For many men, shaving is akin to a ritual. Some people prefer to use razors and shaving brushes, while others choose electric shavers. Regarding the latter, it is worth noting that they are represented on the market in a rich assortment. In order not to get lost in this variety, let’s find out what the differences are between the two main types of similar devices (rotary and foil razors).
How it works and how it works
First, let's look at how these units are designed. It was the differences in design that determined the nature of their work.
Rotary razor
The main components of a rotary razor are:
- plastic housing;
- electric motor;
- battery and “charging”;
- rotary knives (titanium is best);
- mesh disk.
The working process of this design begins with a motor that receives current. There is an eccentric gear on the drive shaft coming out of it, and the same parts are installed on the spindle of each blade. These elements are fitted very carefully, which allows for high rotation speeds.
The hairs themselves are cut off upon contact with the junction of the blade and the mesh.
Rotating around the circumference of heads set at different angles, the blades remove hair in hard-to-reach places. Important! Due to the large number of rotating elements, such models require more frequent lubrication.
Due to their more complex design, rotary razors are more expensive than foil razors. The most popular are products with 1-3 heads, although there are also 4-5 ones. As for blades, double blades are considered the most practical.
Foil shaver
Such units consist of:
- housings;
- electric motor;
- battery and charging cord;
- steel mesh cover;
- movable blade or blade knife.
The main unit is a combination of a movable knife and a fixed mesh lid. The last hair that hits the surface is immediately captured and cut off by vibrating blades.
The more grids, the more effective the shaving (usually buy products with 3-4). If you take a closer look, it turns out that these devices may differ from each other except in the position of the grids relative to each other. And their displacement is often minimal. The operating principle itself remains unchanged.
Rotary electric shavers
The rotary type of electric shavers is superior to the foil type with a perfectly clean shave. Long hairs and short stubble are cut off at the root using blades. This ability is not available to all foil razors.
The design of rotary electric shavers differs from foil shaving heads. The movable knife in it is located behind a round static blade, which comes into contact with the skin when shaving. Along the perimeter, the static blade has slots through which the hairs are cut by a rotating knife. It is driven by an electric motor located in the razor body.
What types of rotary electric shavers are there?
In rotary razors, the shaving head may have one or more blocks. One block includes a pair of blades - movable and static. In models with three blocks, round static blades are located at an angle relative to each other and are independently mounted inside the shaving head. This design provides better contact between the razor and the skin and follows the contours of the face. There are models that have four or five blocks of blades at once. This improves the shaving result and makes it more comfortable.
Most rotary electric shavers are equipped with a trimmer. It is located inside the body and, if necessary, the trimmer can be pulled out and the contour trimmed.
Pros and cons of a rotary razor
Many modern models, similar to conventional shaving machines, have a double blade. It gives the best effect, making the skin smoother. One blade lifts the hairs, and the other shaves them off. This mechanism allows you to remove a larger number of hairs in one razor pass, regardless of the direction of their growth. Particularly good results are obtained by models with blocks, in which, in addition to slots along the perimeter, there are holes on the round blade itself. Such units can simultaneously shave both long hairs and short stubble, which passes through the holes in a similar way to mesh electric shavers.
The disadvantage of rotary razors is that they have a rougher effect on the skin compared to the foil type. For men with sensitive skin types, shaving with a rotary razor will cause irritation. Models that can be used for wet shaving help to partially solve this drawback. Rotary-type devices are also distinguished by quite impressive dimensions. Sometimes this may not be convenient when using and storing the razor.
Which type of razor is better: rotary or foil, what is the difference and how to decide on your choice
Having dealt with the technical “stuffing” of both types, many immediately ask themselves: which one is better suited for a particular skin type. It is this moment that is often decisive when purchasing.
For rough stubble
Rotary models cope better with such vegetation: their characteristic holes will shave off any stubble at the root.
They also have other advantages:
- movable cutting blocks can work in different planes, perfectly following the contour of the face;
- knife self-sharpening function, which extends the service life of the cutting edge;
- even affordable products with two knives in a block are not much inferior to more expensive ones, where there are 3 or more of them (moreover, they often surpass them in the final result).
