What Does The iRobot Roomba 690 Offer?

Right off the bat, you’re going to notice that the iRobot Roomba 690 looks just like a regular robot vacuum cleaner, and it comes with all of the conventional accessories. But, it also comes with something else. An unusual device that many robot vacuums don’t offer.

What Does The iRobot Roomba 690 Offer

iRobot has included something known as a “Dual Mode Virtual Wall Barrier”. A Dual Mode Virtual Wall Barrier is a small object that you place in front of a doorway or in front of an exit/entrance. When you do this, the Dual Mode Virtual Wall Barrier emits a signal that then tells the iRobot Roomba 690 not to pass.

If you want the iRobot Roomba 690 to stay out of one particular space, then this is a fantastic tool! Or, if you want the iRobot Roomba 690 to stay within a particular space, so that it’s forced to clean it thoroughly, then it’s also a fantastic tool!

iRobot Roomba 690 Review

To use the iRobot Roomba 690, there are two options. You can use the remote control, which gives you direct access to the features of the robot vacuum. But, you must be within a certain radius to use the remote control. That’s why you can also use your smartphone.

Using your smartphone, you have direct access to features such as scheduling, accessing the different cleaning modes, telling the vacuum to recharge, and turning it on at any time and any place. It doesn’t matter if you are miles and miles away, because using your smartphone gives you direct and immediate access to the features of this robot vacuum.

When the iRobot Roomba 690 is moving across the floors in your home, there are two key technologies being utilized. The first technology is that of “Dirt Detect”. Dirt Detect consists of multiple sensors that detect the dirt and dust on the floor, as well as how to move across the floor to remove that dirt and dust. Then, the second technology is the 3-Stage Cleaning System.

The 3-Stage Cleaning System is a cleaning system that involves sweeping up the dirt and dust that is around the vacuum. Then, this dirt and dust is lifted into the main suction pathway, using the brushes that are on the bottom of the vacuum. Right after that, the suction is used to bring all of the dirt and dust into the vacuum, where you can then dispose of it.

For a total of ninety-minutes, you can use the iRobot Roomba 690 without needing to recharge it. When it’s time to recharge, the vacuum goes back to the charging dock, automatically.

Ultimately, the iRobot Roomba 690 is a robot vacuum that contains all of the wonderful features you would want in a robot vacuum. It’s an affordable robot vacuum that gives you the basics, and the basics are executed and refined to perfection!

What Does The iRobot Roomba 891 Offer?

In comparison to the iRobot Roomba 690, the iRobot Roomba 891 doesn’t offer very many features, or attributes, that would appear to be unique or different. If you look at what the iRobot Roomba 891 includes, you’ll notice that there is no Dual Mode Virtual Wall Barrier.

Roomba 891

Even though it doesn’t include a Dual Mode Virtual Wall Barrier, and doesn’t seem to offer many unique features, the iRobot Roomba 891 is an excellent robot vacuum in of itself.

When you are using the iRobot Roomba 891, you’ll notice that the basis functions are the same as the iRobot Roomba 690. Through the use of a 3-Stage Cleaning System, all of the dirt and dust on your floor is vacuumed up. This system is the same one you’ll find in the iRobot Roomba 690, and it works incredibly well.

Roomba 891 Robot Vacuum

Just as with the iRobot Roomba 690, as well, Dirt Detect sensors are used to tell the iRobot Roomba 891 where dirt is, and how it needs to go from one part of your floor, to another, to properly remove the dirt and dust that is on your floor.

What’s unique, though, is the fact that these sensors allow the iRobot Roomba 891 to adjust itself. When the iRobot Roomba 891 goes from one surface to another, these sensors allow the iRobot Roomba 891 to adjust the vacuuming process so that it can properly accommodate that new surface.

Summary of the Roomba 891 Features
– Power-Lifting Suction
– Premium 3-Stage Cleaning System
– Dual Multi-Surface Rubber Brushes

In terms of the suction power that the iRobot Roomba 891 offers, it offers three-times as much suction power as the iRobot Roomba 690. That’s a great deal of suction power, and you can easily use this robot vacuum to vacuum on hard and soft floors, of all sorts.

Other than that, the iRobot Roomba 891 is just like the Roomba 690. Very well-designed, easy-to-use, relatively affordable, and a great robot vacuum, overall!

What Does The iRobot Roomba 980 Offer?

The iRobot Roomba 980 is a BIG upgrade from the iRobot Roomba 891. With the iRobot Roomba 980, you have access to a variety of absolutely fantastic features that allow you to tailor the vacuuming experience to your specific needs, and to understand the overall extent of what it is that the robot vacuum is doing.

iRobot 980 Robot Vacuum

In terms of the basic cleaning process, it’s the same as the iRobot Roomba 690 and the iRobot Roomba 891. Using a remote control, or your smartphone, you have direct access to features such as scheduling and being able to adjust the suction, among various others. And, the cleaning process involves the 3-Stage Cleaning System, as well as Dirt Detect sensors.

Here’s the thing, these Dirt Detect sensors are significantly more advanced. Using the sensors, along with some new sensors that iRobot has added, the iRobot Roomba 980 can map out the entirety of the floor that the vacuum is on. That way, it always knows where it is, and where it needs to go. It becomes a seamless and quick vacuuming process, through the use of these new sensors.

That’s one of the biggest differences, between the iRobot Roomba 980 and the iRobot Roomba 891 and 690. These sensors make the navigation process faster, which then makes the vacuuming process quite a bit faster, as well.

The iRobot Roomba 690, as well as the iRobot Roomba 891, both have ninety-minutes of battery-life. But, the iRobot Roomba 980 gives you two-hours of battery-life. If you are vacuuming in a larger home, or in a space that is especially dirty, then these extra thirty-minutes make for a smoother and more productive vacuuming process. It can be very annoying when you have to recharge the robot vacuum before it’s finished vacuuming the floors in your home.

At the end of the day, though, the biggest difference between the iRobot Roomba 980 and the iRobot Roomba 690 and iRobot Roomba 891 has to do with performance. If you look at those two robot vacuums, and look at their performance, you’ll notice that they’re both pretty good. They can vacuum on many different surfaces, with a fair amount of ease. It’s not too challenging for them to remove dirt and dust from hard floors, as well as soft floors.

But, the iRobot Roomba 980 is the peak of robot vacuum performance. Using the iRobot Roomba 980, you can vacuum on any surface, with tremendous ease and efficiency. That’s because, in comparison to the iRobot Roomba 690, the iRobot Roomba 980 gives you ten-times more suction power! That is a lot of suction power, and with the help of the sensors and strong design quality, the iRobot Roomba 980 makes great use of that suction power!

If you want a robot vacuum that gives you exceptional performance, as well as all of the lovely design features and attributes that the iRobot Roomba 690 and the iRobot Roomba 891 give you, then the iRobot Roomba 980 is simply the best robot vacuum for you!
