Why consider a cordless vacuum cleaner?

Traditional vacuum cleaners have large suction power and are still essential appliances in many households. However, they are relatively heavy and the power cord is inconvenient to drag around. Although robot vacuum cleaners can clean autonomously, their cleaning performance is still insufficient, so cordless vacuum cleaners are becoming more and more popular.

Easy to use and lightweight, it is very convenient for daily cleaning of debris, hair, dust, stairs, and even the interior of the car. But don't expect it to thoroughly clean all your rooms at once. Most cordless vacuum cleaners have a limited operating time after a single charge, and need to be charged after a period of use.

When to use a cordless vacuum cleaner

Before you buy, think about your main purpose of buying a cordless vacuum cleaner? Cleaning the floor after a meal, or vacuuming in the bedroom, or cleaning pet hair on carpets and sofas, because the market has a wide range of functions and excellent options for various performances. Not much.

If you just want to simply vacuum or deal with pet hair, then many models can do it without having to buy a high-end product. However, if it is to remove agglomerated, sticky food, such as rice balls, food mash, etc., then please choose a vacuum cleaner with strong suction and suitable straw thickness. If it is to remove very light debris, the opposite is true. The rotating brush will push the debris away instead of sucking it in. So please choose the model that suits your main purpose.

Cordless vacuum cleaners and traditional vacuum cleaners are each suitable for the following situations:

How to choose a good cordless vacuum cleaner

Although cordless vacuum cleaners are not as powerful as traditional vacuum cleaners, their efficacy is quite different. The power given by the manufacturer is more a reminder of the efficiency of the motor than the cleaning efficiency of the vacuum cleaner itself. Airflow and dust brush rotation consume power. Some models can always maintain the same suction power during operation, while the suction power of some models will gradually decrease. Therefore, unless you try it, it is difficult to judge the strength of suction from the parameters. More and more models use filter systems to prevent dust from clogging the filter, but its disadvantage is that it occupies an already limited dust collection space.

Maneuverability

Easy handling is the main buying point of a cordless vacuum cleaner, because it must be light and easy to operate. According to the appearance, there are three common types:

1-Rod type

The motor and dust collector are located in the middle of the handle, and most cordless vacuum cleaners are in this shape. It can be stored vertically; the dust box is also larger, but the whole is heavier, because the weight is concentrated in the middle and lower parts, it is relatively laborious to use.

2-Tube type

The motor of this cordless vacuum cleaner is located at the top of the handle, and the other end of the handle is the dust brush. This type of vacuum cleaner is lighter and easier to handle, but the dust box has a small capacity.

3-Two in one

The combination of the above two types: a combination of a rod-type vacuum cleaner and a detachable hand-held vacuum cleaner. The dust collector is also smaller, lighter in weight, and easy to handle.

Ease of use is also affected by ergonomics. The ring-shaped handle is easier to grasp; the independent switch saves you from having to press the button during the entire cleaning process; common information such as battery level is easier to read on some models. These are all you need to pay attention to when buying.

Battery

Nowadays, most cordless vacuum cleaners use the same lithium batteries as mobile phones and electric cars. They last longer and are more durable. There are also entry-level models that use Ni-MH batteries, which require a long time to charge. So it is better to buy a vacuum cleaner with lithium batteries, but they are also more expensive. In addition, there are very few vacuum cleaners with removable batteries.

Autonomous battery life

The battery life claimed by manufacturers is often low-intensity settings. Once the maximum suction power is set, this time may be shortened by 2-3 times.

The suction setting allows you to adjust the intensity according to your needs to remove easy-to-clean dust, which can save energy. Most vacuum cleaners have 2-3 settings. The sliding button is very practical, because it allows you to clearly see the gear (Figure 1), but different vacuum cleaners have different designs.

It is practical to know whether the power is sufficient during the vacuuming process. The cordless vacuum cleaner has a battery indicator. Usually, the green light indicates that the battery is sufficient, and it turns red when the battery is low. Some models use multiple diode lamps, which will turn off one by one as the power drops.

Dust brush

The main dust brush largely determines the dust collection performance. Use nylon, polyester or carbon fiber to absorb dust and dust, and it will automatically rotate when the power is turned on. Some models of dust brushes can be disabled, which is useful when removing very light dust such as paper crumbs and bread crumbs to prevent the dust from being blown away. However, there are very few vacuum cleaners with this function.

The size of the dust brush also has an influence, the wider the brush, the faster the cleaning. The size of the dust brush is as large as 30 cm, and the size is only 18 cm. In addition, the side brushes also affect the cleaning effect. They are mainly used to clean the dust on the corners and edges. Some vacuum cleaners have weak side brushes. If so, you can use nozzles instead.

