Today, we are dealing with products that are more and more developed and if we think about that, we tend to imagine telephones or computers, even everyday objects benefit from it.

This is for example the case of toothbrushes. Indeed, we are now a long way from the simple manual toothbrush that you have used all your life. You can now go upmarket and it is precisely one of these toothbrushes that we are going to test for you today.

This toothbrush is the Flow Sonic from Oclean and in the rest of this article, we will dissect it from all angles and show you that once tested, it is completely adopted!


Let's start at the beginning, namely, a general presentation of this Oclean Flow Sonic electric toothbrush which comes in the form of a package where everything is included to get you started.

Indeed, the basic package contains not only the toothbrush itself, but also a first head to use it immediately as well as a charger to allow you to charge the battery which you will see later is the one of the big strengths of this toothbrush.

In addition to all that, you will also have a user manual that will tell you the main features of this electric toothbrush.

As for the price at which this pack is sold, it is more than attractive. In effect, you will only have to pay 30€ to be able to get your hands on this one, which is very correct given the quality offered. This is even more true when you know that an electric brush is on average more effective than manual toothbrushing.


Now that we have seen that it is possible to obtain a ready-to-use pack for a sum that is very low compared to what can be done at the level of the competition, let's see how this brush works. electric tooth.

Because yes, having an electric toothbrush is more than having a brush capable of moving on its own andreach areas that are not necessarily easy to reach with a manual brush, it also means having suitable programs at hand.

This is for example the case with this Oclean Flow Sonic which offers the following modes:

  • morning-relief : A soft mode to allow you to do your first morning brushing gently and without aggressiveness
  • night clearout : A much more lively mode which aims to get rid of any food that would have remained stuck during the day on your teeth
  • infinite fashion : For this mode, no timer or modified power, you manage the brushing as you wish
  • Breath refresh : Because we must not forget the cleaning of the tongue after that of the teeth, this mode is very useful
  • caring mode : You have sensitive gums which tend to bleed often when brushing, try this gentle mode

To be completely complete on this point, we will finish by indicating that except for the Infinite mode, the duration of each mode is calculated for a optimal brushing of 2 minutes and brush vibrates every 30 s to indicate that the brushing zone must be changed.

This toothbrush, one of the advantages is that you will be able to rinse it without too much trouble. Indeed, it is guaranteed IPX7 on its entirety, which means that you have no fear of it taking on water, for example.

Impeccable brushing!

As we know, an electric toothbrush like this Oclean Flow Sonic has a brushing that will be more optimal than a classic toothbrush. The reason is the movement of the head which is optimized for brushing precisely.

But besides that, this Flow Sonic toothbrush, it offers several other big strengths in terms of brushing. We can for example speak of its brushing speed which can reach up to 76 movements per minute!

We also spoke to you before about the alert every 30 seconds. Thus, you will be able to "cut" your jaw into 4 areas to brush and you will have indications in terms of timing to be sure to effectively brush each of these areas.

Finally, one of the disadvantages of an electric toothbrush is sometimes the noise it makes. Well, you clearly don't have that problem with the Flow Sonic which is only 55dB in use. So you can brush your teeth with peace of mind.


An electric toothbrush like the Flow Sonic is an excellent choice for all the reasons we have just given you. However, there is often a problem, that of autonomy. Indeed, this is what pushes a lot of people to end up abandoning these toothbrushes.

We do not forget to recharge it and finally, it has no more battery and ends up lying around in a corner. Well, you won't have this problem at all with this Flow Sonic, which stands out precisely for its excellent autonomy.

As proof, it is guaranteed 180 days of use due to brushings that do not exceed two minutes before the battery is good to recharge. It is clearly a big asset and you may even forget that it is recharging by force!

The recharge time is a bit long, given that it is 5 hours, but given the battery life, we suspect that it takes a little time to recharge. At the rate of two recharges per year on average, we stay on 10 hours of annual recharge, which is not so huge either.

Strengths and weaknesses

Well then, if we had to summarize the strengths and weaknesses of this Oclean Flow Sonic, we'll start by telling you that it's an electric toothbrush that will quickly become essential for you.

Indeed, no matter what you are looking for or even your type of dentition, you will necessarily find a mode of use that will suit you. No more bleeding gums, for example with almost all other toothbrushes for the most sensitive.

Moreover, with an electric toothbrush, you will have the assurance of leave no area unbrushed. Indeed, it is able to reach places where you do not go with your classic toothbrush and therefore to operate a much more effective brushing.

Only downside, as we mentioned to you, a somewhat long charging time. But given that this toothbrush recharges very little, it's not a disaster either.
