connected. When the contacts are connected, the charging process will start.
• The robotic vacuum cleaner can also be charged without using the charging station. Insert the plug (B2) of the power adapter (B1) into socket (A3) of the vacuum cleaner, and insert the power cord plug into a power socket.
• During the charging process, the indicator light on button (A1) will flash pink.
• When the battery is fully charged, the indicator light of button (A1) will remain permanently lit blue and the process will end automatically. The robotic vacuum cleaner is now ready for use.

Selecting the Robotic Vacuum Cleaner Cleaning Mode

Before starting the cleaning process, check that the entry door into your apartment or house is closed. From the floor surfaces, remove clothing, paper, toys, power or extension cords and other items that the vacuum cleaner could suck in or catch. Lift curtains and drapes that reach to the floor so that the vacuum cleaner does not catch them.

Tip: When vacuuming in a new environment for the first time, carefully observe the movement of the vacuum cleaner. You can thereby recognise problematic obstacles and remove them for the next cleaning session.

• Automatic Cleaning Mode: Press button (A1) or button (C9) (ON/OFF) on the remote control. The vacuum cleaner will enter the automatic cleaning mode, in which it effectively combines various routes to achieve an optimal clean of the entire floor area. As soon as the vacuum cleaner finishes cleaning, it will seek out the charging station and dock there to recharge.
• Maximum Power Mode: Press button (C12) (MAX) on the remote control. The vacuum cleaner will enter the cleaning mode, in which it effectively combines various routes to achieve an optimal clean of the entire floor area. This mode is characterised by increased motor and central rotary brush power for the purpose of achieving the most effective cleaning process.
• Spiral Cleaning Mode: Press button (C10) (MODE) on the remote control so that the display shows MODE1. The vacuum cleaner will enter the spiral cleaning mode. Compared to the other modes, this mode is characterised by a lower speed of the vacuum cleaner and increased motor and central rotary brush power for the purpose of achieving the most effective cleaning process.
• Random Direction Movement Mode: Repeatedly press button (C10) (MODE) on the remote control so that the display shows MODE2. The vacuum cleaner will enter the random direction movement mode and will continue cleaning in this mode until the battery is almost flat. It will then end the cleaning process and seek out the charging station in order to recharge itself.
• Along-the-Walls Cleaning Mode: Repeatedly press button (C10) (MODE) on the remote control so that the display shows MODE3. The vacuum cleaner will enter the along-the-walls cleaning mode, in which it moves along the perimeter of the room and the motorised side rotary brushes sweep out the dirt along the walls and furniture corners to achieve a perfect clean. The vacuum cleaner will continue cleaning until the battery is almost flat. It will then end the cleaning process and seek out the charging station in order to recharge itself.
• Zig-Zag Cleaning Mode: Repeatedly press button (C10) (MODE) on the remote control so that the display shows MODE4. The vacuum cleaner will enter the zig-zag cleaning mode, which is suitable for effectively cleaning large areas without furniture present.

Pausing the Cleaning Process

Press button (A1) or (C9) (ON/OFF) on the remote control at any time during the cleaning process to stop the vacuum cleaner in the place where it is cleaning.

Using the Mop Unit

The mop unit is used for simultaneous vacuuming and dry or wet wiping of smooth floor surfaces. It consists of the removable dust container (D1), water tank (D2) and the mop fabric (D3). The water tank is equipped with an electronically-controlled water pump that automatically doses the water on to the fabric and also stops dosing water at the end of the cleaning process to prevent water from leaking on to the floor or the charging station.

Attention: Only use the mop unit intended for this robotic vacuum cleaner model. Do not use the water tank (D2) without the mop fabric attached. The mop unit is not intended for cleaning carpets.

Dry Wiping of Floors

Dry wiping is used for removing fine dust and floor polishing.

• If the mop unit is inserted inside the vacuum cleaner, press latch (A7) and slide the unit out of the vacuum cleaner.
• Attach the mop fabric (D3) to the underside of the water tank (D2) using the velcro zip (D4) on the water tank and insert the unit back into the vacuum cleaner.

Wet Wiping of Floors

Wet wiping is used for cleaning away minor dirt and floor polishing.

• If the mop unit is inserted inside the vacuum cleaner, press latch (A7) and slide the unit out of the vacuum cleaner.
• Slide the dust container (D1) out of the water tank (D2).
• Attach the mop fabric (D3) to the underside of the water tank (D2) using the velcro zip (D4) on the water tank.
• Open the cap (D5) and fill the tank with water. Properly insert the cap back in. Wipe any excess water off the water tank. Take special care to ensure that the contacts (D6) are dry.
• Note: For wiping, we recommend using clean water. If you use a cleaning agent, it may foam up and thereby worsen the dripping of the water on to the fabric, or potentially cause smudges on the floor after it dries.
• Insert the dust container (D1) back into the water tank (D2) and insert this assembly back into the vacuum cleaner.
• Start the vacuum cleaner.

Scheduled Cleaning

Note: The scheduled cleaning time setting is based on the system time set on the remote control. Therefore, before setting the scheduled cleaning time, it is necessary to correctly set the system time as described in chapter SETTING SYSTEM TIME ON THE REMOTE CONTROL.

This function is used to set a time, when the vacuum cleaner is to start automatic cleaning. The vacuum cleaner will then start cleaning at the same time every day. If you use the application, it is possible to schedule a cleaning time for every day at a different time. Please follow the instructions in the application.

Setting Scheduled Cleaning using the Remote Control

• Hold down button (C3) (PLAN), until the time setting figures start flashing (hours and minutes).
• Use buttons (C5) [up arrow] or (C8) [down arrow] to set the time values. Toggle between the hour and minute numbers using buttons (C6) [left arrow] or (C7) [right arrow].
• Confirm the set time by pressing button (C9) (ON/OFF). When confirming, the remote control must be pointed at the vacuum cleaner. The vacuum cleaner will confirm the scheduling via a voice message: “SCHEDULING CONFIRMED”.
• Note: Please keep in mind that the set value is not the time when cleaning will start but rather the time by which the start of cleaning is delayed relative to the current time. Therefore, if you set, for example, 02:30 at 8:00 a.m., then cleaning will be started after 2.5 hours, i.e. at 10:30 a.m. every day.

Cancelling Scheduled Cleaning using the Remote Control

• Following the procedure described in the paragraph above, set the time value on the display to 00:00 and confirm the value by pressing button (C9) (ON/OFF). When confirming, the remote control must be pointed at the vacuum cleaner. The vacuum cleaner will confirm the scheduling via a voice message: “NO SCHEDULING”.
• The scheduled cleaning can also be cancelled via the smartphone application.
