In　this　paper,　we　study　the　following　Lotka-Volterra　commensal　symbiosis　model　with　non-selective　Michaelis-Menten　type　harvesting　where　r1,　r2,　K1,　K2,　α,　q1,　q2,　E,　m1,　m2,　m3　and　m4　are　all　positive　constants.　Extinction,　partial　survival　and　global　attractivity　of　the　positive　equilibrium　are　investigated,　respectively.　The　results　obtained　here　essentially　improve　and　generalize　the　main　results　of　Baoguo　Chen　(The　influence　of　commensalism　to　a　Lotka-Volterra　commensal　symbiosis　model　with　Michaelis-Menten　type　harvesting,　Advances　in　Difference　Equations,　2019,　2019:　43).　©　2020　by　the　authors.
