  The Coulomb drag effect has been observed as a tiny current induced by both
electron-hole asymmetry and interactions in normal coupled quantum dot devices.
In the present work we show that the effect can be boosted by replacing one of
the normal electrodes by a superconducting one. Moreover, we show that at low
temperatures and for sufficiently strong coupling to the superconducting lead,
the Coulomb drag is dominated by Andreev processes, is robust against details
of the system parameters and can be controlled with a single gate voltage. This
mechanism can be distinguished from single-particle contributions by a sign
inversion of the drag current.
