The iRobot Roomba Series is among the best and most popular robotic vacuum cleaners in the world. They have been built with the best technology and features to guarantee the best vacuuming experience for long. Today, I am going to compare two of the Roomba cleaners, I.e the Roomba 770 and the Roomba 880.
The Roomba 770 Vs 880
The Roomba 770 is an older model while the Roomba 880 is the latest Roomba model. However, when you are shopping for them, you might hardly notice the difference between the two. These two Vacs are very different when it comes to performance. There are also a few features that they share. To fully compare these two vacuum cleaners, we are going to look at them in terms of technology. Here is how the Roomba 770 ranks against the Roomba 880.
Both the Roomba 770 and 880 have a low-profile design. With a height of only 3.6 inches, these two Roombas are all able to maneuver under furniture, beds and other low profile areas to ensure comprehensive cleaning.
Integrated iAdapt Responsive Navigation System
This technology automatically accounts for objects that are within the cleaning area. It helps the Roomba create an unobstructed path around this area for seamless maneuvering when cleaning. Both the Roomba 770 and 880 have this great feature.
3-Stage Cleaning System
Both the Roomba 770 and the 880 use the renowned iRobot’s 3-stage cleaning system. This technology includes agitation, brushing and high power suctioning to clean floors. The 770 uses the native 3-stage cleaning system while the 880 uses the more advanced AeroForce Performance Cleaning System that is more efficient and effective.
Dirt Detect Series II Technology
This technology, as the name suggests is for detecting where most dirt is. It uses optical and acoustic sensors to detect these areas. Once such areas are detected, the Roomba focuses on these areas and takes more time to clean them. Both the Roomba 770 and 880 have this technology.
High-Efficiency Particulate Air is a reliable and effective air filter that most vacuum cleaners use. Both the 770 and 880 have been built with this kind of filter for the best filtration. It can filter 99.97% of all particles larger than 0.3 microns
Brush System (Brush vs. Extractor)
While the Roomba uses brushes, the 880 brings on board a new technology, rubber extractors. These extractors are able to remove dirt and debris better than brushes. They also help transfer dirt to the bin more easily and reduces cases of tangled hair.
Spinning Side Brush
If you are a vacuum cleaner user, you might have realized that there is always some dirt that remains on the sides where the Roomba passes. For this reason, these two Roombas have been built with spinning side brushes to ensure they collect all dirt leaving no room for even a speck to escape. These brushes also clean corners and moldings where the Roomba can’t reach.
What I liked about these two cleaners is the schedule feature. With this feature, you can program the Roomba to start cleaning at your preferred times over a 7-day period. Once the set time reaches, the Roomba leaves the docking station and starts cleaning.
These two Roombas are compatible with physical remote control. On the remote, I was able to start it, change between different cleaning modes and even schedule cleaning programs.
Virtual Wall Boundaries and Lighthouse Capability
Many Roombas nowadays come with boundary technology that allows users to mark areas where they don’t want the Roomba to reach. Both the Roomba 770 and the 880 come with Virtual Wall Infrared Sensors that can be used to set up artificial barriers for the Roomba. However, the Roomba 800’s is a little bit more advanced. The Virtual Walls technology has been revamped and lighthouse capability included. This new addition allows multi-room cleaning. It also stops the Roomba from going to other rooms until it finishes cleaning one room.
Most vacuum cleaners have been built with anti-fall sensors to prevent them from falls. These sensors detect cliffs and signal the robot to change course. All the two vacs have this technology.
Self-Charging and Resume
Just like many other Roombas, the 770 and 880 boast of the self-charging and resume feature. Once the Roomba completes cleaning or detects low battery, it goes to the Charging base for storage or recharge. In the event that it had not completed cleaning, I realized that it resumed cleaning automatically.
These two vacuum cleaners have different battery technologies. While the Roomba 770 has a nickel-metal hydride battery while the 880 uses a new lithium-ion battery. One advantage of a lithium-ion battery is that it can be charged twice as many times as nickel-metal hydride batteries.
Wireless charging is a unique technology that has also been exploited in Roombas. The Roomba 770 comes with Wireless charging. iRobot offers a branded wireless charging kit with the 770 but this feature is not available with the Roomba 880.
Pros and Cons of the Roomba 770Pros
- 1. Wireless Charging – This is a unique feature that the Roomba 770 has and the later model, the 880 doesn’t have.
- 2. Low Profile Design – The Roomba 770 has a more low profile design compared to the 880. While the 880 stands at 3.6 inches, the 770 is only 3.4 inches.
- 3. Cheaper – The Roomba 770 is way cheaper than the 880.
- 4. Full Bin Indicator – The Roomba 770 has a full bin indicator that alerts homeowners when the bin is full.
- 1. Loud Operation – This robotic cleaner has a very loud motor that makes it emit a loud noise when cleaning. This is unlike the Roomba 880.
- 2. Average Sensors – The sensing ability of the 770 is average while the 880’s is perfect.
Pros and Cons of the Roomba 880Pros
- 1. Multi-Room Navigation – The Roomba 770 has no elaborate multi-room navigation system. It only has Virtual Walls while the Roomba 880 has multi-room navigation.
- 2. AeroForce 3-Stage Cleaning System – The 880 has a better cleaning system than the 770. This technology is called AeroForce 3-Stage Cleaning System which is an improved version of the 770’s 3-Stage Cleaning System.
- 4. 5x Stronger – The Roomba 880 is 5x stronger than the Roomba 770. It has more suction power and is able to suction even the smallest debris and particles.
- 5. Tangle-Free Debris Extractors – While the Roomba 770 sticks to brushes, the 880 uses tangle-free debris extractors that are more effective in cleaning, reduces tangling and helps take dirt to the bin.
- 6. Virtual Wall Technology with Lighthouse – The Roomba 880 has Virtual Wall Technology with Lighthouse. Even though the 770 also has this technology, it doesn’t have lighthouse capabilities.
- 7. XLife Battery – The Roomba 880 uses the Patented XLife Battery that is 2x stronger. Actually, while running my tests, the 770 went to its Charging base twice before the Roomba 880.
- 1. No Mobile Application – The Roomba 880 lacks Wi-Fi and App compatibility. This is a major concern for such a pricey vacuum cleaner.
Which One is Best; Roomba 770 or Roomba 880?
As you have seen, both Roombas have quite similar features and abilities. However, the Roomba 880 has more features and better performance. Actually, when reviewing them at home, I found the Roomba 880 to be more efficient and effective. The only problem is that its price tag is very high.
Bottomline – I would recommend the Roomba 880 for anyone who would meet its budget. However, if you are on a budget, the Roomba 770 is still a worthy purchase.
