There is a very typical case of the so-called scientific and technological progress liberating people’s hands, that is, the emergence of sweeping and dragging robots, which can greatly reduce people’s housework cleaning work.
Nowadays, many people have sweeping robots in their homes. Although it does bring convenience to people, it is inevitable that people still need to “hands in”. But with the advancement of technology, sweeping robots can become more and more perfect, and they can do more and more. It is not a dream to complete the cleaning work completely independently.
For example, today, the new Roborock sweeping and dragging robot T7S Plus launched by Roborock Technology is a product that has taken a step forward in all aspects. At present, IGeekphone has also got this new product of sweeping and dragging robot. It has to be said that compared with the previous T7 Pro, this sweeping and dragging robot has been upgraded and improved in many aspects. Let’s take a look at it through the evaluation together with IGeekphone.
Get the Roborock T7S Plus sweeping and dragging robot. At first glance, you won’t think it is too different from the previous T7 Pro. Indeed, the overall appearance of the T7S Plus continues the design language of the previous generation. It is still a flat round body. The raised laser ranging and pressure sensor on the top are also round, and there are a few undulating ripples around it. The texture is a bit like the waveform of electromagnetic waves, and the details are still very elegant.
On the top of the fuselage, there is a faint roborock logo and three buttons for recharging, power supply and partial cleaning. The overall vision is simple and elegant.
The top cover of the sweeping robot can be lifted, and the surface is still white after it is lifted. You can see the dust box, Wi-Fi indicator and reset button. Roborock is also printed on the glossy glass next to the dust box, maintaining a simple and orderly design style.
The T7S Plus obtained by IGeekphone is a marble white colour. Except for the black bottom and the sensor part, the rest is clean and bright white. The black and white colour system brings a visual quality to the whole body. sense.
On the side of the Roborock, there are Reactive 3D obstacle avoidance sensors, wall sensors, water tanks, and air outlets. The components are still more complicated, but not messy. In particular, the red text “Reactive 3D” next to the obstacle avoidance sensor adds a sense of design on the side and looks very advanced.
Looking at the bottom of the T7S Plus, the content here is more complicated. From the outside to the inside, there are cliff sensors, side brushes, universal wheels, carpet recognition sensors, charging contacts, main wheels, soft rubber main brushes, and soft rubber main brushes. Brush cover and so on. Of course, since we hardly look at the bottom of the sweeping and dragging robot, this will not affect the design of the T7S Plus.
Looking at it as a whole, the Roborock T7S Plus has two feelings for the IGeekphone. One is designed and the other is excellent workmanship. Due to the particularity of the sweeping robot product, there are bound to be many sensors, buttons, brushes and other elements on the surface of the fuselage. The T7S Plus arranges these elements well through the design and integrates them into the whole product. The workmanship of T7S Plus can meet the needs of most users in terms of appearance.
An important feature of the Roborock T7S Plus is that it supports automatic dust collection and a charging stand.IGeekphone also got a black dust collection and charging stand. The charging base is larger than the trash can commonly used in the home and is composed of a dust collecting base and a dust collecting bucket. The dust collecting bucket can be taken out by hand for easy cleaning.
The design of the automatic dust collection charging stand is quite sophisticated. The two buckets stand side by side, especially the air outlet on the top of the dust collection stand has a sunken grid design, which looks a lot like the cooling vent on the top of the Apple MacPro trash can, Very technological sense.
The dust collecting and charging stand is an important function upgrade for the sweeping and dragging robot T7S Plus, which can bring a lot of convenience to the user experience, which we will introduce in detail below.
Experience of cleaning function
Attentive friends must have discovered that this time the product positioning of the Roborock T7S Plus has been upgraded to a “sweeping and dragging robot” instead of the original sweeping robot. This is because the T7S series products have undergone a major upgrade for the mopping function this time. , The sweeping and mopping performance is comprehensively improved.
So what upgrades does this sweeping and mopping robot have in the mopping function?
The first thing to say is that Rock T7S Plus is the world’s first lifting mop + vibration wiping + electronically controlled water discharge technology. It is the only floor cleaning robot that has both sound wave vibration wiping and intelligent lifting and wiping systems. Let’s take a look at these two important upgrade functions one by one.
1. High-frequency sound wave vibration grounding system
At present, most sweepers on the market are equipped with vibration modules for mopping, but most of these products have low vibration frequency, high noise, easy to get stuck, and poor cleaning effect.
