iRobot Roomba i7+

Our detailed iRobot Roomba i7+ review - Is it worth buying the premium robot vacuum cleaner?

Our detailed review shows whether the iRobot Roomba i7+’s (i7558) premium features are worth their money.

The iRobot i7 Plus has some high-end features - we were thrilled with them!

The automatic emptying station and the sophisticated voice control definitely belong to them.

But do these convenient functions of the iRobot Roomba i7+ justify the very high purchase price? Or are there even better alternatives on the market?

We put the iRobot Roomba i7+ through the wringer in our test. Read on to see what we found out about this robotic vacuum cleaner.

iRobot Roomba i7+ vs. Roomba i7 - what's the difference?

The "Plus" in the Roomba i7+ stands for the self-emptying dust bin ("Clean Base") that comes with it.

The Roomba i7+ clean base hold on hands

You have to dig quite deep into your pockets for the i7+ (incl. Clean Base).

But if you can do without the auto-empty dust bin, the price is much lower.

All other functions and features are identical.

So the key question is: is the Clean Base (automatic dirt disposal) worth the money?

We’ll get to the bottom of that in the following chapters.

Automatic dirt disposal (Clean Base) - benefit or gimmick?

Long story short: The clean base (self-empty dock) is the highlight of the iRobot Roomba i7+.

The self-emptying dock of the iRobot Roomba i7+ stands on the floor.

The mobile dust container has a capacity of 460 ml and quickly fills up (depending on the degree of soiling in your flat). Therefore, you have to empty the mobile dust bin almost daily.

We can think of better ways to spend our time.

The Roomba i7 Plus takes that burden off your shoulders with its automatic dirt disposal.

But how does it work?

The Clean Base automatically empties the mobile dust container’s contents as soon as the robot vacuum approaches the charging dock. That takes about 8 - 10 seconds and is quite noisy.

Then it stores the dirt in an own dust bin at the top of the self-emptying base.

How the Roomba i7+ clean base works

The manufacturer states that the Clean Base’s dust container can hold up to 30 full loads of the mobile dust chamber.

That means it takes about 3-4 months until the dirt disposal bags are full in our 80 m² flat.

Inserting the dust bag into the Clean Base

You can easily buy a 6-pack of the Clean Base’s dirt disposal bags on Amazon.

The dust bag in the clean base is large and takes quite a long time to fill up, depending on how dirty your home is. If you have pets, it’ll fill up much faster.

It would have been better if iRobot had used a washable, reusable dust chamber instead of the disposable dust bag.

Our Tip: If you don't have any allergies, you can save some money and vacuum the dust bag in the self-emptying base with a conventional vacuum.

Vacuuming the dust bag in the Clean Base with a conventional vacuum

The charging station with the automatic dirt disposal is a true blessing for allergy sufferers.

You don’t have any contact with the house dust anymore (except when you wash out the mobile dust container).

All in all, we can say that the Roomba i7+'s clean base convinced us in the test. iRobot takes another important step towards automated cleaning with it.

We don't want to do without that convenient feature anymore. The Clean Base simply saves a lot of time and effort.

iRobot Roomba i7 (+) cleaning performance on different floor types: our review

Suction test on a hardwood floor

First, the iRobot Roomba i7 Plus had to deal with dirt on the laminate floor.

Overview table of Roomba i7+'s suction test result on laminate

Test result for lentils (removed 43g of 50g | 86 %)

The iRobot Roomba i7 Plus did a great job removing the lentils.

It only left a few lentils in the corners that are difficult to access.

Dirt remains in the corners during the lentil suction test

You can also find a few single lentils on the suction surface.

That’s because the fast-spinning side brush "flung" some light and grainy lentils across the room from time to time.

Test result for oat flakes (removed 45g of 50g | 90 %)

The Roomba i7 (+) also had no trouble with the grainy oat flakes.

It left a few flakes in the hard-to-reach corners and single bits in the room, too.

Test result with sand (removed 47g of 50g | 94 %)

The heavy sand is usually very challenging for all robot vacuums.

But the Roomba i7 came out with flying colours and removed a whopping 94% of the sand on the laminate.

iRobot Roomba i7 on carpets – our review

The Roomba i7 Plus doesn’t have an automatic carpet detection function. Thus, it also doesn’t increase the suction power automatically when it drives on a carpet.

It still achieved excellent results in our suction test.

