Xiaomi Mi Robot Vacuum Cleaner 1S: A New Level of Navigation

Another new product of 2019 from the well-known company Xiaomi is the Xiaomi Mi Robot 1S, or as it is also called, the Mijia 1S. This is an updated model of the first generation (Xiaomi Mi Robot Vacuum Cleaner), which has upgraded navigation, suction power, and other important features. It's worth noting right away that this model is not suitable for mopping floors, so it can be considered the company's flagship among robot vacuum cleaners designed for dry cleaning. The new one can be considered the absolute flagship. Roborock S6, which was also released recently. In this article, we provided an overview of the Xiaomi Mi Robot 1S, examining the specifications and features of the new model.

Equipment

The delivery set is, as always, meager and includes:

1. The robot vacuum cleaner itself.
2. Charging base with power cable.
3. Brush for cleaning the filter.
4. Instructions.

There are no spare parts, so it is better to order replacement filters, main and side brushes immediately upon purchase.

Appearance

The design of the new Xiaomi Mi Robot 1S hasn't undergone any significant changes. The only immediately noticeable feature is the camera on the top panel, next to the navigation buttons. This is the key element of the upgrade, but more on that later.

Otherwise, the robot, like its predecessor, is equipped with a lidar, two control buttons, and a mechanical touch bumper.

At the bottom there is one side brush, a central bristle-petal turbo brush, a swivel roller, wheels and various sensors.

Technical specifications

The changes in specifications are minor, but they do exist. Suction power has increased to 2000 Pa compared to 1800 Pa in the previous model. Now the robot vacuum cleaner performs even better on carpets, as well as removing debris, sand, and pet hair from floors. The robot's diameter has also increased by 5 mm. The remaining specifications of the Xiaomi Mi Robot 1S are as follows:

Battery	Li-Ion 5200 mAh

Features - What's New

Now comes the most important part of the review, where we'll cover the new features and capabilities of the Xiaomi Mi Robot 1S. Let's start with the most important part: the camera.

The robot vacuum now navigates and maps its surroundings using not only a laser rangefinder but also a built-in camera. The new navigation system, according to the manufacturer, has increased cleaning efficiency by 13%.

Here's how the new navigation system works: a laser rangefinder scans the room and creates a plan, while a camera allows you to determine the location of doorways to plan the most efficient cleaning route.

The new Xiaomi robot vacuum cleaner divides the room into rooms, allowing you to select specific rooms for cleaning in the app. This is very convenient and allows you to plan your cleaning precisely.

The Xiaomi Mi Robot 1S is also equipped with a new quad-core Conrtex-A35 processor, which reduces power consumption by 10% and improves performance by 40%.

Speaking of the app, you can now define the cleaning zone directly on the map (virtual wall), select the desired area for floor cleaning, monitor the cleaning process in real time, and program the robot not only to turn on by day of the week, but also by time.For example, you can set a schedule so that the robot vacuum cleaner cleans the living room twice a week at 1:00 PM, and the bedroom and kitchen three times a week at 10:00 AM. Flexible settings allow you to optimize the cleaning process and make it more convenient for users.

The final important change is the ability to control the robot via the proprietary Xiao Ai voice assistant. Now, using voice commands, you can check its status, start cleaning in a specific room, or inquire about its battery life. This is very convenient, but it would be great if the model also supported more familiar voice assistants like Alexa and Google Assistant.

Let's sum it up

Having analyzed all of the above, let's highlight the main pros and cons of the Xiaomi Mi Robot 1S robot vacuum cleaner. Among the advantages, we can highlight:

1. A new level of navigation and spatial orientation.
2. Extended functionality of the mobile application.
3. Flexible settings for cleaning schedule and route.
4. High suction power.
5. Capacious battery, long operating time on one charge.

At the same time, the disadvantages of the model are as follows:

1. Small dust collector.
2. Poor equipment.

Overall, the shortcomings are typical for most Xiaomi robots, but this doesn't stop them from reaching the top of ratings and becoming bestsellers. Specifically, this model is clearly better than its predecessor, the Xiaomi Mi Robot Vacuum Cleaner, and its navigation is better than that of the Roborock S50. Meanwhile, the price of this model in 2019 is around $200. For this price and with such functionality, there are simply no comparable products when it comes to dry cleaning. This model is clearly worth the money and is one of the best in its budget class.
