Ecovacs Deebot T90 Pro Omni 90-Day Review: Big Mop Upgrade, Mixed Carpet Performance
After more than 90 days of testing, the Ecovacs Deebot T90 Pro Omni has become our pick of the company’s current lineup, thanks to strong hard-floor cleaning, a much wider roller mop and pricing that often undercuts more expensive models.
This unit was purchased for personal use, and this review is not sponsored, approved or otherwise affiliated with Ecovacs.
Ecovacs released the Deebot T90 Pro Omni in North America earlier this year, a mid-tier successor to last year's T80 Pro Omni that brings several flagship features to a much more affordable price.
The T90 Pro features 30,000 pascals of suction, a redesigned full-length Ozmo Roller 3.0 mop, an embedded time-of-flight sensor, Aivi 3D 4.0 obstacle avoidance and PowerBoost charging.
After more than 90 days of testing, the T90 Pro has become our pick of Ecovacs' current lineup. It isn't perfect, particularly on thick carpet, but it offers an impressive amount of value for the money.
What's Included
The standard package includes the T90 Pro robot, Omni base station, clean and dirty water tanks, power cord, side brush, main brush, dust filter, dust bag, microfiber mop roller and 8.8 fluid ounces of Ecovacs cleaning solution.
Ecovacs also includes a user manual and quick-start guide.
There aren't many spare consumables in the box with the basic SKU, replacement dust bags, filters and brushes will need to be purchased separately.
Premium on the Outside, Less So Inside
At first glance, both the robot and its all-in-one base station feel premium.
The charcoal station features a textured facade with gold accents that carry over to the robot.
At 3.74 inches tall, the T90 Pro has a sleek, low-profile design that skips the traditional raised lidar turret allowing it to reach under more furniture.
Some of that premium feel fades on closer inspection. The water tanks, dustbin and filter assembly use thinner plastics that feel cheaper than the exterior suggests.
The gold-painted trim on our unit wasn't applied evenly, and the clean and dirty water tanks are also fingerprint magnets.
The contrasting white color of the removable cleaning tray also looks odd against the charcoal base station, though the tray itself is sturdy and easy to remove.
A Huge Mop Roller Improvement
The new Ozmo Roller 3.0 measures 10.63 inches across, roughly 50% longer than the previous version. Ecovacs says it spins at up to 200 rpm and applies up to 3,700 Pa of mopping pressure.
That extra width makes a bigger difference than it might sound.
Earlier Ecovacs models used a much shorter mop roller with a relatively narrow cleaning path, which added considerable time to each run.
The T90 Pro fixes that with a full-width roller that covers considerably more floor in each pass. Fresh water is continuously applied to the roller while dirty water and debris are scraped away.
On our dark hardwood floors, it also avoided the streaking we've seen from some other lower-cost mop roller models.
The Ecovacs app lets you identify different floor types on the map, and the T90 Pro will adjust water saturation accordingly.
That was particularly useful on our engineered wood flooring, where it kept the roller damp enough to clean without leaving the surface overly saturated.
You can also set the direction of wood plank flooring on the map, allowing the robot to clean along the grain rather than cutting across it.
Water coverage across the roller was consistent, and even on tile, which uses much more water, it wasn't dripping as it moved around.
The roller can also extend toward walls and furniture, though the extension can become a little aggressive depending on the setting.
A felt-covered edge helps protect walls, cabinets and trim when the roller extends. The T90 Pro is one of the few robots we've tested that hasn't left scratches or scuff marks on our white toe kicks or quarter-round trim.
The felt collects lint and dirt quickly, but it's durable and has done its job throughout our testing without becoming dislodged or peeling off.
Another advantage is that the T90 Pro doesn't use a removable onboard dirty water reservoir like some competing roller-mop robots.
Instead, dirty water is routed into an inaccessible internal reservoir, while a small propeller system helps keep water moving. The base station flushes the system with fresh water.
This eliminates another small tank that would otherwise need to be removed and cleaned by hand.
There's no protective cover over the mop roller when traveling across carpet, and the T90 Pro doesn't lift its chassis on rugs. That makes it less appealing for homes dominated by thick carpet.
For hard floors, however, the new roller is a major improvement and easily one of the strongest parts of the T90 Pro.
Overall, the roller-mopping experience was on par with other more expensive competing mop roller models we've tested.
Vacuuming Is a Mixed Bag
Ecovacs' new main brush looks remarkably similar in concept to the main brush Narwal has used for several years.
The T90 Pro's main brush is supported primarily from one side, giving hair a path to work its way off instead of wrapping around an axle. Ecovacs adds directed airflow to further reduce tangles.
It works well for hair, but there's a trade-off.
