This contribution provides an overview of the systematic β-delayed fission (βDF) studies performed by our collaboration at the ISOLDE facility at CERN. Measurements of βDF properties of eight isotopes, including the first identification of this process for six of them, were carried out over the years. Systematic studies of fission fragment mass distributions, which led to the discovery of the new region of asymmetric fission and to identification of multimodal fission in several isotopes, are revisited. Motivation and description of the most recent experiments aimed at 178Au and neutron rich actinium and francium isotopes are introduced. The detection system used until recently as well as the two newly-developed detection systems are described.
