Thank you for your considered response, Tom. Actually, the problem turned out to be much simpler than I thought -- and this should be a "heads-up" for the owner of any robot pool cleaner that has an electrical cord running from the transformer on land to the unit in the water.
Although some pool companies will make a big thing out of repairing these machines when they stop and start intermittently, the problem 99% of the time is the cord where it exits the robot. (I learned this from an unusually candid service technician.) With the constant twisting and turning of the machine as it cleans and the stress the pool owner puts it to when s\he pulls it from the pool, wires inside the cord become frayed and/or broken. (This is why the experts tell you never to wrap the electrical cord around a power tool.)
I simply cut about five feet of cord from the end that enters the robot and then rewired it. Usually there is more than enough cord to permit shortening. Presto! It works like new.
Again, Tom, many thanks for taking the time to respond to my query.
[BTW, all readers of this thread should know that Aquabot troubleshooting queries directed to the company head office is a total waste of time. They never even return your calls.]
