The mowing time is very short (Short Run Time). What should I do?

This article contains the following sections:

 

 

For RC, TC, MC models

Q1 . Did you observe this error more than once lately?

If Yes – Proceed to Q2.
If No – Press the ‘OK’  button for 3 seconds and set the time and date. Put the robot at the Base Station. The robot will now be charged a long charging session up to 16 hours.

 

Q2 . Check the mowing duration by pressing the settings button for 3 seconds, enter P106. The first number to the left shows the number of the operation in the list, and the rest of the numbers is a counter of that operation in minutes. Review of the operations list can be done via the Left and Right keys.

Does the mowing duration is indeed shorter than expected?


If Yes – Proceed to Q3.
If No – Everything seems to be OK.  Call Robomow Hotline for further analysis.

Q3 . Is the mowing height set too low, and is the grass height high?

If Yes – Increase the mow height and let the robot complete full mowing cycles (2-3 days) to understand if the problem is resolved or still exists.
If No – Proceed to Q4.

 

Q4 . Turn the System Switch to Off , lift the robot from its front area and check the following:

  • Debris is not stuck in the mowing deck.
  • Blades are not bent.
  • Too many mulches are built up between the mowing deck and blades.
  • Rotate blades (using a long stick or gloves).

Was any of the above observed on the mowing deck?

If Yes – Make sure the mowing deck is clean and the blades are in good condition.
If No – Proceed to Q5.

 

Q5 . Turn the System Switch to ON, Enter Power Box to Pause mode (by pressing the On/Off button on the Power Box for 3 seconds), place the robot on the Base Station, and let it charge 12-16 hours. Does the full battery icon turn constant green?
If Yes – The robot needed a long charging session, which happens once in a while. Let the robot continue working and contact Robomow Hotline if the problem persists.
If No – Battery Pack should be replaced.
