To say which robot product is the most discussed recently, it must be the sweeping and dragging robot S7+ launched by Roborock Technology this year! The S7+ has a newly designed rubber main brush, a mop component with increased downforce and high-frequency sonic vibration, and a fully automated rechargeable dust collector, bringing users a more efficient and comprehensive cleaning experience. The consistently affordable price of the above brand can be said to have dropped a shocking bomb in the robotics market. How about the S7+, which emphasizes that the sweeper has been upgraded in all aspects? Is the dust collector, which mainly reduces the trouble of taking out garbage, really effective? Whether the affordable price is value for money or an exaggeration, let Xiaobian tell you through this review!

Before starting to introduce the robot, BQ27500DRZT-V120 will first solve the model problem that many people have troubled with. Is there any difference between the mainframes of the S7 and S7+? The answer is no. The S7+ is simply the model name of the dust collection seat set. , S7 and S7+ are exactly the same, and because Taiwan introduced the host of the international version of Stone Technology, the robot only has a "white" color to choose from. (If the model is mentioned below, it will be directly referred to as S7+)

The three solid silver buttons on the top of the S7+ host are the only means of control before the user is connected to the mobile device. The functions from left to right are local cleaning and safety lock (long press), cleaning and power on and off, and recharge buttons. . Accidental touches may cause the host to start up, so this time the S7+ has a safety lock function. After long pressing, the host will suspend all responses. Even if children or pets in the house accidentally touch the host, it will not affect the host. Quite user-friendly design.

Route planning capability has always been a necessary basic function for sweeping robots. In order to accurately plan the cleaning route in the space, the S7+ is equipped with the so-called LDS laser navigation system, which uses the orange laser head in the center of the main unit to sensitively detect the status and status of the surrounding environment. Ranging to plan the cleaning route.

In order to allow the host to accommodate more dirt and garbage, the S7+ has upgraded the capacity of the dust box this time. The capacity of the dust box is 470ml. Even if the dust collector is not used, it can also cope with general household cleaning. Frequent dumping of garbage will be required. As mentioned earlier, since the S7+ is equipped with a dust collector this time, it also comes with another dust collector dedicated to dust collection, but in addition to the stickers on the box surface and the presence of openings on the side of the box, the two types of dust collectors are also included. The dust box is exactly the same in terms of appearance, capacity, filter and other configurations, and the opening on the side of the box corresponds to the air inlet on the inner side of the machine, which is quite easy to identify.

The two dust boxes are equipped with a removable HEPA filter of E11 level to perform preliminary filtration for the dirty air swept into the dust box. A raised handle is set at the Logo, which makes it easier for users to take the filter, and this design also prevents users from directly getting dirty when holding the filter. The cleaning is roughly the same as the dust box. The filter itself can be washed directly with water, but it must be completely dried before continuing to use.

Press the orange button on the front of the main unit, the user can remove the water tank, the gray cover on the left is the water filling hole of the water tank, and the rubber cover with the water drop pattern on it is very easy to identify, but this is the only open holes, it may be a little inconvenient to clean the tank.

As a flagship-level robot model, the S7+ not only has the central orange laser head as the main sensor structure, but also has a recharge sensor on the side of the S7+ that can sense the recharge route and the distance from the wall. In addition, there are wall sensors that ensure smooth cleaning along the wall, and collision buffer sensors that can buffer in time when encountering obstacles.

Then we see the bottom of the main unit, and the complete sweeping and dragging structure of the S7+ can be clearly seen at the bottom. In order to prevent the robot from falling when it is running, up to 6 cliff sensors are also set around the main body. Since the S7+ has invested a lot of effort in mopping the floor to improve and upgrade, this time I want to start with the mopping tray. The removal method of the S7+ mop tray is the same as that of the previous generations. Whether the main unit is on the front or the back, you can easily remove the mop tray by pressing the buttons on both sides of the device. The mop tray is also in the form of clips and devil felt. The mop tray is combined, and the installation and removal are easy to get started.

This time, the S7+ not only changed the mopping cloth to polyester fiber, but also increased the pressure mopping force to 600g (S5 Max is 300g), and was equipped with a new sonic mopping technology. An area that will automatically traverse. The area will vibrate with sound waves at a frequency of up to 3,000 times per minute. With the greatly improved mopping strength, just looking at the data, the S7+ should have made great progress in mopping and cleaning.

