The Deebot T9 features what they call “TrueMapping” which is a combination of Lidar and a DToF laser sensor to give it one of the most robust and efficient navigation programs of any robot vacuum in our test.
It completed our room mapping test faster than any other vacuum in our test, and it follows a logical pattern as it moves around the perimeter and then efficiently cleans open spaces. It is able to recognize carpets and rugs and change the cleaning mode accordingly. However, it did get confused by our black-colored carpet and seemed to be uncertain how to proceed.
It has excellent obstacle recognition and is able to cleanly navigate around furniture and even cords and pet waste. With that said, it did not completely avoid our fake pet waste, so we would recommend checking before you start cleaning.
We scored the Deebot a 5 out of 5 for navigation, and you can trust that it will recognize most obstacles while efficiently managing just about any type of room.
The Deebot T9 also does a great job of cleaning. It has the highest rated power in our test at 3000Pa, and we saw the results of this power in our tests. It also has 2 spinning side brushes that help to pick up debris that other vacuums might miss.
In both the hard surface and carpet tests, the Deebot performed very well. It was able to pick up both smaller bits of debris and larger debris easily. In addition, it performed the best in our pet hair test leaving behind only traces of fur.
The T9 also has a mopping feature, but this is not very well implemented. One drawback is that the mop pads are disposable, which means you will need to buy new ones again and again. We prefer washable pads that are reusable. It also struggled to eliminate stains in our test leaving behind sticky residue and coffee even after several passes.
Even though the mopping was subpar, it still had excellent overall cleaning results, so the Deebot earned a 4.5/5 in our cleaning performance category.
Like most of the top robot vacuums we tested, the Deebot is a smart vacuum which means it comes with its own app that allows you to customize many features. We found the app simple and easy to install and using the QR code that came with the vacuum made set up takes only seconds.
The app includes a good smart mapping feature that is visually appealing, and you can set “no go” zones to keep the vacuum from going places you don’t want it to such as under a cluttered work desk or near the cat litter box.
You can schedule cleanings as well as adjust both the suction power and mop water usage.
There is also a screen that lets you see the maintenance schedule showing you what percentage of use you have left in your brushes, filters, and other components. The vacuum comes with an air freshener feature that can be controlled via the app, but we felt this was more of a gimmick than a useful addition.
While the app is not difficult to use, it is not as intuitive as it could be, and it did take some time to learn how to navigate it efficiently. Because of this, we rated it a 4.5/5
Ease of use
When it comes to ease of use, the Ecovacs Deebot T9 is a top performer. Our model came with an optional auto-empty station along with a dock, and this made emptying the dustbin easy, but even manually emptying the 420ml dustbin by hand is a simple task.
With parts regularly available and the maintenance reminders in the app, remembering to replace the brushes or filter is a simple task.
When working, it was among the quietest vacuums averaging around 63dB and reaching 74 at its peak. This is about the same as a normal conversation or traffic from inside of your car.
Operating the Deebot is quite simple and since it navigates so well, you can let it go about its business. It has a long battery life, and if it does run low, it will automatically dock, recharge, and then continue cleaning where it left off. It also performed well in our threshold test, able to clear 2 centimeters with ease.
We gave it a score of 4.5 out of 5 in this category.
With an overall score of 4.7/5, the Deebot T9 was at the top of our list for overall best robot vacuum. We think it does a terrific job both navigating and cleaning with top-of-the-line object recognition. It is easy to use and maintain, so if you want one of the best robot vacuums that you can rely on time and time again, this is an excellent choice.
