As more and more things in the world are becoming automated, the one robot that I enjoy having in my home is my Roomba. Nothing is better than coming home to a house that’s nice and clean, especially if you are a very busy person. 

To help me find the best Roomba for my needs, I began looking in the 600 series, and I found two great models. So, I decided to create a head-to-head roundup reviewing the two products. In the battle of the Roomba 650 vs 690, which one comes out on top? 

In this guide, we will review both thoroughly to find out which one suits your needs more.

Things to Consider Before Buying a Roomba

When you are purchasing a new Roomba, there are going to be a few things that you will need to consider before you dive in and purchase the first option that you see. Some of the considerations should include:

  • The Types of Floors: Not all Roomba models are designed to clean all types of floors with the same efficiency. If you have thick carpet in your home, a robot vacuum may have issues navigating the fibers. Any Roomba will work well on medium to thin carpeting, and it should be able to clean bare floors.
  • The Size of Your Home: How large is your living space? Is it a single-level home or does it have multiple levels that will need to be vacuumed? Remember, these vacuums are designed to run on battery power. Having a home that is too large may mean that the batteries will not last long enough to clean the entire space. Roombas have limitations that you will have to think about. For example, if you have carpeted stairs, a robot vacuum will have a hard time cleaning the space.
  • Whether you have Pets: If you are a pet owner, you most likely know that the fur that ends up on the carpet easily gets tangled in the brushes of most vacuums. iRobot has developed an entire line of vacuums that work well for cleaning up pet hair. If you have a pet, especially one that sheds, then choose a model that works for your needs.
  • Type of Filtration System: If you have allergies, then a sound filtration system inside of the vacuum that you choose is going to be required. A lot of the Roomba models that you will find on the market actually have a HEPA filter, which is designed to eliminate more than 99% of the allergens.
  • Whether You Have a Smart Home: Some of these Roomba models are designed to be compatible with smart devices like Amazon’s Alexa or the Google Home series. Once you say the wake word, you will be able to send voice commands for the vacuum to follow. These functions sync with an application that you have on your mobile device, which provides you with some extra control. This is not available in all Roomba models, but if you like this type of functionality, make sure that it’s available on the device that you end up purchasing.

Features and Benefits: The Roomba 650

iRobot Roomba 650 Robot Vacuum

I really like this Roomba model because it’s a robot vacuum that doesn’t have a lot of the newer frills and technology. It takes vacuuming back to the basics, and since it is a Roomba, it requires a lot less work. It’s also a less expensive option if you don’t want to make a large investment right now. Some of the features of this option to consider include:

A Smart Navigation System

The Roomba 650 has a navigation system that will detect all of the surroundings and objects in your home. This will keep the unit from running into walls, falling down the stairs, and running over smaller objects. It does not have a memory system that will allow the device to remember what it learned the last time it vacuumed. However, it will be able to scan the area again with each new vacuum session. In addition, this unit is designed to come with a virtual barrier that you can use to set a perimeter for the vacuum to follow.

An Effective Cleaning System

This model has a three-stage cleaning system that is more effective than most. First, it agitates the carpet with brushes. Then, it uses its brushes to push all of the dirt to the same location. Finally, it uses the suction device to pick the dirt up off of the floor. Because of this effective system, the vacuum can clean any type of floor with ease.

An Easy to Use Filtration System

When you have allergies, it is always a good idea to have a vacuum that has a good filter. This will help you to clear the allergens out of the air easily. This vacuum is designed with a HEPA filter, which can clear away up to 99% of the allergens in the carpet and the air. It actually can remove anything that is larger than 10 microns, which includes dust mites, pet dander, and mold particles. When the filter is dirty, it can easily be cleaned with a little soap and water. The filter will need replacement at least once a year.

Cleaning Schedule Options

If you like to have your vacuum clean while you are away, this model allows you to set a schedule for it to clean. You will be able to tell the unit to clean at a specific time certain days of the week. So, if you would like to have the space cleaned three times a week, you can set it to vacuum on Mondays, Wednesdays, and Fridays. I love that the Roomba can clean the house while I am at work, but if you would like to clean it off of the schedule, that’s an option as well.

Battery Life

This is a unit that runs on a NiMH battery, which is an option that provides a good amount of battery life, but it’s not the best option on the market. This battery will provide about 90 minutes of run time for the vacuum. When the battery is low, the vacuum will return to the base so that it can charge up. The charging process should not take more than three hours.

