If you have a busy house like mine, you know how difficult it is to keep your floors clean. Kids and pets going in and out bring in more dirt and dust every day. This situation has inspired me to look at tools that can help win this battle for a clean floor. Right now, I am looking at robotic vacuums. Keep reading for my Roomba 805 review.

What to Think About Before Buying a Robot Vacuum

Robotic vacuums seem like the perfect solution to keep your home clean. With the press of a button, or a voice command in more advanced models, you can set your Roomba to work, vacuuming throughout your house. If you are someone who appreciates consistent cleaning, you might want to consider putting a Roomba to work on your floors.

However, because a Roomba is a serious cleaning investment, there are some things to consider about whether or not it is the best choice for your home. An important thing to remember is that Roombas do not handle clutter. iRobot designed the Roombas to avoid obstacles, whether it is a piece of furniture or blocks your child has left scattered on the floor. Roombas work best when there are as few obstacles as possible. This might inspire you to clear the clutter from the floors, or it may just frustrate you.

Another consideration is how much you like to work with technology. Some people simply do not enjoy the idea of giving up control to a robot. Especially with older Roomba models like the 805, some owners express frustration with the random navigation pattern where some areas are cleaned more than once and others are missed. If you are going to spend your time worrying about the space the Roomba has not yet cleaned, you might want to stick with a nice, bagless vacuum and control the cleanliness yourself.

Roomba 805 Review: Getting to Know the 805

iRobot Roomba 805 Cleaning Vacuum Robot with Dual Virtual Wall Barriers and Bonus Filter

The Roomba 805 can vacuum dirt and dust from all your floor surfaces. It has a stronger AeroForce cleaning system which provides more suction than the 600 and 700 Roomba lines. While it does not have Wi-fi connectivity, you can schedule cleaning sessions using buttons similar to a standard digital alarm clock. One of the unique things about the 805 compared to other Roombas in the 800 line is its size. It is about six inches wider than similar models, so it can cover a large area faster. This works best if the Roomba is working in a large, open space. The Roomba 805 comes with two Virtual Walls and an extra high-efficiency filter.


  • Wider size for faster cleaning
  • Easy scheduling
  • Tangle-free rubber rollers


  • Extra height limits its travels
  • No Wi-fi connection
  • Can run out of charge before reaching its charging dock

Essential Features of the Roomba 805

iRobot Roomba 805 Cleaning Vacuum Robot with Dual Virtual Wall Barriers and Bonus Filter

The Roomba 805 is a powerful piece of cleaning technology. Its many features allow it to provide a consistent and convenient cleaning service for your home.

iAdapt Navigation

The iAdapt Navigation system addresses one of the issues of earlier models, scuffed furniture. This navigation system does not map your room but relies on external sensors to keep the unit from bumping into obstacles. When the 805 approaches an obstacle, it will slow down and touch it gently, protecting both the unit and the object. The cleaning pattern of these units is a bit random, so it is always fun to guess where it will go next. You can also guide your Roomba with the included Virtual Walls. These devices trigger the boundary sensors on your Roomba. This can confine the unit to a single room or help it avoid areas like pet bowls where it could cause a spill.

Like all Roombas, the 805 has Cliff Detection Sensors that prevent it from falling off of ledges. These are calibrated so that the unit can go over transition strips or different types of floor surfaces without an issue. When it approaches a stair, it will clean to the edge and then change directions.

AeroForce Cleaning System

The AeroForce Cleaning System is an upgrade from the AeroVac system found in the 600 and 700 Roomba lines. The Aeroforce System is supposed to have five times the amount of suction and cleaning power than previous systems. This is important to me because it takes more suction to fully clean a carpet than a hardwood or vinyl floor. With more suction, the unit can pull deeper dirt and dust as well as surface dirt.

Tangle-free Extractors

In previous models, pet owners complained because the units would get stuck when pet hair tangled in the cleaning brushes. The 800 line, including the 805, uses tangle-free rubber extractors. The tread pattern helps the robot lift dirt and suck it away. My dogs shed a lot of hair, so it is helpful to have a unit that can handle the problem.

Dirt Detect Sensors

The 805 has special dirt detection sensors under the unit. When these sensors detect an area that is particularly messy, they signal the Roomba to change its pattern. In this model, the unit turns in a slow circle until the area is clean. This is perfect for spills around the children’s craft table or for cleaning up messes that have been tracked in.

Control at the Push of a Button

Unlike later models, the 805 does not have a Wi-fi connection. It cannot be controlled with the iRobot app or voice commands. All controls are located on top of the unit. However, the button-controlled functions have expanded from earlier units to include the ability to create a cleaning schedule.


The “Clean” button is the all-purpose button that sends the Roomba out to clean. If you have inputted a schedule, you press this button to start the timer. If there are no scheduled cleanings, pressing the clean button will send your Roomba 805 on its merry, vacuuming way.


Sometimes you need your Roomba to get out of the way. Normally, when it runs low on charge, it automatically makes its way back to the charging dock. By pressing the “Dock” button, you will interrupt the cleaning cycle and send the Roomba back to its base.


The scheduling buttons on top of the Roomba let you set a daily schedule for your unit. This allows you to set the unit to work while you and your family are out for the day. You can also set it to make multiple cleaning runs if you are trying to keep up with dog hair. A clean house at the end of a long day is a real gift.

Lithium-ion Battery for Extended Operation

The Lithium-ion battery gives your Roomba about 60 minutes of operating time. It takes about three hours to get back to a full charge. Because of the larger size of the 805, there have been some complaints about it failing to make it back to its charger at the end of a cycle. In order to prevent this issue, it is important that you locate the docking station in an appropriate place.

Positive Reviews for the Roomba 805

I have been looking at customer reviews for the Roomba 805 and have found that, generally, people enjoy having this unit around. Pet owners are especially thrilled with a vacuum that makes their lives a little cleaner. A number of people also appreciate the ability to schedule the cleaning while they are away without having to use another phone app.