Annex

The vacuum cleaner has a variety of accessories to choose from. First of all, let's take a look at the accessories that come with the machine. A main dust brush cannot meet all cleaning needs. The long gap suction nozzle can remove dust from the edges and corners. The sofa brush can clean woven fabrics. The small turbo brush is similar to the main brush, but smaller to facilitate cleaning of car seats.

Noise

Although some very powerful traditional vacuum cleaners can make the noise very low, don't expect cordless vacuum cleaners to be very quiet. It is difficult for them to achieve good sound insulation, and the sound of electric motors is inherently noisy. Fortunately, the normal use of cordless vacuum cleaners does not take too long, and it can be tolerated.

How do we test a cordless vacuum cleaner

A good hand-held cordless vacuum cleaner should have strong suction power, easy to use, and make daily cleaning at home easy. We have tested and scored nearly 60 cordless vacuum cleaners in our European laboratory. How is the test performed?

The tested samples were purchased anonymously from the market, and then carried out in an independent laboratory with controlled humidity and temperature. The tests are based on relevant European and international standards. The dust box is emptied and cleaned before each test, the battery is fully charged, and the maximum suction setting is used.

Suction

Hard floor

Vacuum dust on hard floors: Place precise amounts of metal gravel on the floor tiles and spread them on an area of ​​70 square centimeters on average. Repeat the suction three times, and then measure the amount of metal grit collected.

Suction crumbs on hard ground: Sprinkle 35 grams of crumbs on the same ground in an area of ​​70 square centimeters, and measure after vacuuming with a vacuum cleaner.

Wood floor gap

Put a precise amount of dust in the cracks of the floor slats, repeat the suction three times, and then measure the amount of dust collected.

Carpet

Carpet dust removal: Place a certain amount of metal gravel on the experimental carpet, and measure the total amount of metal gravel removed after three vacuuming.

Carpet to remove grains: Sprinkle 30 grams of grains on an area of ​​70 square centimeters on the experimental carpet. Then at a speed of 1 meter per second, move the dust in a zigzag pattern.

Carpet fiber removal: Put 1 gram of fiber on a 50 square centimeter area on a standard wool carpet, and then press it with a roller. The professional evaluation team evaluates the results and records the number of repetitions required to completely remove the fibers.

Vacuuming the edges and corners

Measure the width of the vacuum by vacuuming the mark left by the main brush. Then, by measuring the suction power outside the width of the brush, the ability of the vacuum cleaner to clean the corners of the wall is inferred.

Performance of handheld vacuum cleaner

If the cordless vacuum cleaner has a detachable handheld vacuum cleaner, it will pass two tests. One is to simulate the removal of a large amount of garbage to see if it will block the vacuum cleaner. The second test is to use very light paper scraps to detect whether the vacuum cleaner will blow away the paper scraps.

Energy consumption

We measure the power consumption during the charging process and the power consumption in the standby state after the charging is completed.

Noise

Not only using instrument measurement, but also combined with subjective evaluation by the expert group.

Endurance and suction loss

Use the main brush to measure at the maximum suction setting until the battery is exhausted.

We measure the initial suction and the suction after 7 minutes of uniformity operation to detect the loss of suction.

Ease of use

The expert team conducted a comprehensive assessment of the following aspects:

• Assembly: Preparation of the vacuum cleaner and installation of accessories.

• Grip and move the dust brush: the comfort of the handle, the height of dust collection and the feeling of moving the dust brush.

• Control and indication: the position of the switch button and whether it is easy to reach. Suction adjustment, various prompt feedback such as suction gear, remaining space in the dust box, etc.

• Carpet vacuuming: When the suction power is maximum, the resistance and maneuverability of the dust brush moving on the carpet.

• Hard floor dust collection: the movement resistance and maneuverability of the dust brush on the floor tiles.

• Stair vacuuming: Use the provided accessories to assess whether the stairs vacuuming is convenient.

• Vacuuming of other surfaces: Test the ease of vacuuming on sofas, high places, home partitions, or bottoms.

• Hand-held detachable vacuum cleaner: evaluate the overall experience of use.

• Storage: Evaluate whether it is convenient to store the vacuum cleaner vertically on the charging station.

• Maintenance: how often the dust box/bag is emptied, and how easy it is to remove and install.

• Motor filter: easy to remove, clean and install the motor filter.

• Battery charging: the convenience of charging, including putting on/off the charging station and reminding the battery during charging.

• Manual: Whether the content is complete and sufficient, whether the font size is easy to read, and whether the illustrations are clear.

According to the importance of the aspect, we assign the weight as follows:

Performance 60%

Ease of use 22%

Run time 8%

Energy consumption 6%

Noise 4%
