1. Design & Physical Profile

The Dreame X40 Ultra comes with a modern design and a standard-sized build. Its biggest design highlight is the SideReach extendable side brush, which extends outward to sweep along walls, corners, and around furniture legs where most robots struggle. It also has a liftable mop system that automatically raises when carpets are detected, reducing the risk of wetting rugs.

On the other hand, the ECOVACS Deebot T50 PRO is one of the slimmest flagship robots available, standing just 8.1 cm tall. This ultra-thin profile allows it to glide under low sofas, beds, and cabinets with ease. While it doesn’t have a retractable brush like the Dreame, its slimness gives it an advantage in reaching areas where taller robots simply cannot go.

Verdict: T50 PRO wins for compactness, while X40 Ultra scores for flexibility in edge and carpet handling.

2. Suction Power & Cleaning Strength

The Dreame X40 Ultra offers 12,000 Pa suction, which is already very powerful compared to most high-end robot vacuums. It uses optimized airflow channels to maintain strong suction and avoid blockages, making it effective for deep cleaning across tiles, wood floors, and carpets.

The ECOVACS Deebot T50 PRO, however, raises the bar with an industry-leading 15,000 Pa cyclonic suction. This makes it particularly strong at lifting embedded dust, pet hair, and debris from thicker carpets. In raw numbers, the T50 PRO has a clear edge, though in practical use the difference may be most noticeable in homes with lots of carpets or pets.

Verdict: T50 PRO is stronger in suction.

3. Mopping & Self-Maintenance

The Dreame X40 Ultra uses a removable and liftable mop system, capable of lifting up to 10.5 mm when it detects carpets. Its docking station sanitizes the mop pads with 158°F (70°C) hot water, ensuring hygiene by removing stains and odor. You can even set different temperature levels through the app for more customized cleaning.

The ECOVACS T50 PRO also features advanced mopping, with 75°C hot water mop washing, automatic drying at 45°C, and an intelligent dirt-detection system that ensures mops are cleaned when required. It also has TrueEdge 2.0, which extends the mop by 15 mm to reach into wall edges and corners.

Verdict: T50 PRO wins for a more complete hands-free maintenance system, while Dreame leads in ultra-hygienic hot mop cleaning.

4. Navigation & Obstacle Avoidance

The Dreame X40 Ultra combines 3D structured light, a built-in camera, and LED sensors to map rooms and navigate even in dim lighting. It also features OmniDirt detection to identify tough stains and adjust scrubbing patterns, plus MopExtend RoboSwing for targeted cleaning in tricky spots.

The ECOVACS T50 PRO comes equipped with AIVI 3.0 obstacle avoidance, an AI-powered system that recognizes over 100 household objects with millimeter-level precision. This means it can avoid toys, shoes, socks, and cables with fewer mistakes, making it especially useful in busy homes with kids or pets.

Verdict: T50 PRO is more advanced in obstacle recognition, though Dreame performs very well in controlled environments.

5. Battery Life & Coverage

The Dreame X40 Ultra has a 6,400 mAh battery that provides up to 198 minutes of runtime, enough to cover most medium to large homes in a single charge. If the battery runs low, it recharges automatically and resumes cleaning.

The ECOVACS T50 PRO also carries a 6,400 mAh battery, but offers a longer runtime of 250 to 320 minutes depending on mode. This extended coverage makes it ideal for very large homes or multi-room apartments without frequent recharging interruptions.

Verdict: T50 PRO clearly wins for runtime and coverage.

6. Edge & Corner Cleaning

Dreame has an advantage here thanks to its SideReach extendable side brush and MopExtend RoboSwing technology. These allow the robot to physically extend into corners and sweep dirt from hard-to-reach edges.

The ECOVACS T50 PRO uses TrueEdge 2.0, which extends its brush and mop by 15 mm, giving it strong corner coverage as well. While effective, it is not as mechanically aggressive as Dreame’s extendable brush design.

Verdict: Dreame X40 Ultra has the edge (literally) in corner cleaning.

7. Smart Features & App Control

The Dreame X40 Ultra app provides custom cleaning modes, adjustable mop water temperature, no-go zones, and multi-floor mapping. It also allows users to customize mopping intensity and cleaning strategies for different rooms.

The ECOVACS T50 PRO takes smart features a step further with its YIKO-GPT intelligent assistant, which understands natural voice commands. You can speak to the robot directly, and it can carry out tasks or answer queries, making it far more interactive. Along with that, it offers ZeroTangle 2.0 for hassle-free pet hair cleaning.

Verdict: T50 PRO wins for its smart voice assistant and AI-powered customization.

8. After-Sales Support

The Dreame X40 Ultra comes with a 1-year warranty, which is standard in this segment. While it is reliable, after-sales support depends on third-party service networks in India.

The ECOVACS T50 PRO, in contrast, has a much stronger service presence in India, with free installation, doorstep service, and over 90 service offices nationwide. This makes it a safer choice for long-term use if you value quick and reliable service.

Verdict: T50 PRO is far ahead in after-sales support, especially in India.
