iRobot Roomba 805 Vacuum Review of features

A smart vacuum cleaner

This Roomba model is a smart device. It can move automatically, thanks to its integrated sensors. Using a map and a visual location, it moves linearly. In the center of the camera is a camera inclined at 30. It is used to identify the different obstacles in your home. This can be furniture or other equipment. Thanks to its technological system, displacements do not take place randomly.

This unit is also equipped with infrared sensors and a bumper. In case he detects an obstacle, he goes around it slowly. It is also equipped with vacuum sensors with its Cliff Detect function. This avoids accidental falls. With the Dirt Detect system, this vacuum cleaner can locate the dirtiest places. Thus, he spends more time cleaning them effectively.

Its optical sensors

The iRobot Roomba 805 vacuum is a robot that quickly made a name for itself. Indeed, it is one of the smartest and most efficient models on the market today. And even if it is also one of the most expensive, you can be confident with quality and longevity.

Unlike some models, it does not have a camera. On the other hand, the manufacturers compensated this lack by a pair of acoustic and optical sensors.

Thanks to the optical sensor, this robot is able to identify by itself the largest debris. The acoustic sensor, meanwhile, can detect the smallest waste. In concrete terms, he will be able to identify all the dirtiest areas and decide for himself whether he should insist on certain parts or not.

So you can let him work independently while you do other things.

It's management of obstacles

Although I have read some users have found the blind navigation of this model tricky, I had the opposite experience. This unit navigated obstacles really well in my house.

The proof, when we passed it under a coffee table, the iRobot Roomba 805 was able to circumvent all the obstacles that stood up against him, in a very methodical way. During the first test, you will also see that it passes several times on the dirtiest areas to provide a flawless result.

You will also be surprised to know that this model can be used for cleaning your stairs. It easily avoids the pitfalls without difficulty. He will walk along the steps without falling into the void. Another point that has the advantage: the ability to manage heights. Whether low or high areas, the result will always be there.

Its noise and its suction capacity

Unfortunately, this model is a bit noisy. On hard ground, the noise level is 68 dB. On a carpet, this level drops to 66 dB. However, it is important to note that this machine can work in the absence of the inhabitants of a house.

Which means you will not be bothered by this noise, in your absence. And even if the iRobot Roomba 805 has a voice, it does not interfere with the suction quality.

This product uses a cleaning process that is divided into 3 very specific steps. At first, the rotating side brush will clean the floor. The vacuum cleaner can then pick up the debris thanks to the intervention of the Dirt Detect technology. And the last step is to put all the debris in a single tank without an integrated bag.


If this vacuum cleaner robot is so popular, it is mainly thanks to its very full technical sheet. In particular, its suction power is estimated at 25W, while its autonomy is 120 minutes.

Thanks to these features, its manufacturers ensure that it can easily handle an area of 80 m². Note that the model is equipped with a 2600 mAh Li-Ion type battery, which can be recharged in just 3 to 4 hours.

On the other hand, the 60 dB emitted by the device make it a relatively quiet robot. In all discretion, therefore, the robot vacuum also offers the washing function. With its 300 ml tank, it can effectively wash tiles or floors. In addition, you can also use the simple sweeping function for simple dust extraction.


This 2-in-1 robot vacuum cleaner also appeals for its compactness. In fact, its dimensions are 30 cm in diameter, for a height of 7 cm. A size that will allow it to move almost everywhere, even in every nook and cranny under the bed or sofas. Its weight is only 4.7 kg.

In the case of unstable floors, the model is equipped with road wheels to further optimize cleaning.

In addition, the device incorporates an LCD screen for easy adjustment. You will even find a remote control that will allow you to control the entire device from a distance. 3 settings to choose from include a random cleaning, a circular cleaning or on the edges of the walls.

Better yet, the user can schedule the cleaning during his absence through the timer.

Modern technologies

To perfect its cleaning system, the manufacturers of this model have integrated several very useful technologies. For example, thanks to the different obstacle sensors, the robot can easily detect stairs or difficulties in its path. This is to prevent accidental drops.

In its dustbin, we find a HEPA filter for a total removal of the smallest particles. Whether hair, mites or animal hair, this model promises to eradicate everything. The 2 built-in brushes further promote the cleaning action.

Best of all, manufacturers have added microfiber cloths to the product. These accessories can be attached to the base of the robot to wipe the washed surfaces after using moisture maintenance.

Are vacuum robots suitable for older people and seniors?

Due to the very simple operation, they are very suitable for the elderly. For most models, you just have to press a button after charging and the vacuum robot starts to work automatically.

Does the robot work on all floors?

The robotic vacuum cleaner cleans easily all surfaces such as carpet, parquet, tiles, and laminate. He automatically recognizes which floor he is on and optimizes the cleaning process. An exception is black or very dark floors.

