I, for one, am a big fan of robots. I think that automation is great, especially if it helps save me time. I have reinforced this logic in my day-to-day life by getting an iRobot Roomba to clean my floors. In this guide, I am going to compare two options that are quite popular with robot vacuum users. In this Roomba 650 vs 770 head-to-head, let’s see which one comes out as the winner.

Things to Consider Before Buying a Roomba

When you are considering purchasing a Roomba, there are a lot of different options to think about. The first consideration to make should be the size of the space that you will be cleaning. Some vacuums have smaller dustbins, so you will have to empty them more at a more frequent rate. I find that most models will be able to clean an average-sized house without emptying the bin.

Also, some Roombas will pick up pet hair with ease. If you have a cat or a dog, then you may need to consider one of these options. Instead of a brush, plastic agitators are present so that the hair doesn’t get tangled inside. If you have a pet, you are going to want a Roomba that has a lot of suction power so that it gets the dust and dander out of the carpet.

For individuals who have allergies, a HEPA filter is vital if you would like to remove the allergens from the air. This is a type of filter that can help to remove more than 99% of the allergens that are present. This may not be all of the allergens, but it is much more effective than some of the other filters that are on the market.

Also, since these are not the newest models on the market, remember that they may be missing some of the latest tech. This can mean that you will need to turn on the vacuum by hand instead of doing it from a remote position. One of the new techs that you will most likely want is a battery that has a useful lifespan. Sometimes, these will only last for a little bit of time before they need a charge. A lithium-ion battery is a good option that many Roombas use today.

When it comes to the Roomba 650, there are a lot of good reasons to choose this product. It can adjust when it moves from room to room. This means that it can clean every type of floor with ease. I like the fact that it automatically docks when the vacuum needs a recharge. Some of the pros and cons of this product include:

Pros

  • The recharge period is minimal.
  • It picks up pet fur with ease.
  • It’s easy to set up the vacuum.
  • The vacuum has a self-docking mode when the battery is low.

Cons

  • The size of the machine makes it easy for it to get stuck under furniture.
  • The dust bin is small.
  • The vacuum is a bit loud.

The Roomba 770 is another option that has a three-stage cleaning system that is quite effective. It uses iAdapt navigation to move around your home without getting stuck. This system is great for determining where furniture is, and it also has a mode that helps to detect where the carpet is the dirtiest. The pros and cons of this product include:

Pros

  • This vacuum picks up pet hair with ease.
  • It cleans under the furniture without getting stuck.
  • It does a great job cleaning on carpeted and bare floors.

Features and Benefits: The Roomba 650

iRobot Roomba 650 Robot Vacuum

The Roomba 650 is an older option, but it’s still a trendy choice amongst iRobot users. This model is one that has a lot of features but not the most up-to-date options. If you are looking for something that doesn’t have a lot of flair to it, then this is an ideal option. Some of its more standout features to consider include:

 A Unique Design

This model is black like most Roomba machines. The main difference that makes it stand out is the green button in the center that says clean. This is the button that you use to turn the device on. However, the addition of color to the button makes it look unique and even more attractive. The dimensions of the vacuum are small at 13.4 by 3.6 by 13.4 inches. These dimensions make it possible to fit under most furniture.

Overall Performance

This unit can clean floors with ease using the three-stage cleaning system, but since it covers the floor using random patterning, it can take a while. It’s designed with the ability to auto-adjust when it goes from room to room. The vacuum has a dirt detection mode that can help the vacuum find a dirty spot and focus on getting it clean. With this model, you can set up virtual walls that can set a perimeter for the vacuum to follow. This makes cleaning a space more convenient when you cannot babysit the vacuum.

Effective Cleaning Ability

The vacuum will clean any type of floor with ease. It has Smart cleaning option that you can use as well. This unit does not have multi-room navigation, so it’ll limit your cleaning to a smaller area. When the dustbin is full, there isn’t an indicator to let you know that it’s time to empty the device. When you are ready for the unit to vacuum, there is a scheduling option available. This makes it possible for the unit to clean the space at the same time every day.