In terms of movement, in order to cope with the plane with slight height difference and the escape from different corners, the S7+ is also equipped with a main wheel with excellent elasticity and a multi-angle front steering wheel to ensure that the host can maintain smooth when moving and sweeping.

This time, the main brush of the S7+ itself has been replaced by a rubber form that is less prone to entanglement of hair and can more thoroughly scrape the dirt on the ground. The main brush is also made of soft rubber, with a ridgeline design. Improve the grounding performance to have a better overall cleaning effect. The way to remove and clean is as simple as usual. Press the button on the outer frame of the main brush to easily remove the main brush, while the corner side brushes are Single-sided design with five claws.

As for the accessories, in fact, the robot body also comes with a basic charging stand and power cord. However, since the S7+ is equipped with a dust collector with a recharge function, the functions and uses are basically completely duplicated, so I will not introduce them here.

Finally came to the highlight of our review: the unpacking of the dust collector. After all, the S7+ is one of the few sweeping and dragging robot models on the market that is equipped with sweeping, dragging, and dust collecting functions at the same time. The editor mentioned at the beginning that the S7+ The reason why it is called S7+ is because it is equipped with this dust collector, and the dust collector is currently only sold in the form of S7+ set. The front of the outer box of the S7+ dust collector highlights the dust collector itself with a pure white home environment. At the same time, the main features of the dust collector and the TUV Rheinland certification mark are printed on the front. The back of the outer box is printed with a simple picture accompanied by text, an overview The structure and operation of the dust collector.

The S7+ box is divided into two layers. As soon as we unpack the box, we can see the dust collector base on the first layer and a quick start guide. As for the included dust bag, it is placed under the base. The second layer has the body of the dust collector, the special dust box for the dust collector, the dust bag mounting bracket and the power cord. By the way, the red cyclone structure was originally installed in the dust collector body.

Before starting to use the dust collector, the user needs to assemble the base and the body. We can see the supplied screwdriver, the screws to be installed and the information label of the dust collector from the back of the base. Maybe many people think that it needs to be assembled with a screwdriver, which should be very troublesome, but to be honest, the original design in this regard is really thoughtful. They set a simple screwdriver slot directly on the base. And for each position where the user needs to install the screw (the screw is already on the base), the pattern of the screwdriver is engraved and there are sequential numbers. Although it still takes a little time and effort to turn and lock, but these are humanized. The detailed configuration allows the editor who has not even read the manual to quickly understand how to combine the base with the body.

Although the screw installation and rotation are quite easy, but the brand also reminds that unless the position of the screw is specified, it is necessary to avoid random rotation and thus affect the dust collector. However, because the transparent duct is the channel for the suction flow between the main unit and the dust collector, it may accumulate dirt after long-term use. The user can turn the surrounding screws to remove the duct for cleaning.

After unpacking and assembling, let’s take a look directly at the front of the dust collector. The appearance of the dust collector is dominated by a simple design with a pure white background. In the center is the indicator for the status of the dust collector, and the words “Roborock” are printed on the side. The dust collector itself is not small in size. According to official information, the size is 457 X 314 X 383mm (length X width X height). In addition, there are four oval black anti-skid pads around the bottom to ensure the stability of the dust collector.

The top of the dust collector also follows the simple design style of the S7+. The left side is the filter system of the dust collector, and the right side of the brand's logo pattern is the location of the dust collector. There is a red cyclone structure installed in the cylinder at the beginning. , the sticker on the drum is a graphic description of dumping garbage and cleaning and maintenance.

In order to avoid secondary pollution caused by dust collection, the left side of the dust collection seat is equipped with a filter system composed of cloth material and an H13 grade HEPA filter. According to official tests, the system can intercept dirt with a minimum of 0.3 microns. In addition to dirt and fine dust, it also achieves a 99.99% filtration performance to ensure that users will not inhale the leaked dirty air due to dust collection. Also because of this complete filter design, the dust collector of the S7+ is the only dust collector system that has been certified by TUV Rheinland, allergy-friendly and no suction loss, allowing users to obtain a convenient and clean environment, as well as There is no need to worry about the problem of dirty leakage of dust collection.

Wanting to reduce the household trouble of frequent dumping of garbage by users is the opportunity to promote the birth of the dust collection seat of the sweeping robot, so the larger the dust collection capacity is, the better. It can be used for up to 3 months before the garbage in the tub needs to be removed. This time, it provides users with two forms of garbage disposal at the same time, which can be said to be a highlight of the S7+ dust collector. The brand provides a total of two options: a multi-cone cyclone without consumables and a replaceable dust bag. Users can choose between According to the situation or preference of your own home, choose the form of garbage disposal that suits you, and use multi-cone cyclone or a combination of dust bag and dust collector.

