Maintenance

It is important to take good care of your robot. Each subsystem requires certain Preventative Maintenance (PM) to keep them in good order. This schedule provides the manufacturer's recommended frequency for maintenance. The step-by-step instructions to complete this maintenance can be found in the Maintenance Section. 

Schedule

After long periods of use, the roller can become jammed. When that is the case, you simply need to disassemble it and remove any debris that is causing the jam. Additionally, the robot manufacturer recommends cleaning the roller out regularly (roughly every quarter) in order to extend the roller motor's lifetime. 

Instructions

Remove the Brush Roller

1. Turn off power to the robot with the switch located under the corner next to the battery compartment.
   

2. Remove the battery.
    

3. Turn the robot on its RIGHT side.

4. Locate the Roller at the front of the robot.
      

5. Loosen and remove the 4x screws using a Phillips 1 screwdriver. Set the screws aside.
   

6. Slide the Roller Retainers out and pivot them out of the way.
   NOTE - The retainers will remain attached to the robot.
   

7. Carefully remove the Full Brush Roller from the Intake.
   CAUTION - Make sure you do not drop the Inner Roller Core out of the Outer Brush while removing.
   

Disassemble and Clean 

1. Pull the Inner Roller Core out of the Outer Brush and set aside.
   
2. Look for any debris or hair around the outside of the Outer Brush. Remove any visible debris. Cut and remove any hair that has wrapped around the Outer Brush.
3. Locate the bearing on the far end of the Outer Brush.
   

4. Remove any hair or debris that is wrapped around the bearing. Make sure the Plastic Slider and the bearing can move freely. 

5. Check the bristles for any damage or excessive wear. If the bristles are damaged, replace the Outer Brush.

6. Check the Outer Brush for any cracks or damage. If the plastic is broken, replace the Outer Brush.

7. Set the Outer Brush aside.

8. Look for any debris wrapped around the Inner Roller Core. Remove any debris or hair.

9. Locate the bearing and O-ring in the Inner Roller Core.
   

10. Make sure the O-ring is seated properly into the groove.

11. Make sure the bearing can rotate freely.

12. Locate the Rubber Driver at the end of the Inner Roller Core.
    

13. Turn it slightly to make sure the Roller motor is still able to move.

14. Make sure the set screw on the side of the Rubber Driver is tight. If you need to re-tighten it, make sure the spacing matches the spacer jig as shown. Use a 1.5mm hex driver.
    

Re-assemble the Brush Roller

1. Slide the Inner Roller Core back into the Outer Brush. Make sure the Rubber Driver is properly aligned to the geometry inside on the roller as you slide it in. Be careful as you slide in the O-ring to make sure that the O-ring does not get displaced.
   

2. Insert the Full Brush Roller into the Intake. Make sure the sliders on both sides are aligned.
    

3. Pivot and slide the Roller Retainers into the Intake.

4. Tighten the 4x screws using a Phillips 1 screwdriver.
    

5. Place the robot back on the floor.
   

The roller is an essential part of vacuuming. The robot uses this part to disturb debris embedded in the carpet and vacuum it up. The robot has on-board diagnostics that trigger the Maintenance Screen (a picture of a wrench) when something is wrong with the roller. If the roller has been cleared of debris, these steps are a safe option for fixing other roller issues.

Instructions

Remove the Brush Roller

1. Turn off power to the robot with the switch located under the corner next to the battery compartment.
   

2. Remove the battery.
    

3. Turn the robot over so that you can access the roller(located at the front of the robot).

4. Loosen and remove the 4 screws using a Phillips 1 screwdriver. Take out the retainers. Set the screws and the retainers aside.
   

5. Carefully remove the Full Brush Roller from the Intake.
   CAUTION - Make sure you do not drop the Inner Roller Core out of the Outer Brush while removing.
   

Disassemble and Readjust 

1. Carefully pull the roller core from within the roller brush.
   
2. Unscrew the motor screw (located on the spider coupler end of the roller core) about half a turn.
   

3. Optional: If you have Loctite, completely remove the spider coupler screw and apply blue Loctite 242 to 3/4s of the screw and screw it back in. Otherwise continue to the next step.

Re-assemble the Brush Roller

1. Slide the roller core back into the roller brush. You may need to twist the assembly until the spider coupler lines up properly.
   

