Ecovacs Deebot OZMO T8+ UK Review (2024)

The automatic obstacle detection (TrueDetect 3D technology) is undoubtedly the most exciting innovation.

The vacuum-mopping robot has a cross laser at the front, which scans the floor step by step. The 3D camera analyses the "disruptions" of the laser. That’s how it identifies obstacles.

That’s how it can identify even flat objects (such as mobile phone charging cables, children's toys, socks or slippers)...

…and avoids these obstacles automatically.

TrueDetect 3D obstacle detection review

We spread various objects (very flat as well as higher ones) on the floor...

...to test the obstacle detection of the OZMO T8+.

Review 1: Flat Objects

• Mobile phone charging cable (rolled up): Detected and avoided.

• Mobile phone charging cable (unrolled): Detected and avoided. However, the side brushes slightly touched the cable when turning around.

• Socks: Detected and avoided.

• Key: Detected and avoided.

• Hair clip: Detected and avoided. It slightly touched this obstacle with its side brush when turning around.

We were very impressed. The rate of detected obstacles was 100%.

The Deebot OZMO T8 only slightly touched the obstacles with its side brush when it drove around them.

Review 2: Higher Objects

• Shoes: Detected and avoided.

• Slippers: Detected and avoided.

• Toys: Detected and avoided. The side brushes slightly touched the object when turning around.

• Trousers: Detected and avoided.

• T-shirt: Detected and avoided.

• (Curtains): Detected and avoided.

100%! Another outstanding result.

The T8+ identified all scattered objects and avoided them.

Who profits from this technology?

If you live in a large household with children and/or pets, it’s almost impossible that there won’t be a single object lying on the floor.

The robot vacuum cleaner might accidentally suck up one of the objects (e.g. a sock or mobile phone charging cable) during the cleaning. Then the brush blocks and you have to help your little housekeeper. Until then, it won’t be able to resume the cleaning.

Thanks to the automatic obstacle detection, there’s only a meagre chance that this might happen to the Deebot OZMO T8+.

It will automatically recognise and avoid all objects that are lying around.

That way the robot vacuum cleaner can still clean the flat, even if you didn’t clear it up. It won’t suck up any object that might be lying around.

Conclusion on the obstacle detection function

We were very impressed with the "TrueDetect 3D" obstacle detection function.

So far, it’s the best obstacle detection technology of all our robot vacuum cleaner reviews.

It detected 100% of the obstacles!

The speed at which the robot vacuum found its way around the obstacles was also astonishing.

Can I be 100% certain of the technology?

We wouldn’t go out on a limb.

It won’t turn off the side brushes when "curving around" objects. It happens from time to time that the rotating brushes might “touch” an obstacle.

It could happen that the Robot Vacuum Cleaner "gets stuck" on, e.g. a mobile phone charging cable (it didn’t happen in our case though).

And suppose there are many objects close to each other (e.g. in an untidy children's room). In that case, the T8+ might get "confused" and will have some problems with "navigating" between the obstacles.

Once you activate the TrueDetect technology, the navigation time is also longer. But that’s pretty self-explanatory. The robot vacuum has to avoid obstacles, which results in a longer cleaning time.

To sum it up:

The automatic obstacle detection of the Deebot OZMO T8 works exceptionally well.

The OZMO T8+ takes a lot of work off your shoulders, especially when you live in a bigger and more "chaotic" household.

The Ecovacs Deebot OZMO T8 Plus has to show what it’s got in our vacuum test.

To do this, we let the robot vacuum go off on different types of dirt that we weighed out very carefully.

We do this on different surfaces: Laminate, short pile carpet and long pile carpet.

And as if that weren’t enough:

We also checked out the cleaning performance of the robot vacuum cleaner in our home.

Some details of the Ecovacs Deebot OZMO T8:

• 4 different suction modes (Quiet, Standard, Maximum and Maximum+). We always use the maximum suction level for our tests.

• 2000 Pa. Suction power

• The mobile dust container has a capacity of 430 ml

• HEPA filter and pre-filter included

• 2 side brushes with bristles

• Main brush with lamellas and bristles

Review on Laminate

The first challenge that awaited the Ecovacs Deebot OZMO T8 was on the laminate.

Review result for lentils (47 of 50 g absorbed | 94 %)

The OZMO T8 didn’t have any issues with the grainy lentils.

The robot vacuum removed an astonishing amount of 47 of 50 g (94%).

