Roomba 891, the robot vacuum cleaner that adapts to any surface

There are not a few who are increasingly opting for the purchase of a robot vacuum cleaner instead of a conventional sled or broom vacuum cleaner. This is because these robots have an autonomy that allows the user not to have to be attentive or fully involved in cleaning, thus allowing them to focus on other tasks and not have to worry about time. For this reason, we can find in the market, more and more frequently, this type of electrical appliance, although today we will talk about the iRobot and, specifically, the Roomba 891, which belongs to the 800 series and whose features are more than sufficient for the average consumer.

The Roomba 891 has a series of very interesting features that we will discuss below:

On the one hand, it has a maximized suction power which, compared to other robots of the iRobot brand, in its own Roomba model, in the 800 series stands out for displaying up to five times more power in aspiration than its predecessors. To this, in addition, a system of special brushless rubber rollers called AeroForceTM Pullers that, when the device sucks and sweeps, they make it impossible for hair and lint to get tangled, thus greatly facilitating the maintenance of the robot and increasing its useful life.
Although, if this robot vacuum cleaner stands out, it is in its iAdapt® system, which, as its name suggests, allows it to adapt to the needs of your home surfaces thanks to a patented cleaning system. With this, responsible navigation is achieved, since, although its movements and displacement are very random to the human eye, when it passes several times through the same site, it manages to remove the most persistent dirt.
For all this, it is a product highly recommended for pet owners or for those who suffer from allergiess. Inside the Roomba tank, both the model 890 and the 891, we find a HEPA filter very efficient that removes even the smallest airborne particles, making this robot an ally against allergies. And if, in addition, we add to this its special rollers, discussed above, we will prevent pet hair from returning to the environment and it will not remain embedded in the device.

Regarding the surfaces on which it works, the Roomba 891 is ideal for hard floors such as parquet, laminate, tiles and the like. In addition, it can also be used on carpets to remove dust and dirt. With its long side brush it moves and work along the edges and corners, and carries the dirt to the suction nozzle. This, together with its height of only 9.2 cm, which makes it a fairly low robot, makes it possible for the robot to gain in efficiency and meet the expectations of even the most demanding thanks to the fact that can be moved under furniture and vacuum where brooms or other vacuum cleaners cannot reach, such as beds or sofas. You also do not have to worry about the corners of the doors or the carpets, since it is able to overcome them with up to a height of 2 cm, which guarantees a cleaning without interruptions.

Finally, focusing on the technology that is incorporated, we can point out that this robot is equipped with numerous anti-obstacle sensors that will help you to recognize, for example, stairs or other objects that are in your path. This will allow you to change the direction at the right time and continue cleaning without the risk of rushing or hitting any piece of furniture.

In addition, we can control our robot thanks to the iRobot HOME App, designed for Android and iOS that you can download and, from that moment, use to start, stop, program and monitor your robot, with the addition of being able to set, for example, a day of the week at a specific time, even , so that the robot starts working automatically.

Opinions from the Roomba 891

This robot vacuum cleaner delivers on what it promises. Has enough suction power And it is highly recommended for dog and cat owners for its ability to retain and remove pet hair from the environment. In addition, this is also beneficial for people who suffer from allergies and can help you when you have a visit who has this condition.

However, and despite the fact that it is a robot that enjoys very good quality and popularity, we have to mention two points that we consider negative. The first is its price, because there are robot vacuum cleaners from other lesser-known brands with the same benefits and cheaper than this one and, second, is that it is ideal for a home of about 80 m2, but it is not as efficient in larger homes.
