When the built-in diagnostics leads to the need to check the
appliance internally, please follow below steps to bring the
appliance to a service position.
- Before opening the appliance, first remove the dustbin cover
(3) and dustbin assembly (5-8).
- Remove the two screws (A) in the top cover, see picture
below:

- Turn the appliance upside down on a clean protective mat
or sheet to prevent scratches to the top cover.
- Switch the appliance off with the main switch at the bottom
of the appliance.
- Remove the battery (12)!
- Remove the side brushes (11).
- Remove the 5 screws (B) as indicated in below picture
(one screw is located underneath the QC sticker):

- Turn the appliance around again and remove the upper
cover (18), take care of unplugging the button interface
cable (20) from the main board! Do not forget to reconnect
the interface cable to the main board when re-assembling
the upper housing!
Note: When there is no need to disassemble the bumper assy,
please leave it in place as the wiring routing is quite
complex, and would result in unnecessary time spent, as
all mechanical components can be reached when only
the main PCB is removed.
- Undo all connectors from the main board, apart from the
connectors connecting to the bumper assy (J7, J11, J14 and
J202). Unscrew the 6 screws (C) indicated in the picture
below. You can now flip the main PCB (25) over, to the
front, and access all internal components. Please mind the
main PCB when servicing any part of the appliance, as it is
a sensitive piece of electronics.

DISASSEMBLY- AND RE-ASSEMBLY ADVISE
- To remove the Vacuum motor including suction tube
remove the 4 screws (E) as indicated in the picture below.
Be careful not to damage the Case Duct Filter (30).

- To replace the brush belt (36), unscrew the screw (F)
holding the protective cap covering the brush belt in place.
You should be able to unscrew screw Fwithout removing
the Bumper assy. Turn the appliance upside down, remove
the Brush retainer (17) and Roller Brush (16), unscrew the
two screws (G) holding the Pulley Main Brush assy (38)
in place. You can now remove the brush pulley and brush
belt.

- To remove the Brush Motor assy (31) unscrew the screw (F)
holding the protective cap covering the brush belt in place.
Unscrew the four screws (H) holding the Brush Motor assy
in place. By lifting the back side of the Brush Motor assy
you slacken the tension on the Brush Belt, and you can slide
the Brush Motor assy out. Make sure that you transfer both
halves of the motor pulley and the C-clip to the new motor
correctly, noting the original orientation (Motor, toothless
part, toothed part, C-clip).
H 4x
- To remove the Bumper assy, first undo the four remaining
connectors from the main PCB (J7, J11, J14 and J202) put
the main PCB aside. Unscrew the 5 screws (I) holding the
bumper assy in place, as indicated in below picture.
When removing the Bumper assy, take special notice of the
correct wiring of the different sensors, as the alignment of
the sensors is critical to the functioning of the appliance.
I5x
- To remove either of the two main driven wheel assy’s,
unscrew the two screws (J) holding the assy in place, and
remove the wheel assy. The protective plastic cap, sliding
axles and spring may become displaced, as they are not
(permanently) fixed to the assy. Please notice the location
of the spring around the front sliding axle, when reinstalling
the wheel assy.
Always check the correct position of the wheel assy with
respect to the Lifting Sensor assy (33) on either side, make
sure, when extended, it actuates the switch.
- When the repair is finished, check whether all functions
of the appliance work properly by running the built-in
diagnostics, confirming the functionality of all sensors and
motors. When everything works ok, perform a Sensor
Calibration and perform a quick functional test.

DESCRIPTION OPERATING PRINCIPLE
- The main board consists of the Power supply, CPU-board,
Real Time Clock, Motor drivers, Display and Camera unit
and thus is controlling the whole system with regard to
input/output processing, motor operation and others.
- The charging board charges the battery with the electrical
source supplied from the 19 V mains adapter and also gives
input to the control board regarding battery condition.
- The User interface board contains the interface buttons.
It also contains the Remote control reception device.
- 6 motors are used in the Robot body:
2 wheel motors, 1 main brush motor, 2 side brush motors
and 1 vacuum motor.
Sensors
- The Bumper sensor exists of an outer carbon rubber that
makes contact with an inner patterned film when colliding.
It is divided in 6 different contact areas, four at the front
and two at the front upper side.
- The Front IR sensors are placed to detect obstructions
without contacting, in addition to above bumper sensor.
A total of 7 IR sensors are mounted for this function.
- The Ground Detection IR sensors are placed in the bottom
to detect there is a “precipice”
-Wheel Lift Detection sensors are located on both wheels to
detect if a wheel is raised.
-ADustbin Detection sensor is mounted to detect dustbin
is in place.
-ACamera unit at the top cover is used for mapping the
room by means of the sealing/wall structure.
-APassive Encoder is attached to the front wheel to measure
the travel distance.
-AGyro sensor is mounted to measure the rotation angle.
