iRobot Roomba 680 vs. 690: Robotic Vacuum Comparison

Nowadays, it’s not uncommon to find robots doing the work that humans never wanted to do. In the past, it was just robot workers doing meticulous shaping, cutting, and welding work in factories, but today, robots have found a purpose in our homes. In numerous households across the world, robots have taken over the arduous tasks of sweeping and vacuuming floors. We couldn’t be happier.

In this article, we’re going to take a look at two popular robot vacuum cleaners from one of the most infamous home robot producers in the world – iRobot’s 680 and 690. At first glance, you might think that due to their similar model numbers, there would only be minor improvements in the Roomba 690 robot vacuum compared to the older iRobot Roomba 680, but you couldn’t be more wrong. Today, we’re going to compare both of these iRobot models and determine which of the two offers greater value. Let’s get started!

HEPA Filter

680
The filter used in robot vacuum cleaners capturing and retaining super-fine dust particles. Particles such as pollen, pet dander, and microscopic bugs may require a HEPA filter to prevent from going airborne. Unfortunately, the 680 is not compatible with a HEPA filter. Instead, it comes with another filter that works fine, but it’s just not as reliable as a quality HEPA filter.

690
The iRobot Roomba 690 robot vacuum cleaner uses a HEPA filter, giving it a super-efficient filtration system that captures and eliminates up to 99% of particles as small as 0.3 µ. If you have allergies, you will appreciate any vacuum cleaner that utilizes a HEPA filter, including the 690.

Conclusion: You can never go wrong with a HEPA filter in place. However, if you do not suffer from any allergies, then you could get by with the 680. For everybody else, the 690 is the way to go.

Wi-Fi Connectivity and Smartphone App

680
Having a robot vacuum that can connect to your home’s Wi-Fi router and has a downloadable app for your Smartphone is great for several reasons. First, you don’t need to constantly stand up and press buttons to get your robot started. Second, you can command the robot to begin vacuuming from anywhere in the world with an internet connection. Unfortunately, the 680 doesn’t give its users this convenience.

690
Meanwhile, the 690 doesn’t just have Wi-Fi connectivity capability, but it also takes commands from virtual assistants such as Google Assistant and Amazon Alexa. Simply give it voice commands through these services and your robotic vacuum will begin to work.

Conclusion: It’s more a convenience than anything else, but what’s the point of getting a robot vacuum cleaner if you aren’t looking for convenience? The 690 is the clear winner here. The 680 still requires you to press buttons to schedule cleaning times manually.

Recharge and Resume

680
There will come a moment in time where you will direct your robotic vacuum to begin its cleaning cycle, only to have the low-battery indicator beep at you. When this happens, the 680 will automatically return to its charging dock and refuel. However, when the battery’s full, the 680 will not resume where it left off.

690
Just like the 680, the 690 will return to its charging dock to recharge its batteries, but it won’t resume its cleaning tasks. Fortunately for its users, you can control the robot remotely using either Google’s or Amazon’s virtual services to direct the robot to continue where it stopped.

Conclusion: We would have loved it if either of these models had a resuming feature, but as they are, we feel that the 690 with its Wi-Fi connectivity and remote controllability, sending commands to the robot to resume work is super simple. As for the 680, it’ll wait for you to get home before getting back to work.

Carpet Cleaning Capability

680
Most robot vacuum cleaners perform flawlessly on hardwood floors and tiles, but the true test is cleaning carpets and rugs. The 680 is designed to be used exclusively on smooth surfaces. Its brushes and suction power are incapable of cleaning even the thinnest carpets ever.

690
The 690 also doesn’t come with a carpet boosting feature, but its brushes and suction power allow for cleaning thin carpets when needed. Just let the 690 roll over your carpets to pick up microscopic organisms from one of their favorite hiding places.

Conclusion: If your home or room doesn’t have carpeting or shaggy rugs, either of these robot vacuums will work well. However, if you need to constantly pick up pet dander, dust mites, and dirt particles from a thin rug, between these two iRobot models, the 690 would be the better choice. Just remember that there are other robot models that are better equipped to handle carpets than the 680 or the 690.

Virtual Wall

680
A virtual wall is a barrier that prevents the robot from passing through. If you want your robot to one room specifically without wandering into the next, place the virtual wall near the location and your robot will not pass the invisible laser. This is a handy feature if you want to do a little bit of spot cleaning. Too bad the 680 doesn’t have it.

690
The 690 does, though. You can prevent the 690 from wandering too far away from where you want it to clean without having to modify any configurations.

Conclusion: Surprise, surprise, the 690 comes with a feature that the 680 doesn’t. Setting up virtual walls is important if you only need a specific room clean (e.g. your room, not your sister’s). The 680 doesn’t think like that and is fair to everybody.

Roomba 680 vs 690: Bottom Line

At the end of the day, it’s clear that the improvements implemented in the upgraded 690 model of the Roomba make it much better than the outdated iRobot Roomba 680 robot vacuum. First of all, controlling the robot is super convenient. With the use of a Smartphone and the downloadable app, you can command the robot to scheduling vacuuming tasks, where to vacuum, and set up invisible barriers that the vacuum cleaner won’t pass.

You can also use Google Assistant and Amazon Alexa to tell the robot what to do and when. It also has better carpet-cleaning performance, though it’s far away from being the best carpet cleaner robot out there. If you’re still on the fence on whether to get the 680 or the 690: do yourself a favor and just go with the iRobot Roomba 690 robot vacuum cleaner.
