Fairy-Max confirms the given position is mate in 4. It prefers a slightly different line:

In general 3-vs-1 end-games are very easy once the bare King is trapped in a corner (say resticted to a1-b1), You just approach with your second piece, and position it for the kill. The 3-vs-1 checkmating applet discusses what the requirement for the pieces is to be able to make that final kill. In this case it is even easier than usual, because the Wazir-Maos are so powerful that there are already checkmate positions that do not even need the white King. (Like the one Fairy-Max ends up in.) These can provide additional threats next to the normal patterns.
The hard part is usually to get the King in that corner.
