Alright...so let me first say that I am very appreciative of all the feedback and assistance I've been given. Everyone has truly been helpful. Second, let me apologize for being so needy! I am not so mechanically inclined, and although reasonably intelligent about other things, these types of gadgets aren't my strong suit.
In my previous posting regarding the bushing/coupling:
http://www.roombareview.com/chat/viewtopic.php?t=9295
I thought the clacking sounds were due to the loose rubber brush and worn coupling. I cleaned out the brushes thoroughly, put a little silicone on them to lubricate (it's all I had besides 3-in-1 oil which I thought would be too sticky and only attract more debris) and tried out the Roomba again. When I tried it out, I just set it on the floor without the dust bin attached, clacking sound was gone. Yea, I thought. So I put the bin back in and set the Roomba loose, clacking sound was back.
So, the new novice hacker in me decides to open up the dust bin and fish around, thinking that maybe there's a loose piece of something in there causing the noise. The only discovery I made was that the fabric part of the filter had come loose from the plastic frame, just a bit on the edge, and inside the fan case there are a bunch of these 'teeth' missing (see attached picture).
Best I can figure is that something substantial got sucked up inside the filter chamber, poked a hole in the filter, then tore up these little teeth on it's way out the back of the Roomba. There doesn't appear to be any other issue with anything in there, and I did not open the vacuum motor portion itself (the picture is as far as I went).
Do you think the missing teeth are causing the noise? What are the teeth for?
I truly have tried to be a good girl about Roomba-proofing my home, and I thought that I wasn't overworking him with the size of the rooms he's cleaning. Since I purchased the fella from Costco, I was "considering" exchanging him for a new one (I know, I know, BAD consumer, BAD....LOL).
Any thoughts?
Thanks again and again. :) |

Hello
I think, teeth broken for balancing the fan. |

So the broken teeth might be causing the fan to wobble, thus creating the noise?
:D |

Maybe, but unlikely.
Try to start your Roomba with dust bin, but turn off dust bin motor. |

| The 360 degree placing of the small pieces of plastic sticking up are there to aid in the balancing of the impeller and motor assembly. Different ones are broken off to balance the spin of the impeller. |

Okay, so those are supposed to broken off? Interesting....
Any ideas as to what might be causing a rattling/clacking in the dust bin?

| The only moving parts in the dust bin are the electric motor and impeller. Disassemble it and see if you can locate some debris that may be causing the problem. |

Will try that next. If I hold the dustbin and shake it, I don't hear anything. Doesn't mean there isn't something wedged in there that flaps around, I guess. Roomba is much quieter on our area rugs, and I don't wonder whether it's just rattling because things have loosened up all over during our week and a half use?
I'll let you know if I find anything when I go huntin'!
