In this era of pursuing intelligence, many products are seeking more humanized and intelligent innovation. In such a market, traditional electrical products have encountered the best times and the worst times. Abide by the tradition and be doomed to be drowned by the market torrent; In pursuit of innovation, once successful, it will be an achievement of "going to the next level", but if failed, it will be a loss like "sinking a stone into the sea". Nevertheless, the sinking of "Nokia" encouraged the whole electronic market to march forward, so the various combinations of smart watches with air test, TV boxes with remote control of household appliances, and speakers with pre agreed delivery appeared in front of consumers. Many people are surprised by such innovation, but more people hold a wait-and-see and skeptical attitude.

The sweeping robot is a good partner for urban families to clean the floor. The author is lucky to use this sweeping robot with navigation function - inxni internal navigation sweeping robot, which has realized the functions of automatic cleaning, automatic cruise, fixed-point cleaning, automatic homing, etc. in the name of navigation. Whether the application of navigation really brings convenience to the sweeping robot, Or is it just a selling point of the product? Please continue to browse below and let us wait and see.

Full sincerity in unpacking

When I received the internal navigation robot, I was attracted by its heavy packaging. Fashionable outer packaging paper is high-end. It is totally different from the traditional hard paper shell packaging of the floor sweeper. It is not like the packaging of a home appliance, but more like the packaging of a fashionable home gift. Even if you are carrying a housewarming gift to send relatives and friends, it is also generous and appropriate.

  ‍

Spreading out the random accessories shows their sincerity. The main components include: a floor sweeping robot host, a group of landing charging ports, a remote controller, a power supply, a product manual and a warranty card; Spare parts include: a quick disconnect driver, a side brush, a filter cotton, a cleaning brush and 8 gaskets.

  ‍

The interior navigation floor sweeping robot host adopts fashionable orange, which does not stick to the gray and black of traditional floor sweeping machines, making it look more fashionable and interesting. Its packaging pays great attention to details. For example, the bumper strip is added at the buffer plate, and the protective cover is set for the recessed switch, which is sufficient to show the sincerity and intention of the manufacturer.  

The right angle of the charging port is very straight, the contact and opening position are accurate, and there is no roughness at the opening. The side is gray, the bottom is black, and the middle is still orange. The color contrast design not only ensures its good dirt resistance, but also shapes a fashionable home style.

Construction and description

The main structural parts within are distributed below, including 3 sets of down looking sensors, 2 butt joint plates, 1 universal wheel, 1 edge brush, 2 driving wheels, 1 battery box, 1 adhesive brush, 1 brush and 1 dust box. Although the overall distribution is relatively compact, it is just right.

  ‍

The buffer impact plate is not set with a relatively wide buffer gap like the ordinary sweeper, on the contrary, the actual buffer gap is relatively small (about 1cm), which is also a humanized improvement from the previous sweeping mode of "sailing by collision", which not only ensures the round appearance, but also makes the whole machine look more solid.

Take a look at the driving wheel inside. The main feature is that the gear is deeper, which also makes its grip more firm, more stable and more powerful. Although from the existing technical level, the 2600mAh battery equipped with the sweeper does have a large room for improvement, due to the reasonable design of the driving wheel and gear, its endurance can reach about 2h, which can also meet the daily use.

  ‍

Although the design of the driving wheel is relatively high, it will automatically sink a part after bearing its own weight. In fact, the elasticity is good when pressed, and it will not be loose when used for a long time. This elastic driving wheel makes it more suitable for complex cleaning environment and has more "off-road" performance.

‍

With the front universal wheel, the footwall is relatively stable. The design of universal wheels makes it easier to turn and guide. In practice, the setting is flexible, and it is also necessary to adapt to complex cleaning scenes.

Looking at the working conditions of the rubber brush and the brush during its operation, it is not difficult to see that they should rotate synchronously. The rubber brush is responsible for the cleaning of larger hard debris, and the brush is responsible for the cleaning of dust and fine particles. The combination of the two is cleaner and more efficient.

Automatic charging is the preferred charging mode for the current "fashion lazy people". The contacts on the charger are set on two raised bases in a spherical shape, which does not affect the rolling contact of the internal navigation sweeper when it is in place, but also makes the contact surface more compact. At the same time, the 18V output voltage of the adapter also ensures the safety of the exposed contacts.

A large area of laser scanning area is set in front of the internal navigation sweeping robot, and the effective scanning distance is 7m. The composition analysis is carried out according to the situation in front of the scanning robot, and the direction of advance is directly guided independently. At the same time, three small laser scanning areas are set on both sides to scan the situation on both sides while moving forward.