The Roborock sweeping and mopping robot T7S Plus is equipped with a high-performance brushless motor, which can drive the mop-up to 3000 times per minute of high-frequency vibration, disintegrating ground stains. The official said that the cleaning power is 4 times higher than that of the Rock S5 series.
Not only that, the Stone T7S Plus also uses a four-link independent suspension floating module design in the mop area, which not only greatly enhances the reliability, but also allows the mop to fit the ground more stably when floating, achieving an excellent floor scrubbing effect.
The mop support of the Roborock T7S Plus mop robot is also divided into a vibration area (vibrating stains) and a non-vibrating area (taking away stains) in two-zone tacit cooperation, which greatly increases the vibration frequency and controls noise.
In actual use, users can customize the individual floor wiping intensity and wiping mode for each room on the App side according to the dirt on the ground. There are 3 modes to choose from, namely: weak 1650 times/min 28Hz, medium 2300 times /Min 38Hz, strong 3000 times/min 50Hz.
In actual use, the mopping function of the IGeekphone T7S Plus cleans the coffee stains on the ground. When cleaning, the editor chooses the “fine mopping” mode, and it is matched with the zoned cleaning. You can see that T7S Plus’s mopping performance is really excellent, the original conspicuous coffee stains are thus eliminated.
And when mopping the floor, the noise of T7S Plus is not too big, which is roughly equivalent to the mid-range sound of a household electric fan, which will not cause discomfort.
Intelligent lifting and wiping system
In addition to sonic vibration, the Roborock T7S Plus has an intelligent lifting and wiping system. The combination of the two can be said to be the first in the industry.
The fully automatic lifting and wiping module have an exquisite structure. It uses a motor and a gearbox to drive pulleys and cables to achieve autonomous lifting. The lifting cables are made of 304 stainless steel thin steel ropes and have a bending life of more than 300,000 times. Tested, firm and reliable.
What is the specific use of this lifting and wiping module? The answer is the cleaning of the carpet.
Many families choose to lay carpets in the living room. In the past, when the sweeping robot touched the carpet, it would often get stuck because it could not recognize it well. And if it is not stuck, the sweeping robot will run over the carpet with a dirty mop and wheels, causing secondary pollution to the carpet, which is really a headache.
On the T7S Plus, Stone additionally introduced an ultrasonic carpet recognition technology, combined with the lifting and wiping system to solve this problem.
Ultrasonic recognition technology is to add an ultrasonic carpet recognition sensor to the bottom of the robot. The ultrasonic device judges the floor material through the inconsistency of ultrasonic echo on hard surfaces such as carpets and floor tiles, thereby identifying the carpet. At the same time, Shishi also introduced a self-developed “carpet recognition algorithm and strategy”, which allows T7S Plus to increase the accuracy of carpet recognition in a complex ground environment.
The factory default of sweeping and mopping robot is “adaptive carpet mode”, that is, after encountering a carpet during the sweeping and mopping process, it will automatically raise the mopping module to pressurize the carpet. This is mainly suitable for short-haired carpets (≤5mm). ) Or floor mat environment.
Users can also change their own carpet cleaning methods through the mobile app, including adaptive mode, carpet avoidance mode and carpet ignoring mode.
In actual use and testing, the editor found that after the stone T7S Plus recognizes the carpet, the carpet area will be shown on the map in the form of dashed shadows, and the “carpet area” is marked, so that everyone can see the location of the carpet more intuitively. Note that this mark is automatically marked by the system and does not need to be marked manually.
When the carpet is recognized, T7S Plus actively raises the mopping module to clean the carpet to prevent the carpet from being wetted and reduce the resistance to walking on the carpet.
If you start the carpet deep cleaning test on the mobile app at this time, T7S Plus will also clean up the dirt hidden in the carpet. For example, I sprinkled some coffee on the carpet. Under the deep cleaning of T7S Plus, the coffee powder All were swept away.
And if you choose to avoid the carpet mode, when the T7S Plus with the mop installed detects the carpet, it will actively avoid it to avoid cleaning the carpet area.
As can be seen from the figure below, when T7S Plus recognizes the carpet, there will be an obvious trial process. After the carpet is indeed the carpet, it will not be applied but will be cleaned along the edge of the carpet.
In addition to carpet cleaning, the automatic lifting and wiping module also brings stronger obstacle surpassing ability to the T7S Plus. Obstacles usually smaller than 2cm can be easily overcome. After the cleaning is completed, the floor wiping module will also be lifted during the charging process. Prevent the dirty mop from polluting the ground again.
