Deebot T20 vs. T30 – Comparison Review

Deebot T20 is a white round robot with a grey top cover and TrueMapping Distance sensor (detection range 10 m) with a microphone on top. There are plenty of sensors on the robot in different locations: In front – TrueDetect 3D sensor (detection is 0.35m); on both sides – are anti-collusion and anti-drop sensors, and on the bottom are ultrasonic sensors (for carpet detection).

The robot is protected from accidental crashes with a bumper in front. On the lid is one auto mode button, under the lid is a power switch button and a reset button to restore to default settings. On the back side, there are two charging contacts at the docking station.

The robot is slim – about 4 inches – to go under the furniture. For moving, it uses two driving rubber wheels around a floating brush.

T20 can be cleaned in auto, custom, manual, and spot modes. In all these modes, the robot can perform vacuum and mop functions separately or simultaneously.

The robot automatically detects carpets and increases suction power accordingly for maximum suction. In the standard mode, the noise level is up to 69 dBa in sweep and mop mode, which I consider a reasonable level.

Deebot T20 for mopping is equipped with two rotating pad plates (180 RPM and 6N download pressure) on which two washable mopping pads are assembled. It cleans using OZMO Turbo 2.0 technology. The internal water tank size is 80 ml, and it has 3 level water levels for manual and automatic adjustment.

The mop dimension is 123 cm2, and the maximum mopping area is 400 m2. I checked that with a mopping pad; the robot can cross the barriers up to 0.79”. On carpets, the mopping pads are lifted automatically at 0.35”.

Deebot T20 has a powerful suction power of 6000 Pa to suck all dust and debris from carpets, tiles, and hard and wooden floors.

Deebot T20 uses multiple sensors and LIDAR navigation, structured light technology, 3D map algorithms, and 3D scanning technology to efficiently clean all types of floors and avoid obstacles and hazards.

The detection technology is four times higher than with previous technologies. The robot quickly builds precise 3D maps for further customization in the smartphone app and sets no-go zones and virtual walls.

T20 robot is equipped in a dustbin with a washable antibacterial high efficiency filter (5.12 inches in length) and is categorized as E11. The inlet of a dustbox is also protected with a net before the filter. The filter can capture up to 99.99% of dust particles, pollen, and other substances. I like the filter, which is made from eco-friendly materials.

Deebot T20 has two side brushes with plastic bristles to reach all edges and corners and one main floating all-rubber high-quality brush.

The brush has tangle detection to effectively collect pet hair and reduce hair tangling. I can easily clean brushes with a cleaning brush.

T20 robot has two tanks—a dustbin with a filter and dust bag handle and a three-level water adjustment.

After I remove the lid, the tanks are accessible from the top. The water tank has a low water level alert.

T20 has a high-quality 14,4М Li-ion battery with a long service life. It is protected from short-circuits, over-voltage, over-hear, and over-current. The robot is compatible only with authorized batteries from authorized dealers.

I prove that on the low battery level, the robot goes automatically to the docking station for charging and resumes at the same spot where it has stopped. The full charging time is 6.5 hours. The working time in vacuum and mop mode is 170 minutes on a single charge; in vacuum-only mode, it achieves even 260 minutes.

Apart from the charging function, T20 docking station offers many other features for automatic regular maintenance. It washes mopping pads and dries them with hot air for 2 hours (a default time), collects dust from a dustbin in 10 seconds into a 3L dust bag, keeps dust for weeks (up to 75 days), and cleans the station from one press of a button.

The noise collection noise is about 81 dBA, but you can schedule the dust emptying time in your app. For cleaning mopping pads, hot water at a temperature of 131 F is used to dissolve dirt, and oil is used after that is rapidly dried with hot air to prevent odor.

The clean water for self-cleaning and mopping pad cleaning is stored in a 4L clean water tank; the dirty water is collected in a 4 L tank.

Deebot T20 is controlled not only by one auto button on the body but also using the ECOVACS smartphone app and voice assistant, including its own YIKO assistant, which understands natural language commands.

You can customize cleaning in the app or use voice control by choosing the required room, area, or cleaning mode. In the app, I can also correct the 3D map, check status, set schedules, identify no-go zones and virtual boundaries, and more.