Did you know? Until the beginning of the 19th century, shaving and haircuts were considered medical procedures, and barbers were considered equal to doctors.
But a rotary razor has a significant drawback: after processing, you feel noticeable irritation , so this device is not suitable for everyone (and this is the main significant difference for the user).
For sensitive skin
This kind of work is more suitable for a foil razor. Unlike the rotary unit, which can sometimes simply pull in hairs, causing pain, the mesh strips grind the stubble immediately without causing discomfort.
Other advantages include:
- ease of mesh replacement;
- more repairable design;
- quick adaptation to this shaving regimen;
- possibility of removing thick bristles (the length of the grip is longer than that of the rotor).
True, all these advantages pale slightly against the background of the “family” disadvantage of mesh blocks - the softness of the processing does not always compensate for poor shaving in hard-to-reach places .
Find out what are the advantages of using electric shavers over a conventional razor.
Foil electric shavers
Foil electric shavers work due to the alternating magnetic field created inside, which drives the crank mechanism. This engages the working part of the blade and it, making reciprocating movements, cuts the hair. When shaving, the blade does not touch the skin; it is separated by a protective metal mesh. The hair is cut with a blade passing through a hole in the mesh.
The part where the blades are located in an electric razor is called the head. The working part of the head is covered with a fine-mesh mesh to prevent contact with the shaving knife. This eliminates the possibility of injuring the skin. Using a foil shaver may cause irritation during the first few shaves. But after the third session, the skin usually gets used to it and shaving does not cause discomfort.
What types of electric foil shavers are there?
The shaving head in a foil electric razor has variations. It can contain from one to three blocks that are closed with a separate protective mesh. Optionally, in addition to blocks with blades, the electric razor can be equipped with a trimmer for creating a model beard and mustache trim.
Models of mid- and high-price foil razors can have either an entire floating head or separate shaving units. The floating mechanism allows the razor to better contact the surface of the skin due to the ability to follow the contours of the face.
Pros and cons of foil type razors
Men with sensitive skin types should choose a foil electric razor. Foils cannot boast of a perfectly clean shave, which is considered their main drawback. The strength of such devices is their minimal impact on the skin without causing irritation. Men with very sensitive skin on their faces should pay attention to models whose protective mesh is platinum coated.
Let's compare in more detail
Everything is clear about the fundamental advantages. But the potential buyer is also interested in a lot of other factors that affect the ease of use of the razor, its functionality and, finally, its service life. However, first things first.
Size and comfort
If we talk about sizes, then the primacy will go to mesh units: they are more compact and lighter - this is due to their simpler design.
Important! Before use, be sure to check the condition of the meshes and blocks again - cracks and dents on these planes will cause a lot of inconvenience (and even cuts) when shaving.
Those who like to experiment will love the possibility of working with rotary ones: they can work with a trimmer attachment. Forming a mustache or goatee with such a thing is a couple of trifles. The kit usually comes with an attachment for short stubble.
Similar accessories are used when using foil razors, but they are still inferior in efficiency (which is partly compensated by their large assortment).
Rotary models are also distinguished by a quieter “temper” - most of the products currently offered are practically silent.
In terms of maintenance (meaning replacing the mesh), mesh ones are more profitable - in the case of them, this is a matter of a few seconds.
Ease of maintenance largely depends on the handling of the device. But here, too, the rotor comes out ahead: its elements are stronger, they need to be changed less often, and accordingly, less time is required for maintenance.
Safety
A correctly selected attachment for the “rotor” eliminates damage to the skin.
Although there is a nuance regarding the condition of the blade: a dull edge can chew hairs, which does not give the most pleasant sensation. Did you know? Contrary to popular belief, shaving does not make hair thicker.
The length of the foil razor, coupled with its narrow slats, plays a cruel joke: if you misplace it or press it too tightly to your face, you can get a cut.
Skin after shaving
The rotary heads with double blades stand out: the first lifts the hair, and the second cuts it. As a result, literally in one pass there are no traces of vegetation left on the skin. But men with sensitive skin will have to pay for this with redness and irritation.
