Robi Comb, V-Comb, and Nix Comb Comparison: Electric Lice Comb Review

Electric Lice Comb vs. Metal Lice Comb--Which is Better?


If you plan to purchase an electric lice comb, this article contains a full review of the most popular electric lice combs:  V-Comb, RobiComb, and the Nix Electronic Comb. Each comb is explained in detail below.

Before you go out and purchase an electric lice comb, assuming it is superior to professional metal lice combs, read on…

Most people assume that the more “high-tech” (or expensive) a lice comb is, the better it is at getting rid of lice. The simple truth is that the metal lice combs in my article 5 Best Lice Combs that Get Rid of Lice Eggs outperform all of these electric lice combs. Here’s why…

When people can’t get rid of lice, it is because they are battling two problems:

  1. They are using an ineffective lice product that does not truly kill adult lice. (To find an effective and non-toxic product, you can read my article here.
  2. They fail to remove all of the lice eggs from the hair. Regardless of what lice treatments say on the box about “killing lice eggs,” nits left in the hair will inevitably hatch, and within a few weeks, you or your child will have a full blown lice infestation all over again. 

If you fail to remove every single lice egg from the hair, you will find yourself trapped in the endless lice cycle.

Why Is It So Hard to Get Rid of Lice?

Now that you know what you're looking for I want to talk briefly about your biggest worry (that your child actually has lice) and the question I get asked by parents around the world that have been battling lice….

problem #1

Lice bugs are immune!

Parents around the world are all asking me the same question…. "Why is it so much harder to get rid of lice now?"

Lice have become immune to everything that used to work in the past. Perhaps you remember your mom using a typical lice treatment or mayonnaise and that doing the trick. The new strain of head lice is no longer killed by those treatments, that’s why lice today are termed by people, “super lice,” because they are immune to those treatments. 

I’ve cured thousands of people of lice in my lice center and let me tell you, I don't do it with over-the-counter lice treatments. 

problem #2

Lice eggs hatch!

Most people struggle with lice because they focus all of their attention on killing lice bugs and not enough attention on GETTING RID OF LICE!

If you want to get rid of lice you have to address all 3 of the problems of lice:

  1. Lice Bugs
  2. Lice Eggs
  3. Getting Lice Back

The best way to get rid of lice is to tackle all 3 of these problems at the same time, which is what I teach in my step-by-step video system.

So, if you discover your child HAS lice, don't panic. Just head over to the video system. Follow along with the videos and you'll be done with lice by the end of the day.

Full Article and Review of Electric Lice Combs

The only way to get yourself out of this cycle is to use an effective lice treatment that actually kills adult lice and to remove every single lice egg from the hair.

The fastest, easiest, and most effective way to get rid of lice eggs is with a professional level head lice comb, such as the combs in my article, 5 Best Head Lice Combs. The very best of these combs is the Nit Free Terminator Comb. It outperforms every other lice comb out there, including electric combs. 

So, you may be asking, when is it better to use an electric comb or a metal comb?

An electric comb, such as the V-Comb, can be considered for someone not wanting to use any lice products. 

Many are looking for a natural approach to lice. Instead of using a lice product to kill lice, one could use the V-Comb to simply vacuum them up first, then continuing the process of removing all of the eggs with a metal comb. 

An electric comb can be used for checking large quantities of people for lice quickly.

An electric comb would be ideal for lice checks for camp, daycare, or school. Using an electric comb like the V-Comb, you can check multiple children quickly and accurately for lice.  Instead of spending long periods of time searching for lice eggs, you can run the V-Comb through each kid’s hair a few times, and your lice check is complete.

If your goal is to truly get rid of lice eggs once and for all, then metal lice combs are significantly better.

Even though electric combs seem fancy and high-tech, their focus is on vacuuming or electrocuting lice bugs, not removing lice eggs. The Robi Comb also claims to zap lice eggs, but in my experience, it does not prevent them from hatching. Zapping and vacuuming lice with an electric comb will give you some satisfaction, but you will be disappointed in the long term results if you neglect removing these nits and get stuck in the endless lice cycle.