The two side brushes rotate at a reasonable speed so that it doesn’t scatter the light lentils in the room.

Test result for oat flakes (48 of 50 g removed | 96 %)

The oat flakes didn’t pose a threat to the Ecovacs robot vacuum cleaner.

The OZMO T8 only left behind 2 g of the oat flakes.

And the little housekeeper only missed them because they were in the corners.

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

Even the heavy sand was child’s play for the Deebot OZMO T8.

The little household helper hardly reached its limits here.

It’s a more than decent result that it only left behind 3 g.

Ecovacs Deebot OZMO T8 Plus - Suction test on carpet

The Deebot set the bar pretty high with its outstanding results on the hard floor, so we were curious how it would cope on the carpet.

Carpets have always been a challenge for vacuums. Especially fine, heavy dirt quickly sinks deep into the carpet, so the robot vacuum has a hard time removing it.

For that reason, the Deebot OZMO T8 has a reliable carpet detection function.

As soon as the robot vacuum moves over a carpet, the special sensors detect that. It automatically sets the suction power to the highest suction level.

Suction test result on low carpet

Result on high carpet

It removed the grainy lentils equally well on the low and high carpet.

The Ecovacs vacuum-mopping robot only left 1 g behind (it vacuumed 49 of 50 g).

There wasn’t a big difference to the oatmeal suction test.

It removed a total of 92% of the oat flakes on the short pile and long pile carpet. 4 g were left on the carpet.

Test result for sand

Sand and carpet...

..they don’t get along very well - at least that’s what vacuums think.

The robot vacuum has some great difficulties removing sand from carpets. The reason for that is that the heavy and fine sand sinks in quickly and settles in the carpet fibres.

Short pile carpet: sand test result (44 of 50 g | 88 %)

The result on the short pile carpet caught us off-guard.

Long pile carpet: sand test result (38 of 50 g | 76 %)

From our experience, we can tell you that this is still a good result, considering that it was sand on long pile carpet - the fear of all vacuums.

What do the test results of the sand on carpets (short pile / long pile) mean?

Long story short: it’s very good!

You’ll have a hard time finding a robot vacuum cleaner that has a better performance here.

Cleaning performance in everyday life

We didn’t stop after we put the Deebot OZMO T8+ through the wringer in our tests. It also had to prove whether it lives up to our expectations in everyday life.

Therefore, we put it to the test in our flat for a longer period of time.

In our 80 m² flat (mostly hard floors), the vacuum-mopping robot’s performance was exceptional.

The cleaning performance was impeccable. It reliably cleaned up our everyday dirt.

We have nothing to complain about.

Due to the excellent navigation, the Deebot OZMO T8 gets very close to the skirtings.

The long side brushes reach dirt along the ledges and transport it towards the suction opening.

And what’s the cleaning result like in corners?

Also very good.

A round robot vacuum cleaner cannot deliver a 100% perfect cleaning result when cleaning corners due to its shape.

A robot vacuum cleaner cleans your home much more often than if you’d do it with a regular vacuum. Therefore, much less dirt will accumulate in the corners.

Good navigation is essential for excellent cleaning results. It must be structured, fast and, above all, seamless.

After all, what’s the point of having a robot vacuum cleaner with good suction power if it "wanders" around for hours and leaves out areas/rooms?

It won’t do any good.

The Ecovacs Deebot OZMO T8+ has to create a map of your home to show its full strength in navigation.

Map creation and saving

Unpack your OZMO T8+ and charge it. Then you’re good to go.

The vacuum starts its first cleaning adventure in your home.

It creates a map in the meantime.

In the mobile app, you can watch it "live" as the robot hoover creates a detailed map of your home step by step.

It took about 53 minutes until it created the entire map of our 80 m² flat (~40 m² cleaning area).

The OZMO T8+ divides the rooms independently. You’ll see the individual rooms in different colours. If you are not satisfied with it, you can manually divide and merge rooms in the mobile phone app.

Now have a detailed map of your flat.

Now you can customise the daily floor cleaning as you wish (set up no-go zones or no-wipe zones, individual room cleaning, timer function, etc.). You can find out more about this in the chapter "Control (App and Co.)".

You can save several maps for several floors

The Ecovacs Deebot OZMO T8+ can store two maps.

That makes the vacuum/mop robot from Ecovacs very suitable for houses/flats with several floors.

You only have to activate the function "Multi-Storey Maps" in the menu item "Map Management".

