LG VRF6640LVR

This article provides a review of the VRF6640LVR robot vacuum cleaner from the renowned and globally popular Korean manufacturer LG. This device is designed for cleaning hard floors (laminate, linoleum, tile, wood, etc.), as well as carpets and rugs with increased suction power. This model features a sophisticated navigation system, a wide range of operating modes, and remote control via a smartphone app. We've provided a detailed review of the LG VRF6640LVR, including its specifications and features, below.

Equipment

The basic package of the LG VRF6640LVR includes:

1. Robot vacuum cleaner.
2. Charging base.
3. Power adapter.
4. Remote control (RC).
5. Two AAA batteries for the remote control.
6. Tool for cleaning device elements.
7. Filter.
8. Microfiber cloth attachment.
9. Napkin (2 pcs.).
10. Operating instructions.
11. Quick Start Guide.

Appearance

The LG VRF6640LVR is made of red plastic and features a square shape with rounded corners, allowing it to better reach hard-to-reach areas (under furniture, along baseboards, in corners, etc.) and clean more effectively. This design is typical of most of this manufacturer's robotic cleaners.

When viewing the robot vacuum cleaner from the front, we see the camera, which is responsible for the robot's navigation, the screen and control button, as well as the dust collector compartment cover with the corresponding button.

The front contains ultrasonic sensors, obstacle detection windows, charging station detection sensors, and remote control signal reception sensors. The rear housing houses the power switch and ventilation opening.

The back of the LG VRF6640LVR robot traditionally features drive wheels on the sides, a swivel wheel in the front, a battery compartment, charging contacts, side brushes, one main brush in the center, and height sensors.

Functional capabilities

Let's take a look at how this robot cleans. The robot vacuum cleaner cleans using a central brush and two extended side brushes. Dirt is sucked through a suction channel into a 600-milliliter dust bin, which is additionally equipped with a replaceable HEPA 11 filter for more effective filtration.

The LG VRF6640LVR uses an inverter motor, which ensures high-quality cleaning and has a longer service life than the brushed motors found in other models from the Korean manufacturer.

The robot is equipped with a "digital bumper," a set of multiple sensors that detect obstacles and prevent collisions. Ultrasonic sensors allow it to "see wider" and even recognize glass objects, stopping early before they occur. A cliff sensor, in turn, helps prevent falls from elevated surfaces.

One of the key distinguishing features of the LG VRF6640LVR is its Dual Eye 2.0 camera system. The upper camera allows the robot vacuum cleaner to recognize its location, track its path, and plot a new route regardless of room lighting. The lower optical flow sensor simultaneously collects data from the floor surface.

Let's move on to a review of the LG VRF6640LVR's functionality and examine the robot vacuum cleaner's main operating modes:

1. "Zigzag" mode: In this mode, the robot moves forward and backward until it detects obstacles. It's effective for rooms with limited furniture and other interior items.
2. "My Spot" is designed for cleaning specific areas twice in Zigzag mode. Suitable for any obstacle-ridden area.
3. "Cell by Cell" is a more complex mode in which the LG VRF6640LVR, after cleaning in a zigzag pattern, moves to the next section. It's best suited for rooms with a lot of furniture.
4. "Spot" mode is used to clean the dirtiest areas. In this mode, the robot vacuum cleaner moves in a spiral pattern, creating 1.5-meter circles.

Overview of additional features:

1. Turbo - increases motor rotation force and suction power to improve overall cleaning efficiency.
2. "Smart Turbo" - starts automatically when the robot moves to carpeted surfaces.
3. Repeat mode - for a more thorough cleaning, the robot vacuum cleaner repeats work cycles until the battery is discharged, after which it returns to the docking station.
4. "Manual" mode.

It is possible to wet wipe the floor by installing a special nozzle with a pre-moistened microfiber cloth on the bottom of the robot vacuum cleaner.

The LG VRF6640LVR can be controlled using buttons on the unit, the remote control, and the Smart ThinQ smartphone app. You can use the app to view the cleaning log, set a schedule, view the current status of the unit's components, and adjust other settings.

Additional features of the robot vacuum cleaner:

• Automatic installation on the docking station;
• resuming the route after recharging the battery from the last place;
• zoning of premises;
• Wi-Fi network support;
• voice notifications.

Advantages and disadvantages

Considering that the average price of the LG VRF6640LVR ranges from $270 to $360, let's highlight the model's pros and cons.

Positive aspects that were discovered:

1. Camera navigation.
2. HEPA filter 11.
3. Self-study.
4. Self-diagnosis of faults.
5. Zoning and resumption of the previous route.
6. Voice notification and light indication.
7. New generation inverter motor.
8. Suction power regulation.
9. Working in the Smart ThinQ mobile application.

Cons:

1. There is no movement limiter included.
2. Increased noise in Turbo mode.
3. Doesn't remember multiple cleaning plans.
4. Not controlled via voice assistants.
5. There is no wet cleaning function (floor polisher only).

For the same price, you can choose a more functional robot vacuum cleaner, such as an Okami or a Xiaomi. That concludes our review of the LG VRF6640LVR. We hope you found this information useful and interesting!