The two rubber rollers rotate in opposite directions so that they thoroughly brush through the carpet. It’ll look super clean after the vacuuming trip.

Here’s a thoroughly brushed carpet after the iRobot Roomba i7 cleaned it.

Suction test result on the low-pile carpet:

Overview of Roomba i7 Plus suction test results on low-pile carpet

Suction test result on the high-pile carpet:

Overview of Roomba i7 Plus suction test results on high-pile carpet

Higher carpets usually pose a threat to robot vacuums.

But not so with the Roomba i7 Plus.

The robotic vacuum cleaner hardly reached its limits with the lentils (short carpet: 94%, long carpet 98%).

It's a great result.

The robot vacuum also didn’t have any problems with the oat flakes.

It removed 96% of the dirt on both short and high carpet, which leaves nothing to be desired.

iRobot Roomba i7 Plus removed almost all the oatmeal on a carpet

The heavy sand on the carpet is the biggest challenge for all robot vacuums.

iRobot Roomba in the sand suction test on the carpet

The Roomba i7+ does a great job here, too, and removes 60% of the sand on the short carpet and 70% on the higher carpet.

iRobot Roomba i7+ removed half of the scattered sand on the carpet

The percentages may seem relatively low at first, but the result is excellent compared to other top models.

The heavy sand sinks deep into the carpet, which is why robot vacuums have a hard time removing it.

Vacuum robots and conventional vacuums / cordless vacuums quickly reach their limits here and don’t score much better.

Plus, you have to keep in mind that our tests are extreme situations.

It’s doubtful that so much sand ends up on your carpet.

Your new household helper also vacuums the home much more frequently, which creates a permanent level of cleanliness.

The robotic vacuum cleans our home almost every day. Dirt can hardly accumulate on carpets or in corners.

The iRobot Roomba i7+’s cleaning performance is entirely sufficient for an average flat.

You will be thrilled!

Cleaning along skirting boards and in corners – our review

The robot vacuum did a great job cleaning along the skirtings and in corners.

iRobot Roomba i7+ cleans along the skirtings

However, the iRobot Roomba i7 obviously can’t achieve a perfect result in corners because of its round shape.

iRobot Roomba i7+ cleans in a corner

Since the Roomba i7+ probably cleans the home several times a week, dirt can hardly accumulate in the corners.

So it’s not a big deal.

iRobot Roomba i7 Plus vs. pet hair and human hair

Most robot vacuums have one combination brush made of bristles and lamellae.

The iRobot has two rubber rollers rotating in opposite directions ("dual brush system") instead.

Hardly any dirt gets caught in the brushes, thanks to brushes’ material and the opposite rotation.


Two brushes of the Roomba i7+

You can remove the two brushes by a simple "click mechanism" if some dirt (especially pet and human hair) should ever wrap itself around the brushes.

Then you can easily “pull out” the hair.

That reduces maintenance to a minimum, making the iRobot Roomba i7+ particularly suitable for pet owners.

Navigation and driving – our review

Create and save maps (smart mapping)

First, the Roomba i7+ has to create a map of your home. Then it can show what it’s got!

You don’t have to raise a finger for that (ok, maybe one).

Send the robot vacuum cleaner on its first cleaning job at the touch of a button in the app - it’ll do the rest.

The Roomba i7+ scans your home’s floor plan, so it theoretically knows your home once it finishes its first trip.

However, the map is not yet 100% complete, and some details are missing.

Our Tip: Clean up your home before the first time cleaning session so that no small items such as Lego bricks, clothes etc., are lying on the floor. These disturb the Roomba i7+ on its first trip :)

Oh yes - don't forget to open all the doors. Now the robotic vacuum cleaner can reach every spot in your home.

The map will be ready to go after 3 - 4 cleaning runs at the latest, so you can access it in the app.

You can edit them according to your wishes and set up individual cleaning processes.

Multiple floors? No problem. - iRobot Roomba i7 (+) can save up to 10 maps!

Roomba i7+ can create and save up to 10 maps.

That makes the iRobot Roomba i7 Plus also very suitable for houses/flats with several floors.

Unfortunately, the i7+ can’t climb stairs yet, but you can easily transport it from floor to floor, thanks to the convenient carrying handle.

Camera-based navigation

Good navigation is essential for a good cleaning result.

If the robot vacuum doesn’t have structured navigation and leaves out areas, the cleaning result won’t be satisfying.