To create the map of your second floor, you have to move the Robot Vacuum Cleaner with its charging station to the second floor. Then it will start cleaning as usual.

It will clean your second floor and create a second map of the new floor simultaneously.

At the end of the cleaning process, you can see the new map in the mobile app.

Now you can edit it as you wish.

PS: You have to place the charging station on the second floor only for the first cleaning to create a map.

Next time, just place the robot vacuum on the second floor and press the cleaning button. The OZMO T8+ knows its way around and automatically uses the right map.

Precise Laser Navigation

The Ecovacs Deebot OZMO T8+ uses laser navigation.

The laser is in the laser tower.

The laser also has a time-of-flight sensor (ToF). This makes it much easier to estimate the distance of obstacles.

That’s what makes the navigation of the OZMO T8+ extremely precise and structured.

Furthermore, the bumper of the robot vacuum cleaner basically won’t come to use. And even if, the slight "bumps" are entirely harmless.

The Ecovacs Deebot OZMO T8+ is quite fast. It took just 38 minutes for our 80m² flat (TrueDetect 3D technology was deactivated).

When you activate the TrueDetect 3D obstacle detection function, the Deebot OZMO T8+ moves a little more cautiously. Therefore, navigation takes quite a bit longer (approx. 45 minutes).

Operation with buttons on the robot vacuum cleaner

There is one button on the robot vacuum cleaner itself.

With this, you can start/stop the robot vacuum cleaner and send it back to the charging station.

With this, you can start/stop the robot vacuum cleaner and send it back to the charging station.

Mobile App

If you want to enjoy all the bells and whistles of the Deebot OZMO T8+, you have to use the mobile app.

The "Ecovacs Home" App is available for Android and iOS. You can download it for free in the app store.

Installation and Commissioning

Setting up the mobile app is super easy and takes about 5 minutes.

Ecovacs also provides concise step-by-step instructions so that you’ll be just fine.

First, you need to register with an email address and password.

After that, you have to add the robot to the app. You just have to scan the QR code hidden under the vacuum cleaner’s cover.

Finally, you have to connect it with your Wi-Fi. To do this, select your Wi-Fi network and enter the password.

That’s it. Now you have access to the comprehensive range of functions of the app.

After you’ve connected it to the wifi, the app will prompt you to download the company update. It adds some new functions and bug fixes.

After the software has been downloaded, the robot vacuum cleaner is ready to go so you can send it on its first cleaning trip.

Functionality of the app

The app offers many useful functions and setting options that simplify daily cleaning.

The update in September 2020 has its perks. Now you’re able to set the suction level and the water level for your flat’s room individually.

Furthermore, you can choose whether you want to clean the room twice.

In practice, it went really smoothly.

Once the OZMO T8 crosses the door threshold from one room to the other, it immediately changes the suction mode.

Another feature that we liked very much was the set up of no-go zones. You can mark general "no-go zones" (neither vacuuming nor wiping) and also select "no-wipe zones" (no wiping here).

A very nice feature is that you can zoom in and out of the map as you like. In this way, you fumble around when setting up restricted areas.

Here’s an overview of the other features of the Ecovacs Home App:

• TrueDetect 3D (On / Off): Activate and deactivate the automatic obstacle detection function.

• Carpet detection (On / Off). The suction power automatically increases when driving over a carpet once the carpet detection is activated.

• Creation of a cleaning schedule. Useful and above all, extremely simple feature. You can create the entire cleaning schedule for the week within a few seconds.

• Room labelling. You can assign symbols to the individual rooms (e.g. bathtub for the bathroom). Very practical for the overview but also for voice control with Alexa (see next chapter).

• Room division / room merging: You can manually set up the room partitioning if you aren’t 100% satisfied with the automatically created map.

• Spot Cleaning: Let the Deebot OZMO T8 clean a specific spot in your home.

• Suction power mode: You can choose the suction power setting for each room individually. 4 levels are available.

• Controlling the water flow rate: You can choose the water flow level for each room individually. 4 levels are available in the mopping function.

• Deep scrubbing: If you activate this feature, the Deebot OZMO T8 will scrub the room twice.

• Double cleaning: The Robot Vacuum Cleaner will vacuum the room twice.

• Silent mode: Set times when you don’t want the OZMO T8 to work.

• Multiple maps saving: You can save a total of 2 maps (for 2 floors).

• Cleaning logs: Here, you can view data and statistics on the last cleanings.

• Maintenance: Here, you can see how you should maintain the Robot Vacuum cleaner’s parts. You also receive a notification here about when it’s time to replace a specific part (e.g. cleaning brush).

