iRobot Roomba 780: eficiencia de limpieza

[dragonflyeify]

Had a look at the 531 (90g) versus 581 (94g) versus 780 (97g). Seems that despite a higher pick up rate, the 531 and 581 appear to attack the dirt more directly and quickly whilst 780 appeared to move around like a headless chook leaving messes half picked before coming back to finish up, running around a lot more and presumably using up more energy. Was I mistaken?