The iRobot relies on camera-based navigation technology (iAdapt Navigation Technology).

Numerous built-in sensors (crash sensors, …) also support efficient navigation.

IAdapt technology systematically scans the flat.

The robot vacuum cleaner continuously calculates the fastest route and determines very precisely where it has already been and where it has to go next.

The Roomba i7 (+) is quite fast. The robotic vacuum took 40 minutes to clean our 80m² flat.

One slight drawback of the camera-based navigation technology is that the Roomba i7 takes a little longer in poor lighting conditions.

In absolute darkness, the iRobot Roomba i7+ can’t do its job.

But this isn’t a big deal since you’ll probably rarely use the robot vacuum at night - Unless you want to annoy your neighbours ;)

Obstacle detection

The obstacle detection works relatively well.

The Roomba i7+ recognises the position of objects by navigating with the camera. It checks and adjusts the created map in real-time.

With that, the Roomba i7+ can skilfully avoid most obstacles.

If the iRobot robot vacuum doesn’t recognise an obstacle, the bumper is here to help.

However, that happens very rarely. The robot vacuum cleaner is gentle with the furnishings. It certainly won’t damage them.

Our review of obstacle Overcoming and Precipice Detection

The iRobot Roomba i7+ overcame a height of approx. 1.9 cm in our test.

Roomba i7 crosses a doorstep

Thus, the Roomba i7+ climbs conventional doorsteps and smaller obstacles without any problems.

We only carry out our tests on hard 90-degree edges to keep objectivity, so we’re pretty sure that the robot vacuum can climb rounded edges/obstacles even better.

PS: We reveal which robotic vacuum cleaner can climb best in our article "Robot vacuums for high doorsteps in comparison".

The robot vacuum uses the usual abyss detection sensors to detect precipices.

We tested them with our stairs and also put the robotic vacuum cleaner on a table.

The iRobot Roomba i7+ mastered the task - It stops before a precipice and then takes off in a different direction.

Our Recommendation: You should clean the sensors once a week with a dry microfibre cloth to avoid any accidents ;)

Battery: runtimes and charging times

The Roomba i7 Plus has a 3300 mAh lithium-ion battery. With that, it can clean your home for about 75 minutes at a stretch and cover an area of about 100 m².

Of course, we tested that, too. The little household helper took about 40 minutes for cleaning our 80 m² flat. The battery status was still at about 50 %.

However, if the battery runs out during a cleaning session, that’s no problem either.

The robot vacuum remembers the exact spot where it has to interrupt its cleaning trip. The Roomba i7+ returns to this spot and continues cleaning ("Recharge & Resume") as soon as the battery is full.

Volume

The Roomba i7 Plus is exceptionally quiet...

...even though it has such an excellent cleaning performance!

We measured a volume of 63 dB in our test.

Measuring Roomba i7+’s noise levels

You can still have a conversation in the same room - while the robot vacuum is doing its work - but it’s not that pleasant. The same applies to watching TV in the same room.

But the robot vacuum won’t disturb you often - the little household helper usually does the work in your absence :)

Our review of iRobot Roomba i7+ App

The iRobot Home App is available for Android and iOS. (Wi-fi connection needed)

iRobot Home App

The iRobot app is another highlight of the Roomba i7 Plus. The app offers a lot of great features and is still super user-friendly.

Once the robot vacuum has created the map, you can use the numerous functions in the app.

As a reminder: It can save 10 maps!

You can edit the map however you like once it’s in the iRobot Roomba i7+ App. You can merge and separate rooms and also name the individual rooms.

This feature seems so simple, but hardly any other model offers it.

You can also set up individualised cleaning schedules. For example, you can let the i7 Plus clean the kitchen and living room on Monday, Wednesday and Saturday at 9 a.m.

You can exclude specific areas from cleaning by setting up no-go zones.

The delivery scope also includes a “virtual wall barriers” for defining restricted areas. However, you don't need the virtual wall since you can set up no-go zones via the app.

When the iRobot Roomba i7 came out, it wasn’t possible to create no-go zones. iRobot released an update for that afterwards, which is why the virtual wall is kind of out-of-date these days :)

Apart from that, you have the usual functions at your disposal:

● Language selection and voice output (You can select German, English and many other languages)

● In "History", you can view the individual cleaning processes, including data, statistics, etc.