Unfortunately, the robot does not work here because it interprets the black color as an abyss and does not drive the area. And even with very high-pile carpets, the Roomba has difficulties, because the carpet hairs get tangled up in the wheels and brushes.

Robot Vacuum Purchase guide


If you’re wondering how to buy a Roomba Robot Vacuum cleaner at a better price, you’ll need to look at the features of the device. You should know that robot vacuums are used more to clean the house to save time cleaning and to track dirt and dust. Because of this, it is better to choose a device that offers more useful features for more performance.

However, no need to have a device riddled with different modes: the key is to have at its disposal a device that smart, effective and autonomous at a time. It is, therefore, preferable to choose a model Roomba robot vacuum programmable and/or controllable from a smartphone using an application.

The navigation system of the device is also a point not to overlook if we look at the features of the device since it is thanks to this that the robot could cover the entire room to clean or not. A model integrating a camera, or a laser range finder would be ideal since it could map the room to clean it in a systematic way.

A device capable of handling obstacles is also a good device, off-road wheels, multiple sensors: the bottom line is that it can perform its tasks without getting stuck on an obstacle.

Noise and consumption of the device

Another feature to consider when buying a new Roomba robot vacuum cleaner is the noise emitted by the device and its consumption. Our buying guide for the best robot vacuum cleaners Roomba offers you to make sure to choose the best device with lower consumptions.

Indeed, it is recommended to choose a device that does not consume a lot of energy to minimize the monthly electricity consumption. As for the noise emitted by the device, it will often vary according to the cleaned surfaces or the mode used, however, this one should not pose much of a problem since it is autonomous and can work without having to resort to your presence

Easy maintenance

In addition, be sure to choose a Roomba robot vacuum that is easy to maintain. Some models inherit the AeroForce system. The HEPA filter with a small tab is also easy to remove, which also facilitates its maintenance as it collects a lot of dust and will need to be cleaned from time to time.

After combing through these basic features, you are given the opportunity to move on to the essential question: “where to buy a new Roomba robot vacuum cleaner”? You will find models with prices that vary depending on the chosen Roomba robot vacuum cleaner model.

When comparing different models, do not forget to evaluate the following characteristics:

Evaluate your needs

It is very important that you take into account your needs and circumstances in regard to cleanliness. For example, if you have pets, you will be interested in a robot that is efficient at picking pet hair. If you have carpets, you will be interested in one that can overcome this obstacle without having to pick up the carpet every time you put the vacuum cleaner to work.

Evaluate the distribution of your house, size of it, rooms, possible obstacles for the robot such as doors, steps, furniture, carpets, etc. This analysis depends on whether you should buy a basic robot or another that has the necessary sensors to avoid obstacles.

Navigation system

You must be on alert with this; not all robots have a navigation system, so they are “aspiring” at random and may not clean the entire area. We recommend a robot that has a navigation system or that follows a pattern of the area to be cleaned.

Autonomy time

Another of the most important characteristics when evaluating the different options of robot vacuum cleaners is their autonomy time, that is, the time the battery lasts, especially important if you have a house or a large floor. Also check the charging time of the battery and charging system, if the same robot returns to its charging base automatically when it is running out of charge.

Deposit size

The size of the vacuum robot deposit is also linked to its autonomy because if it is filled, the robot will not work, so you should be clear that it is large enough to clean your entire house without having to stop the process to empty it.

Parts warranty

If you want your robot vacuum cleaner is really a long-term investment, buy a reliable brand, which can provide spare parts if you need, especially parts such as brushes, sensors, batteries that tend to wear out over time.

Extra features

Bet on buying a robot vacuum cleaner with more clear benefits that will mean paying a higher price, but it will also allow you to have access to very useful features:

HEPA filter: As in a normal vacuum cleaner, having a good HEPA filter will allow the appliance to inhale even smaller particles and it is really indispensable if you have pets and you want your hair not to be all over your house. In addition, this filter has a “purifying” function of the air that is highly recommended when you have allergies.

Virtual walls: When you live in a studio or have very large areas such as the living room and the dining room together, having the possibility of creating virtual walls allows the robot to concentrate on cleaning a certain area.

Programming: This is one of the characteristics that most value those who have a robot. In some models, you can program the day and time of cleaning, and even in the most advanced you can define the area to be cleaned by defining virtual walls; your robot will clean up even if you’re not at home.

Dirty degree detection: You can find models that can detect the degree of dirt and thus select the pattern and time of the cleaning program.

Sensors: Depending on the model of robot vacuum cleaner that you choose, you will have more or less sensors. Some of the most important sensors are those that prevent your robot from hitting your furniture to prevent damage to furniture or sensors that detect changes in height that make the robot change direction if it detects that there is a step.