Although this picture can also occur when using a mesh system: removing hairs in one step is problematic (often you have to catch the bristles with a bar). Frequently moving the razor over the same area, but in different directions, can result in the same redness.
But, over time, the owners gain some experience, and the number of such maneuvers decreases, which has a good effect on the condition of the dermis.
Spent time
Rotary heads are much faster - rotating at high speed, they reduce the number of passes to a minimum: the bristles are removed in one sitting.
A narrow “mesh,” in turn, tends to let individual hairs through, which slows down the entire process.
Important! When starting to use an electric razor for the first time, let it run idle for a while - a working device will not produce unnecessary sounds such as grinding (and if it is plugged in, it will not heat up too quickly).
Both types can be equipped with a removable mini-battery. This device is capable of working in fast charging mode: 5-15 minutes - and the device is ready for use. It seems like a small thing, but anything happens (for example, you need to shave on the road), and this device really helps out.
Watch a video about the advantages and disadvantages of rotary and foil shavers:
Durability and service life
The movable nozzles of the rotor blocks are little susceptible to mechanical damage (especially if titanium coating is used).
Mesh strips cannot boast of such reliability: although they are made of steel, they are quite thin. Even flying from a low altitude can cause them to dent and require replacement.
It is difficult to provide specific data on the duration of operation. Manufacturers and sellers usually claim that it is practically unlimited. There is a considerable amount of truth in their words: with timely replacement of worn or broken parts, as well as careful handling of electrical components, the device can last for years (if not decades).
Availability of additional functions
Progress does not stand still, which also affected the functionality of the electric razor.
In the characteristics of modern models there are references to:
- self-cleaning, which is considered something of a good practice regardless of the type of device. It’s simple: gel is applied to the knives and placed in a special container;
- the ability to work with a wet shaving method (the type of razor is also not important, although foil devices work worse with gels and foam - the edge tends to get stuck, allowing hairs to pass through). Moreover, moisturizing gel is often supplied automatically, you just need to fill the reservoir;
- floating head type. This is the prerogative of rotary devices. There are also mesh products on sale with similar edges, but their efficiency is lower (a little more effective than “mesh” with arc heads, but in our area this is still rare);
- LCD display. A very useful thing - it shows the battery charge and, if necessary, reminds you to replace the blades or urgent cleaning;
- cooling the skin, reducing the level of irritation;
- recharging via USB connector.
Did you know? The legendary Soviet razor "Kharkov" had a rotary design, and already the first products, released in the late 1950s, had two heads.
The list is impressive, especially considering that many models come with a so-called docking station, which plays the role of a service station for the razor - it disinfects and cleans, lubricates and charges. The main thing is to change the fluid in the reservoir on time.
How to shave with an electric razor correctly and safely
Holding a newly purchased device in your hands, you want to immediately try it out. But any method (be it hair removal with a machine or an electric razor) has its own specifics.
To make the process as comfortable as possible, follow this algorithm:
- First, the skin is prepared for the procedure. If you use the dry method
, you should not steam or moisten it - the blade simply will not take the hairs.
Immediately before shaving, the skin is disinfected (cologne will do) and wait until it dries. Men with a dry skin type can skip this point - such products will cause them a feeling of “tight” skin and flaking. With the wet method,
a non-foaming gel is used. - Turn on the razor. While slightly pulling the skin with your free hand, try to hold the device at a right angle to the desired area.
- Move the working surface with light movements (no need to apply force). The rotor apparatus is moved in a circle, the grid apparatus is directed up and down.
- After completing the procedure, rinse off any remaining hair with warm water; if there is redness, apply aftershave gel.
Important! When choosing a conditioner for wet shaving, pay attention to its composition.
A high-quality gel is produced with the participation of citral (it acts as an antiseptic) and a substitute for medical alcohol - isopropanol. In general, nothing complicated. But for those who have just switched from conventional machines, such an innovation at first may seem like sheer torture - the head seems to be moving in the wrong direction, and there is irritation on the cheeks. Be patient: after a week or two, the skin will get used to it, and the manual dexterity acquired in a short time will turn the shaving ritual into a quick and safe procedure.
