The iRobot Roomba j7 review: the robot vacuum cleaner that learns from you

All the robot vacuum cleaner they are equal? Not really. In reality there are a lot of elements that can differentiate them: power, navigation, ability to withstand shocks, application … In short, they perform the same function but do not fulfill their duties in the exact same way.
For example, iRobot Roomba j7 boasts a sophisticated system that allows it to improve its performance over time, learning to distinguish temporary obstacles from permanent ones. How? We tell you about it in this review.

The review of iRobot Roomba j7

There is a camera!

The first thing you will notice of iRobot Roomba j7 is probably the presence of a camera, embedded in the bumper and accompanied by an LED. What are these two elements for? Simple: they allow the Roomba j7 to improve its navigation system – that’s what it’s called PrecisionVision – and to obtain a more accurate house mapping, with the LED that illuminates the road to allow your robot to move easily even in the dark.

How does all this affect everyday use?
First of all iRobot Roomba j7 manages to optimally reconstruct the floor plan of your home, obviously referring to the surface that can actually clean.
Secondly you will notice fewer bumps and above all a great ability to adapt because the Roomba j7 continues to scan its surroundings, noticing any changes. In short, if you move a piece of furniture, if you place a box in the middle of the living room, if you add a piece of furniture, he understands it and asks you how to behave.
Yes, you got it right. Qhis robot vacuum cleaner interacts with you. And it does by taking a photo and sending it to you on the iRobot Home application; at that point you will have to tell him how to behaveso he’ll know what to do next time.

The iRobot Home application

But the application also takes care of making iRobot Roomba j7 smart iRobot Home.
It is extremely simple to use, with particularly intuitive menus and functions.
First of all it tells you if the robot is charging, if the battery is full and where it is. Second you can view the map and modify it, with dividers that allow you to create and rename individual rooms. You can also define zones to be excluded or cleaned.

What is the purpose of all this work that you are going to do on the map? To send Roomba J7 the well-defined points, also creating specific routines.
For example, you may decide to send your robot under the dining table every night at 9.00 pm, after dinner. So he will just pass through that area to collect the crumbs and then go back to the base.
You can of course also set more general operations, requiring it to clean every morning at 9.00. Or you can ask him to avoid the bedroom on Saturday and Sunday mornings so you can sleep undisturbed.
Then there are more automations based on your locationwith the iRobot Roomba j7 that can start cleaning when you leave or come home.

The app also packs the chronology, so you can check the Roomba J7’s activities, and The messages, with useful tips for using the robot itself.
Also through the application you can connect the iRobot Roomba J7 to Google Assistant, Amazon Alexa e Siri, so as to also take advantage of voice commands.

iRobot Roomba j7 review: how does it clean?

On the underside of the robot we find counter-rotating brushes with patented AeroForce technology and the inevitable side brush.
We then have a series of sensors that allow it detect carpets, avoid falling down stairs and understand areas to focus on. In fact, J7 is able to identify the dirtiest areas, which allows it to waste less time on areas that may already be clean and instead invest more resources in the areas that require it.
All these elements make it possible to guarantee an excellent level of cleanliness, with a system that allows him to automatically adjust the suction power depending on the surface and the amount of dirt.

AeroForce technology also makes it possible to suck up hair and hair without it being rolled around the brushesso you don’t have to worry about releasing them every time.

iRobot Roomba j7 also performs well on carpets, both long-haired and short-haired, but pay attention to small and light ones because they will inevitably be overwhelmed by the robot vacuum cleaner. We therefore recommend that you remove them before cleaning.
On the other hand, no problem for the larger carpets, which are recognized as such and marked on the map.


Autonomy is of about 80 minutes.
To help you understand what it means, let’s try to give you an example.
For a house of about 50 square meters it takes 40 to 60 minutes to complete the cleaning. This means that a single cycle is sufficient even for somewhat larger homes.

But what if it downloads before it finishes? It automatically returns to the base, recharges and then picks up where it left off.


We conclude with the design.
Here iRobot Roomba j7 does not surprise us particularly since its appearance is in line with that of other family members, with a front bumper that softens shocks, the start button in the center of the top, surrounded by a status LED, and the rear that instead houses the tank, designed to be removed and emptied easily.

We point out that inside the package you will find both a second filter and a second side brush, so you have a spare if you want to wash them or in the event of an unlikely breakage.

The review of iRobot Roomba j7

There are two versions of this robot vacuum cleaner: the one we tested, then iRobot Roomba j7, for sale at 749 €and the Plus model, which also includes the Clean Base for self-emptying and which you can find on the market for € 999.

These are undoubtedly challenging figures but yes, this investment is worth it. Roomba j7 is very easy to install, adapts to changes, can be controlled both from the app and via voice commands, cleans great and never needs your intervention. It just asks for some feedback through the iRobot Home app to better deal with the obstacles it detects.
In our opinion it is absolutely promoted.
