The DEEBOT T80 Omni brings more than double the suction, a roller mop that scrubs with real pressure, and nearly five hours of runtime, making it the stronger pick for homes with pets, carpet, and floors that get genuinely dirty. The Mova S20 Ultra counters with a dock that holds more water and adds detergent automatically, plus mapping for up to four floors. Buyers who want the deepest clean should go with the Ecovacs; those who want solid all-around cleaning for less and live in a taller home will be happy with the Mova.
One of these robots cleans floors with a spinning roller mop pressing down at 6 N. The other drags a vibrating pad at 3.5 N. That single design choice sets the tone for the whole matchup between the Ecovacs DEEBOT T80 Omni and the Mova S20 Ultra. Both run LiDAR plus camera navigation, both empty themselves, and both wash and handle their own mops. But the Ecovacs pushes harder on cleaning hardware across the board, and the Mova answers with a roomier dock and a lower asking price. Here's how that trade-off actually plays out day to day.
Ecovacs DEEBOT T80 Omni
out of 10Mova S20 Ultra
The Ecovacs DEEBOT T80 Omni takes this one with an 8.2 overall rating against 7.3 for the Mova S20 Ultra. Cleaning is where the gap opens up: 8.6 versus 7.2, which means the T80 Omni pulls more dirt out of carpet and leaves cleaner floors on a single pass. It also edges ahead on features, 6.5 to 5.6, so you get more useful extras day to day. Navigation is a tie at 8.1 each, so both get around your home without drama. The T80 Omni delivers more than you pay for, and the Mova is still solid for what it costs.
Suction is the headline: 18,000 Pa on the Ecovacs against 8,300 Pa on the Mova, and that gap shows on carpet and in floor edges. Mopping splits along technology lines too. The T80 uses a roller mop, the newest approach on the market, applying 6 N of pressure and washing itself with 167 °F water, whereas the S20 Ultra relies on a vibrating pad buzzing at 4,050 vibrations per minute with 3.5 N of pressure and 140 °F wash water. Runtime favors the Ecovacs at 297 minutes to 210. Flip the script at the dock, though: the Mova holds more clean and dirty water, and it adds detergent automatically when washing the pad. It also maps up to four levels versus two.
18,000 Pa versus 8,300 Pa is a wide gap, and the Ecovacs backs it up with anti-tangle hardware on its rubber-and-bristle brush. The Mova's dual rubber brushes and larger onboard dustbin are genuine strengths, but they don't close the distance on deep carpet pickup.
The T80's roller mop is the more capable system here, scrubbing with 6 N of pressure and washing in 167 °F water, plus it extends to reach edges. The S20 Ultra's vibrating pad runs at 4,050 vibrations per minute with 3.5 N of pressure, which handles light spills fine but doesn't scrub dried messes the same way.
Anti-tangle on the Ecovacs matters more than anything else if you own a shedding dog, since long hair wrapping the brush roll is the number one maintenance headache. Pair that with 18,000 Pa and the T80 is the clear pet-home choice, even though the Mova's dust bag holds slightly more.
Both use LiDAR, a camera, and 3D structured light for obstacle avoidance, and they rate within a hair of each other. The Mova adds an LED to help its camera see in dim rooms and stores maps for up to four levels versus two on the Ecovacs, which is what tips this category.
The Mova's dock carries more clean water and holds more dirty water, so it goes longer between refills, and it dispenses detergent automatically for cleaner mop pads. The Ecovacs counters with hotter mop washing at 167 °F and hot air drying at 113 °F, which keeps the mop from smelling musty.
297 minutes versus 210 gives the Ecovacs roughly an extra hour and a half of cleaning per charge, backed by a 6,400 mAh pack against 5,200 mAh. It also supports off-peak charging, so it can top up when electricity rates drop.
Both work with Alexa and Google, and both offer no-go zones, multi-level maps, smart carpet cleaning, and smart obstacle avoidance. The Ecovacs adds built-in voice control so you can bark commands at the robot directly without a smart speaker in the room.

If cleaning results are what you're paying for, the DEEBOT T80 Omni wins on suction, mop design, anti-tangle, and runtime. The Mova S20 Ultra is the smarter buy when the budget is tight, your floors are mostly hard surface, or you need maps for more than two levels.
