This contribution highlights three recent searches for supersymmetry with non-compressed spectra, using 138 fb$^{-1}$ of proton--proton collision data collected by the CMS experiment, at $\sqrt{s}=13$ TeV. The results include a search for R-parity violating supersymmetry in final states with single lepton, multiple b-quark jets and large-radius jets; an inclusive search targeting hadronic and leptonic final states with highly Lorentz-boosted objects; and a search for leptophobic Z' bosons decaying to chargino pairs in final states with two opposite-sign leptons and missing transverse momentum. No significant deviations from the standard model are observed, and stringent limits are set on a wide range of SUSY scenarios.
