iRobot Roomba 690 vs 671 vs. 675: Robot Vacuum Comparison

iRobot is the creator of the Roomba. Right now, the Roomba models are the most popular robotic vacuum cleaners on the market. For a good reason. The Roomba brand was one of the first to showcase these nifty devices. iRobot has consistently shown itself to be one of the best, if not the best robot vacuum cleaner brand on the market.

Today, there are many different models of the Roomba, and it can be a little challenging to figure out which Roomba is the best one for you. This article hopes to remedy that problem by looking at, and comparing, three different Roomba robot vacuum models. The Roomba 671, the 675, and the 690.

The Roomba 671

The iRobot Roomba 671 is a small, light device. It weighs only five pounds, and it is very “slim”. Meaning that if you have spaces underneath your couch, for example, it can easily reach and suck up all of the dust and dirt that tends to nest itself underneath furniture.

Since this device has Wi-Fi connectivity, you can use either your smartphone/tablet, by installing the official iRobot HOME App, or by using Amazon Alexa or Google Assistant, if you have it. Using either of those features, you can turn on the robot vacuum cleaner, and you can also create a custom schedule. For example, you can have the vacuum clean for twenty-minutes on Monday, at three o’clock in the afternoon. And then, on Tuesday, it’ll clean for thirty-minutes, at noon. Even if you don’t have a specific schedule set up, you can still turn on the vacuum at any time, wherever you are, if you have Wi-Fi.

Using a three-stage cleaning system – that iRobot has patented – the device is able to suck up big pieces of dirt and debris, as well as smaller particles, such as dust and talcum powder. This is aided by the use of sensors, enabling the vacuum to adjust the different cleaning systems and settings, while it’s cleaning, to best suit the type of surface it is on, and the level of dirt on the surface.

In total, it can run for up to ninety-minutes, without needing to be charged. When it does need to be charged, it goes right back to its charging dock.

The Roomba 675

In many ways, the iRobot Roomba 675 is almost the exact same robot vacuum as the Roomba 671. However, there are a few key differences that must be mentioned.

First and foremost, the Roomba 675 has these “Dirt Detect” sensors that enable the device to detect areas where there is a large concentration of dirt and grime, and this, in turn, allows the device to work harder at removing this dirt and grime.

Now, the Roomba 671 is also equipped with sensors designed to detect dirt and grime, but it doesn’t have the same functionality as the Roomba 675, in this department. It doesn’t always detect the areas where dirt is most concentrated, and so it doesn’t always get the floor as clean as it should be.

Other than that, however, the two devices are almost completely identical. They are both very good, very well-made devices that have the same capabilities. However, the Roomba 675 may be especially useful to you, if you have a larger family, which means more foot traffic, and that, in turn, means more dirt. The 675 will do a great job detecting it and cleaning it up.

The Roomba 690

Just like the two models before it, the Roomba 690 has the same features, and is an exceptional vacuum. There is only one extra feature in the Roomba 690, however, and that is the inclusion of a “Virtual Wall Barrier”.

A Virtual Wall Barrier is a physical sensor that you place around a specific point in a room, and when the vacuum is cleaning, it’ll detect this sensor, and know to stay within the parameters of that sensor. Using this Virtual Wall Barrier enables you to clean only one particular space, rather than having the vacuum start to clean the entire house. Along with that, you can choose to run the vacuum for longer in that particular space, meaning that the vacuum will have more time to clean everything within that space thoroughly.

Ultimately, both the Roomba 671 and Roomba 675 are nearly identical, but the Roomba 675 is more capable when it comes to detecting dirt and, of course, getting rid of it.

The Roomba 690 has that capability, as well as allowing you to have more direct control over where the vacuum goes and what, specifically, it will clean.