Rules of care and use: how to extend the life of a hair removal tool
Like all mechanisms, an electric razor requires proper care.
The key to long service life of the device will be:
- routine cleaning after each use (the hairs remaining there are shaken out from the blades - there is a separate brush for that). The presence of a docking station will only be a plus: the working surface is dipped into a container filled with a special compound;
- Replacement of damaged meshes and blades as needed. Keep in mind that serviceable parts also have their service life. Thus, the shaving heads of rotary razors are prescribed to be changed every 2 years, while for foil razors they must be replaced after one and a half years;
- Regular lubrication of cutting edges. The kit includes machine oil. It is used according to this scheme: a couple of drops are applied to the mesh and spread over its surface. Then the razor is turned on, and after about a minute the liquid will reach the desired point.
Did you know? Before the First World War, British soldiers were officially prohibited from shaving their mustaches .
The electrical part also requires attention: motor, battery and wiring. To keep them working longer, try to keep the razor away from heat sources such as batteries (of course, avoid water ingress).
Also, make sure that the halves of the housing are held firmly: loose fasteners will immediately cause inconvenience during operation, and dust will begin to seep into the unit, which threatens overheating.
The best electric shavers: top 3 according to users
There are a huge variety of such products in stores, so it’s easy to get confused. But in this sea of technology there are models that have become generally recognized leaders. Let's briefly look at the characteristics of the most popular electric shavers.
Panasonic ES-SL41
Foil device with three floating heads for dry and wet shaving. The blades are sharpened at an angle of 30 degrees and move quite quickly (the motor develops 7600 rpm). Washing under running water is allowed.

Powered by battery (charges in 8 hours). The autonomous session time is 21 minutes; if necessary, you can switch to a mode in the range of 100-240 V.
The kit includes a charging stand, a retractable trimmer and a storage case.
But there is no LCD display or automatic cleaning system, although this is the norm for this price segment. Important! When buying an electric razor, ask the seller in detail about the warranty conditions.
The A520 and R520 modifications are identical in technical terms and differ only in color - the first is painted blue-black, and the second sports red inserts.
Philips S3510 and S3120
This is a rotary razor for dry shaving. The same three floating heads, mains/battery power and 8 hours for a full charge. The battery life is up to 35 minutes; the charge status is indicated by an LED indicator.

It comes with a retractable trimmer and is rinsed with water after shaving.
Did you know? In a month, the hairs on the face grow to an average of 0.635 cm.
Judging by the reviews, this is a compact and high-quality product for those who value reliability and simplicity in things.
We found out the differences between rotary and foil shavers and compared their capabilities. We hope this information will be useful to those who want to make the shaving process more comfortable and faster. And let everything go smoothly!
Accessories for additional functionality
Most electric shavers boast a number of additional options. They expand possibilities, create convenience and make shaving comfortable. The most common functions are:
- set of nozzles;
- trimmer;
- battery operation;
- information display reflecting the condition of the razor;
- self-cleaning system;
- automatic supply of moisturizing gel;
- skin cooling system.
Modern models of foil and rotary electric shavers are suitable for dry and wet shaving. The models are protected from moisture getting inside, which allows not only wet shaving, but also convenient care of the equipment. The blades can be cleaned under running water. Each type of electric razor, depending on the model, can be powered by a battery. Not being tied to an outlet and having no wire makes self-care much more convenient.
Battery-powered equipment is convenient to take with you on trips. Rechargeable batteries in razors charge quite quickly. The charging cycle will take literally several hours. There are shavers whose batteries can be charged in a matter of minutes, usually 10-15 minutes.
Most brands produce electric shavers with a set of different attachments. Some models may even have an attachment that can be used to trim the hair on your head. Most often, manufacturers complete the razor with a trimmer, which can be removable or built-in.
The amount of additional functionality is directly reflected in the cost of the electric razor. Maximum functions - higher price.
