Lowcost motor replacement in AeroForce Bin Roomba 8xx/960

First of all, excuse me for bad English. This is not my native language. The text is pretty big and I was too lazy to translate it myself, so I used Google Translator. :oops:

The "good" owner washed AeroForce Bin - the brushless motor was killed:

As far as I know, the motor is not sold separately. :cry:

And suddenly it seemed to me that the seat place of the motor is surprisingly similar ...:

... on the seat place of the Vacuum_Bin and AeroVac_Bin Roomba 500/600/700-series motor:

And really, voila! The old motor fits perfectly into new place! :shock:

But on this coincidence is not over!
Motor consumption (voltage 16V) in the dirty Vacuum Bin was 200 mA.
The consumption of a cleaned and lubricated motor is 135 mA,
Motor consumption in AeroForce Bin without filter - 620 mA,
Motor consumption in AeroForce Bin with filter - 550 mA!
Surprisingly - the same amount consumes the original motor! :shock: :shock:
The exhaust is subjectively also very reminiscent of the exhaust from the original AeroForce Bin. :wink:

AeroForce Bin with the old motor tested with different robots - works great!

PS: The current cost of the new AeroForce Bin in the official store is 55$!
