  • Unnecessarily does repetitive cleaning on a certain sector, causing to lose batteries before it gets to clean other parts.

Comparison Guide Between Roomba 650 Vs 770

Between Roomba 650 and 770, the comparison just has made it pretty clear which one is better.


Roomba 650 vs 770 Performance
Roomba 770 wins performance wise and is much better at picking up dirt, dust, and hair without wasting too much time. Unlike Roomba 650 that might need a little tinkering on the system.

Despite the fact that we have been pointing out on this particular weakness, it doesn’t necessarily mean that 650 is bad. No. It is still a good robot vacuum cleaner that gets the work done fairly good enough and is good for owners who don’t own pets. It’s also good if your house does not have a lot of transitions of different flooring types.

Cleaning Abilities:

Roomba Cleaning

Roomba 770 excels in many things, starting from having a HEPA filter that prevents fine dust and allergen from going through. The problem with strong suction appliances is that they tend to get dust blown up around the room and you can’t even see it. Many people suffer allergic reactions to this, so HEPA filter is a must for you who don’t want to be sneezing all the time when the robot is on.

The HEPA filter makes Roomba 770 an excellent choice for pet owners, although both do good jobs at getting rid of pet hair. Both have their dust bin full at the time they are done with their work!

When talking about transitioning, Roomba 770 does a better job at that. There are cases where customers complain about their 650 not being able to clean a room with a rug that only ¼ inch high. While the full information is not disclosed, there are also customers who talk about having no problem using it on carpets that are up to one inch thick.


Price is also an important factor. 770 beats 650 at almost every part. This is the part where 650 wins in a sense. I am telling in a sense because when you count what you get in term of price paid, 770 wins again. To check the prices, check the buttons below.


Getting the Roomba 770 seems to be the obvious option to go with. It has a very smart design with easy to use buttons. Roomba 770 also comes with a remote control which allows you to turn it on without going close to the robot. It is also better at keeping the perimeter clean and above all, it is not priced that differently from the 650 model.


Roomba Self chargingSelf-charging and long lasting battery makes Roomba 770 better than Roomba 650. With a single charge, Roomba 770 can run 70 mins. But on the other hand, Roomba 650 only run for 50 to 60 mins maximum. Also, Roomba 770 is able to recharge by itself where Roomba 650 is unable.


The only thing the 770 loses in is that it has a six-month warranty while 650 has a one-year warranty.

Why Roomba 770 is Better then Roomba 650?

WhyIf we are to compare side by side, Roomba 770 wins. Let’s see why.

  • Navigation System: Roomba 770 comes with better iAdapt Navigation System. It doesn’t go through the same place over and over again (although we should praise how that really makes sure the area is clean). This saves a lot of power and makes sure that your robot gets its job done before it’s docked in. Whereas Roomba 650 has the problem of getting stuck in an area.
  • Built-in Virtual Wall: Both robots have a built-in virtual wall, but Roomba 770 has two, so you can mark more areas.
  • Size: Dimension-wise, both products are similar and almost identical. With only a few millimeters in different, Roomba 770 is 0.2 inches shorter, but Roomba 650 is 0.5 inches smaller. Aside from that, both will do great when cleaning under kick boards or other small areas.
  • Dirt Detect Technology: Both robots are equipped with Dirt Detect but Roomba 770 is equipped with Series II. Aside from the 3-stage cleaning process they both have, Roomba 770 does a better job at detecting debris and making sure no stone left unturned. That is how Roomba 770 boasts the ability to clean up to 98% of dirt and dust.
  • Tangle Free: Well, Roomba 650 does get tangled up from time to time, with 50:50 chance of avoiding or accidentally sucking in cords. Roomba 770 does do a better job at avoiding this, but it may still get tangled up. So, in comparison, you will still need to take them out of the way to prevent them from getting sucked by the robot vacuum.
  • Noise: The noise that a robot vacuum makes can really be distracting and scare your pets away. That is how we’d define the noise that Roomba 650 makes. It’s loud, no other way around that and a solution that we find interesting is by attaching a rubber door weather stripping. It won’t get in the way of the Roomba as it gets docked back.


Typically, in comparisons, each product has its own ups and downs and that’s what makes making a choice hard. We help our readers by pointing out the strengths of this product and why anyone would need it. Then, we compare it with the other and point out why other users might prefer this one. Well, this time, we could easily see which one is the better overall choice.

Roomba 770 was designed with fewer flaws that 650 possess. It has better dirt detection technology that cleans 98% debris and less of noise to make. 770 is also equipped with a fancy remote control, so you don’t have to get up of your seat to turn it on. Roomba 770 is also equipped with a HEPA filter that makes cleaning less of a mess.

On the other hand, AeroVac from 650 is enough for those of you who don’t fine vacuuming that much of a problem. It is actually pretty good in cleaning small area by repetitively going through those sections and keep the floor squeaky clean. Basically, a simple man without a pet will find using 650 to be good enough.
