The lower hose may be cracked and loosing suction.
Just checking, do you pull the handle on the inside of the handle? That releases the water. Sometimes, it takes a couple squeezes to prime .
Your Floormate will be okay. I've accidentally done it myself, more than once. I've owned my Floormate for about 5 years and that's with constant use.