Type of Filtration System

The Roomba 650 doesn’t have a HEPA filter. Instead, it has an AeroVac filter, which has the power to block out the majority of allergens in the air. In fact, when thinking about this filter, it’s best designed to handle dust, debris, and pet dander. These filters are easy to replace and easy to clean. It can be done with a damp cloth or towel. While it won’t quite keep out smaller particles like a true HEPA, it’s still the right solution for those with allergies.

Battery Life and Self Charging

When it comes to the battery, the Roomba 650 has a nickel-cadmium battery that isn’t quite as good as lithium-ion battery types. These batteries last between 18 and 36 months before they will need a replacement. Purchasing them from iRobot is also easy. On a charge, you can expect the 650 to last about an hour to an hour and a half before it will need to return to the dock. While on the dock, the Roomba will need about two to three hours to fill up.

When the job completes, the robot has a self-docking function that will have it automatically return for charging. This adds a lot of autonomy to the product, so you’ll be able to interact with the Roomba less. Sometimes, it may have problems finding the dock, but this is rare.

Additional Features

The 650 has cliff detection, which is very useful for those with houses with stairs or other sudden drops. When the Roomba detects an edge, it’ll treat it as a wall and turn around and start off in another direction. This prevents the device from taking extra damage. Also, at a height of less than inches, the Roomba can get under obstacles, which helps provide a much more complete clean. Finally, the robot comes with a virtual wall that helps it avoid areas that you don’t want it to clean.

Features and Benefits: The Roomba 770

The Roomba 770 is an option that is also very popular. It is not a new model by any means, but it has a lot of features that made Roomba so popular to begin with. Though it may be missing some of the newest advances, it has many of the most loved options. The top features of this model include:

 A Unique Design

The Roomba 770 has a very similar design, but it does have a few improvements. It’s black in color, and the clean button glows green. A few buttons were added to the top of the vacuum to make it easier to control. The dimensions of this vacuum are 13.9 by 3.4 by 13.9 inches. This makes it even easier for it to clean under furniture without getting stuck.

Overall Performance

In general, the Roomba 770 cleans pretty well. It does a thorough job on carpet and other types of floors. This unit has a much more organized method to clean, so it does not randomly move across the floor. The detection system of the Roomba 770 is superb. It can detect most furniture and items that are on the floor before it bumps into the item. This means that the vacuum can avoid larger items with a high degree of reliability.

It will self-adjust when moving from room-to-room. It also has the iAdapt navigation system to help it move around the space. It’s even designed to adjust the sensors of the vacuum when it moves from room to room. The Dirt Detect Series II is perfect for focusing on cleaning a spot that requires it more than others.

Effective Cleaning Ability

The Roomba 770 has a very unique cleaning experience that I personally think is great. It has an intelligent AI that allows the unit to clean up with over 90% efficiency. The navigation system is ideal for a larger home. In fact, it has a multi-room navigation system that will allow it to learn multiple spaces at the same time. It also has a Smart schedule option that can schedule the unit to clean your home whenever you want.

Type of Filtration System

This is a vacuum that has a dual HEPA filtration system that is great for cleaning away allergens. It does an excellent job clearing dust particles, pet dander, and pollen so that you will be able to breathe without an issue in your home. In fact, this filtration system can clear more than 99% of the allergens in the air. This type of filter is effective with particles that are as small as 0.3 microns. These filters are simple to clean, and they can be removed and replaced with ease.

Battery Life and Self Charging

The Roomba 770 uses nickel-metal hydride battery, which is called NiMH by most. Overall, you can expect the battery to last about an hour and a half, which is similar to the 650. When the device is starting to get low, the light on the Roomba 770 will turn yellow. Green is the default color that lets you know that the battery is full or near-full. When the battery is low, the device will also return to its power station to recharge.

Additional Features

This is one of the few Roombas that you can control using a remote control. This gives you direct control of the unit and can be a convenient way to clean. Also, this is lower than the Roomba 650 by a slight margin, which means that you can get under more objects. When the device’s bin is becoming full, the full bin indicator will go off.
