Thanks once again, Carl. You're a wealth of information! I do appreciate it. From now on I will turn off the filter when I use the sweeper and see how it works. It's a world better than the little cheapie that was here when we bought the house, so I still like the Aquabot...just those couple of issues that could be improved. I'll see if it changes with the filter off.

Happy Summer days to you! You're a great guy - spending your time helping people like me! Glad your old Dolphin is working well for your friend. It always feels better to pass along something to someone else who can use it, rather than let it end up in a dump somewhere!