In addition to the multi-cone cyclone with or without consumables, the Roborock S7+ dust collector also has a replaceable dust bag form for users to choose. Users who don’t like the dust collector should be quite happy. The dust bag is specially designed to be pulled and closed to ensure that the inhaled dirt will not be exposed along the gap when dumping the garbage. The closed structure part is made of a material similar to thick kraft paper. The editor repeatedly pulled it several times. I found that it has unexpectedly good durability, but considering the humid environment in Taiwan, if it can be changed to a more durable plastic sheet in the future, the durability of the dust bag may be further improved.

The main reason for the large size of the S7+ dust collector is that the robot itself has a certain size. In order for the robot to be able to recharge the dust stably, the base must not be too small, so the base of the S7+ dust collector is quite wide. The black block in the center of the dust collector is the sensing area that helps the host detect the dust collector, and the long hole in the center of the base is the dust collector connecting the dust collector to the robot.

In order to make it easier for consumers to get familiar with the operation of the host, the brand's R&D team can say that they have invested a lot of effort in the operation and installation of the S7+ dust collector, although it may be necessary to ensure the filtering effect and provide more Diverse dust collection options are a little more complicated in other aspects, but the included accessories only have power cords, instruction manuals, and getting started guides. Just make sure that the accessories of the dust collector are fully installed, and after connecting the power supply and the host, , the user can start using the dust collector.

In addition, when the user does not install the dust collector, the indicator light of the dust seat will turn red to remind the user. However, during this time, the robot can still perform the normal recharging action. After the dust collector is installed , the indicator light will turn back to the usual white light.

In order to allow users to fully liberate the functions of the host, the S7+, like most robots, can perform more subtle settings and more diverse operations on the dedicated app.

The user only needs to press and hold the partial cleaning and recharge buttons for about 3 seconds at the same time, and the host can enter a detectable state. After confirming the network-related information, the pairing with the mobile device can be quickly completed. The page will also display the map screen that has been sensed so far and a simple guide for each operation, which is convenient for users to get started.

The overall page design of the S7+ is basically the same as that of the Xiaomi system. Whether it is the settings of the voice, the robot itself or the map, users can make fine adjustments on the app. You can also choose the mode that suits you on the top.

In addition to the autonomous perception of movement by the robot, users can also remotely control the buttons or joystick mode. In order to adapt to the cleaning needs of different spaces, this map also has the function of setting virtual walls and restricted areas.

In terms of cleaning modes, in order to meet the sweeping and mopping requirements of various space environments, the S7+ provides a total of 4 sweeping suctions: quiet, standard, strong, and MAX, and 3 mopping intensities: gentle, daily, and strong. Users can even separate Adjust the force of sweeping and mopping, or just sweep without mopping. In addition, this time there is a setting called fine mopping. After starting, in addition to focusing on the mopping function (stop vacuuming), the mopping action will also be performed in a finer route than usual.

In the app, not only S7+ can have various functions and operations, but users can also obtain detailed maintenance information, such as cleaning records and whether accessories such as filters and main brushes need to be replaced or cleaned, and records of problems with the host It can also be uploaded directly to the brand's customer service mailbox.

Although the S7+ has achieved good results in the improvement of the main brush this time, compared with the fuselage, the length of the main brush is a little short, and the side brush is a little too long, which sometimes causes some dirt to be missed. With the help of the radio navigation system, the S7+ can clean back and forth or increase the cleaning intensity for the dirty places on the ground, ensuring that different planes can still be cleaned. In addition, thanks to the round body of the main unit and the various sensors, the S7+ has excellent ability to get rid of dead spots and clean edges and corners. As long as the space is not too narrow, users can get a satisfactory cleaning experience.

In the app corresponding to the S7+, a total of 4 sweeping modes are provided: quiet, standard, powerful and MAX for users to choose freely. Although many users prefer to use the sweeping robot when the space is empty, there are also situations like using it when sleeping. Therefore, if the cleaning volume can be as low as possible, of course, the better. Audio recordings were made. The volume of the quiet mode can be maintained below 60 decibels, and it will only exceed a little when the carpet is pressurized. Although it cannot be said to be quiet, the overall volume performance is considered to be quiet. The volume performance of the standard mode and the quiet mode is very close, but when the surface is cleaned, there will be a volume of nearly 60 decibels. I think the difference is not big.

