iRobot Roomba 805 Robot Vacuum Review: Is This The Best Robovac Yet?

Last Updated on June 1, 2022 by Emma W. Thomas

With the introduction of robovacs, gone are the days where you have to manually use a vacuum cleaner just to clean your house. Nowadays, robot vacuums can be programmed based on your preferences, and you can just leave the vacuuming task to them as you do your other chores.

Of the many robovacs on the market, the Roomba 800 series has stood out from the rest due to the features that each of the products included in the series has to offer. One particular model, the Roomba 805, managed to capture our attention due to its budget-friendly nature that can provide decent cleaning at a very reasonable price.

For that, we have created this iRobot Roomba 805 Robot Vacuum Review so you can check if it can suit your vacuuming needs.

Key Features Of TheiRobot Roomba 805 Robot Vacuum

At a fairly affordable price, the Roomba 805 comes with a number of features that can help you achieve decent results. While it’s devoid of the usual bells and whistles that the advanced Roomba models have, it surely is a robot vacuum that can do its job well.

Here are the key features that the Roomba 805 has:

1. AeroForce 3-Stage Cleaning System

One of the key features of the Roomba 805 is its 3-stage cleaning system which uses better suction and filtration to provide you with a cleaner home. As the name implies, it provides 3 layers of cleaning in one go.

The first stage includes the side brush which effectively sweeps your floors then place the debris in the robot’s path. The second stage includes the rubber extractors which collect dirt then separate debris to the air chamber. The third and final step involves HEPA style filters which collect particles that might cause allergies.

However, in an effort to reduce the robovac’s price, it only comes with a standard filter instead of a HEPA style filter.

2. Automatic Recharge

The Roomba 805 is fitted with a technology that monitors its current battery and RCON sensors which detect the charging dock when its battery’s about to die. Once its battery reaches critical levels, it will stop cleaning and find its way to the charging dock to recharge for 3 hours or until fully charged.

3. Scheduled Cleaning

Another notable feature of the Roomba 805 is that it allows you to set one cleaning schedule every day for up to 7 days. You even have the option to let the 805 continuously clean until its battery is almost depleted. Once the whole week is over, you will need to create another schedule.

Fortunately, the process of creating a cleaning schedule isn’t that complicated. The robot comes with a display where you can choose the schedule and duration of cleaning. This will cause the robot to clean your house during the specific schedule you set. Therefore, even if you’re out of your house, the robot will perform its job of cleaning your floors.

4. Dual-Mode Virtual Wall Barrier

In terms of containment options, the Roomba series has no doubt the most reliable method, thanks to their dual-mode virtual wall barrier, a feature that is present in the Roomba 805 as well. With this feature, you can set up a virtual perimeter where your robovac can freely go to. This also allows the device to sense any walls and obstacles while cleaning by setting it up via the battery-operated towers included in the package.

There are two options you can choose from: halo or linear. When you choose halo mode, the barrier will create a ring that extends up to four feet away. In linear mode, however, the tower will create an infrared beam that extends past entrances to prevent the robovac from passing through.

With this feature, you can set the limits where the robovac is allowed to go. This can be particularly useful if there are spots in your house where the Roomba might possibly get stuck. It’s also helpful if there are damaged areas in your house where you don’t want your vacuum to go to.

5. iAdapt Navigation

While the robovac’s dual-mode virtual wall barrier feature allows you to contain it in a single area, you might come across some issues if you just let it wander around your house. This has been a problem that most customers faced when using a robot vacuum.

To resolve this, the Roomba 805 uses iAdapt navigation which is the first generation of navigation sensors. It uses infrared and acoustic sensors that will allow the robot to move around your house. It also has drop sensors at the bottom which serve two purposes: to keep it from falling off stairs and to serve as dirt detection to alert the vacuum that an area requires further cleaning.

Apart from that, it also comes with touch sensors which prompt the robot that it’s approaching an obstacle, causing it to slow down. Once it comes into contact with the obstacle, it then uses a pressure sensor to check if it’s passable or not.

iRobot Roomba 805 Robot Vacuum Review

Now that you have an idea of the key features that the Roomba 805 has to offer, let’s move on to our comprehensive 805 robot vacuum review by talking about its performance, design, ease of use, and a few other aspects.


Like the other models in the Roomba series, the Roomba 805 has a round shape without any corners, allowing it to reach any corner without getting stuck. It has a 3.6-inch clearance which makes navigation under most furniture fairly easy.

It’s also very lightweight, at only around 8.4 pounds, and has a glossy upper portion which comes with operational buttons. In terms of construction, the device is made of high-grade plastic for excellent durability. 

Lastly, it has tangle-free extractors, like the other Roomba models, which are helpful in preventing clogging due to the accumulation of hair. Overall, it has a sleek design that comes in black and is slightly aesthetically pleasing as well.


The Roomba 805 can certainly hold its own when it comes to providing efficient cleaning. It can effectively clean carpets, though there are issues with getting around the dips and rugs. It also has adjustable brushes which allow it to clean hard floors without any problem.

Additionally, if you own pets, then the Roomba 805 is a perfect option since it can pick up anything, including pet dander and fur balls. However, you have to routinely clean its container if too much fur has accumulated to maintain its performance.

Unfortunately, the Roomba 805 struggles when it comes to deep cleaning. If you want a more effective robovac that can handle deep cleaning, you’re better off with the more advanced models.

Ease Of Use

The Roomba 805 is designed for new generation users. Therefore, it’s quite easy to use as it comes with easy controls which allow users to adjust its settings and modes based on their preferences.

Moreover, there’s no need to monitor the machine while it does its job. You simply have to set it to cleaning mode or schedule its cleaning routine.

A lot of customers who own the Roomba 805 liked it for its simplicity. It can even recharge itself, making the entire process automatic without requiring any intervention.


One of the most common complaints by customers who purchased a robot vacuum is that most of them tend to be too noisy when cleaning. Fortunately, that is not the case with the Roomba 805.

In fact, the 805 is one of the quietest robot vacuums on the market. It’s quiet enough that it can’t even sound over your TV or be heard in the background while you’re answering a call on your phone.

If you’re someone who gets irritated with a noisy vacuum cleaner, then you will surely appreciate the Roomba 805’s virtually noiseless operation.

Battery Life

The Roomba 805 comes with a built-in lithium-ion battery which lasts up to 3x longer than most conventional batteries. On average, you can expect the 805 to offer continuous cleaning for 60-80 minutes when fully charged. This continuous runtime is more than enough to efficiently clean a large area.

In the event it loses battery power, it will simply return to its Docking station and recharge itself for 3 hours until it’s full again. It doesn’t really require manual intervention just to recharge.

That said, it doesn’t have wireless communications which can limit your control options. Also, it only uses standard filters as opposed to HEPA style filters, so it won’t be that effective in terms of removing allergens.

Despite that, if you’re looking for a budget-friendly option that simply does it cleaning job, then you will surely appreciate the Roomba 805.
