Is one an older brand?
From my understanding there is a:

With more advancements and improvements, Roomba Discovery features dirt detect, a self-charging Home Base(TM) and an Advanced Power System that makes this the finest robotic floorvac on the planet. And theres still a lot of planet left to clean.

I have an iRobot Roomba that is less than 2 years old. (Pretty basic model.) Recently it no longer wants to run. At first it would run for 30-60 sec then stop and give me a tone. Now its just giving me the tone as soon as I hit clean. The tone sounds unfamiliar to me (not the normal “uh oh” tone) – the tone is low-high-high-low. There are no beeps after the tone plays. The clean light is green until it gives me the tone then it blinks red. I have cleaned out the brushes and emptied the bin and the filter part. The wheels seem fine. I really cannot determine what could be wrong. Does anyone have any ideas or has experienced anything like this?
