Review Baseus A3: Powerful Portable Car Vacuum Cleaner

Baseus A3 Review: powerful portable car vacuum cleaner 2022 (15 kPa) / Cars and other vehicles and accessories

I continue to search for a more or less suitable portable vacuum cleaner for cars. My first portable was UNIT YD-508 with cigarette lighter operation, it was inconvenient in that you needed either a working car to power it, or an outlet with a 220V-12V converter. Plus it was in 100W power (by the standards of portable vacuum cleaners, this is considered a lot). But what’s the point in a portable vacuum cleaner if it is powered from 220V? Then there was a 70mai vacuum cleaner – already a rechargeable one. An obvious disadvantage is low power and short operating time (low power is compensated by a long cleaning time for each area, but because of this, the battery is not enough to clean the entire car).

In the photo above, by the way, a comparison of the size with 70mai. 70mai is larger, but lighter due to the plastic body. Baseus A3 has an aluminum body. The vacuum cleaner comes in a white box typical of their products with a logo on a yellow background.

Accessories include a soft case, a 2-in-1 brush and blowing nozzle, a Type-C cable and a bunch of papers. The ability to operate the vacuum cleaner for both suction and blowing pays off: it is very convenient to blow dust out of all inaccessible places and then collect the garbage in the main mode.

Close-up nozzles. I told about the small nozzle above. The main nozzle has 2 modes: a nozzle for collecting debris and a brush for collecting dust / hair, etc. with upholstery and plastic. You need to be careful with the plastic of the car, since the brush has a small nap and you can easily scratch the plastic panels. In general, it is convenient to work, there is no need to constantly change the attachments. Implementation of a nozzle for 4 out of 5. I would like more bristles.

The vacuum cleaner itself is close-up. There is only 1 button and 3 charge indicators on the case, which go out as the charge decreases. The button with a single press turns on the vacuum cleaner for 1 mode (5kPa), with the second press it switches to the turbo mode 15kPa. Honestly, knowing that you can quickly collect garbage at maximum mode, it is used almost always. By the way, the operating time on 1 mode is 50 minutes, and at a maximum of 17 minutes. Mode 1 is good for blowing dust and debris off panels, collecting dust from seats. Mode 2 is ideal for collecting sand and stones under rugs (1 mode is not enough for stones).

A long press on the power button activates the backlight. Shines with diffused light, can be convenient when cleaning in the dark. I personally like to clean the car in the air, in the sun, so I hardly use the backlight.

At the end of the vacuum cleaner there is a hole from which air comes out. A fine nozzle is also placed here, with which you can blow off dust from the panels. By the way, when the vacuum cleaner is working, air also comes out well from the Type-C hole. The Type-C port is shown in the title photo from the review.

The front of the vacuum cleaner. Looks impressive, glossy reflective plastic “head”. The main nozzle is inserted here. There is also a rubber “door” so that the garbage does not fall out back.

Disassembled vacuum cleaner. The dirt collector itself is on the right (with the Baseus logo on it). Its capacity is 70ml. It is impossible to fill it in for 1 peeling (unless you pick them scattered peas or something like that). It is worthwhile to carefully handle the attachment of the dirt collector, not to drop it, so as not to break them off. Below is a HEPA filter and a mesh on it.

Close up of HEPA filter and mesh. By the way, these are consumables, sold separately for $ 10 for 2 pieces. The HEPA filter stops dust larger than 0.3 microns (manufacturer claims). The mesh does not allow coarse dust and hair to pass through the HEPA filter. The filter clogs up very quickly. Actually for this reason, you will very often clean it and at the same time throw out the garbage from the dirt collector. According to experience, for one cleaning of a car, you need to shake it out 5 times (I mean a car that has not been vacuumed for a year. There is a lot of tiny dust, it’s impossible to imagine how much of it).

For lovers of wine and spectacles, I tried to disassemble it, but it didn’t go any further than removing the back cover, everything was glued – there was no point in breaking. It can be seen that there are 4 batteries 18650. From the manufacturer’s statements here 4 * 2000 mAh. There are thoughts to change in the future to Panasonic 3200mAh. It is not clear why normal batteries are not installed right away. There is paralon so that debris does not get inside.

