Not working

Hi, I had the bad idea of asking my robot vacuum to remove some salt that had fallen on the ground, but I guess it both washed and vacuumed the area. To make the long story short, the robot stopped working since then, so I removed it from the app and tried to reconnect it back, after I tried to clean it, dry it, unplug it. Now, it turns on, seems it's recharging, however it doesn't respond to the commands, and no voices comes out of it, so I can't reconnect it in the app. What do you think I should do? Trash it, bring it to assistance, anything else?
Thank you in advance.
