I love it when my house is clean. There is something wonderful about spotless floors and dust-free surfaces. The problem is, I do not like cleaning. My life is already busy enough without having to deal with pet hair and other messes. I am always on the lookout for a device that can save me some time. Recently, I have started looking at the different kinds of robotic vacuums that promise to give me some relief from my chores. Keep reading to learn about my comparison of the Roomba 761 vs 770.

Is a Roomba Robotic Vacuum the Right Solution for your Home?

In most situations, a robotic vacuum will be a big help in dealing with dirt and dust around your home. iRobot designs these devices to work with any kind of floor surface, from carpet to vinyl. They slowly figure out their way around your home, vacuuming all the way. Most homeowners are shocked when they first run the device. They wonder how their little robot can pick up so much dust every day. Because these devices are designed to go under furniture, they clean in places that people rarely touch with a regular vacuum.

However, a robotic vacuum is not the solution for every home. It is important that you have realistic expectations when you consider one of these machines. They can do a great job, but they are not perfect. Most people who own Roombas still find that they have to do some spot vacuuming. The random navigation pattern can miss places here and there. In addition, if you have deep pile carpeting, you may need a stronger vacuum to clean deep into the fibers. If you want a comprehensive cleaning solution without doing any work, you may want to have a professional cleaning service handle your home.

Another important consideration is the number of places in your home where you would not want a Roomba to go. Using a Virtual Wall device, you can block the robot from entering sensitive areas. You may want it to avoid your dog’s water bowl and the mess it could make. You may want to keep the robot away from a top-heavy pedestal that showcases an expensive vase. If you are going to be blocking the unit from many areas, it is probably not a great investment. Instead, stick with your regular vacuum, and make sure you have the attachments to clean things carefully.

An Introduction to the Roomba 761

iRobot Roomba 761 Vacuum Cleaning Robot

The Roomba 761 is the earliest model in the 700-series of iRobot vacuums. This new generation has some slight advantages over the previous 600-series. The 761 uses the traditional iAdapt 1.0 navigation system, but its behavior has been modified to make it gentler on furniture. It also has a stronger vacuum system than its predecessors. The Roomba 761 has programmable scheduling buttons that allow you to run the unit while you are out of the house. In the 761 package, you will find the robot, a charging dock, two Virtual Wall devices, a remote control and an extra set of dual AeroVac filters.

Pros

  • Simple scheduling buttons
  • Larger dirt bin than previous models
  • Removes dust from under furniture

Cons

  • Noisy operation
  • Erratic vacuuming pattern
  • Brushes get tangled with pet hair

Get to Know the Roomba 770

iRobot Roomba 770 Robotic Vacuum Cleaner

One of the challenges in comparing two models of Roomba vacuums in the same generation is that they often share many of the same features. The Roomba 770 shares its navigation system, cleaning system and scheduling capabilities with the 761. It has upgraded Dirt Detect sensors that help the unit handle dirtier areas. It also has a different style, going back to the traditional black color-scheme as opposed to the silver and grey of the 761. The 770 package includes the robot, charging station, remote control, extra filters and two Virtual Wall devices.

Pros

  • Gives floors a consistent clean
  • Full dirt bin indicator light
  • 60-minutes of cleaning per charge

Cons

  • Can get lost and lose charge
  • Struggles with deep pile carpet
  • Filters need to be changed too frequently

The Essential Features of the Roomba 761

iRobot Roomba 761 Vacuum Cleaning Robot

The Roomba 761 is equipped with technological advances that make it a high-powered cleaning machine. A great deal of research and innovation goes into giving these droids the ability to do their programmed task, exploring your home and picking up dirt and dust along the way.

AeroVac 2 Cleaning System

The 700-series cleans your home with a three-stage cleaning system. As the robot travels, a spinning side brush sweeps dirt into the path of two other brushes beneath the unit. These two brushes loosen and lift dirt, directing it toward the vacuum opening.

The second cleaning step is the AeroVac vacuum. This vacuum is a bit stronger than the original AeroVac found in the 600-series. The added strength gives it more power to handle carpeted surfaces. It also does a better job at picking up pet hair.

Once the mess has been pulled into the unit’s dirt bin, the final step is the AeroVac 2 dual filters. While these are not HEPA filters, they are strong enough to keep most dirt, dust and dander particles out of your home. The move to dual filters allows for more storage space in the dirt bin, letting your Roomba clean with fewer interruptions. With regular use, you will need to change the filters every few months. Extra filters can be purchased online.

