HOBOT Legee 668

Taiwanese company HOBOT INC. is best known for producing excellent window cleaning robots, but the company's HOBOT Legee 668 floor cleaning robot also quickly won the hearts of many customers worldwide. This model can safely be called one of the few fully functional washing robotic vacuum cleanersHowever, the device is capable of not only cleaning the floor with two mops at once, but also vacuuming regular debris and dry mopping it simultaneously. Therefore, it would be more accurate to describe the device as a hybrid robot vacuum cleaner and mopping robot. It can be used in both residential and office spaces on any type of flooring, whether parquet, ceramic tile, linoleum, or carpet. The device can automatically recognize the surface in front of it and select the most appropriate program and cleaning method. Today's review of the HOBOT Legee 668 will allow us to take a closer look at this unique hybrid robot.

Equipment

Let's take a look at what's included in the HOBOT Legee 668 package:

1. Robot vacuum cleaner.
2. Charging base station.
3. Power adapter.
4. Power cable.
5. Extension cord (4 m).
6. Remote control.
7. Three filters for air purification.
8. Set of three blade brushes.
9. Brush for cleaning the dust collector.
10. A set of three dry cleaning wipes.
11. A set of three wipes for wet wiping the floor.
12. Instructions for the robot.

Appearance

The HOBOT Legee 668 robotic vacuum cleaner features a D-shaped design, allowing it to easily adhere to walls and effectively clean along baseboards and in corners. The vacuum cleaner has an ultra-modern and stylish appearance, with a black plastic body that adds a touch of elegance.

The front panel is bare except for the dust bin cover and control buttons. The charging contacts and a soft bumper are on the side of the robot vacuum.

The fundamental design feature of this vacuum cleaner is the presence of two movable platforms on the bottom, which hold felt pads. These platforms ensure the smooth operation of the mop unit and allow for both dry and wet cleaning. The caterpillar drive ensures the unit doesn't slip or get tangled in cords or long objects. Various sensors, including a gyroscope, electronic compass, and more, are also located throughout the body.

Functional capabilities

Legee features an advanced navigation system that allows the robot vacuum cleaner to avoid obstacles and objects, accurately plan its cleaning route, and efficiently use its battery. The HOBOT Legee 668 uses a combination of laser and other sensors to map the room and determine its current location. Using three laser rangefinders, the robot determines the distance to walls and surrounding objects and, based on this information, creates a room map using the SLAM method.

The robot vacuum cleaner has the following operating modes:

• automatic cleaning of the entire area;
• fast cleaning along parallel lines;
• effective cleaning around the perimeter (along walls and in corners);
• local (local) cleaning of a specific area.

However, the main distinguishing feature of the HOBOT Legee 668 is its exclusive patented four-stage floor cleaning:

1. The vacuum cleaner powerfully sucks up dirt, hair, and fur from the floor and directs it into the dust collector with a double filter, allowing for thorough cleaning of the surrounding air.
2. The drive mechanism with a reciprocating motion of two dry cleaning cloths for floor coverings, oscillating ten times per second, imitates the movements of human hands to remove dried stains and dirt.
3. Micro-droplet spraying of liquid from special nozzles softens dried-on and stubborn stains and dirt that cannot be removed with regular dry cleaning.
4. The cleaning felt cloth at the rear of the undercarriage not only wipes and absorbs any remaining liquid and removes dirt from the floor surface, but also polishes it as a final step in cleaning.
