There is a bad seal and/or gasket in the pump allowing it to leak. It is usally the seal. Take it to a local electric motor or pump shop and the repair is probably under $50 total. You could also buy the parts to try it yourself, but the seal that pump takes (AS-1000) is a little tricky to seat properly. Besides, if your bearings are also damaged, the shop could fix that as well.

I hooked up a new Polaris 280 pool cleaner to replace my Arneson Navigator and it doesn't move.

I would first take it out of the water and check for proper wheel RPM. If it is less than 28 RPM or you are getting no movement at all, it is going to be a problem with the power source. It is likely going to be that your booster pump is missing, malfunctioning, or is not installed properly on the pool cleaner. There are a few other things to check. Clean the skimmer, filter and pump basket, clearing any debris that restricts water flow. Check the hoses, connections and swivels for leaks. Try removing the blue restrictor disk from the UWF or if an adjustable gate valve is installed on the booster pump or cleaner line, open it completely so water can flow freely.

Polaris 280 flow is low and moving slowly with nosedive mnmc660 yahoo com is my email. seems like tale spray is fine but rear spray output and wheels turn slow resulting in nosedive. alkready checked...

Make sure that your skimmer, pump, and pool filter are clean and working properly. Your automatic pool cleaner can become sluggish if anyone of these features of your pool is not working correctly. Check all the hoses, connections, and swivels for leaks that could cause loss of water pressure. If it has been working poorly since you replaced the booster pump, you will also want to make sure that it is installed correctly. Finally, check your wheel RPM. It should be operating at between 28-32 RPMs. To do this, mark a single wheel side tire. Turn your pump on, hold the cleaner underwater and count the wheel revolutions for one minute. If you are under 28 RPMs, this might be your problem. To correct this, check your filter screen. I know thay you said that you have already done this, but this is typically the problem so I would check it again. Also, you can remove the blue restrictor disk from the UWF. If you booster pump has an open gate valve, open it completely to increase water flow. This will also help with your RPMs. If you try these suggestions and they do not work, let me know and I will come up with something else to try. Hope this helps you out.

Front wheels don't turn

It's probably a damaged drive gear. Polaris was at one time giving out free repair kits for this problem because of the poor design of the original.
