If your robot is not spraying paint it might be due to clogs in the spray system. If you have already tried cleaning the system using the cleaning guide, the following might help you deal with any clogs. While the spray system is fairly simple it has multiple components, so the first step is locating which component of the system is clogged.
Pump Clogs
Clogs appearing in the pump might be due to thick paint.
- Attempt to thin the paint in the pump by forcing water through it by pouring warm water down the intake tube until the water has had a chance to dilute the paint in the pump head. DO NOT USE PAINT THINNERS! Paint thinner can cause the rubber diaphragms in the pump to become brittle and damaged.
If the above-mentioned step does not work, cleaning the pump head might be helpful.
- If the paint has dried, then manual cleaning may be necessary to restore liquid flow through the pump. Click the link below for instructions on how to clean the pump. Be sure to remove ALL paint from the diaphragms for the best results. How do I clean or replace the pump head diaphragm?
Valve Clogs
A clog in the solenoid valve might be caused by old paint.
- Be sure to check the manufacturing date on unopened paint containers and inspect already opened containers of paint for any signs of contamination (e.g. lumps or a bad smell) to prevent future clogs.
- Dried bits of paint can lodge along the valve pin. If this happens the pin will jam, and the solenoid valve will no longer be able to control the direction of paint flow. This can result in the robot being unable to spray or unable to stop spraying.
If the above-mentioned steps are not helpful a burn test might be useful.
- If you don’t have access to the “Burn test” call support for guidance.
- A “Burn test” is a series of impulses designed to dislodge coagulated paint out of a system. To access the burn test, tap on the gear icon (
) in the top left corner of your tablet next, then select “Calibration Tools” ( in blue text). Next, choose “Burn test” from the options on the screen. Finally, set the OFF and ON timers to 2.0-sec intervals and tap “Start Pump Test”.
- Allow the “Burn Test” a few minutes to dislodge the stuck particles.
If the burn test did not remove the particles, then a manual cleaning may be necessary.
- If this is the case please call support for further guidance.
Nozzle Clogs
If the clogs are present in the nozzle, take the following steps to clean it.
- Put the intake pipe into hot water and place the blue return hose in a residual container.
- Press the yellow button located on the robot to run water through the system.
- Press the blue button to rinse the nozzle, alternating between pressing the buttons a couple of times
If no water passes through to the nozzle at all or the above-mentioned steps does not help, the nozzle itself can be cleaned.
- Remove the nozzle by twisting its housing counterclockwise.
- Dismantle the nozzle into its 4 components: housing, nozzle, gasket and filter. If the filter is not found it might still be in the outlet tube.
- Clean the parts separately using warm water and a soft brush. Reinstall them in the machine.
Clog in the intake line
If there is a clog somewhere across the intake line, it is likely centered around the filters. If so, the following might help resolve the problem.
- Clean the inlet filter and rinse it with warm water. Check if there is any visible blockage of the intake.
- If this doesn't help, open up filter housing further up the pipe. Clean the filter and the inside of the filter housing.
- If this does not help and the clog is believed to be somewhere else in the line, replace the tubing.
If none of the steps above solved the problem please contact support. The contact information can be found here.
