Smells

I couldnt figure out the smell when it was operating. I cleaned out every nook and cranny this thing had, even used my vacuum to suck out the suction compartment in the robot.
Then, i stuck my finger in it. Wet, mushy.. what the heck was this???
I had a baby bottle cleaner, shovednit in, wiggled and pulled. HORROR
Managed to use the crevice tool on my vacuum to suck it i to the hole where I used my fingers to pry it through the robots mouth..
A ginormous wad of wet, dog hair, a rottten blueberry and some unknown particles  
I am disgusted.
