If you are in a hurry and just want to find out what the winner is, then we recommend the Roomba 650.
With my busy schedule, keeping dust off my floors sometimes gets pushed down a few places on my to-do list. Yet, if I don’t do it, no one else will. A robotic vacuum might be able to handle this job, freeing up my time while giving my home a consistent level of cleanliness. There are many of these cleaning droids on the market. In this article, I will do a comparison of the Roomba 665 vs 650.
Things to Consider Before Buying a Robotic Vacuum
The market for robotic vacuums continues to grow because of their convenience. The right robot can be a big help in keeping your home clean. These robots use sensors to navigate your home, avoiding stairs, furniture, and other obstacles while picking up dust, dirt and pet hair. For those who like to count on clean floors, a robotic vacuum could be the answer to your problems.
However, as with any technology, a robotic vacuum in the wrong situation could get frustrating. Earlier models of the Roomba like the 665 and 650 are best in a smaller house with a simple floor plan. They do not have the technology to remember where they have been. When they go back to the charging dock, they start from scratch at the next cleaning cycle. If you have a larger floor plan, you may want to look for a unit with a longer-lasting battery and better navigation technology.
Another important consideration is the amount of clutter you allow in your home. If you have kids, you have clutter, whether it is toys or piles of schoolwork scattered on the floor. Robotic vacuums are designed to avoid objects in order to prevent damage. This means that cluttered areas will not get a complete vacuuming. It would get very frustrating to invest in this technology and never get to put it into full use. For a full clean that also handles clutter, you might want to bring in a cleaning service once a month.
Finally, there is the matter of control. Most basic robotic vacuums use a random navigation pattern based on interacting with objects in the room. When the unit approaches an object, it will change direction to avoid a collision. Some customers find that this can lead to inconsistent cleaning, where one area gets several passes while others are not touched. If you want full control of your vacuuming, you will be happier if you invest your money in a bagless, upright vacuum.
Presenting the Roomba 665
The Roomba 665 is a powerful cleaning tool for your dirt-fighting arsenal. It has the standard features of Roombas in the 600-series like the AeroVac cleaning system and Dirt Detect Sensors. In addition, it also has scheduling buttons that allow you to put the unit on a daily or weekly cleaning plan. In the standard package, in addition to the 665, you receive a Virtual Wall device, a charging dock, and an extra AeroVac filter. The 665 also has unique styling with a silver faceplate and yellow trim, perfect for homes with a lighter color scheme.
- Multi-surface cleaning
- Easy scheduling
- Automatic charging
- Random navigation pattern
- Sometimes loses charge before reaching docking station
- Dirt bin requires frequent cleaning
Presenting the Roomba 650
The Roomba 650 is another robot that can get the job done. Like the 665, it features the AeroVac cleaning system and sensor-driven navigation. It also features the ability to schedule a cleaning cycle while you and your family are out of the house. The 650 comes with the same equipment as the 665. It has the classic Roomba design, a black faceplate and silver trim. The primary differences between the 665 and 650 affect cleaning capacity. The 650 has a longer battery life. It also has a dirt bin that is more than 50 percent the size of the 665. All of this means a longer cleaning cycle with fewer interruptions for a full bin.
- Increased running time
- Large-capacity dirt bin
- Daily or weekly scheduling
- Navigation issues
- Struggles to deal with deep pile carpet
- Brushes can get tangled with pet hair

Essential Features of the Roomba 665
One of the challenges of writing this review is that these units use much of the same technology. iRobot makes incremental changes with each new release, improving a few features each time. This is true for comparing the Roomba 665 vs 650. The two units share most of the same features, so this discussion of the 665 can be applied to the 650. However, it is important to note that those shared features can make both of these units helpful cleaning tools for your home.
AeroVac Cleaning System
The AeroVac Cleaning system is the standard system of the 600-series of Roomba products. The cleaning system begins with two bristled brushes that lift and extract dirt and dust from your floor. Then, a powerful vacuum system sends the mess to the sealed dirt bin. While iRobot designed this system for all floor surfaces, consumers say that it works best on non-carpeted surfaces or low-pile carpeting.
The AeroVac filter is an important component that keeps dust and pollen out of your house. While it is not as powerful as the HEPA-filters in later units, the AeroVac filter does a good job of keeping many particles out of the house. Less dust on the floor means less dust that can be kicked up onto other surfaces or into the air supply. These filters are not reusable. An extra one is included in the package, and more can be ordered online.