2. Check the the roller's fit with the bot. It should have a slight resistance against the side walls as it is being installed. If this is not the case, repeat the steps in Disassemble and Readjust until the proper fit is reached.
   

3. Re-position the roller retainers and screw with the 4 Phillips screws.
   

4. Flip the robot back over and you're ready to roll!
   
   

After long periods of use, the wheels might require maintenance. Tailos recommends inspecting and cleaning the wheels at least every 3 months in order to extend the lifetime of the wheel motors.

Instructions

Removing the Wheel Pods

1. Turn off the robot using the switch located under the corner next to the battery compartment and remove the battery.
   
   

2. Turn the robot on its side and unscrew the 2x Wheel Pod Retainers on each side of one of the Wheel Pods using a Phillips 1 screwdriver.
   

3. Set the Wheel Pod Retainers and the screws aside. Do not lose them.

4. Slide the first Wheel Pod out.
   

Inspection

1. Remove any visible debris or hair stuck within the wheel rollers. 

2. Push the Inner Motor Pod up. It should move freely and easily and spring back up when pushed. 

   • If the Inner Motor does not spring back up, or feels stiff or stuck, you will need a replacement Wheel Pod of the same orientation.

3. Try and shake the wheel up and down (toward the inner wall of the Wheel Pod).

   • If you are able to completely move the wheel back and forth, you will need a replacement Wheel Pod of the same orientation.

4. Inspect the rubber on the Wheels. Rotate the wheel so that you can get a good look at all the rollers.

   • If the rubber on these rollers is worn, you will need a replacement Wheel Pod of the same orientation.

5. Inspect the cable connected to the back of the motor. Make sure it is in good condition and not worn.

6. Inspect the inside of the empty Wheel Pod slot on the robot. The connector should be in good condition. If this connector is missing or damaged, contact Tailos Support.

Re-installing the Wheel Pods

Each Wheel Pod is marked with either L(Left) or R(Right). The position of the connector on the Wheel Pod indicates whether a Wheel Pod is L or R.

The wheels should be aligned to form a diamond using the direction of the wheel rollers shown in the image below. 

1. Re-insert the correct wheel pod into the slot carefully, making sure that the connector on the Wheel Pod lines up with the connector on the robot.

2. Align the 2x holes on the first Wheel Pod Retainer with the 2x holes on the robot body and tighten the 2x screws using a Phillips 1 screwdriver.

3. Align the 2x holes on the second Wheel Pod Retainer with the 2x holes on the robot body and tighten the 2x screws using a Phillips 1 screwdriver.

4. Repeat all the steps in this article for the remaining 3 Wheel Pods.

The Intake Skirt is a very important part and if it has a large tear in it, the robot will not clean as well. It is important to inspect the Intake Skirt regularly. If it has any large tears or if it is excessively worn, it is best to replace it. This will ensure that your robot is vacuuming as best as possible. 

Instructions

1. Turn off power to the robot with the switch located under the corner next to the battery compartment.
   

2. Remove the battery.
   

3. Locate the Intake Skirt.
   

4. Turn the robot on its side.
   

5. Make sure the intake skirt is properly mounted onto the screw heads and it is not disconnected at any point.

6. Look for any wear or tear on the Intake Skirt. If it is damaged, replace it using the procedure below

7. Unscrew all 11x screws using a P1 driver. Set these screws aside and do not lose them.

8. Remove the Intake Retainer. Set aside and do not lose.

9. Discard the old skirt.

10. Insert the skirt retainer into the skirt and align them together.
    

11. Take 1x 95911A118 M2 x 0.40 mm Thread, 8mm Long screw and align it with the outermost hole on the INT-P008, BDY-P056, INT-P018, and the intake. Tighten the screw. Tighten the screw using a P1 driver. Do not over-tighten. If the rubber starts bowing outward, then the screw is too tight. You should slightly loosen it.

    HALF CIRCLES POINT IN TOWARD THE ROLLER.

    

12. Take 1x 95911A118 M2 x 0.40 mm Thread, 8mm Long screw and align it with the OTHER outermost hole on the INT-P008, BDY-P056, and the intake. Tighten the screw using a P1 driver.
    

13. Now take the remaining 9x 95911A118 M2 x 0.40 mm Thread, 8mm Long screws, align with the holes and tighten them. Tighten the screws using a P1 driver.
