  I propose a scenario to account for the fast polar outflow detected to be
blown by Eta Carinae in 2000. The scenario accounts also for the lack of this
flow in 1998 and 1999. The scenario is based on the binary nature of Eta
Carinae. The collision of the winds blown by the two stars, in particular near
periastron passages, slows down about 5 per cent of the wind blown by Eta
Carinae, i.e., the massive primary star, such that it stays bound to the
system. I assume that most of this mass is accreted back through the equator by
Eta Carinae during apastron passage, when its orbital velocity is much lower.
The mass accretion rate of this backflowing material may become about 25 per
cent of the wind's mass loss rate near apastron passages. If the backflowing
matter has enough specific angular momentum it can form an accretion disk and
may lead to the formation of a polar collimated fast wind (CFW) on top of the
stellar wind.