Sensor-driven Navigation System

The Roomba 700-series uses the iAdapt 1.0 navigation system. As it sets out on a cleaning mission, exterior sensors detect obstacles in the Roomba’s way. iRobot modified the behavior of the 700-series to address complaints of scratched furniture in previous models. When the 761 senses an obstacle, it slows down and touches it gently. If the obstacle gives way, like an upholstery flap on a couch, the vacuum will push through. Otherwise, it will mark that location on its mental map and change direction.

As the robot travels around your home, it slowly learns the shape of the room. This means that it will become more efficient as it progresses. However, these machines do not remember the map from one cleaning cycle to the next. They start each session with a clean slate.

The 761 comes with two Virtual Wall devices. By using these, you can steer it away from breakables or other sensitive areas. You can also use these devices to corral your droid, keeping the robot in a single area until it has been fully cleaned.

Programmable Scheduling Buttons

All of the models in the 700-series are equipped with onboard scheduling buttons. These controls offer you the convenience of setting a cleaning schedule. You can set a time for a daily vacuuming session, or you can create a weekly schedule, varying the time to suit your family’s needs. For the highest efficiency, make sure to pick up as much clutter from the floor as you can before the cleaning cycle begins.

Remote Control

The 700-series standard package includes a remote control. Using this device, you can guide your robot to a specific area of your home. If you feel like the unit has been cleaning in one part of the room for too long, you can force it to go to another. This is also a helpful device for guiding the Roomba to an area that needs extra attention. If you use the remote to send it to a larger mess, the Dirt Detect sensors will instruct the robot to spend more time vacuuming that area.

Replaceable Nickel-metal Hydride Battery

The Roomba 761 is powered with a rechargeable NiMH battery. This battery gives about 60 minutes of cleaning with each charge. When the robot’s battery level falls below 20 percent, it stops and seeks out its charging dock. Once it has located the dock, the unit takes four to five hours to reach a complete charge. It is very important to place your dock in an area that is free of furniture and other items. If the Roomba senses too many obstacles, it can get confused and have a difficult time locating its home. Eventually, it will run out of charge, and you will have to carry the vacuum to its home.

Upgraded Features of the Roomba 770

Almost all of the features of the Roomba 770 are the same as the 761. iRobot vacuums in the same series often have only minor differences that set them apart. In the 770, the biggest improvement is an upgrade to the Dirt Detect sensors.

Upgraded Dirt Detect Sensors

Underneath a 700-series model is a set of Dirt Detect sensors. The 761 has the first generation of these devices. The 770 has the upgraded, second generation of Dirt Detect technology. One of the complaints about older models was that the unit had trouble detecting fine messes like spilled flour. In the second generation, a mix of acoustic and visual sensors improves the detecting ability. When the Roomba 770 detects a more serious mess, it interrupts its normal cleaning cycle and spends more time on that section. Once it gets the message that the area is clean, the unit resumes its normal vacuuming program.

Traditional Roomba Design

As opposed to the retro silver and grey design of the 761, the 770 has returned to the traditional black color scheme. The appliances in my kitchen have a black finish, so the Roomba 770 fits in well with them.

Consumer Reviews of the Roomba 761

The measure of any device is how well it performs in the real world. I have been pouring over reviews of these units, and here is what I found. People who own the Roomba 761 have found it to be helpful in their homes. They love the ability to program the machine. In most cases, they only have to clean out the dirt bin when they get home from work. Several commented on the improved cleanliness they see in their homes with a daily vacuuming run.

Positive Feelings about the Roomba 770

The Roomba 770 gets similar positive reviews. This should not be a surprise since the 761 and 770 are almost the same unit. Consumers commented on the 770’s reliability and simple programming. They found that the battery life was long enough to clean the floors of the main living areas of their homes.

The Roomba 761 vs 770: My Choice

In this comparison, it is difficult to choose one unit over the other. Except for the Dirt Detect upgrade, these two robots are essentially the same. They also come with the same amount of equipment in their standard packages. In this case, the decision really comes down to style and price. If you have a strong preference between the black 770 and the silver 761, that may the deciding factor. Because the 761 is a little older, you may be able to find it at a lower price which may affect your decision. Whatever decision you make, I think you will be pleased with either of these vacuuming helpers.
