For years I've been using the aquabot to clean the inground pool. The bot is in need of repair so I'm trying to vacuum the pool but can't get suction from the hose. The skimmer has suction if I put my hand down to the hole but when I plug the hose into the skimmer hole, there is no suction at the other end of the hose. I've filled it with water but still no hose suction.

Any ideas what the problem might be? Pump is running just fine.

Thanks!
