HOBOT Legee-669
This review will focus on the HOBOT Legee-669 model, which is part of a line of three robotic vacuum cleaners: Legee-668, 669 and 688The robot in question differs from its “brothers” in a number of technical parameters (suction power, cleaning area, noise level, battery life), as well as in price: $289.90 versus $259.90 for the 668 model and $349.90 for the 688 model. HOBOT Legee 669 is designed for cleaning smooth floor coverings, including: tiles, stone, parquet, laminate, linoleum, etc. It can clean the floor not only from dust, sand, hair and wool, but also collect larger debris such as rice, peas and bread crumbs. And thanks to the full wet cleaning function, the robot vacuum cleaner can wipe off even dried dirt stains from the floor surface without leaving wet marks. Therefore, it can safely be classified as washing robotic vacuum cleanersWe told our readers about the robot's features in more detail. robovac.washerhouse.com further.

Appearance
The robot vacuum cleaner is made of black plastic and has a D-shaped body, which allows it to sweep out debris even from hard-to-reach places, including spaces along walls and in corners.
When viewing the device from above, we see only two control buttons and a lid, under which is located a waste container and a water tank.

The robot has a protective bumper at the front and contact pads at the back for automatic charging of the battery on the docking station.
Front view
The bottom of the HOBOT Legee 669 has tracks for moving the robot along the surface, a side brush, a suction hole, a micro-droplet water spray system, and two moving platforms with cloths for dry and wet cleaning.

Functional capabilities
What is the Legee navigation system in the HOBOT 669 robotic vacuum cleaner? It's a combination of laser sensors, a rotation sensor, a gyroscope, an electronic compass, and other sensors.
Navigation
This navigation system enables the robot vacuum to plan a cleaning route, efficiently using battery power and minimizing battery life. The robot determines its current position in space and the distance to nearby objects, and builds a room map using the SLAM method, allowing it to avoid collisions and falls from heights.
The HOBOT Legee-669 robot vacuum cleaner cleans and mops floors using a patented 4-step technology called “FastBrush”:
- The vacuum cleaner sucks up small debris, pet hair, and hair, directing them into a 500-milliliter dust container with a mesh filter and a HEPA filter, which thoroughly clean the exhaust air.
- The drive mechanism with reciprocating movements of cloths on moving platforms at ten oscillations per second creates an imitation of the movement of human hands to clean the floor from dried stains.
- Micro-droplet spraying of water through special nozzles from a 320-milliliter tank allows you to soften very old stains that cannot be removed by dry wiping the floor.
- The back cloth allows you to wipe the floor dry and absorb any remaining moisture, polishing the surface.
Cleaning technology
Operating modes of the HOBOT Legee-669 robotic vacuum cleaner:
- zigzag – the device moves in a zigzag pattern, cleaning the entire available area of the room;
- along the perimeter - HOBOT Legee-669 moves only along baseboards and furniture, and also cleans out debris from corners;
- Automatic – is a combination of the two previous modes, in which the robot first scans the space, then switches to the “Zigzag” mode, and finally cleans the floor around the perimeter.
Remote control
It's important to note the improved automatic cleaning mode for large rooms: to optimize and improve cleaning quality, the vacuum cleaner divides a large room into sections, moving through them in a zigzag pattern, and only then moves on to cleaning around the perimeter.
The HOBOT Legee-669 features high suction power (1800 Pa), long service life and low noise levels thanks to its high-performance brushless vacuum motor and metal fan impeller.
