As a cleaning tool for lazy people, the sweeping robot can be said to be one of the appliances that can enhance the happiness of life. After the technological advancement from vSLAM visual navigation to LDS lidar navigation, the automation of sweeping robots is getting higher and higher. The sweeping and dragging robots look the same, but the sweeping and dragging levels are very different, and the space for technological iteration is very large.
Today we are introducing Midea’s flagship M7 Pro sweeper and drag machine. It has an eye-catching high-frequency vibration mopping function and a super suction power of 4000Pa. Is the real performance of the M7 Pro as strong as it is advertised? Now the machine has come to Tookfun’s hands. After a round of experience, let’s first tell everyone the experience and feeling conclusion of M7 Pro performance. The following is the specific evaluation process.
Advantage:
- The high-frequency vibration mopping effect is remarkable, and it can get rid of stubborn stains.
- Excellent silent performance. Even in the most high-end vacuum, the noise is no more than 55dB.
- 4000Pa large suction. The fine particles in the carpet can be removed.
Disadvantages:
- The capacity of the high-frequency vibration water tank is slightly smaller.
Appearance details
In addition to the main unit, Midea M7 Pro also has two side brushes, a normal mop and a spare HEPA filter. The high-frequency vibration mopping component and the elastic mop are individually packaged in boxes. The remaining floor brushes and ordinary mopping water tanks and dust boxes are all pre-installed on the machine. A spare HEPA filter is included with the box, which not only saves the user’s cost, but also can be used for alternate cleaning.
The volume of the ordinary mop water tank is 220mL. The mop board and the water tank are designed to be detachable, which can be easily removed and cleaned.
Since the vibrating mop assembly uses the mop plate as a vibrating part, it cannot be disassembled from the water tank, and the capacity is slightly reduced to 200 mL. However, it is still enough to complete a deep cleaning of the medium-sized apartment. The vibrating elastic mop is tightly attached to the moving parts by means of Velcro. Due to the need for high-frequency vibration under high pressure, the bonding strength is quite large. It needs more force when tearing off and cleaning.
The mop is divided into two parts, and the middle is connected by an elastic structure to ensure that the mop can still be firmly connected for long-term vibration.
The dust box of the M7 Pro has a capacity of 450mL. It adopts a three-layer dust filter design, and there is a layer of sponge between the primary nylon mesh and the HEPA filter to filter fine particles, which can effectively extend the life of the HEPA filter. The dust box adopts a one-key opening method, and you can even dump dust with one hand. Moreover, there is no dead corner during the dumping process, and it is easy to flush with water.
The overall style of the main body is closer to that of the previous generation M7. The biggest difference is that the top of the LDS radar module adopts a metal-like concentric circle border, which has a golden but not dazzling luster under the light reflection, which fully reflects the high-end positioning of the M7 Pro and can also be well integrated into the home environment.
Two side brushes can be installed at the bottom of the M7 Pro. This brand new left and right side brush is relatively homeopathic design, which can effectively increase the coverage area and dust gathering efficiency. The middle V-shaped roller brush is a floating structure, which can penetrate into the floor, brick joint slide rail and other difficult-to-clean places. Coupled with the larger “suspension” height of the second-generation BIIR non-slip drive wheels, the M7 Pro’s obstacle crossing ability is up to 2cm, and the whole house can be cleaned unimpeded.
The V-shaped roller brush is easy to disassemble and clean. If there is tangled hair, you can easily cut it off with the included blade.
Perception
Due to the LDS laser navigation system and the NaviPolaris 2.0 path planning program, the M7 Pro’s map creation speed is very fast in actual work, and the path selection can also be said to be completed in an instant.
M7 Pro has 30 sets of smart sensors throughout the body, providing functions including cliff detection and obstacle detection. Reflected in the test is the ability to avoid obstacles and escape difficulties. It is difficult to be stuck in a small area; when encountering obstacles, after one or two collision “tests”, the route will be changed cleanly. In short, there is no time wasting in complex areas such as chair legs.
The sensor of M7 Pro can also automatically recognize the carpet, intelligently pressurize, and enhance suction; the intelligent electronically controlled water tank, evenly discharges water, three-level adjustment, so that the mop maintains the proper humidity.
Intelligent control
The robot sweeping cannot achieve intelligent cleaning without APP. The M7 Pro’s networking process has been quite mature and simple. Download and open MSmartLife on your mobile phone. When the sweeper is turned on, you can discover new devices and add them smoothly.
After the device is added, click the sweeper card to enter the management interface, and the main interface functions are clear at a glance. The most commonly used functions such as map, power, suction, and water volume can be operated with one button. After scanning the whole house map, you can perform map management, and you can set room cleaning, room naming, zone cleaning, and regional deep cleaning. You can also set up virtual walls and restricted areas for sweeping and mopping, as well as continuous sweeping at break points and floor sweeping.
The management menu in the upper right corner is mainly for low-frequency settings such as vibration switch and viewing consumable life. Vibration mopping can choose efficient mopping or fine mopping. The latter’s bow-shaped route is more dense, but there is a risk of slipping. It is recommended to use it on the floor or non-glossy ground material.
