Lenovo X1: The first robot vacuum cleaner from a popular computer manufacturer

Today, we'll introduce you to the Lenovo X1, a fascinating robot vacuum cleaner for wet and dry cleaning of various flooring types: ceramic tile, marble, wood, linoleum, laminate, carpet, and rugs. This robot vacuum cleaner is equipped with laser navigation and mapping and can sweep, mop, and even perform both simultaneously. It also features a NIDEC brushless motor (Japan), delivering superior suction power of up to 2200 Pa. This is a significant improvement compared to competitors in the market. Incidentally, the manufacturer specializes in computer equipment and mobile devices, but has also decided to enter the robot vacuum market. Let's take a closer look at the Lenovo X1, including its features, specifications, and functionality.

Equipment

The Lenovo X1 package includes:

1. Robot vacuum cleaner.
2. Charging base.
3. Power adapter.
4. Brush for cleaning the dust collector.
5. Mop for wet cleaning.
6. Operating instructions in German and English.

The kit does not include a remote control or a motion limiter in the form of a virtual wall or magnetic tape. All this functionality is available via a smartphone app, offering a modern and convenient solution.

Appearance

Viewed from above, the robot vacuum cleaner has a round shape. It is made of black plastic with a gold trim. The Lenovo X1's dimensions are quite compact: 350 x 350 x 100 mm. This allows the device to reach hard-to-reach places and clean surfaces.

The top of the robot features a dust collector compartment cover, a pair of backlit control buttons, and a laser rangefinder (lidar) protruding from the body, which is responsible for high-quality navigation.

The front of the Lenovo X1 features a protective bumper with a set of infrared sensors, while the back houses the charging contacts for the docking station and ventilation holes.

The rear of the robot vacuum cleaner features side drive wheels, a front steering wheel, a battery compartment, one side brush, a central turbo brush, and an additional set of sensors for various purposes, including a gyroscope. Importantly, thanks to its design, the robot can overcome obstacles up to 20 millimeters high, which is also not possible for every robot.

Functional capabilities

The robot vacuum cleaner uses a laser rangefinder (lidar) as a navigation system, which allows it to scan the surrounding space and create a map to remember the location of furniture and other interior items, so as not to miss any areas while cleaning.

Furthermore, the Lenovo X1 is equipped with a set of 22 sensors that help the robot navigate its surroundings, protecting the robot body and furniture from damage. If the robot gets stuck under any furniture, it can free itself. However, if the Lenovo X1 gets stuck in the same spot more than once, it will notify the user to set a no-go zone in that area to prevent the robot from entering it again, getting stuck, and wasting time trying to free itself.

The Lenovo X1 features a 585-milliliter dust bin and a separate 170-milliliter water tank. The water tank is intelligent: when the device is not moving, the water stops flowing. The robot vacuum cleaner can perform dry and wet cleaning separately, or combine both.

Remarkably, it can recognize carpets and increase suction power for more effective and thorough cleaning. You can also set mop-free zones when the machine is in mopping mode, preventing it from going onto carpets, for example.

Lenovo X1 has the following operating modes:

• Quiet (600 Pa);
• Standard (1000 Pa);
• Powerful (1500 Pa);
• Max (2200 Pa).

Maximum suction of up to 2200 Pa is provided by a brushless motor of Japanese manufacture NIDEC, which is installed in Okami robotic vacuum cleaners And XiaomiDespite its high performance, the noise level during operation does not exceed 55 dB. Thanks to its powerful motor, the robot can suck up not only large and small particles of dust and dirt, but also hair and pet fur.

In this review, I'd like to highlight the functions that can be configured through the app:

1. AI section – here the generated map is divided into separate rooms (sectors) to make cleaning easier for the robot vacuum. You can also set a cleaning schedule here.
2. Individual cleaning is the designation of a specific rectangular cleaning area.
3. Fixed sequence of cleaning of room sectors.
4. Local cleaning of a small area.
5. Deep Cleaning – You can set this feature to have the robot vacuum cleaner go over certain areas twice.
6. Scheduled cleaning.
7. Virtual wall mode.
8. No mop area.
9. Multi-level mapping – the ability to store more than one map, which is ideal for multi-story buildings.

In general, the robot vacuum cleaner is equipped with all the necessary functions and is, to a large extent, a copy of such models as 360 S7, Xiaomi Roborock S6, Okami U100 etc.

Advantages and disadvantages

We conclude our review, as usual, by listing the main advantages and disadvantages of the Lenovo X1 robot vacuum cleaner.

Pros:

1. Stylish design.
2. Compactness, maneuverability, cross-country ability.
3. Powerful battery.
4. NIDEC brushless motor.
5. High suction power up to 2200 Pa.
6. Laser navigation, cartography.
7. Dry + wet cleaning.
8. Low noise level.
9. Convenient control from your smartphone.
10. Zoning of premises into rooms.
11. Restricted areas in the application.
12. Save multiple cleaning plans.

The model doesn't have any particular drawbacks. It's important to note that the price is around $300 in 2019. However, as we've already mentioned, the robot vacuum cleaner is practically a copy of the Roborock S6 (and in some ways, Xiaomi Mijia STYTJ02YM) or the 360 ​​S7. However, in our objective opinion, it's better to choose time-tested robot vacuum cleaners than Lenovo's experimental copy.
