Let's begin right away by taking a look at the core differences between the two versions.

PRICE

The 770, being the newer version, is naturally more expensive. Depending on where you shop, there is roughly a $150 price gap.

DIRT DETECT TECHNOLOGY

The 655 employs Series 1 of the above technology, whereas it's younger cousin enlists the Series 2. In simple terms, the 770 uses optical and acoustic sensors in order to indentify the dirtier areas, which is more efficient than the Series 1, which only makes use of acoustic sensors.

FULL BIN INDICATOR

The 770 comes equipped with a handy "full bin indicator" which lets you know when it's time for the bin to be emptied. By comparison, the 655 lacks this.

PERSISTENT PASS CLEANING

Once again the 770 has another feature the 655 doesn't share and the persistent pass cleaning method revisits troublesome spots to ensure a deep clean is achieved.

REMOTE CONTROL

Somewhat of a necessity in today's world, sadly the 655 again falls short, whereas this feature is present for the 770.

BIN TYPE

As a change of pace, this is one area where the older generation trumps the newer model. The Series 1 bin, found in the 655 actually holds more dirt and is easier to clean than the Series 2 variant, found in the newer 770.

SIZE AND WEIGHT

The 770 is heavier and bigger than its older compatriot, which is surprising given that technology seems to move towards smaller products that are more densely packed with features.

After exploring the basic differences between the models, we decided it was time for us to try out these vacuums ourselves and compile our list of pros and cons, which is depicted below;

iRobot Roomba 770 Robotic Vacuum Pros and Cons

PROS

What we like:

  • Full Bin Indicator - A nice touch that saves time on manually checking to see if the capacity of the bin has been reached.
  • Dirt Detection Technology - It makes for a more efficient clean that properly picks up every grain, which is enhanced by the next point..
  • Persistent Cleaning Method - Building upon the dirt detection technology, this allows for a thorough clean.
  • Remote Control - It's simple, but saves time and makes things far easier

CONS

What we didn't like:

  • Series 2 bin not as good as Series 1 - We found that the bin for the 770 was not able to hold as much as the 655.
  • Larger than 655 - Personal preference in truth, but it was a little bulky compared with the older model.
  • No Extras - Brushes etc not present.

PROS

What we like:

  • Cheaper - A saving of around $150
  • Has Extras - Unlike the 770, this comes with extra side, bristle and rubber brushes (1 of each).
  • Series 1 Bin More Efficient - As explained above, we found this bin to be larger and easier to clean

CONS

What we didn't like:

  • Lacks Remote Control - It turned out to be a bigger deal than we imagined, but the lack of remote control, after using the 770 felt archaic.
  • No Full Bin Indicator - Again, spoiled by the 770, this lacking function
  • One Bumper - A big point, only one bumper being present ended up scratching hard wood at least in our case, which really caused concern.

Conclusion

irobot roomba 770 comparison

So which Roomba wins? Both of these iRobot vacuum cleaners will serve you very well. However, the 655 is beginning to show it's age somewhat, with outdated technology that holds it back in some cases. Although they're similar, sharing features such as the same operating and charging time (two and three hours respectively) the devil is in the detail and if you can extend your budget so out of , roomba 655 vs 770, opt for the 770.
