I have had some issues with my navigator not cleaning well.
I replaced the feet and wings and found a piece of a clothes pin was jamming up the water wheel. So everything should have been fine but now it goes very, very slowly, but then takes off like a John Force Funny Car, then either slows back down or just stands still.
It has steady suction, but slow, jerky movement. Any idea what could be causing this or what I should look at next?
Thanks for any suggestions!
