For a brand that made robot vacuums accessible, my faith in Ecovacs is shaken after using the Deebot T90 Pro Omni | Daily Reports Online
I’ve reviewed a few robot vacuums in the last year sister site Tom’s Guide, but I’d yet to try one from powerhouse brand Ecovacs Robotics. With several excellent reviews already on TechRadar, including those by my colleague Sharmishta, who swears by the brand and rated the Ecovacs Deebot X8 Pro Omni very highly, I was eager to get stuck into my own assessment of the Deebot T90 Pro Omni, which launched in March this year.
On paper, it came across as the perfect pet-friendly robot vacuum. It touted an impressive 30,000Pa suction power across hardwood and carpeted floors, and as a mum to two Border Collies, cleaning up fur every day was my #1 priority.
It also didn’t help that I fell pretty hard for The T90’s looks (more on that below), but I was anxious about its price — $899.99 / £899 / AU$2,299 seemed rather steep, especially in Australia where I’m based, for a T-series Deebot that’s typically been the more mid-range option to Ecovacs’ X-series flagships. But then you get what you pay for, right? Or so I thought.
After using it for three months, I was left with an expensive robot vacuum that still looks lovely in its corner but doesn’t quite fulfil the rest of its promises.
It’s a looker
If you’ve often considered a robot vacuum, but have been put off by the large, rather unsightly docking stations, then you’ll be pleased to learn that the Deebot T90 Pro arrives with the newly enhanced Ecovacs station. The dock and station’s combined footprint is slim, and it can easily be placed under a counter or table if you want to store it away. But given its Nordic-inspired, fabric-like design, Ecovacs clearly didn’t intend for the T90 to be hidden, especially in homes with minimalist aesthetic settings. Personally, I quite liked the new off-white color as it complemented my apartment decor.

Unlike some other Ecovacs’ robot vacuums, the T90 Pro Omni’s bot neglects a turret completely, opting for a LiDAR sensor at the front of the machine, so it can get under furniture without issues. In place of a turret sits a loosely placed fabric-like lid that can, sadly, get dislodged when bumped into with some force.
However, the fact that both water tanks are fully concealed within the dock is a big tick for me, as it means I never once had to catch sight of dirty water throughout the day. The trade-off to this is that you can’t see if either tank is full or empty. If you set the robot vacuum to clean everyday, then you’ll need to regularly check the tanks to see if they need filling or emptying.
I found I was consistently emptying and refilling the water tanks after every other clean despite its 4L capacity and the mopping area in my apartment is the living, dining and kitchen (my bedrooms are carpeted). I’m also a little surprised that the dirty-water capacity is so much lower, I was expecting it to be around 3L. What that means is, if you live in a large family home, you’ll likely need to clean out the dirty mop water between each session too — beats the purpose I think.
Looks can be deceiving
It’s lovely design aside, the T90 Pro struggled from day one, starting with its initial floor mapping. As I’ve already mentioned, my single-storey apartment has a mixture of carpeted and hardwood floors and a relatively straightforward floor plan, which most robovacs I’ve tried can get right the first time. Nevertheless, it took six mapping sessions to finally achieve an accurate map of my home.
I’ll take some of the blame here, as the one map error was my fault after leaving my built-in wardrobe open, but I wanted to believe that after considerable daily use, the bot would update the floorplan on its own — I suppose I was expecting too much from Ecovacs’ software there.
Even after the T90 had mapped my home accurately, I still had to make significant edits in the app to get all the rooms marked out correctly, something I’ve not had to do with other brands.
I made sure all carpet areas were marked out and, despite that, the T90 Pro Omni repeatedly mopped the bedrooms when in Auto mode to do a full-house clean. The only way to avoid this was to start setting up Room or Zone cleans every single time. In other words, the Auto Mode, for me, was redundant.
Aside from the copious amounts of remapping and wrong floor recognition, the T90 faltered when it came to vacuuming up pet hair. Despite its high suction power, I found that the T90 consistently left pet hair on even my hard floors (struggling even more on carpets), and I had to do a follow-up clean with my Dreame U20 which, even as affordable cordless option without a lot of suction, does so much better.
This really was my biggest disappointment because Ecovacs’ Blast suction promises improved airflow for the best clean and I saw no evidence of that here. Moreover, a lot of the pet hair got entangled in the central bar brush and its wheels, meaning the bot itself required constant maintenance.

Mopping was a rather unfortunate experience too, especially after all those trips to and from the tap. My wood floors were left streaky and some spills were ignored by the AI stain recognition. My colleague Sharm much prefers the roller mops to the rotating discs on robovacs, but I’m not convinced… yet.
Random starts was another issue I had to face with the T90 Pro Omni — it would just start cleaning on its own, even when there was no voice command or a schedule set up.
There was a silver lining in all this, though: despite being a little basic compared to other robot vacuum apps I’ve used, the Ecovacs Home app was fairly easy to use (after the remapping shenanigans of course) to set up custom cleaning routines, schedules, suction and waterflow rates.
The easy-to-use app doesn’t make up for everything else that went wrong though.
So, what now?
Look, I’ll be honest — I was hard-pressed to find something positive to say about the Ecovacs Deebot T90 Pro Omni. A nice design and a decent app will only take my over user experience so far.
I wasn’t looking for perfection; I just needed a robot vacuum that do the daily cleanup so I didn’t have to and, in that one task, the T90 failed as I had to vacuum again anyway.
And this isn’t the first time a Deebot has disappointed — my colleague Sharm wasn’t particularly enthused by the older Ecovacs Deebot T50 Max Pro Omni either. TechRadar’s recently published Ecovacs Deebot X12 Omnicyclone review also doesn’t look very encouraging.
So what’s going on at Ecovacs Robotics, one of the pioneering robovac brands? The company’s been pumping out new models in quick succession over the last few years, with three alone announced at CES 2026, but it just feels like software and performance issues aren’t being fully tested before release to market. Maybe it’s time for Ecovacs to slow down, take a beat, and perhaps learn from its mistakes before releasing another suite of subpar products.
I’m still keeping faith that the brand will impress me one day, it’s just not going to be with the T90 Pro Omni.
