Dehumidifiers, four of them

I have 4 of them, all for $60. They all work and throw the cold air out but DOES NOT extract water. All have a same problem. Frigidaire, both are 70 pints Vremi is 50 pints and Ge is 25 pints. All of them are clean but no idea what the problem is. I can also sell them foe $20 each. Please call or text 706-255-1721. Thank you
