• carry out both dry and wet cleaning at the same time;
• map the premises to ensure the best cleaning efficiency;
• clean surfaces using one of the 8 available work options.

This model is ranked 1st in the ranking of the best robot vacuum cleaners for 2020!

Equipment

The robot vacuum cleaner is sold in a cardboard box with a plastic handle for easy portability.

In the complete set:

• actually, a gadget;
• battery recovery docking station;
• network power supply unit;
• remote control;
• filters of the "HEPA" type (3 pcs.);
• side brushes (3 pcs.);
• wipes for wet and dry cleaning (2 pcs. for each type of cleaning);
• nozzles (4 pcs.);
• a container in order to fill the tank with water or detergent;
• manual;
• guarantee coupon.

Important! The package also contains batteries for the remote control.

The charging dock has been redesigned. The manufacturer has added clips, so the owner of the "smart" assistant can mount the base on the wall so that the robot vacuum cleaner does not push it when it comes back to recharge.

Design

The design is similar to the 669. The device is made in a D-shaped form factor with a wide front plate and a rounded back. The body is made of matte black plastic materials. The dimensions of the model are 34x33x9.5 cm.

The glossy front cover has two control keys:

1. Departure to the base.
2. "Start", which combines the option of Wi-Fi restart if the button is held down for 5 seconds.

A container for water or detergent, a compartment for a dust collector and a switch are located under the lifting lid. Along the contour of the U-shaped bumper on a springy stroke there is a rubber pad, which weakens the collision of the “smart” assistant with walls and furniture.

The bumper has 3 holes for laser sensors, and 2 more sensors are located on the sides of the device. The rear part has built-in charging terminals.

If you turn over the gadget, you can see:

• a suction hole that extends across the width of the body;
• two vibration mops, on which werehable (7 mm wide) napkins are fixed;
• between the vibrating wipers there are holes for spraying water;
• wide rubber tracks on the sides;
• on the right (in the corner) an end brush, which looks out from behind the body by about 4 cm;
• in the front corners there are 2 laser-type sensors.

Functional

The first thing to start with is the navigation system. It is laser-based, so the gadget is perfectly defined in a space divided into a maximum of 8 rooms. The robot vacuum cleaner moves in parallel, while not losing sight of untidy places. In addition to laser-type sensors, the model is equipped with an encoder (steering angle sensor), an electronic compass and a gyroscope.

Cleaning Modes

The "smart" assistant knows how to put things in order in 8 modes:

1. "Standard". Will be an excellent solution for most cases. It should also be used in that situation if you do not yet understand which mode is most suitable for your case.
2. "Kitchen". Use this mode to clean stubborn stains that often remain in the kitchen. The gadget will break the room into blocks (squares) of one and a half meters and properly moisten them in order to clean the floor from stains. After that, the robot vacuum cleaner performs a second approach in order to completely clean the floor from dirt.
3. "Pet". Without dropping the speed, the device increases the suction power in order to collect pet hair, and also increases the flow of water to the flooring in order to maximally clean the floor of the pets' paws.
4. "Powerful". In this program, the “smart” assistant increases the suction power and travel speed to the limit, as it moisturizes the floor. As a result - fast and high-quality cleaning.
5. "Economical". In this program, the model clears the maximum allowable area, while moving quickly, but with reduced suction power. This mode is an excellent choice for quiet everyday wet cleaning.
6. "Polishing". In this mode, the gadget greatly moisturizes the floor covering and increases the frequency of movement of the napkins in order to qualitatively remove dirt and polish.

Interesting information! The robot vacuum cleaner reduces the movement speed in order to effectively polish the floor and clean up dirt

7. "Dry". The smart assistant cleans the floor without splashing where the surface cannot be wetted. To do this, the robotic device deactivates the liquid spraying system and increases the suction power, which allows the dust that has accumulated on the surface to be collected.

Interesting information! The cleaning rate in this program is kept at a high rate, which saves time.

8. "Custom". The manufacturer has provided the ability to create a cleaning mode directly by the user. The owner needs to set the key characteristics of the spraying, the suction power, the frequency of reciprocating movements of the wipes and the speed of the gadget.

Important! You can set up a custom mode as conveniently as possible using a smartphone app.