● In the "Maintenance" section, you can see when you have to replace individual spare parts (brushes, HEPA filters, etc.).

Voice Assistant

The Roomba i7 plus is compatible with popular voice assistants Alexa and Google Home Assistant.

Here, the iRobot is ahead of its competition.

Communication isn’t limited to a simple "start", "stop", and "return to charging station".

You can use a variety of voice commands.

Voice commands on the iRobot Roomba i7+ Alexa

You also don't have to learn a sentence by heart and recite it the same way over and over again. The voice control is very sophisticated, and your Roomba i7 Plus understands variations of voice commands.

But what exactly can I do with it?

You can send the iRobot to clean a specific room, let it vacuum your bedroom first and then your living room. You can tell Roomba i7 Plus to clean your living room in the evening.

The voice assistant also asks clever and meaningful questions, such as: "Should I drive back to the charging station?", "Which room should I vacuum?" etc.

You have a wide range of options, and it's a lot of fun to communicate with your robot vacuum via a voice assistant.

Imprint Technology - Connect the Roomba i7+ to the Braava mopping robot

iRobot has another unique feature to offer. And it’s one of a kind.

You can connect iRobot devices via the "Imprint Link Technology".

At the moment, you can connect the Roomba i7 (+) and the Braava Jet M6 robot mop.

If you have both devices in use, you can let the Braava Jet M6 mopping robot start its trip as soon as Roomba i7+ has finished vacuuming.

Sure, it's pure luxury - you have to dig quite deep into your pockets for both robots. But all smart home fans will love this feature.

That’s another step towards fully automated cleaning.

Be Warned: Once you've had such a luxury, you won’t want to do without it anymore.

We speak from our own experience here ;)

Delivery scope, accessories and spare parts

The postman was quite out of breath :)

That’s because the Roomba i7+ comes in a rather large package.

iRobot Roomba i7+ packaging box

The delivery scope doesn’t just include the iRobot Roomba i7+ Robot Vacuum and the relatively large and very cool clean base. iRobot also added several accessories.

Delivery scope and accessories of the iRobot Roomba i7+

● 1 x HEPA filter

● 1 x HEPA replacement filter

● 2 x dust bags for the emptying station

● 1 x side brushes

● 1 x Replacement Side Brush

● A virtual wall

● Detailed operating instructions

It’s great if the manufacturer includes more than the absolute essentials in the delivery scope. You have spare parts (HEPA filter, side brush) quickly at hand if needed.

iRobot also includes 2 dust bags for the self-emptying dustbin in the delivery scope. You’re covered for a while now and won’t have to buy more.

Long story short: The delivery scope is generous! You can also order spare parts and accessories online on Amazon.

Design & Dimensions

iRobot relies on continuity in design. The manufacturer also doesn’t have any reason why it should change anything.

Nice to know: The Roomba i7+’s design won the coveted "Red Dot Award".

The robot vacuum still has a round shape. The dimensions are: width: 34.2 cm x length: 34 cm x height 9.3 cm. It weighs 3.38 kg.

Measuring the iRobot Roomba i7+ with a ruler

The Roomba i7+ is only available in one colour combination (black with grey accents).

The robot looks excellent - that’s for sure. Nevertheless, it would be better if there were also other colours.

A dark robotic vacuum cleaner may not fit into every flat in terms of colour.

You can operate the following touch screen buttons at the robot vacuum’s top: "Clean" (2) (start/stop cleaning process), "Home" (3) (return to charging station) and "Spot Clean" (1) (clean one precise spot).

There’s also a camera at the top that ensures excellent navigation.

Furthermore, the smart vacuum cleaner robot also has a convenient carrying handle (4), so you can easily carry it from floor to floor.

There are three touchscreen buttons on the top of the Roomba i7+.

The dust container is not inside but at the back of the robot vacuum.

You can easily remove it by pressing a button.

iRobot stands for premium quality. The Roomba i7+ is no exception.

The device has an excellent finish and looks very classy. The materials used seem to be of very high-quality.

Dimensions, design and weight of the charging dock (clean base)

One thing is for sure: The iRobot Roomba i7+ Clean Base is an absolute highlight.

It has a long power cable, including a cable management system, at the charging dock’s back.

The self-emptying clean base of the iRobot Roomba i7+ from behind

The robot vacuum can charge whenever it docks at the Clean Base, which also automatically empties the mobile dust container.

