Top 5 Best Automatic Toilet Bowl Cleaner Consumer Reports: Editor’s Pick

To help you keep things squeaky clean, we have reviewed some of the top products in this category, along with a short guide to help you choose the right one.

The 8 Best Automatic Toilet Bowl Cleaner Consumer Reports Review:

Keeping the toilet clean is not only necessary for the sake of cleaning but also for hygienic reasons. Here are the top cleaners.

1. Clorox Automatic Toilet Bowl Cleaner

In the case that the area you live in has hard water (it refers to mineral build-up – calcium or magnesium, for example), you know how hard it is to keep your toilet stain-free. It’s crucial to constantly clean things, but that’s not very practical.

The first pick that we have for you will keep cleaning your toilet bowl continuously and prevent stains with ease. And the main reason it can do that is the bleach formula, which effortlessly gets rid of grime and build-ups.

Not only does it keep the bowl stain-free, but it also kills bacteria and terminates mineral deposits. If you cleaned the toilet with traditional cleaners every once in a while, it wouldn’t nearly be as effective as this.

You only need to drop in one of these tablets in your toilet tank, and it will keep cleaning things with every flush. This pack contains six tablets in total. And each can last up to three months, which gives you superb value.

However, as it contains harmful elements, you need to be extremely careful when handling it. Moreover, as it uses bleach as the primary ingredient, your toilet bowl’s longevity might take a slight hit, although it’s mostly negligible.


  • Up to three months of cleaning
  • It cleans hard water stains
  • Continuous cleaning
  • No harm to the septic tank
  • Impressive value for money


  • Contains dangerous ingredients
  • You still might need to scrub it occasionally

At this point, we have the Fluidmaster from Flush N Sparkle. Unlike the usual tablets and automatic cleaners that you are used to seeing, this product ensures a quick and efficient cleaning mechanism that keeps everything clean for a long time.

Before we get into the good things about this cleaner, we should talk about the caveat – namely, the installation process. Many people prefer drop-in tablets for one reason – installation for these products seems tricky from afar.

However, the process isn’t too complicated; moreover, one cartridge can last up to three months, and you can get refill cartridges and replace them effortlessly. Furthermore, it will fit most toilet systems, so that’s not an issue either.

Another impressive bit that it ensures is that you won’t need to go through the taxing scrubbing process, which is terrific. Moreover, you end up with a better result as it cleans the toilet bowl with every single flush.

If you’re worried about whether it will harm the tank or flapper, it won’t. And given that it doesn’t leave any residue in the tank, this is an excellent option if you want the best automatic toilet bowl cleaner.


  • No damage to the tank or flapper
  • You won’t need to scrub
  • It lasts up to three months
  • Frequent cleaning
  • Well-suited for most toilet designs

Before we get to the main discussion – no, it’s not the number of flushes this product can last up to; it’s the manufacturer’s name. That said, this product might as well last you for up to 2000 flushes.

This cleaner is essentially a bleach tablet that you need to drop inside the toilet tank and forget about it (for up to three-four months, at least). As this ingredient is known for, it will kill any bacteria from the toilet bowl.

Not only that, but it also helps get rid of any foul odor, which is crucial. However, some users do not like the smell of bleach, so that’s something to think of. Nevertheless, its constant cleaning is a fantastic feature.

Any time you flush the toilet, the bleach formula in this tablet cleans up your toilet bowl, getting rid of any stains and grime. Not only that, but it also provides protection against mineral deposits caused by hard water.

A persisting issue with many toilet bowl cleaners is the odor they have – and this especially applies to bleach-based products. That smell repels many users (quite understandably), and thus, we have found a cleaner that alleviates that issue.

This cleaner comes with what the manufacturer calls the ocean-fresh scent, which is so much more tolerable than the smell of bleach. But now, let’s move on to the product’s mechanism, which requires clipping to the toilet rim.

That means, unlike the drop-in cleaners or cartridges, you need to clip it onto such a position of the toilet where it has the most water flowing. This method allows for a thorough cleaning right when you flush.

And it does not lack anything in terms of protecting against bacteria. The antimicrobial protection here is quite remarkable, and one bar will work for up to eight weeks. Therefore, this package of six provides you with long-lasting cleanliness.

There is one issue that you should keep in mind, though. Some users have found that the clip fell into the toilet once the bar dissolved. Other than that, this product is excellent at what it does, and we wholeheartedly recommend it.