• Language selection: Select the language in which you want to communicate with your new household helper.

• Select your location (UK)

• Set the volume of the voice output

Conclusion on the App Control

The Ecovacs Home App is one of the best applications available on the market for robot vacuums.

One small quibble is the app speed. It may take a few seconds until the robot vacuum cleaner shows up as "online" or until the window opens when you choose a feature.

This happens very rarely and is just "big-time whinging".

Otherwise, the app is excellent.

The range of functions leaves nothing to be desired.

Furthermore, the app is very clearly and intuitively designed. You’ll know your way around after only a short time.

Another nice extra:

Ecovacs is continuously trying to improve the app. New functions pop up (e.g. setting the suction power/water intensity per room) and bugs are fixed regularly. Only very few manufacturers offer such a service.

Long story short:

An excellent app that makes your daily floor cleaning much more comfortable with its numerous useful functions! You’ll have lots of fun with it.

Voice control with Alexa

You can also control your Deebot OZMO T8+ by voice.

We tried this at home with Alexa.

And it worked very well. You can use the following voice commands.

You can assign symbols to the individual rooms. These do not only contribute to a better overview.

The individual room symbols also play a vital role in voice control.

With this, you can also send the OZMO T8 to a specific room by voice control.

We also use this function very regularly. Very nice feature!

The volume of the Ecovacs Deebot OZMO T8+ depends on the selected suction mode:

• Quiet: 45 dB

• Standard: 50 dB

• Maximum: 55 dB

• Maximum+: 61 dB

It’s quite simple: the higher the suction level, the louder the operation.

In everyday use, we were very positively surprised by the quiet operation of the Ecovacs Deebot OZMO T8.

Especially in the "Standard" suction mode, the robot vacuum was very quiet. You won’t have any problems watching a movie or having a conversation in the same room (at a slightly higher volume).

The emptying station, on the other hand, is extremely loud.

But the emptying process only takes about 20 seconds, so it wasn’t a big deal to us.

If you live in a rented flat, we wouldn’t recommend using the emptying station at night. Only if you want to annoy your neighbour ;)

But, the OZMO-Pro "vibrating wiping function" is also pretty noisy. However, we didn’t find it unpleasant or disturbing.

The scope of delivery of the Ecovacs Deebot OZMO T8+ is enormous.

• Deebot OZMO T8+

• 2 x side brushes

• 2 x replacement side brushes

• Charging station with power supply

• 1 x HEPA filter

• 1 spare HEPA filter

• Fake water tank (dummy) to attach (looks better)

• OZMO Pro water tank

• Instructions manual

• 22 x wipes (disposable)

• 2x vacuum bag

• 1x vacuum cleaner station

• 1 x cleaning tool

• Automatic Emptying station with 2 dust bags

Ecovacs UK provides a lot of spare parts and accessories in the scope of delivery. If you need certain spare parts, you can always order them online.

You can also buy the vacuum bags for the emptying station online at Amazon UK (here*).

We’ve had one issue with the scope of delivery:

There was no reusable wipe for the wiping function. The disposable mops are impractical, and they do neither good for the environment nor your wallet.

Unfortunately, there is currently no reusable wipe for the OZMO-Pro water tank.

However, as we described in the previous chapter ("Mop review"), you can also use the reusable wipe from the previous model (OZMO 950).

It’s got significantly better quality than the disposable wipes and also achieves a better cleaning result.

The Ecovacs Deebot OZMO T8 Plus had three highlights in our review:

• The mopping function with "scrubbing effect" improves the cleaning result of stubborn stains.

• The self-emptying station automatically empties the mobile dust container (time-saving and great for allergy sufferers as there is no contact with the dust).

• The TrueDetect 3D obstacle detection makes sure that it identifies even smaller objects as obstacles and are automatically avoids them (very useful in more "chaotic" households).

It’s also worth to take a look at the price of the Deebot OZMO T8 Plus.

It’s a luxurious vacuum cleaner, and it’s certainly not for bargain hunters.

Another option would be the Deebot OZMO 950 (predecessor model). This is also an excellent vacuum-mopping robot. It just doesn’t have all the luxury features of the T8+ (but it’s available at a lower price).

You don’t have a problem with digging a little deeper into your pockets and want one of the most innovative and best vacuum-mopping robots on the market? Then the Ecovacs Deebot OZMO T8+ is just the right model for you.