Features and Benefits: The Roomba 690

The 690 serves as a great entry-level Roomba for those that don’t need the super-fine-tuned navigation systems of the more expensive models. This thing tackles debris and dirt well, and it also has a battery that performs well in most situations. Here are some of the essential features:

An AeroVac Cleaning System

It’s good to have backups, and the Roomba 690 has a three-stage cleaning system. This is the AeroVac cleaning system, and it is designed to pull as much dirt and debris up from surfaces as possible. The first two stages of AeroVac are designed to first sweep hardened debris from its surface and break it up into more manageable sizes. Once it’s broken up, the Roomba propels it into the center section of the 690 where the powerful vacuum sucks it into the dustbin.

For me, this is a really cool system that makes it so tougher stains and messes can be tackled directly. AeroVac also incorporates a filtration system that effectively removes pet dander from the air as well. I also love the fact that this proprietary system is relatively quiet. In most cases, you’ll be able to hear a standard conversation while the robot is doing its thing.

It Can Be Part of a Smart Home

This is one of my favorite features because I’m currently in the process of embracing home automation. To start, this is a Wi-Fi-enabled product. This means that, once you’ve connected it, it’ll have the ability to send reports to your smart device via iRobot’s app.

For me, this feels like a cool readout that gives me some basic stats about the job that the Roomba 690 is doing. Throughout the day, as it works, it’ll tell your favorite smart device about problem areas and battery levels. In addition, it’ll also give you a heads-up when it’s going back for a charge. This is more than novel since it gives you a good idea about any actual problem areas in your home.

This Wi-Fi connectivity isn’t limited to just app-compatibility. In fact, you can connect this product to your Alexa- or Google Home-enabled smart speaker. As a result, you can issue commands like “Hey Google, ask Roomba to clean” or “Alexa, ask Roomba to return to the dock.” This makes it so that you can activate the little robot while you’re doing other things around the house. You can even create routines through your virtual assistant.

A Good Level of Maneuverability

Some of us have areas of our homes that are more cluttered than others. When this is the case, some robots will run into problems traversing the room. Fortunately, despite its randomized cleaning pattern, the Roomba 690 performs well in tighter areas. It can even get under dinner tables and clean the spaces between the legs of the chairs.

It Tackles Corners Well

In my experience, the walls are typically a casualty of the advent of the robot vacuum. Many products blow dust and debris onto the baseboards until you end up with dirty walls. This device avoids this by using reasonably stiff brushes to clean along the base of your walls. These are positioned at a 27-degree angle, so they do a pretty good job of ensuring that there’s no dirty wall base. It’s important to note that these can cause scratching on some materials, but it’s excellent on hardwoods and other tougher baseboards.

Problem Area Intelligence

Do you have high-traffic areas in your home that seem to be dirt magnets? I think we all do, and this is the reasoning behind the Dirt Detect technology from iRobot. The 690 uses this tech to determine if an area of your carpet is dirtier than others. If this is the case, the Roomba 690 will pay particular attention to that spot. Additionally, this is one of the alerts that it’ll beam to your favorite device. This means that if you receive a lot of Dirt Detect events, then you know that your 690 may be working a little harder.

Roomba 650 vs 690: Social Proof

When I was looking into these two different iRobot Roomba models, I decided to scour the internet to see what others had to say about them. Most of the Roomba users who use these two models love how well they both clean the floor. Most Roomba 650 users love the simplicity of the vacuum. Users of the 690 tend to enjoy how easy it is to manage. They also like how the vacuum has Smart functionality that gives choices for controlling the Roomba via the internet. One of the major complaints about both of the models is that the dust bins are a bit too small. This means that it may need a good cleaning before you are finished vacuuming in a larger home.

Roomba 650 vs 690: Final Thoughts

As you know, I’m here to determine the winner in the battle of the Roomba 650 vs 690, and for features, the 690 seems to pull ahead. While both have good battery life, a three-stage system of cleaning, and pretty good navigation, the 690 just wins out in other places. Features like the smart connectivity add convenience to this budget-priced Roomba. Also, I think the dustbin system on the 690 is just better than the one that’s available on the 650. While I love the spot cleaning function on the 650, being able to voice control the Roomba 690 feels like a better feature.
