I Have Had My Carpet For A Yr Now. He Deflates To Rid Of Old Water. My Experience With Him Is If He Is Sticky Still Doing Fine. Mine Didnt Like To Much Flow So I Had To Move My Power Head. Is He Falling Apart. As Long As He Is Not Falling Apart Sill Alive. Just Have To Wait It Out. What Kind Of Carpet Is He. Sorry If My Writting S** I Write Whatever Pops In My Head At The Time.
