The built-in plant bionic tank filter absorbs the water keeping enough water content on the mop cloth. When the robot stops working, the water stops dripping. The water tank was designed for easy installation in the bottom of the device. The main brush with V-type bristles (with rotation speed of 1350 revolutions per minute) in addition to the side Z-form brushes (330 revolutions per minute rotation speed) provide the maximum effective cleaning. The water box holds around 100 ml enough to mop for 45-60 minutes. The intelligent system works by the main principle of the plant bionic system and controls the water by itself. The sliding mechanism is designed in such a way that water is spread wisely, only when the robot is moving. To empty a 500 ml dustbin, just open the lid of the robot vacuum cleaner.

The most powerful vacuum robot with a long-lasting battery

The new Xiaomi Roborock comes with a 5200 mAh Li-Ion battery, the barrier height is increased from 1.5 cm to 2 cm, the suction power is 2000 Pa, which is awe-inspiring because even the Roomba 980 designed for carpets delivers 1670 Pa. A LED battery indicator displays the charge level via different colors while the robot is charging. The white light means the battery charge level is more than 50%, yellow - less than 50%, red - the battery charge level drops below 20%.

  • Powerful motor with 2000 Pa power suction. For example, the first version Xiaomi Mi Robot Vacuum had 1800 Pa while the latest Roomba 980 delivers 1670 Pa. It deeply cleans carpets, perfect for mostly carpeted houses.
  • While other robot vacuum cleaners that are even more expensive offer about 120-130 minutes of running, the Xiaomi MiJia works the entire 150 minutes covering about 250 square meters (2700 sq. ft) of house area, providing 2000Pa of suction power. Speaking of power, it is amazing that the battery lasts for so long; it has a powerful motor that cleans carpets with ease.
  • Xiaomi MiJia Robotock easily climbs up to 2 cm high obstacles.
  • The tornado system coordinates the side and roller brushes providing deep floor cleaning.

Intelligent identification of carpets

This smart device usually works in normal suction mode, but the maximum suction mode activates once it recognizes the carpet to provide the high-quality deep cleaning.

Three tangle-free design

Tangling hair can be annoying while cleaning the main brush of other robovacs, Roborock's main and side brushes are tangle-free along with its wheels. The design helps to protect the device from overheating with the bearing stuck to the motor.

Smart Navigation Technology

Laser Distance Sensor (LDS)

Along with the LDS that scans the room at 5x360 degrees per second, Roborock use the SLAM algorithm. The Laser Distance Sensor maps out the interior helping the robot better navigate while the Simultaneous Localization and Mapping calculates the most efficient way of cleaning without getting lost and provides more efficient performance.

Sensors that help navigate the Xiaomi Roborock

Xiaomi Roborock is equipped with 13 sensors including LDS that help the robot navigate and provides better cleaning performance.

  • The 4 cliff sensors help the robot avoid the failure.
  • A wall sensor keeps the device from bumping at a distance of 10 mm.
  • Roborock was designed with 3mm slight collision and an extra soft crash bumper to protect your furniture.
  • A technology called the "omnidirectional pressure sensor" can now avoid areas where the robot bumps with its "head".
  • The drop sensor activates when the robot is lifted so it stops working immediately.
  • Double Electronic Sensor identifies virtual walls.
  • With infrared technology, the charging back sensor makes recharging more efficient.

Washable HEPA filter

The E11 washable grade filter designed with a Teflon cover provides 95% effective cleaning. Wash it with water, let it dry, and the robot is ready to go; but do it only once in a week. Xiaomi doesn't include extra filters, so you have to change it once a year.

Low noise operation even with the powerful motor

Even the tough Roborock has a powerful motor that works at a low noise level because of its new cotton and porous air sleeve construction. The robot will not disturb you while working.

Operate Roborok with the upgraded MiJia App

The new MiJia app deserves bit more attention since it is really great compared to everything we've seen. Three processors located inside the robot track its movements in real-time. The new Mijia application syncs with the Roborock so you are able to see the map of the house and easily navigate the vacuum by drawing the special area of the map on your phone (as shown on the picture below). This feature is incredible because the robot can clean a specific area of your home without actually using a virtual wall or just blocking it. You can also navigate the robot by tapping on your screen and it will go towards the target.

You need to drag the scan box on the phone map to set the cleaning area using the MiJia app

The Mijia app allows you to monitor the cleaning process, schedule the cleaning time whenever you want (even multiple times in a day), create virtual walls, upgrade to the new version, and choose the name of your new friend. You can track the whole process and manage your robot even when away from home.

Recharge & Resume Feature

The improved charging base has a protection from an over-current, overvoltage and short circuits. When the robot's battery runs out, it will find the docking station using 2 laser sensors.

It is good to have the recharge and resume feature. If you have a bigger household than average, the Xiaomi Roborock will automatically clean on its own after recharging in case it didn't cover the whole area on a single charge. But in most cases, 2.5 hours of working is enough to clean the entire house, so Roborock would probably complete its job without returning after the battery is full.

Who 2nd Gen Xiaomi Roborock was designed for?

The Xiaomi Roborock comes with a lot of features that will make your life much easier, especially when it comes to cleaning your floor.

  • The robot is the perfect alternative to an upright cleaner for people who have pets because the tangle-free design makes it easier to collect long human hair along with pet hair without getting tangled around the main brush.
  • It is perfect for all bare floor types including tile, laminate and hardwood because of the mopping feature. Now you don't need to worry about wet cleaning. Just install the water container and click “Start” using your smartphone or manually press the "Home" button.
  • Roborock's powerful motor is designed to deep clean houses with mostly carpeted surfaces.
  • For those with a bigger house than average, this device is ideal because of its long working time and recharge & resume feature. While other robots randomly navigate for about 100-120 minutes and get recharged when the battery runs low, Roborock cleans the whole place for 150 minutes and resumes after recharging from the where it stopped.
  • Because it is an app-based robovac, you can manage it from your phone. For example, if you need to clean the floor because visitors are coming in the evening, but you are not home, just press "Start" on your screen and by the time you are home, Roborock will have already finished its job.
  • HEPA filtration inside is good for people subject to potential pulmonary side-effects like asthma and allergies.

the difference between the second generation of the new Xiaomi MiJia Roborock vs Xiaomi Mi Robot Vacuum

Is Xiaomi Roborock worth buying?

The second generation of the Xiaomi MiJia Roborock is definitely better than the Xiaomi Mi Robot, but the price of the device is higher. The suction power of 2000 Pa is enough to pick up long human or most pet hair; and if you have any carpeted surfaces, this vacuum cleaner is perfect for deep cleaning. Plus, the tangle-free technology is an amazing feature for those who don't like to rid all the brushes of everything stuck in them. Constantly untangling stuck hair can be really annoying. Do not forget about the new mopping function because it is a rare feature that makes the Roborock good enough for any surface including hardwood floors, tile, laminate, and carpeting. The upgraded navigation technology allows the robot slide through rooms without bumping into things, mapping the area and choosing the most efficient path to work. The MiJia app is phenomenal; it has a lot of things that even Roomba robots don't do. In any case, it still can be an expensive robot vacuum cleaner with a $600 price tag. But will you find anything similar to the Xiaomi Roborock for the price of $550, having all the features and great cleaning performance? So the main question is the second generation of Xiaomi Roborock vacuum cleaner worth buying? Definitely yes!
