Ecovacs Deebot T20 Omni vs Ecovacs Deebot T50 Max Pro Omni
Quick take: The Ecovacs Deebot T20 Omni costs $200 less; the Ecovacs Deebot T50 Max Pro Omni has stronger suction (18,500 vs 6,000 Pa); the Ecovacs Deebot T20 Omni runs longer per charge (260 vs 206 min).
Which one to buy
The Ecovacs Deebot T20 Omni is discontinued (Ecovacs' replacement is the Deebot T50 Pro Omni at $400), and the Deebot T50 Max Pro Omni costs $450, about $200 more than the T20's last price. The T50 is the successor in every way that matters for cleaning: 18,500 Pa against 6000 Pa, camera-based obstacle avoidance where the T20 has none, an 18 mm mop lift against 9mm, and TruEdge 2.0 mopping that swings out to within about 1 mm of baseboards.
T20 owners liked it as an early, affordable route into hot-water mop washing. They praise its spinning mops on hard floors and its 260-minute battery, and they valued its 2-year warranty. They also list its limits: it bumps into everything and tangles with cables, the dock grinds loudly during emptying and drying, the water is warm rather than hot, and the app drops connections.
T50 owners report flagship-level cleaning in torture tests with litter, coffee grounds and long hair, edges that are mopped, hair that barely wraps the ZeroTangle brush, and a slim turret-free body that reaches under sofas. Their complaints are software and trust: mapping failures and failed room cleans, obstacle avoidance that tests below average and misses small hazards like pet waste despite the camera, slow support, and lingering privacy worries about Ecovacs' past security incidents.
Two things favor the T20: a 2-year warranty against the T50's 1, and a longer rated runtime, 260 minutes against 206. A discontinued model also means parts and support may thin out over time. Buy the T50 Max Pro Omni, keep floors tidy, and buy from a retailer with an easy return window. Only consider a leftover T20 if the roughly $200 saving and the longer warranty matter more to you than suction and obstacle avoidance.

Ecovacs Deebot T20 Omni vs Ecovacs Deebot T50 Max Pro Omni: common questions
Is the Ecovacs Deebot T20 Omni still worth buying now that it is discontinued?▾
Rarely. The T50 Max Pro Omni costs about $200 more but adds three times the suction, camera obstacle avoidance and a higher mop lift. A discontinued model can also mean thinner parts and support later, which outweighs its 2-year warranty for most buyers.
Does the T50's camera solve the T20's habit of bumping into things?▾
Partly. The T20 has no obstacle avoidance and tangles with cables. The T50 avoids large objects, but its owners report it testing below average and missing small hazards like cables and pet waste, so pre-tidying is still needed with either.
Which one mops better?▾
The T50 Max Pro Omni. Its owners confirm TruEdge 2.0 reaches baseboards and toe-kicks, and its 18 mm lift keeps low and medium carpet dry. T20 owners like its spinning mops on hard floors, but its 9mm lift and lukewarm wash water trail the newer station.
