If you get a red triangle with the two tone beep, and no voice prompt, roomba 770 runs for a few minutes or just immediately goes to red triangle...if you have thoroughly cleaned moving parts and find no obstructions, you may have the problem I had that stumped me for a week. Remove the trash bin, with roomba upside down, and there are 4 silver contacts that connect to two metal tabs on the trash bin. Over time the contacts lose some of their contact pressure. Use needle nose pliers to slightly rebend them so they make good contact to the trash bin contacts. These contacts feed the vacuum motor inside the trash bin. That fixed mine.

I have the same buildup of very fine, powderlike, dust/dirt particles behind the mesh screen.

I do not doubt your technological explanation as to why/how this accumulation has occurred but there is another issue created by this buildup and an concern to go with it.

The issue is that this accumulation literally stinks. We have 4 cats and a dog which is likely why there is such an odor. There must be a way to remove this stuff.

The concern is that, after putting up with the stinky Dyson and the continued accumulation, the "dust" will eventually completely fill the space behind the mesh screen. When that screen is completely filled is the only solution we have is to spend another $600 for a new Dyson?

The Dyson is not your typical disposable technology that we often buy today. We chose to spend the extra $ for the Dyson because of the spirit cleaning of the unit. Had we known the unit would, within 6 mos., begin to stink and would likely need to be thrown away within two years we would have purchased a less expensive brand.

Since we have learned now that Dysons are stinky and disposable units we can run it under water, let it dry and hope for the best?

Someone gave me a Miele S558 with this exact problem and I fixed it by disassembling the power hose and cleaning the contacts, bend them a little bit so that they exerted more force onto the metal ring, and reassembling. The end of the hose that attaches to the canister had the worst connection and this end was the most difficult to disassemble (I actually could not disassemble it completely, just enough to pull out the contacts and cleaning/bend them). Check other answers for how to clean the power hose contacts for more details on how to do this, I'm just saying that cleaning them did fix my problem. Good luck!
