beads stuck in JAWS

My Hayward Navigator cleaning system (better known as Jaws by the kids)has an obstruction in it. My kids were playing with beads(the mardi gra type) in the pool. Rules state that everything must be removed from pool after pool use. One string of beads were overlooked(so they say). Now I have minimum pressure which causes Jaws to creep along the pool floor. I've checked the filter before the pump, I've checked the navigator itself, and i've disconnected the pipes that lead up to the connector in the pool. Can anyone point me in the right direction for clearing up this blockage. thankyou in advance