The dust box is set at the back of the machine body, and is fixed in a snap type way. It can be easily removed by one hand. The dust box is arranged in an arc shape, and a fan box (independent design) is set in the center to make it more uniform in the air around. Open the baffle, there is a layer of filter cotton inside, and the box body is actually set with two windows on the left and right, which seems a little small.

Use and experience

 ‍

First, we had a group of experience videos, in which the author recorded the cleaning steps of the internal navigation sweeping robot, the wood floor cleaning demonstration, the kitchen tile floor cleaning demonstration, the obstacle bypass demonstration, and the ridge crossing demonstration.

  ‍

The internal cleaning steps are from the periphery to the middle. For the wooden floor in the bedroom, the author simulated the scene of hair, paper scraps, melon seed shells and straws to test. The cleaning of paper scraps, melon seed shells and straws was relatively thorough, but the straws that accidentally appeared were stuck under the glue brush, which showed that for long and narrow debris, the machine could not be cleaned within the area, and even might be stuck. In addition, about 60% of the long hair in the bedroom is swept to the dust box, and 40% is wrapped around the edge brush.

  ‍

For the small grid tile kitchen, the author simulated the cleaning environment of making chili sections, chili handles, mung beans and garlic shells. The actual test results show that the internal navigation sweeping robot is easy to sweep round mung beans into the corner while brushing, and small mung beans are easy to get stuck in the low slot, and the cleaning of other debris is relatively smooth.  

‍

Then, the author added a stool on the regular route. When encountering obstacles in the internal "bow shaped" cleaning process, it needs to go through three collisions to determine the existence of obstacles, which can effectively eliminate the impact of the crowd.  

‍

At the same time, the author also tested the condition of its crossing the sill, and found that the height of 10mm is relatively easy up and down, but for the right angle height of 20mm, it is slightly difficult. PS： The cleaning noise is greater on the plastic foam pad.  

‍

The internal navigation sweeping robot also has the function of anti falling. The author places it on the tea table, and it still follows the sweeping mode of four weeks first and then the middle in a small area. Although the speed of travel is relatively fast, the effect of anti falling is relatively reassuring.

‍

After the decibel meter test, the noise of the navigation sweeping robot within 1m range is 65.3 decibels, which can affect the normal rest of people. It is recommended to avoid the rest period of relatives and friends when cleaning.  

‍

After cleaning, the filter cotton on the dust box can be taken down and washed directly with water. It is recommended to dry it with a blower after washing and then install it again.  

APP experience

  ‍

The internal navigation sweeping robot supports user-defined sweeping and can set multiple sweeping tasks. It is practical to arrange cleaning at the time when people leave the room, which can avoid noise disturbance and "flowing obstacles" affecting the cleaning work. At the same time, fixed-point cleaning is also supported within the area, and the sweeping robot can be controlled to drive to the designated place to clean the ground within 1m, but the accuracy needs to be improved. Another thing I have to say is that although the firmware has been upgraded during use, the WIFI connection is still unstable.

  ‍

On the APP, we can see the working position and working status of the internal navigation sweeping robot in real time. At the same time, it can also clearly distinguish between areas that have been heavily cleaned and areas that have not been cleaned at a glance. Although the navigation scanned the layout of the room, when the author mischievously moved it directly from the charging port to the next room, he started the command to return to the charging port, and it completely lost its direction.

Summary and suggestions

  ‍

The appearance design of the interior navigation sweeping robot is fashionable, and the design of the navigation carpet scanning and cleaning method, the design of automatic charging back to the charging port, and the active custom appointment function design are fashionable, which meet the needs of consumers. The ground is clean, and the improvement of fine dust is particularly obvious. Although navigation is not just a sales gimmick, there is still room for improvement. It is suggested to improve or enhance the following aspects:

1. The endurance needs to be improved, and 4000mAh is relatively acceptable.

2. The cleaning ability of long hair needs to be improved.

3. The driving force of the return mode is too low, which affects the main engine's return to the charging port (the author has no choice but to encounter the situation that its return is blocked by a doormat during the test). It is suggested to design a passive speed increase drive, that is, to speed up the return when encountering obstacles.

4. The dust box is too small to hold more sundries.

5. The alarm function is not perfect, and it is unable to provide alarm preparation or fault information. It is recommended to add alarm for excessive resistance of filter cotton, alarm for obstacle impassability, alarm for disorientation, and set different alarm signals to show the difference.