Cleaning FastBrush

In fact, the novelty is a 2-in-1 model, since the “smart” assistant can carry out both wet and dry cleaning at the same time. The essence of the device is a four-stage FastBrush system:

1. stage. The powerful brushless motor ensures effective cleaning of pet hair and other contaminants by sending the collected waste to a dust collector with a volume of 0.5 liters. There, the air passes through a two-stage cleaning system through a high-purity mesh and filter, which retains microparticles of dust.
2. stage. The dirt that the device could not remove with the pump is held on a microfiber cloth that moves at a speed of 10 reciprocating movements per second. Due to static, dust is retained between the fibers of the napkin and does not fly off during the further cleaning process.
3. stage. The gadget sprays water in a measured and balanced way on the floor, moisturizing it before wet cleaning.Water (or detergent), which is in the 320 ml container, flows through the nozzles, while the amount of liquid changes depending on the current mode.
4. stage. The final stage of putting things in order in the room is reduced to cleaning the remaining dirt and sucking in moisture through the back microfiber cloth. Due to the fast reciprocating movements, the floor covering is cleaned of dried dirt, and then polished.

Important! The frequency of the reciprocating swipe changes depending on the activated mode.

The garbage container (0.5 l) is enough for a couple of cleaning sessions. When the container is full, the user will receive a notification on the phone, and the robotic assistant will make a distinctive sound.

Interesting information! The trash tank is equipped with a two-stage filtering system, which includes a fine mesh and a HEPA filter for fine air purification.

Operating modes

There are three basic operating modes, as in previous models:

1. Zigzag movement. During zigzag movement, the device cleans the entire area, moving in parallel and not losing sight of a single corner, focusing on the map of the premises.
2. Moving around the perimeter. The gadget bypasses the area along the contour, thoroughly removing the corners and baseboards. The face brush effectively sweeps and transports dirt to the vacuum channel.
3. Cleaning in automatic mode. In this mode, the robot vacuum cleaner first cleans the room along the contour, and then removes the remaining space, moving in a zigzag pattern.

Mapping

When you turn it on for the first time, the gadget generates a map of the cleaning rooms, marking the cleaned space, furniture, walls and other barriers on it. The constructed map is saved in the device's memory. The “smart” assistant uses it for further cleaning, which significantly improves the quality of cleaning and saves time. The device "looks" into every corner of the room and accurately recognizes the areas in which it needs to put things in order.

Cleaning diary

The gadget records information about the work done. The information is available to the owner in the smartphone app. This allows the robotic assistant to be monitored. Available to the user:

• information on areas harvested;
• duration of cleaning and other information.

The report clearly identifies the tasks that were assigned to the device. If he did not remove some section of the territory, for example, he could not get there due to an obstacle, then it is possible to give him an order regarding the cleaning of the missed area, having removed the obstacle in advance.

timetable

The gadget can clean up the room according to the schedule, taking into account the day of the week and time. The owner can, for example, set up cleaning for a time when there is no one in the room so that the robot vacuum cleaner does not get in the way. Upon completion of the scheduled cleaning, the gadget will return to where it started from.

Sensors

Putting things in order in the room, the robot vacuum cleaner is accurately determined in space due to the system of sensors, including:

• gyroscope;
• rotation angle sensor;
• electronic compass;
• laser sensors.

The model recognizes obstacles in the path of movement and decisively overcomes them, returning after this to a given course. Thanks to laser-type sensors that are integrated into the body of the robot vacuum cleaner, it easily recognizes differences in floor heights in front of it.

Pros and cons

Having studied the technical parameters specified by the manufacturer, as well as personal experience of use, I would like to note the strengths and weaknesses of the model.

• fashionable appearance in a D-shaped form factor;
• makes both dry and wet cleaning at once;
• excellent indicators of autonomy;
• multi-stage cleaning (FastBrush);
• high suction performance;
• well thought out navigation system, which consists of optical and laser sensors, as well as an electronic compass and a gyroscope;
• drawing up a map of the premises in real time;
• fluid inlet and monitoring in automatic mode;
• eight cleaning programs (Talent Clean);
• you can control the robot vacuum cleaner through a mobile program;
• cleaning according to the schedule;