  • No odor of bleach
  • Quite easy to install
  • One bar lasts up to eight weeks
  • It provides antimicrobial protection
  • Impressive resistance to stains


  • Some users reported the clip falling in
  • The smell is too much for some

  • Package Dimensions: ‎ ‎ 11.89" L x 9.25" W x 1.02" H

Up next, we have yet another product from Clorox. And while things may look similar, there’s a slight distinction between them. But before we talk about that, let’s get into the mechanism and effectiveness of this cleaner.

First of all, this is a tablet-style product, meaning you need to put it in your toilet’s tank when the water level is low. There are no extra hassles that you need to keep in mind, so the installation process is relatively straightforward.

This cleaner also uses bleach as the primary cleaning agent, and we can see why. It can effortlessly kill bacteria and eliminate any odor – that too for a significant period (up to two/three months).

There’s no issue with removal, as you only need to put another tablet in once your current one dissolves. Although, there are a few caveats; the first one is the odor that bleach has, which many users don’t like.

Moreover, it’s not entirely harmless for your toilet system. Nevertheless, this pack with six tablets does a remarkable job of keeping things clean. And the price-performance ratio makes this product an excellent one.


  • Eradicates bacteria efficiently
  • Protection against rust build-up
  • It lasts up to two or three months
  • Quick and regular cleaning ability
  • Straightforward installation process


  • Packaging could be better

Depending on where you live, stains caused by hard water can be a rather persisting issue. Essentially, it refers to a mineral build-up in the toilet bowl (due to the higher level of minerals in the water), which ends up creating stains.

Now, not every cleaning product can effectively work against this issue, so you need to pay attention to it. The product that we have next for you comes from Iron Out, which can effortlessly remove such rust stains.

It uses the commonly-seen tablet method to work, meaning you only need to drop a tablet inside the toilet tank while the water level is low. Hence, it also means that you won’t need to go through a tedious installation.

Another impressive side about this cleaner is that it does not harm your toilet system’s various elements – namely the septic and toilet tank or plumbing. This bit is crucial, as this damage over a long period can be fatal.

Each tablet in this pack can last up to 45 days, and given that it comes with 12 in total, you can achieve a long-lasting result. Finally, its rust-stain removing capabilities make it a fantastic choice.

NeverScrub Automatic Toilet
  • NeverScrub Automatic Toilet Cleaning System

Many people worry about the effects of automatic toilet cleaners on their septic tank and plumbing system, and rightfully so. Moreover, many of those products are far from being environment-friendly, which our next pick is, thankfully.

The automatic toilet cleaning system from NeverScrub comes with a cartridge-based mechanism that you have to fit on the back of the tank. Afterward, you only need to connect its tubes to the fill valve and overflow pipe.

Granted that some people might find the whole process repelling, it’s still worth the hassle. And after the initial set-up, you only need to replace the cartridge, which doesn’t take long (moreover, one cartridge can last you up to three months).

Another bit that makes this product unique is the manufacturer’s patented delivery system, which can clean even the toilet rim’s underside. Moreover, it features a special protection system against stain build-up.

What makes this system remarkable is that the treated water doesn’t even come in contact with the tank’s sensitive parts, which keeps things safe. And while it can be slightly pricier than some options, that feature makes it worth it.


  • Cartridge replacement is straightforward
  • No contact with the tank interior
  • Cleaning with each flush
  • It doesn’t harm the septic tank
  • Eco-friendly ingredients


  • Some find the installation tedious
  • A bit costlier in comparison

There is a reason why tablets are one of the most popular forms of automatic toilet cleaners – they are usually affordable, provide decent results, and last for a reasonably long time. Our next pick is a tablet, too, this time from Air U+.

What we really appreciated about this product is the water-soluble protective film that covers the tablet, which keeps you from harm’s way. Most other cleaners of this form do not come with such protective measures.

As toilets often face smell issues, this product comes with effective methods to get rid of any odors. Nevertheless, some users do not like the smell these tablets have – although that largely depends on personal preference.

This package comes with 12 tablets in total, and each one can last up to 15 to 20 days or around 300 flushes. Therefore, it provides you with a reasonable price to performance ratio along with its remarkable performance.

