Errm, anyone knows if the 385 is supposed to come with a pump? Mine dosn't and the scooba is showing me the check tank light with uh-oh sound when start
Aiyoh, I'm out for few hrs & no time to reply, and I see so much speculation.
The pump accessory aka priming pump is really actually called "Scooba Suction Bulb":

This is not to be confused with Scooba pump mechanism, which is inside the machine & responsible for dispensing clean water on the floor.
For this exercise, I shall call the "Priming pump" as "Primer".
Queries:
1) Ur Scooba 385 is not missing the Primer, it's not suppose to have, even though the styrofoam has the slot for Primer, measuring cup & a large curvy hole for Clorox bottle to go.
That's right "Change soup don't change medicine", the mold for styrofoam box is recycled even though much of the packaging contents have changed.
2) So why some have Primer & some don't?
The Primer uses air to loosen the pump bladder, which tends to stick upon prolong non-usage. Think of a balloon, the inside is coated with powder, without powder, they stick.
Around 2007, iRobot improved pump design with self-loosening algorithm incorporated into the firmware, a corresponding modification to pump design is also required for self-loosening to work. Hence, Primer is no longer required.
3) Then why is ur 385 having "Check Tank" error?
(a) small problem & (b) big problem
I can guide u thru (a) over email or PM, my email is
unobliss@yahoo.com
If (a) doesn't work, u'll have to pass me to resolve (b). I have encountered (b) before for brand new Scooba 380 (ie. DOA).
THANK YOU China assembly workers! What doesn't kill me makes me stronger.
