Abstract. Some peculiar symbiotic and symbiotic-like systems showing different levels of activity demonstrate occasional high-speed bipolar jets and/or centrifugal outflows. Recently, the existence of a new subclass of interacting binaries — propellers — was proposed. The supposed prototypes — CH Cyg and MWC 560 — are among the most intensively investigated now peculiar symbiotic binaries. We present some results concerning the high-velocity outflows in both symbiotic systems. Some parameters of the outflows in both systems are given.