During the test, an obstacle of about 2cm was placed on the T7S Plus walking route. When the T7S Plus passes this obstacle, it can indeed be turned over, and the floor scrubbing module can be seen to have an active lift at the moment of crossing it. Up the action.
AI structured light, more powerful navigation
The previous generation Roborock sweeping robot T7 Pro used AI binocular obstacle avoidance technology, giving T7 Pro an excellent performance in navigation and obstacle avoidance. This time, T7S Plus directly uses 3D structured light technology.
We know that the original depth camera of the iPhone uses 3D structured light technology, which can accurately measure the depth information of objects. It is relatively high-end technology. This time, Rock moved this technology to the sweeping and dragging robot T7S Plus. In short, it can achieve millimetre-level high-precision obstacle avoidance.
In fact, if only 3D structured light is used, it is not enough. Stone also integrates multi-sensor data such as LDS laser ranging, ultrasonic carpet recognition, and high-precision wall sensors on the T7S Plus. With AI algorithms, it can accurately identify the surrounding area. Objects, while avoiding accidental collision, or missed scanning due to excessive obstacle avoidance.
During a cleaning process, we observed the cleaning process of the T7S Plus. It can be seen that the T7S Plus can well avoid obstacles such as the photography light stand on the ground without knocking them down. At the same time, some unique table legs T7S Plus did not let go of the gap in the structure but tried to clean it in a circular route.
Thanks to the blessing of 3D structured light technology, T7S Plus can also measure the height of the surrounding environment, so as not to let yourself be caught by furniture such as sofas and beds.
It can be seen that when the T7S Plus enters a highly critical environment, the walking strategy will switch to a conservative mode to try to clean the sweepable environment as far as possible. When it is confirmed that it cannot be cleaned, it will avoid obstacles.
Stone automatic dust collection and charging stand
As we mentioned earlier, with the new stone automatic dust collection charging stand, T7S Plus can be more convenient to use. Let’s take a look at the experience of sweeping and dragging robots with automatic dust collection and charging stand.
The automatic dust collection charging stand is larger than the sweeping robot, but it is not troublesome to install. You only need to press the dust bucket and the base separately, and then tighten the screws at the bottom. It belongs to the Xiaobai style installation.
The biggest advantage of the dust collecting and charging stand is that it can automatically collect dust to prevent users from dumping dust and effectively reduce the frequency of cleaning the sweeper, so you don’t always have to think about whether the sweeping robot has cleaned it.
The principle that the stone automatic dust collecting and charging stand can realize dust collection is equipped with the “15 cone cyclone technology”, which throws dust into the dust bucket through strong centrifugal force. Compared with other cleaning appliances, the method of separating dust mainly by the filter, the stone is In addition to achieving more efficient separation, this technology can also effectively prevent the filter from being blocked by dust, which will cause the machine to fail to work and even affect the service life. This technology has also been certified by TÜV Rheinland without loss of suction.
When in use, when the Roborock T7S Plus sweeps and drags the robot to complete cleaning, it will immediately turn on the automatic dust collection after returning to the automatic dust collection charging station to prompt to start charging. When the dust is collected, the exhaust vent will quickly exhaust the air, and the dust bucket will make a relatively loud noise, but it will only last about 15 seconds, so it will not have much impact.
It should be noted that if you use a dust collecting and charging stand, the T7S Plus should also be replaced with a dust box dedicated to dust collection, and the side cover of the dust inlet on the right side of the dust box compartment should be opened, otherwise, the dust cannot be collected normally.
After the dust collection is over, IGeekphone opens the dust box of T7S Plus, you can see that the dust swept in during the cleaning process is basically concentrated in the dust bucket, there is only a little residue in the dust box, and the dust collection effect is still very good. of.
If the dust bucket is full after a long time of use, you need to dump the dust in the dust bucket manually. It is also very convenient when cleaning, just press the red button at the bottom, the bottom of the bucket will open, and then pour out the dust.
Of course, no matter how simple it is, you will inevitably encounter the problem of dust when you take out the garbage, which may still be a headache for people with allergies. Stone also takes this problem into consideration, so the design of antibacterial dust bags that can replace cyclone dust is introduced in the dust collection bucket to meet the needs of different people.
