Aquabot Bravo Repair Manual

I'm having problems with a recently purchased Aquabot Turbo T robotic cleaner--maybe someone has had a similar experience?
After about a month and a half of use, the cleaner has developed a clicking noise. The cleaner is also moving more slowly, and does not move horizontally along the waterline when it comes up to the top of the pool. You can imagine how I feel about this after using the thing maybe 10 times I have an inground gunite pool using chlorine.
The Aquabot people say this is probably due to a stretched drive belt. That confirms a description of the problem that I read in an Epinions review of the Aquabot, at least for the clicking noise. Has anyone else had this type of experience?
The drive belts are not under the year-long warranty--their expected lifetime is one season (3 months). That's certainly not something that I ever saw mentioned anywhere! After a lengthy and stubborn phone session, I did get Aquabot to send out a new set gratis, arguing that 1.5 months on a brand new unit was an awfully short time for a $1k piece of machinery to fail. They suggested that washing off the unit in fresh water after use, or even immersing it in fresh water, would help prolong the life of the components. That makes sense--I can't help but wonder why they don't include that little bit of helpful maintenance advice in the user manual or DVD.
