In August 2019, Xiaomi released the newest robot vacuum - Xiaomi Mijia STYJ02YM. It is the first model in the family that can do both: mopping and sweeping.

Design & Navigation

The Xiaomi Mijia STYJ02YM has the same design as its older brother, the Xiaomi Mi Robot.

With the LDS laser on top, the robot scans the surroundings to create a map of the cleaning area so the robot knows where it should clean. Mapping helps the vacuum to cover the whole area without having it cleaning the same areas twice or leave some areas untouched.

When the vacuum is working, it follows a back-and-forth navigation pattern.

The cleaner is equipped with 12 high-precious sensors that help it navigate around without falling off, bumping into furniture, or just be more careful when operating.

When it finishes cleaning, it creates a map which can be divided, merged, and has the ability to name each room. This feature is very helpful if you don't need to clean the whole house. Just set the robot to go directly to the kitchen/bedroom and let it work.

The most significant improvement over the previous models - mopping feature. The Xiaomi Mijia STYJ02YM can mop, sweep, mop and sweep at the same time. Neither the Xiaomi Mi Robot or Xiaomi MiJia 1S Robot Vacuum can mop.

Mopping mode

The Xiaomi is equipped with two containers, the one (550 ml) for sweeping (dust container), the other container (550 ml) is 2-in-1 for mopping and sweeping. The second container can be used if you want the robot to mop and sweep. The previous models have a 420 ml dust container, by the way.

If you need the Xiaomi to mop only, the 550 ml water container can be bought separately.

We are not sure if you can make the robot only mop with the included container, though it can do both at a time.

The two in one container can be half-filled with water for mopping, the second half of the tank is for dust the robot sucks up when working.

In mopping mode, the Xiaomi follows a Y-shape (two-way repeated wiping) path. It helps to provide better mopping performance since the robot doesn't just drag the mop but returns to the same spot twice for better results.

There is not much information about the model. The manufacturer says it has three level water settings, which means you can set the level of water dripping depending on your needs. Unfortunately, we are not sure, either you can change the settings in the app or directly on the water tank.

There are two types of mopping pads in the box included: wet mop and a half wet mop. Insert the 2-in-1 water container, attach the mop stand with a pad you need and let the robot work.

We should say, the Xiaomi Mijia STYJ02YM is not suitable to remove stubborn stains, but it is a better solution than most hybrid models that just drag the pad. The robot is suitable for everyday mopping and will prolong the time between actual manual mopping sessions.

Mi Home & Smart Features

The Mi Home app has many options such as tracking the robot in real-time, manually control its movements, switch between cleaning modes, track when the accessories need to be replaced, etc.

The smartest features would be zoned cleaning, restricted areas, and room cleaning.

If you want the robot to not go to certain places, you can set blocked zones, and the robot won't cross them. Useful if you need to prevent carpets from getting wet when the robot is mopping, or some areas might be cluttered, etc.

Zoned cleaning is great for spot cleaning. If you have high-traffic areas or places that are dirtier than others, you can make the robot work there by drawing a rectangle on the created map.

Make the Xiaomi work directly in the kitchen by using the room cleaning feature

Room cleaning is our favorite feature. Since you can divide the map into separated rooms, the robot can be ordered to go to the kitchen or living room if needed. If you don't need to clean some rooms such as a guest room, you can either use blocked areas or simply choose other rooms to clean.

Battery life

The Xiaomi Mijia STYJ02YM has a smaller battery size of 3,200 mAh than its brothers Mi Robot and MiJia 1S which have 5,200 mAh.

The robot is ideal for big homes

Predictable, the newest MiJia lasts less, up to 110 minutes other than 150 minutes the siblings do.

Since the Xiaomi resumes cleaning in case it does not finish the job before the battery dies, the robot is suitable for big homes. When the battery runs lower than 20%, it returns to the dock, recharges up to 80% and finishes cleaning from the same spot it left off.

Suction Power

The newest model has the strongest suction among the Xiaomi cleaners delivering 2,100 Pa of suction. The older models have 1,800 (Mi Robot) and 2,000 Pa (MiJia 1S).

Stronger suction helps a lot when you need deeper cleaning on carpet.

Climbing Ability

Crossing ability seems to be increased too. From 0.59 / 15 mm (Mi Robot) to 0.79 in / 20 mm (Mijia STYJ02YM).

It matters if you have taller thresholds or thicker carpets. The Mi Robot has issues with thick carpets, the newest model promised to be better at this.

Filtration System

Since there's not much information, we are not sure if the robot is equipped with a filter that can be washed with water. However, we know that the Xiaomi Mijia STYJ02YM is equipped with a HEPA filter and is safe for everyone who suffers from an allergy or asthma.

Price & Where to buy

The Xiaomi Mijia STYJ02YM so far is only available on Gearbest where you can get it for ~$530.