To get rid of lice for good, you must remove each egg from the hair. Electric combs are not usually adequate for removing every lice egg, so you’ll need a metal lice comb like the Nit Free Terminator Comb to do that. (You can purchase the Nit Free Terminator Comb here.)

If you want to buy an electric lice comb because zapping and vacuuming lice sounds like a good alternative to lice products, by all means feel free. However, you should also purchase a metal comb to remove the remaining lice eggs the electric comb will leave behind. 

Metal lice combs work well in wet, conditioned hair, whereas electric combs require dry hair. 

Requiring dry hair for lice combing doesn't seem like a big deal, but it can definitely be exhausting if your child is screaming because you are raking a fine-toothed lice comb through her dry (and usually tangled) hair. Lice combing dry hair can be painful, especially for children with thick or curly hair or sensitive heads. My experience after working with different hair types is that it is easier (and less painful) to use a lice comb in wet, conditioned hair. Unfortunately, all electric lice combs require dry hair.

Beware… you are more likely to spread lice to yourself if using an electric lice comb on someone else. 

Electric lice combs are meant to be an alternative to lice treatment products, but that means that you are combing LIVE LICE out of your child’s hair. The V-Comb vacuums them into a container, which is nice, but the electric combs “stun” them with an electrical shock. In my experience, the electrical zap does not always kill lice. Many lice I removed were still active and moving.

After you remove live lice from your child’s head, those lice will immediately begin searching for a new warm environment, and the person closest to them at that time is going to be their first choice--YOU! Once you’ve removed those live lice from another person, make sure they go down the drain or in the toilet so you don’t accidentally end up with lice yourself!

If you are interested in purchasing an electric lice comb, here are the best ones on the market:

Electric Lice Combs

#1- V-Comb (Lice Vacuum Comb)

The V-Comb (also known as the vacuum comb) is my top pick for electric lice combs. When combed through small sections of dry hair, it suctions up lice (still alive) and lice eggs into a small mesh bag. An LED light shines into the bag enabling you to see if any lice have been vacuumed up.


After you have finished combing, remove the bag filled with lice and lice eggs from the device, place the provided cap on it, and throw it in the garbage. The mesh bag keeps all the lice securely contained.

This comb can be used without any lice treatment product because it works on live, moving lice. The comb also comes with a cleaning tool so you can easily clean out any lice or nits that may be stuck in the comb after use. 

I have used this comb multiple times, and the concept is a good one. There is something very satisfying about vacuuming up lice and even watching them squirm around a bit in the bag. My clients love to see what I’ve vacuumed up and it is rewarding to see how much progress you’ve made in becoming lice-free.

There are a few disadvantages to this comb, though...

While it is good at vacuuming up large, adult lice, it can miss very small baby lice (also called “nymphs”) and nits. 

The comb also only works on dry hair. Combing through dry hair can be a painful experience, especially for kids with thick or curly hair. 

I found it to be most effective when I used it in long hair because I could easily  section the hair. It was more difficult to use in shorter hair because I could not section it as cleanly. 

The V-Comb cannot be a one-time treatment. The instructions for the comb say to use daily for one to three days and then again on the seventh day to catch “newly hatched nymphs or new head lice.” You must be diligent in using this comb, otherwise you’ll end up stuck again in the endless lice cycle.  

Electric combs like one can also seem pretty pricey at first, especially if you’re on a budget. However, compared to spending perhaps hundreds of dollars on next-to-useless lice treatment products, it is certainly a much better value for your money. 

Be aware that the comb only comes with four non-reusable lice bag containers. If you plan to use the comb on multiple people, or daily for a few days as instructed, you will likely run out of bags. Fortunately, a package of eight replacement mesh bags is available on Amazon if you need them.

The V-Comb is a great way to check multiple people for lice quickly. Performing lice checks at school or camps with this comb is a breeze. Line the children up and simply run the V-Comb through a few sections of each kid’s hair. It is clear and easy to see if a child you’re checking has lice because you will see them in the translucent mesh bag. 

