1. Design

In my opinion, the outside design is the most distinguishable characteristic between two or more objects. In particular, Roomba 650 vs 770 is different in the dimensions, weight, color, material type and shape.

Roomba 650.   This is a circular vacuum with the black color and some green on it. With the weight of 11.8 pounds, it’s quite lightweight and portable. To be honest, I’m genuinely fond of the eye-catching and elegant design of Roomba 650.

Roomba 770. From my view point, Roomba 770 is very similar with Roomba 650 in the outside design. Firstly, it’s also a circular canister vacuum. Secondly, it’s also in black color, but with some black buttons on it. Thirdly, the weight of 13.2 pounds is not considerably heavier than Roomba 650.

2. Battery and power

Roomba 650.  This model uses a yellow Advanced Power System Ni-MH Battery which helps keep the same runtime sustainable during charging times. Although compared to other robotic vacuums, Roomba does not have exceptional power, the suction and filtration are strong enough to clean all floor types, even for hardwood floors or pet hair.

Roomba 770.  Compared to Roomba 650, this model has more powerful suction and filtration. Moreover, the battery is good and the battery life is quite long. It takes 3 hours to recharge fully.

Roomba 650.  This vacuum uses 3-stage cleaning process series I. This programs allows it to clean all dirt, dust and debris from even the edges of things which the normal brushes can’t remove completely.

Roomba 770.  This product line uses 3-stage cleaning process series II. It means the cleaning program of Roomba 770 is more advanced than that of Roomba 650. Therefore, the power is much stronger than Roomba 650.

3.2. Dirt Detect and virtual wall

Both Roomba 650 and 770 have dirt detection technology whose function is to detect dust quickly during cleaning. The virtual wall keeps vacuum cleaning and avoid the should-no-crash places. General speaking, the dirt detect of Roomba 650 vs 770 is similar. However, while ROOMBA 650 has only ONE virtual wall, ROOMBA 770 has TWO VIRTUAL WALLS. As a result, Roomba 770 works more effectively and clean more clearly.