When using, you only need to remove the cyclone in the dust bucket according to the instructions, fix the dust bag on the bracket, and then put it into the dust bucket instead, so that when the dust is collected, the dust will be uniformly stored in the dust bag. To clean the dust bucket, you only need to remove the dust bag and throw it away.
Since the dust bag adopts a sliding dust bag mouth sealing design, there is no need to worry about dust leakage, and the material itself is also high-density composite antibacterial, the filter efficiency of the whole machine can be maintained at 99.97%, and there is no need to worry about a series of dust leakage and other problems. problem.
It is particularly worth mentioning that the capacity of the cyclone barrel is 1.5L, and the capacity of the replacement dust bag is 1.8L. Both have relatively large capacities. Normal use only needs to be cleaned once a month, which can be said to be very trouble-free.
In general, with the automatic dust collection and charging base, the convenience of using the Roborock T7S Plus can be improved, and the T7S Plus can complete the cleaning task more independently and completely.
Other user experience
In addition to the above-mentioned key function upgrades, the Roborock T7S Plus sweeping and dragging robot also continues many excellent features of the previous generation products. Here we also take a look.
The first thing I want to talk about is the improvement of the T7S Plus hardware detail, that is, the glue brush. This time the glue brush adopts a precision TPU design. The surface has a precision design of 5 long and 5 short, which can effectively ensure the wind pressure and dust removal effect. The design can effectively avoid the problem of hair entanglement, and the hair can be easily sucked into the dust box or slid into the hair storage bins at both ends of the main brush.
During the test, IGeekphone put some fine lines on the floor to simulate hair. It can be seen that these fine lines were swept away by T7S Plus. After scanning, the editor checked the rubber brush at the bottom, and the surface was not entangled with fine threads.
After collecting the dust, the editor found these fine lines in the dust bucket.
The Rotor Mop Robot T7S Plus has a fan speed of up to 20,000 rpm, which brings a suction power of up to 2500 Pa. In addition to hair, dirt such as cereal, sugar, dander, food residues and so on can be easily swept away.
In addition, like Stone’s previous products, T7S Plus also supports the functions of zoned cleaning, virtual wall setting, and where to sweep. If you only need to clean a certain part, or you don’t want T7S Plus to clean a certain part of the house, you can. Set up on the mobile app.
In addition, there are detailed map management functions, such as partitioning, editing, and marking the map where is the bedroom, where is the kitchen, where is the study, etc. These functions have been introduced in detail in many articles before, so I won’t be here. Go into details.
Also, after upgrading the latest firmware, the T7S Plus sweeping and mopping routes have different display methods on the App side. The mopping path has become a light white thick line pattern, which can be seen visually. Where did the T7S Plus scan and drag?
For the Roborock sweeping and dragging robot T7S Plus, there is another obvious change, that is, the special design of the light strip is added for the first time, using RGB three-colour common anode LED, which can change through the flow of blue, white, and orange lights to users Show the normal working status of the sweeping robot. If you need to turn off the light strip, click the three dots in the upper right corner of the homepage to select “Robot Settings”, and select to turn off “Status indicator light is on”.
Finally, the Roborock sweeping and dragging robot T7S Plus is equipped with a large 5200mAh battery. The official said it can last up to 2.5 hours in a single battery. During the test, IGeekphone used to clean continuously for about 20 minutes and consumes about 15% of the power, basically sticking to three and a half. There is nothing wrong with hours. In addition, T7S Plus also supports smart breakpoint continuous scanning, if you charge it for a while, you can continue scanning from where it ended last time.
Among many sweeping robot brands, Roborock sweeping robots have always been a relatively good brand in terms of overall product experience and price-friendliness. Especially in terms of the practicability and functionality of the sweeper itself, it attaches great importance to the user-friendly experience. And this time the Roborock sweeping and mopping robot T7S Plus can be said to be a further improvement of the excellent experience of the past products: sweeping-mopping-dust collection-cleaning-the next sweeping, such a closed-loop experience, obtained on T7S Plus Very well presented.
From the perspective of the product experience itself, the Roborock T7S Plus is as stable and excellent as ever, especially in terms of mopping and dust collection, which further enhances the practicality of T7S Plus. At the same time, considering its 2799 yuan The starting price of the new product, this sweeping and dragging robot is more worthwhile for most consumers.
Of course, if you have enough budget, IGeekphone also recommends that you buy it together with T7S Plus, which can make the robot cleaner more worry-free and trouble-free.