Pickup on our thicker carpet is poorer than we'd expect from a robot advertising 30,000 Pa of suction. The main brush simply doesn't dig as aggressively into thicker carpet as previous Ecovacs brush designs.
The side brush also doesn't extend for edge cleaning, leaving the T90 Pro without the corner-cleaning ability offered by some competing models.
Navigation Gets Better With Time
Our initial mapping experience was mediocre.
The first map needed work and didn't inspire much confidence, but subsequent cleaning runs continued refining the layout. After several runs, the map became considerably more accurate.
That improvement has held up over roughly 90 days of use.
Room editing and dividing are also more forgiving than on some competing platforms, making it easier to refine the map after two or three cleaning runs.
The T90 Pro's auxiliary wheel system helps it clear minor transitions, but threshold climbing is average at best.
Obstacle avoidance is above average for a mid-tier robot vacuum.
The T90 Pro recognizes most common objects, Ecovacs refuses to say how many exactly like other brands, but the robot still has a tendency to bump into furniture and get tangled in cords.
Its obstacle avoidance also becomes less reliable on carpet.
The App
The Ecovacs app has improved significantly over the past 24 months, but it can still be confusing.
There are a lot of features, settings and submenus, and it isn't always obvious where a particular option lives.
Agent Mode is a good example. The feature can automatically determine how rooms should be cleaned based on the home, flooring and previous runs. It's genuinely helpful once configured, but getting everything set up properly can be tedious.
Anyone expecting to simply turn it on and forget about it may be surprised by how much initial configuration is involved.
The Yiko voice assistant is much easier to appreciate. Ecovacs has one of the best onboard voice assistants currently available on a robot vacuum. It can understand more than a short list of rigid commands, making it possible to give commands naturally instead of memorizing exactly what the manufacturer expects you to say.
The T90 Pro also supports Matter for integration with compatible smart home platforms.
PowerBoost Takes Some Getting Used To
The T90 Pro uses a relatively small 4,000 mAh battery, but PowerBoost charging changes how it approaches larger cleaning jobs.
Initially, the behavior can be confusing. The robot may return to charge at times that seem unnecessary or leave the dock before reaching the charge level you might expect.
It gets better.
As the T90 Pro learns the size and cleaning requirements of your home, it begins adjusting when and how long it charges.
Much like the mapping system, PowerBoost makes more sense after several complete cleaning cycles than it does on the first day.
After 90 days, battery life remains better than average for a mid-tier robot vacuum. Once optimized, PowerBoost charging makes the T90 Pro feel like it has a larger battery than it actually does by topping it up during longer cleaning runs.
Maintenance
The T90 Pro is fairly easy to maintain, though a few areas require more attention than others.
The washable air filter is particularly small. Even with a pre-filter catching larger debris, ours becomes clogged with fine dust relatively quickly. We'd plan on checking and cleaning it at least weekly, especially in homes with pets or a lot of dust.
The main brush should also be checked weekly. The brush area tended to collect some dirt buildup while using the vacuuming and mopping feature.
The built-in scraper does a good job removing hair and debris from the brush, but it still needs occasional inspection and cleaning. In homes with pets, we'd plan on checking it weekly or every other week.
The side brush was more troublesome. Ours had a tendency to catch on objects and tear off during cleaning. Owners may want to keep a few replacements on hand, and inexpensive third-party multipacks are available.
Ecovacs says the disposable dust bag can last up to 90 days, though actual replacement intervals will depend on how much debris the robot collects.
The Omni base station did a good job taking care of the mop roller during testing. It washes the roller with water heated to as high as 167 degrees and dries it with 145-degree hot air.
The mop roller dried adequately, and we never noticed the mildew or sour smell that can develop on some roller-mop systems.
The removable washboard tray also stayed relatively clean. We found that cleaning it once a month was sufficient, and being able to lift the entire tray out of the station makes the job much easier.
The included detergent had a pleasant scent and lasted through our entire review period.
Replacement parts are one area where Ecovacs could do better. First-party filters, dust bags, brushes and other accessories can be harder to find on retail outlets like Amazon compared with other brands.
Ecovacs regularly discounts accessories on its official website, so wait for a sale before stocking up.
Strong Value, With Trade-Offs
After more than 90 days, the Deebot T90 Pro is currently the Ecovacs robot we'd buy.
It carries a $799.99 MSRP but typically sells for around $599.99, putting it toward the lower end of the mid-tier market.
Ecovacs' Trade-Up program can make it considerably cheaper. As of September 2026, we've seen the final price of the T90 Pro fall to $400 or less, depending on the promotion and trade-in value.
At those prices, some of the T90 Pro's shortcomings become much easier to overlook.
For homes with mostly hard floors and some carpet, the T90 Pro strikes a better balance than Ecovacs' more expensive models.
