    Comments about iRobot Caster Assembly:

    Not really sure if I'm rating the wheel OR the Roomba but I love, love, love my Roomba 650. However, the front wheel wore out within about six months with daily use and I'm not sure why.

    I do have some quite well-worn wood floors that are the dogs domain so likely not that smooth but it would be good for engineers to explore why this is
    happening. However, customer service was great in helping me get a replacement.

    So, we'll anxiously see how this new wheel holds up. I'd not let this stop me from purchasing a Roomba; it does get pretty heavy usage with pet hair and less than glass finish floors.

      Comments about iRobot Caster Assembly:

      I love my Iroomba. This is my second one. First one went to live with my daughter and she loves it.
      However, the caster & ball assembly wears out and the ball won't stay in it. You cannot use the Iroomba without that little ball. So I have to order several of them at a time. It needs a little better engineering.
