Sweeper dismantling: battery performance articles
The invention of the ground robot has to be said to be the gospel of lazy people, and also a good helper for the housewives. The more busy people provide a quick, convenient and time-saving way to clean. The small household electrical appliance enterprises have had good independent research and development and production capacity in recent years. However, in the field of sweeping machines, we still see the imitation and plagiarism between products. Some products even changed only one trademark, and they turned into another one. There is also concern about cleaning ability and coverage. Some consumers have been hesitant to buy sweepers, worried that money will go out, but bought a toy. Aliandeb integrates six powerful brands on the market, including iRobot, Kovos, neato, LG, FMART and Dog, for a full range of video cross-evaluation, lasting one month, 10 tests, 12 comparisons, all-round display Sweeper performance provides the most reliable reference for consumers to purchase sweepers. This horizontal review is all presented in video format, bringing consumers the most intuitive experience. (Objective test parts include: cleaning rate, coverage, dust, climbing ability, off-road height, intelligent crossing, noise, edge cleaning ability, obstacle escape, and escape test)
Before the Sweeper Video Hengping was officially launched, we dismantled the Sweeper, mainly comparing its internal structural design and materials. We divided the disassembly into three parts: the battery, the brush design, and the size of the suction port. The comparison of these three aspects is mainly because these three points are important factors in determining whether the cleaning efficiency of the sweeping machine is high. This dismantling cross-evaluation is presented to you in the form of video, which allows you to clearly and intuitively see the internal structure of the fuselage and materials.
The cleaning power of the sweeping robot mainly comes from the rechargeable battery pack inside the machine. The batteries of most mainstream products are 14.4VNI-MH battery or 14.8V Lithium-Ion Battery, and the battery pack capacity ranges from 1500mAh to 3500mAh. The battery pack of the sweeper will directly determine the maximum battery life of the product, and indirectly determines the maximum cleaning area of ​​the product. So what is the difference between Lithium-Ion Battery and NI-MH battery? Why do some manufacturers prefer nickel-metal hydride batteries, while others prefer polymer lithium-ion batteries?
Let’s first talk about NI-MH battery. NI-MH battery has low environmental pollution and large capacity, but its volume is relatively large, which leads to heavy body of the sweeper. However, NI-MH has high stability and high security. One thing to note is that NI-MH battery has a certain memory effect. Although it is not as obvious as nickel-cadmium batteries, the memory effect is more obvious than Lithium-Ion Battery.

Lithium-Ion Battery is a new generation of liquid lithium battery, which greatly reduces the safety hazard of explosion of liquid lithium ion battery, has higher energy density, and has small volume, light weight and no memory effect. However, it should be noted that although the polymer lithium ion battery is more stable and overcharged, it will not explode like a lithium battery. However, overcharging will still cause swelling and safety hazards.

Some consumers are always worried about the explosion of the battery, in fact, whether it is NI-MH battery or Lithium-Ion Battery
There may be security risks after overcharging. Consumers should not overcharge when using the product, and use the product normally, whether it is a polymer lithium battery or a nickel hydrogen battery, it is a good choice. Nickel-metal hydride batteries have good stability and high safety. The polymer lithium battery is small in size, light in weight, and has no memory effect. The table below lists the main differences between NI-MH battery and Lithium-Ion Battery.

Lithium-Ion Battery
Advantages: small size, light weight, no memory effect, with the use of charge, low self-discharge rate.
Disadvantages: Safety and stability are not as good as nickel-metal hydride batteries, and the price is expensive.
NiMH batteries
Advantages: high safety, good stability and low price.
Disadvantages: large, heavy, memory effect, fast charging, high self-discharge rate.
(The so-called memory effect is a simple example, such as releasing 80% of the power and then fully charging, the battery can only release 80% of the power, instead of 100% of the full charge).

Editor’s summary:
Consumers have two choices for battery selection: life time and safety.
At the same capacity, due to the large size of the NI-MH battery, it must be heavier, which increases the weight of the body. The sweeping machine is dragging a heavy NiMH battery pack during the cleaning process, which will inevitably reduce its battery life, short battery life, and indirectly affect the cleaning area. On the contrary, due to the light weight of the polymer lithium-ion battery, the battery life is slightly better under the same capacity. Secondly, the question about the length of life is also affected by the ground material. The rougher the ground, the greater the friction and the greater the power consumption. For example, cleaning the space of the same area, the battery life on the carpet is shorter than the battery life on the floor.
As a household cleaning product, the sweeping robot was originally designed to liberate the hands of lazy people. Without the need for manual cleaning, the sweeping machine can complete the fully automatic process from cleaning to recharging. However, the sweeper is a special household appliance. Most of the time we make an appointment. The sweeper will clean it at the scheduled time. It is an unattended product, so its charging safety and stability must be considered. If overcharging occurs, it is likely to cause an accident such as a fire. Although the technical security of lithium battery has been developed more maturely, the probability of occurrence is very small, but at this point, the stability and security of NI-MH battery is slightly better.

In summary:
The current NiMH battery packs installed in the sweeper are basically above 2500mAh, enough to clean the room of about 100m2. The sweeper is a special intelligent product, not only considering its cleaning ability, safety and stability. It should be taken into account. In order to sell some, some manufacturers advertised their own use of “lithium”. However, in actual use, for a product such as a sweeping robot, in the environment of a high-efficiency discharge platform of a vacuum cleaner motor, the lithium electrode is prone to bulging for a long time. Lithium batteries are suitable for use in notebooks, but may not be suitable for sweepers, which is why nickel-hydrogen batteries are used in 95% of the industry.
