iRobot Roomba 761 vs. 650 Comparison

Some of the differences are clear, but let us give you a more detailed and distinctive view of the two.


The 650 is a lot smaller and compact compared to the 761. It is 13.4 inches in length, 13.4 inches in width, and 3.6 inches in height; this gives it a much better advantage to get under furniture for a thorough cleaning.

On the other hand, the 761 is quite big in terms of dimension, measuring 21.5 inches in length, 19 inches in width, and 5.6 inches in height. This makes it not the most portable, but it is rarely a problem for a home cleaner, however.


As you can already guess, after the difference in dimensions, 761 is heavier than 650 by a significant 6.7 pounds or 3.1 kg! The 761 model is 14.6 pounds or 6.6 kilograms, which is quite heavy for a robot cleaner but not quite an issue.

The 650, on the other hand, is only 7.9 pounds or 3.5 kg. It thus adds to its portable and compact quality.

Dust Bin Capacity

One thing we didn't really touch on in our review is their dust bin capacity. They both have a moderate-sized bin to store the debris and dirt, but it needs cleaning after each cycle is complete.

The 761 has a dust bin capacity of 0.5 liters, whereas the 650 has a capacity of 0.47 liters. While yes, the 761 has a larger compartment than 650, it is not a revolutionary difference, but maybe it could mean something to you or others.

Battery and Power

The 761 Roomba uses a lithium polymer or Ni-MH battery, which charges faster, taking 3 hours or less. On the other hand, the 650 uses a lithium-ion or Li-ion battery that takes about 4 hours or more to charge fully. But, both last 3 hours maximum on a full charge.

However, when it comes to power, the 650 is a more powerful unit of 33 watts. And the 761 has 30 watts power. So it gives the 650 a better suctioning power than 761.
