Roomba 570 problems
I decided it was finally time to try a Roomba so I got a 570 from Hammacher Schlemmer. It worked for about an hour total and then one of the wheel modules seemed to lose the ability to move in a forward direction. This made the Roomba turn in a tight circle until it gave up. There was nothing obviously mechanically wrong with the wheel module (it turned freely by hand) and when the Roomba tried to turn it the wheel did stiffen up (as determined by my hand). Maybe part of a bridge driver had failed? Anyway, Hammacher Schlemmer exchanged the whole package for a new one.
The second Roomba also worked for about an hour total and then started asking me to remove and clean its brushes. Which I did. Repeatedly. Peering underneath I could see that the brushes were not turning at all. I made one more thorough cleaning and made sure that the brushes rotate freely by hand. Still they do not run and Roomba asks me to remove and clean them every two minutes. I suspect the motor is just not getting power.
Am I having really bad luck or is this typical? Could iRobot have gotten a bad batch of power transistors? I assume I can get another replacement from Hammacher Schlemmer, though I don't know how many times they will pay the shipping...
