The effect of solar wind on dust particle, meteoroid, is investigated. Rotation of the particle is also considered. Detail derivations of both equation of motion and Euler's dynamical equations, are presented. The most simple form of the action of the solar wind is considered and the derived equation of motion reduces to "pseudo-Poynting-Robertson effect" for non-rotating spherical particle. The final equation of motion contains also angular velocity term and it may cause change of orbital plane of the meteoroid. Analysis of the Euler's dynamical equations shows that rotational axis of the meteoroid changes in time and equilibrium state for the orientation of the axis of rotation does not exist for spherical particle.