Based on the open platform Midea, M7 Pro can not only perform rich self-management, but also link with other devices and sensors on the platform. For example, setting up the condition to schedule cleaning, or the smart door lock and the human sensor linkage sweeper, etc. Of course, due to time constraints, we will not start one by one here.
Various tests
Cleaning test
Before the start of the test, Tookfun needs to briefly sort out the unique functional configuration of Midea M7 Pro: LDS laser navigation system and NaviPolaris 2.0 path planning, HCM fusion control technology, cleaning efficiency increased by 30%; with a strong suction of 4000 Pa, up to 93 % Of ground dust removal efficiency, leading similar products on the market; equipped with high-frequency 500 times/min vibration mopping components, which can imitate the effect of mopping the floor.
Aiming at the three main performance dimensions of sweeping and dragging robots: path planning, suction and mopping. M7 Pro has its own unique technical blessing. Of course, the most noticeable thing here is the high-frequency vibration mopping function, which is similar to the repeated wiping of an electric toothbrush. It is perpendicular to the direction of the sweeping and mopping machine, which is equivalent to adding a cleaning dimension that does not exist in manual mopping. So we start with the mopping test to see if the M7 Pro can have outstanding results.
Mop
After half an hour of water immersion experiment, it was found that the water tank did not seep to the direction of the mop, so long-term use with the mop will not soak the floor.
Since Midea M7 Pro is equipped with a unique high-frequency vibration mopping component, ordinary mopping water tanks and mopping cloths will not be tested this time. The test of ordinary difficulty obviously can’t reflect the advantages of high-frequency vibration mopping, so we went directly to the high difficulty: a cup of milk, a cup of coffee, and black sesame paste containing compound grain powder, all dried until semi-dry (drying The later test increases the difficulty, but it is also more in line with the actual use scenario).
The first two are good to say. After the solid sesame paste + high-viscosity starch is dried, it is not easy to pick it off. It can be said that this degree of stain has basically simulated the worst floor environment in the home.
In the actual mopping performance, the high-frequency vibration of the M7 Pro can be cleaned up and down basically after milk and coffee, and the sesame paste is a little indifferent. So we adjusted the water output to the highest level, and the mop was fully soaked. The hard sesame paste also gradually began to dissolve and loosen, and after three or four rounds, it was completely dried by the M7 Pro. The high-frequency vibration mop has a strong absorption capacity. After being completely mopped, there is no dripping of sewage.
Sweep the floor
Still directly adopting the “hell mode”: the light and small quinoa is easily affected by airflow and side brushing; potato starch with a smaller granularity can sink deeper into the low-carbon fiber and separate the dust from the vacuum cleaner. The ability and HEPA filter is a serious test. Both are sprinkled on the carpet.
Again, the flagship configuration still shows its due strength. Although the quinoa particles bounced slightly after being swept by the side brush, they were not far away, and were soon covered by a larger area of sweeping, which basically achieved a one-time removal. The starch area seems to be ineffective for the first time, but in fact, the sweeper has already sucked up 80% of the starch on the surface, leaking out the true color of the carpet in a large area.
After the third cleaning, after passing through the contaminated area 7-8 times, the M7 Pro “fixed” the starch in the carpet fiber gully. This comparative result is quite good for a sweeper with an overall power consumption of only 55w.
It is worth mentioning that the noise performance of the Midea M7 Pro is quite good. In the case of using the highest powerful gear suction throughout the whole process, the noise value measured at a distance of about 1m from the sweeper is about 55dB.
The actual sense of hearing is much lower than that of handheld vacuum cleaners and similar sweeping robots, and it belongs to the kind of dull noise that is biased towards low and medium frequencies and does not affect normal speech in the room. This is due to the triple noise reduction design of the M7 Pro’s air outlet silencer, fan room vibration isolation and motor shock absorption.
Endurance test
M7 Pro has superb battery life, 5200mAh high-capacity lithium battery. The working time can last 3 hours under standard suction. Although the data in an ideal state is not universal, don’t forget that M7 Pro also integrates a lot of sensors and a powerful main control chip. Every step of the sweeper requires a lot of perception and calculation.
In our test, the most power-hungry is undoubtedly the powerful gear sweeping and high-frequency vibration mopping. After many times of the most high-end suction and mopping in the test site of about 30 square meters, the power grid of the M7 Pro shows a drop of about one-third (the main interface of the APP does not give a percentage of the power, which is hoped later Can be improved through software upgrades). At this rate, it is no problem to clean up a 90-square-meter apartment with high intensity. If it is a standard-intensity cleaning that is carried out every day, large-scale split-layer or stacking can also be easily handled.
Concluding remarks
From the most basic sweeping and towing efficiency test, the Midea M7 Pro sweeping and mopping integrated machine first has the ability to mopping surpassing most similar products, and the cleaning efficiency is comparable to that of a dedicated mopping machine; the sweeping performance also reflects the ultra-high 4000Pa The level of vacuum.
It should be understood that the use scene of the sweeping and mopping machine is not a one-time cleaning with someone present, but multiple automatic cleanings automatically set according to idle time. Therefore, under daily conditions, M7 Pro can be said to be able to cope with dust and stains on almost all floor materials. Do not do it again, this is the long term of the sweeping and dragging robot, and it also greatly expands the capabilities of the M7 Pro. It can be regarded as a “mature” robot.