The Roomba sensors are what help Roomba vacuum cleaners perform their magic. Even in the basic models, the information that comes from the infrared sensors helps the robot’s brain make 60 decisions every second. Although the pattern can seem random, Roombas have a reputation for providing all-around cleaning.
In the 600-series, the primary decision-making sensor deals with walls and other obstacles. When the Roomba senses an obstacle, it approaches it slowly and pushes on it lightly. If it can pass, it will continue through. This feature lets it go under fabric barriers like a long tablecloth. If the object is solid, the Roomba will change directions. In this series of Roombas, the robot makes a temporary map of the places where it changed direction, but that map disappears when the cleaning cycle ends.
One of the most important Roomba innovations is the cliff detection sensor. It is one thing to bump into a wall, but it is another to go careening down the stairs. You can find this sensor on the bottom of the Roomba. When it senses a drop, the unit quickly changes directions. This sensor is calibrated so that the Roomba can make it over reasonable drops like a transition strip or moving from a carpeted area to hardwood.
Dirt Detect sensors make the Roomba more effective. You probably have areas of your home that are prone to messes. Family members track in dirt by the doorway. An infant spills cereal from a highchair. When the Roomba passes the area, it recognizes that there is a larger mess. It then spends more time vacuuming the space until it is clean.
Each 600-series Roomba comes with a Virtual Wall device. You can easily order more online if they are helpful. There are some parts of your home that you might want your Roomba to avoid. This device sends out a signal that triggers the obstacle sensors and keeps the robot away. Some people also use these devices to limit the Roomba’s cleaning area. If I don’t want to deal with clutter, I can have my family move their things into a spare room. Using the Virtual Wall, I can tell my Roomba to keep out of the cluttered room.
Both the 665 and the 650 operate using the same suite of buttons found on top of the unit. Neither unit has a Wi-fi connection that allows for more advanced control through the iRobot smartphone app or voice control.
The big button at the center of Roomba is the one that tells it to go. This button turns the Roomba on to start a basic cleaning cycle.
The 600-series Roombas are equipped with a handle for easy lifting. If there is a mess you want to be handled right away, you can pick up your Roomba and place it in the center of the mess. When you press the Spot button, the Roomba will travel in a spiral pattern until it vacuums a circle about 3-feet in diameter.
Every Roomba needs a place to call home. When the Roomba’s charge falls below 20 percent, it will automatically seek its charging dock. However, if you need your Roomba to get out of the way, this button will interrupt the current cleaning cycle and send it searching for its home.
An important addition to these 600-series models is the ability to schedule a cleaning cycle. Earlier units could only be started manually. By using the schedule buttons, you can have your Roomba start a cycle at any time of day or program a weekly schedule. This is convenient because it means you can send the Roomba cleaning while your house is empty.
Essential Features of the Roomba 650
As mentioned above, the Roomba 650 shares its essential features with the 665. However, there are two upgrades that make a big difference.
Lithium-ion Rechargeable Battery
Both Roomba units come with a lithium-ion rechargeable battery. However, the 650 comes with a longer-lasting charge capacity. This little guy can work for 75 minutes on a single charge while the 665 averages 60 minutes. This amount can be the difference between a partial and full cleaning job. Both units take about 3-hours to fully recharge their batteries.
Increased Dirt Bin Capacity
While a larger dirt bin may not seem like a big deal, it makes a big difference when it comes to convenience. The 650 has almost 34 ounces of storage capacity while the 665 only has 20 ounces. This means less cleaning out the dirt bin for you and a longer cleaning time for your Roomba. The Roomba will stop its cycle when the bin is full which can be inconvenient if you have scheduled it to run while you are out of the house.
The Reviews Are In
I have been checking out lots of consumer reviews, and it is clear that people enjoy both the Roomba 665 and the 650. This makes sense because the units are similar in so many ways.
Customers praise the Roomba 665 for its ability to provide a reliably clean home. They especially appreciate the scheduling feature. The unit cleans during the day, and they only have to clean out the dirt bin at night. Some customers also appreciate the silver and yellow design that sets this unit apart from other models.
In much the same way, customers rave about the Roomba 650. They like that the extra dirt bin space and enhanced battery life help their Roomba complete its mission every time. For a simple floor plan, the Roomba 650 seems to be a reliable way to keep things clean.
My Final Thoughts on Comparing the Roomba 665 vs 650
It is hard to pick a clear winner in this competition. In the long run, I put more value on practical features than style. While the silver and yellow design of the Roomba 665 may make it unique, I am going to choose the Roomba 650 for its longer battery life and dirt storage capacity. For my money and convenience, I want a robotic vacuum that can clean my home with the least amount of fuss on my part.
