Mint R4200 won't start cleaning

It powers on, but when I press one of the cleaning mode buttons, the middle light turns on solid red and it beeps three times, then the left blue light flashes continuously.

What should I do to fix it?

Hi,

I found this on a PDF files that I found online:

If the red light turns off after the 3 beeps, but occurs again when you press the
Sweep or Mop button, Mint Plus is not ready to clean due to an activated sensor.

Check to make sure:
-Both ends of the cleaning cloth are securely tucked into the blue gripping strips
or onto the Pro-Clean velcro strips and the cloth is not bunching up.

-The cleaning cloth is not in the middle channel of the removable
cleaning pad.

-The removable, magnetic cleaning pad is firmly reattached to Mint Plus.

You can find the user manual here.

Hope this helps,

Yeah, I saw that info earlier and it didn’t see to help, but it did eventually start working again. I suspect that water got in it and that may have caused the issue.