The installation method is as simple as dropping the tablet in the tank, so there’s no issue there either. Lastly, the ability to automatically clean and protect the toilet bowl from staining makes it a suitable choice as the best automatic toilet bowl cleaner.

Buying Guide: What to Consider When Select Automatic Toilet Bowl Cleaner

Best Automatic Toilet Bowl Cleaner

Compared to the typical options, automatic cleaners are much simpler to use. However, that does not mean that choosing one is as effortless, what with all the chemicals they use. So, here’s something to assist you with that.

The Formulation

The first thing you should look at is the chemicals the cleaner uses, which determines its effectiveness. Furthermore, different products will emphasize various means – it could be disinfection or stain removal and so on.

Many of them contain eco-friendly elements, which aren’t harmful to the environment like the typical cleaners. However, some of those products aren’t as effective, so you need to keep an eye on that factor.

Moreover, the user’s safety is another issue that many toilet cleaners might hamper. For instance, if a user has chlorine sensitivity, it’s wise to opt for a product without chlorine bleach. And that formula is relatively standard for liquid or capsule cleaners.

Of course, more potent elements like bleach have a quicker effect and will seem to clean much quickly, so you’ll have to choose.


You probably have seen many types of products when trying to find the best automatic toilet bowl cleaner. And there’s no absolute answer as to which one is the best, as it depends on the specific product.

  • Gel

As their name suggests, these products use a gel formula that essentially creates a coating on the toilet bowl upon usage. These will firstly ease up any tough stains to allow for a more straightforward cleaning process.

Furthermore, having them will ensure that the bowl doesn’t get dirty as fast as it would’ve without the protective coating.

  • Capsule/Tablet

These products are also known as drop-ins, which should give you a better idea of how they work. You only need to drop the capsules inside the toilet tank. Afterward, the water will have the solution mixed into it every time you flush.

  • Cartridge

You will find that these cleaners work in a somewhat similar manner as the tablets. Firstly, you need to install the cartridge inside the toilet tank, which will release a cleaning agent in the water.

As a result, that agent cleans your toilet bowl with each flush, which is quite an effective way of cleaning.


Toilet cleaners can be somewhat dangerous to both your health and the environment, as you can imagine from the previous section. And this will depend on the ingredients of the products that you purchase.

Eco-friendly products are generally not going to harm you. Furthermore, they are better for the environment, as cleaners with toxic chemicals severely increase air and water pollution.

It would help if you also remember not to allow your pets or children near the toilet’s tank, as the toxic elements can harm them. Furthermore, some of the typical cleaners can be harmful to your septic system, so keep that in mind.

Cost and Value

The duration your automatic cleaner lasts is crucial, as it determines the value you get out of it. For instance, some products that you leave inside the toilet tank will give you a count of how many flushes it will last.

On the other hand, some products last a long time but fail to provide an impressive cleaning result. That’s why you need to look out for both sides, as striking a balance between those two is essential.

Types of Toilet Cleaner

Having enough knowledge about your options is always a good thing, regardless of whether you opt for them. Here are some of the most popular cleaners:

  • Liquid Cleaners

These are perhaps the most common option that you will find in the market. You need to spray it on the toilet bowl and get to cleaning. As you can imagine, you might require a bit of elbow grease, but these cleaners provide a solid performance.

  • Cleaning Tablets

Tablets are a form of automatic cleaners that you have to put inside the toilet tank. Every time you flush, the ingredients (bleach is rather popular) clean everything without you doing anything else. However, you might need to clean things occasionally yourself.

  • Gels

You can get these cleaners in two forms – either as a disc that you can fix inside the rim or as something you need to squeeze on the toilet and clean it afterward. These products do a fantastic job of getting rid of the grime and stains.

  • Cartridges

These also need to be put inside the toilet tank, and they clean things up as you flush. The number of flushes they last for can vary depending on the formula and quality of the product.

  • Powder

Many people like using cleaners that come in this form. The formula can vary depending on the product – bleach and sodium borate are commonly seen, for instance.

Final Words

Your toilet is one of the parts that require the most attention in your household. Not only can they look bad, but leaving them as is can also allow for specific health issues to rise.

The products mentioned above can undoubtedly take the work off your shoulders if you are looking for the best automatic toilet bowl cleaner. Make sure that the cleaner you get suits your preferences and needs, and enjoy a squeaky-clean toilet.