The volume of the power mode is significantly increased, and the volume will reach about 65 decibels when encountering a carpet or a dirty area. As for the highest intensity in MAX mode, the whole process is cleaned with the strongest suction. According to actual measurements, the maximum volume will reach about 70 decibels.

The effect of the mopping function can be said to be the part that can truly reflect the strength of the sweeping and mopping robot. The mopping function is also a part that major brands have been continuously improving. Of course, there are also brands that think that sweeping and mopping should be separated to fully demonstrate the reality of sweeping and mopping. Effect. In the early days, some relatively entry-level sweeping and mopping robots were ridiculed because the mopping cloth itself could not exert additional force, and it only wet the floor. Later, functions such as smart water tank and pressure mopping gradually appeared, and the mopping function is relatively complete. . This time, the S7+ not only improves the power of pressurized mopping, but also is equipped with a new sonic mopping technology, coupled with the convenient mechanism of automatically lifting the carpet, so that it not only wets the floor, but actually It has obvious effects. Of course, it is still difficult to directly mop the dirt such as oil or soy sauce, but it is still enough for general daily mopping.

This time, the S7+ has a lifting structure at the bottom of the robot, allowing the mop to have a lifting space of about 5mm, except that when the robot passes the carpet surface (need to turn on the avoid carpet/adaptive carpet function in the APP), the mop will automatically rise and stop. In addition to vibrating out of water, the mop will also rise during recharging, thereby preventing the robot from getting the dust collector or charging stand wet.

Finally, let's talk about the dust collector, which echoes the circular body of the robot. The dust collector of the S7+ is also relatively large, measuring 457 X 314 X 383mm (length X width X height), but because of this, let The dust collecting seat has a more complete configuration. Not only does the seat have an excellent filtration system, but the capacity of the dust collecting cylinder has also been increased (the capacity of the dust collecting cylinder is 1.5L), and it supports two types of dust collection, cyclone and dust bag. Due to the larger size of the dust collection seat, the suction port duct can have a larger space configuration, and with the non-attenuated dust collection suction power, even a single dust collection can have a good effect.

Before collecting dust, I photographed the state of the dust box that had just been cleaned. The surface looks very clean. It can be seen that the dust box is well sealed, and the box is filled with test cookie crumbs and small candies. Of course, there are still a lot of original hair and lint on the floor, but after the complete dust collection process, the inside of the dust box becomes very clean, there is almost no visible dirt, and only a very small amount of the gap between the box lids remains. According to the repeated tests of the editor, even if the dust box is almost full and contains large particles of dirt, the powerful suction of the dust seat can still complete the task of cleaning the dust box.

In addition, I would like to remind everyone that before using the dust collector, be sure to confirm whether the main brush on the host is properly installed, otherwise there may be cases where the cyclone structure and dust bag accessories cannot be used to collect dust normally.

To talk about the part of the S7+ dust collector that can be improved, I think it is the volume of the dust collector. According to the editor's actual measurement, the volume performance will probably fall between 75 and 78 decibels, although the whole process is only more than 20 decibels. Seconds, but it is quite loud during use, if users use the dust collection function at night, they may need to pay a little attention. However, there is no doubt that the S7+ dust collector has strong suction power. The outstanding dust collection performance is believed to effectively improve the convenience of cleaning at home.

Roborock Technology has always been specializing in the production and research and development of cleaning appliances. S7+ can be said to be a disgusting product launched by the brand based on the accumulation of experience over the past few years and feedback from consumers. Whether it is sweeping or mopping performance, both efficiency and cleanliness can be taken into account. With the network system that has reached maturity in previous generations, users can also use exclusive applications to perform various user-friendly operation settings. In terms of dust collectors, in addition to the large operating volume and size, the editor will definitely give a very high evaluation. If you have enough space in your home, even if there is a price difference of nearly 10,000 yuan compared with the S7 that only has a simple robot, I would still highly recommend choosing the S7+ that goes with the console. To sum up, S7+ not only has obvious progress at all levels, but also has more comprehensive and complete functional control, and continues to maintain the brand's cost-effective features. As an electrical appliance that can greatly reduce the cleaning burden at home, it is naturally worth considering. !