The capacity is claimed to be 28.8Wh. After a complete discharge, 33.7Wh was poured into the vacuum cleaner. Charging is declared 5V, I put it from the QC3.0 unit and the vacuum cleaner was well charged from 12V. Charging time is exactly 2 hours.

Demonstration of work

Vacuum cleaned 2 cars. The first of 2004, which has seen a lot of dust and dirt. The second year of 2015 – everything was much simpler here. Photo before cleaning. In the photo, it seems that not everything is so bad, but when you open the dust collector, you understand how much everything is running. The trick is in the pile: the dirt seems to be not visible, but in fact there is a ton of it. Clean only in turbo mode here, no options.

After cleaning. All rocks, debris and dust have been collected. There is stubborn dirt that needs to be wiped off with a wet cloth, water and soap. Vacuuming in turbo mode very quickly by the way. As the filter becomes clogged with dust, it starts to warm up. By the way, there is an overheating sensor, the vacuum cleaner turns itself off. Overheating occurs most often for one simple reason – the HEPA filter is clogged with the smallest dust and it is already difficult for a vacuum cleaner to blow out air.

The trunk after cleaning. A ton of dirt was collected. There is dust left on the plastic, which can only be washed off with a wet cloth.

A whole bunch of dirt is collected from almost every cleaning site. The filter needs to be cleaned 5 times to clean the entire car. It clogs up very quickly. Clumps of dust, hair, pollen, fluff, and so on, which is large enough, collect on the mesh. The dirt collector contains sand, stones and other large debris. The dirt collector is enough for a complete cleaning of the car, but the filter clogs up very quickly, so everything rests on it.

But the biggest problem is the HEPA filter itself. Its task is not to let the smallest dust into the vacuum cleaner motor. That’s how much dust was in the filter paper itself. It is shaken out only by tapping the filter housing on something hard. Also, by the way, you can try to blow with the vacuum cleaner itself in the blowing mode (although it is better not to do this without a filter). This tiny dust clogs the HEPA filter and the vacuum cleaner begins to mercilessly warm up and shut down. For a long time I could not immediately understand what was the matter: I just turn it on, and it already turns off. Dust all over the wine – clean as often as possible. By the way, there is another possible reason – not fully inserted nozzle, when it has not yet passed through the rubber “flap”. Pay attention to this if the vacuum cleaner starts to warm up.

Cleaning another car

Most of all dirt, as always, is in the driver’s seat. The same situation. There is a lot of stubborn dust that is too tough for any vacuum cleaner – you need to clean it up with a rag and soapy water.

But in any case, the vacuum cleaner removed all large debris and a ton of dust without any problems. By the way, the car was not cleaned for a year either, but is used almost all year round. In general, you could fork out for a professional car wash once a year, but cleaning your car yourself is always more pleasant, albeit for a long time.

The second nozzle handles hard to reach places very well. The main thing is to use it right away, before the main cleaning, as it raises a lot of dust and blows dirt out of hard-to-reach places. Then you need to collect everything with the main nozzle, but this is much easier than separately cleaning each pocket with all the junk.


The Baseus A3 has shown a good increase in power and operating time, now you can slowly clean your car, knowing that there will be enough charge for the entire cleaning. The power of 15kPa is enough even for collecting large stones. In 70mai, it took a lot of time for large garbage, which seemed to be faster to collect by hand. Of the minuses, a small filter and, as a consequence, its rapid clogging with dust, which causes overheating and shutdown of the vacuum cleaner. When cleaning the second car, I already got used to it and shook out dust and debris after cleaning each place in the car (by the way, there was a sea of ​​dirt every time). In this mode, the vacuum cleaner never overheated or turned off. In general, it is a good thing and is far from being “pampered”. Of course, you can use it as the main vacuum cleaner, but ideally, at least once a year, cleaning the interior with a normal vacuum cleaner will be much faster and better. Even so, the portable vacuum cleaner is very convenient.
