Hi, I've been using the irobot Rooma560 for 2 yrs. Great machine. It is charged 24/7 and it works Mon to Fri on self timer. Hardy machine (mine looks abused now). The "towers" are very good for setting the cleaning boundaries when needed. Still using the same battery. We upgraded to the bigger bin after 1.5 yrs. The suction is better although we were actually quite happy with the original bin size. My friend who hardly charged hers had problem with the charger shortly after she bought it. So I guess best to just leave it charged all the way. We are quite diligent in our weekly robot cleaning which is not a difficult task. Hope these info helps.