The V-Comb is also a natural way to remove lice instead of using lice treatment or shampoo. If this approach is appealing to you, this may be a good comb for you. I highly recommend that you purchase a metal comb in addition for undoubtedly removing nits and nymphs that the V-Comb may leave behind. (Remember you can find my comparison on electric lice combs and metal lice combs above)

#2 - LiceGuard Robi Comb Electric Head Lice Comb (Lice Zapping Comb)

The high-tech Lice Guard Lice-Zapping Comb uses a small electric pulse to zap lice with a low energy charge. The vibration is supposed to kill or disable lice on contact and electrocute mature lice eggs.

Using a battery as its energy source, the comb emits a low humming noise when it is ready to use. You then comb through small sections of hair. When the comb comes in contact with lice or nits, it stops humming, the comb’s indication that it has zapped something.

After this happens, you clean out the comb with the tool provided. The comb will begin humming again, ready to use.

In my experience, I have not seen this comb literally kill a lice bug with this kind of shock. I’m not convinced that the zapping process does any harm to the lice, besides stunning them. While I know that this “zapping comb” sounds promising, it has some major disadvantages.

The lice zapping comb has a high “false positive” rate. This means that it will react to anything and everything in your hair, including dandruff, dirt, or lint. With this high false-positive rate, it is not even very good for lice checks because it may indicate that someone has lice when they really don’t. While that may not seem like a big deal, when it comes to your kid being allowed to go to camp or come to a school activity or not, you’d much rather know for sure who has lice and who doesn’t.

Additionally, having to clean out the comb every time it comes in contact with lice or nits (or the other stuff) is very time consuming. I had an experience where my comb zapped something (that didn’t end up being lice), and I couldn’t get it to start working again for a long time. I had to clean it, change the battery (even though it was brand new), and turn it on and off several times before it started working again.

It is also not effective at removing nits or nymphs. This comb is not a quick fix for lice. Using this comb is a weeks-long process. In the Robi Comb’s Directions for Use pamphlet, it says, “Comb infested hair daily for two weeks in order to detect and kill any new lice which have hatched since you began treatment.” So although the Robi Comb may zap everything, it does not prevent lice eggs from hatching. Anytime you leave lice eggs in the hair, the endless lice cycle continues.

#3 - Nix Electronic Lice Comb

This comb emits a low electrical charge intended to kill lice on contact. When turned on and ready to use, the comb’s green light illuminates. When the comb comes in contact with lice, the red light turns on, letting you know that you have zapped something.

After you have shocked lice, remove the comb from the head and clean it with the brush provided. Once cleaned, the green light will turn on, indicating it is again ready for use. 

The comb also has a bright LED spotlight available to help you better find lice in the hair. 

The comb’s website says it is “intended to remove and/or kill lice and nits.” My experience is that the electric charge does not actually kill lice or nits. It may stun them for a few seconds, giving you enough time to remove them from the comb, but they do not die.

This comb also has a high false-positive rate because it emits an electrical charge on things in the hair other than lice, such as grass, dirt, or lint.

It is also not effective at removing lice eggs or nymphs. Using this comb is a long process because the comb does not remove eggs from the hair. Nix recommends, “For maximum effectiveness, repeat the treatment every 2-3 days for 10 total days.” Again, anytime you leave lice eggs in the hair, the endless lice cycle continues.

V-Comb vs. Robi Comb vs. Nix Electronic Comb

V-comb v Robi v Nix


When comparing the Robi Comb, V-Comb, and Nix Electronic Comb side-by-side, there is no doubt that the V-Comb is the best electric lice comb out there. It vacuums lice into a disposable container that is easy to throw away, whereas the other electric lice combs only stun lice, and then you must manually remove and dispose of them. 

Electric lice combs overall are not as good as professional metal combs, like the ones in our article 5 Best Lice Combs. These combs outperform all electric lice combs when it comes to removing lice eggs. If only a few nits stay in the hair, the endless lice cycle will continue and you’ll find yourself back at the beginning of this process.