The clean base has the following dimensions: height: 48 cm x depth: 15 cm x width: 18 cm.

Measuring the Roomba i7+ clean base with ruler

The clean base, including the automatic dirt disposal, is somewhat larger than a conventional charging dock.

The iRobot Roomba Clean Base next to the Roborock S5 Max charging station.

However, the Clean Base looks very classy (like the robot itself) and is an absolute eye-catcher.

Visitors frequently ask about the auto-empty dock and the robot vacuum. They’re even more amazed once we show the Roomba i7+ and the self-emptying process live :)

Price-Performance & Conclusion

One thing’s for sure: iRobot devices in general - and the iRobot Roomba i7+ in particular - are high-priced luxury products.

But the Roomba i7 Plus Robot Vacuum also offers excellent performance paired with premium features.

The sophisticated voice control and the self-emptying dock (<clean base) are the highlights. The latter function automates the cleaning of your flat almost entirely - There’s virtually nothing left for you to do.

The Roomba i7+ is quite expensive. If you can do without the clean base, you won’t have to dig that deep into your pockets.

You have to decide for yourself whether the luxury of the self-emptying base is worth the higher price. We hope our iRobot Roomba i7+ review helps.

The iRobot Roomba i7+ and especially the clean base came out with flying colours in our test!

However, if you don't need all that luxury and want to save some money, the models from Roborock (Roborock S5 Max Review, Roborock S6 Review) or Ecovacs (Deebot OZMO T8 AIVI Review, Deebot Ozmo 950) might be a better choice.

  • The Side Brush


    You can see the side brush on the front left, as usual.

    We noticed that sometimes - very rarely - the brushes scatter a bit of lighter dirt in the room on hard floors during our tests. We think that’s because the side brush rotates quite quickly.

    However, that’s not a big deal.

    All in all, the side brush reliably transport the dirt to the suction opening under the vacuum.

    A few hairs get caught in the side brush from time to time. You can easily remove them with scissors.

  • Dirt Detect Technology


    The intelligent household helper automatically detects during cleaning whether a particular area is more heavily soiled, thanks to special sensors.

    The so-called "Dirt Detect Technology" ensures that the robot vacuum cleans that area more thoroughly. The iRobot Roomba i7+ moves back and forth several times for better cleaning results.

  • Navigation under objects


    The Roomba i7+ doesn’t rely on laser-based navigation technology

    This way, the Roomba i7+'s overall height of 9.3 cm is slightly lower than many of its competitors.

    Measuring the height of the iRobot Roomba i7 with a ruler

    Besides, you don't have to pay so much attention to the sensitive navigation tower.

    That makes the Roomba i7+ easier to handle, and its low-profile design gives it an advantage over competitors.

    Our Tip: As always, please check carefully at home whether the Roomba i7 (+) can drive under the furnishings.

    If they’re a few centimetres too low, you can lift your couch with furniture raisers (available on Amazon).

  • Is it possible to connect it with other smart home devices via IFTTT?


    You can integrate the Roomba i7+ into various smart home use cases via IFTTT.

    That’s a nice extra for all tech enthusiasts :)

  • Mobile dust bin


    The mobile dust bin is at the back of the robot vacuum.

    You can remove it via a simple click mechanism.

    Attaching the mobile dust bin to the back of the iRobot Roomba i7 Plus

    The dust container has a capacity of 460 ml. You can easily open and empty it at the touch of a button.

    The mobile dust container opens at the touch of a button

  • Cleaning and maintenance tips


    We recommend cleaning the mobile dust container once a week under lukewarm water and letting it dry on a towel.

    Cleaning the Roomba i7+ i7558 dust bin

    Attention: Take out the HEPA filter first. You shouldn’t wash that.

    Please make sure that the dust container is completely dry before you reattach it.

    The robot vacuum uses the side brushes very often and intensively, so they wear out relatively quickly.

    Replace the side brushes at regular intervals to keep a consistently good cleaning result. If the bristles look frayed, stick out in all directions, and you notice that the cleaning result is decreasing, it’s high time for a change :)

    You should tap out the HEPA filter once a week over a dustbin or sink. We also recommend replacing the HEPA filter after approx. 4 - 6 months.

  • Does the iRobot Roomba i7+ use a HEPA filter?


    Yes, the iRobot Roomba i7+ has a HEPA filter. This HEPA filter filters even the smallest dirt particles from the air.
