How do they work?

For the non-plumbers (like us), auto flush toilets for home (also called automatic flushers) can be vague and intimidating creatures. This equipment, however, is not as complicated as we think. Most of us may believe that installing it will alter a huge part of our toilet and plumbing system, but, this is not the case.

Instead of pressing the handle or button of the toilet to lift the flapper, there is a sensor that makes use of infrared light. The infrared then forward electric current, which in turn activates the valve of the toilet. By simply standing in front of the sensor or placing a hand near it, the toilet flushes automatically.

The equipment runs on batteries such as AA and C types depending on the auto flush toilet. There are different kinds and installation process that also depends on what kind of toilet you have at home.

​​​How We Assessed & Evaluated These Auto Flush Toilet for Home

Auto flush toilets for homes are one of that equipment that requires proper understanding before you can have a comprehensive review of each product. It is challenging for us to find suitable material to begin.

We started off with online research, where we first look at forums to know the product better other than our knowledge about it. We looked into forum sites to crowdsource information asking the power source of the auto-flush toilets and how it works. Then, we also visited online sellers and manufacturers to understand its features and benefits.

To support our online data, we further talk with offline sellers and family and friends who are using an auto flush toilet for their homes. We tried seeing how it works, its installations, their concerns, and recommendations.

We then created a list of auto flush toilets and gathered 11 products as our first top auto flush toilets. We narrowed it down to five based on the selection criteria we have developed from our data research.

After having the top five choices, we formed a group of testers to make use of the product from installation to its usage. This part is the most challenging because we need to find the right toilet that fits our top five. We also have to get a plumber to guide us to prevent breaking our sample toilets. 


​Top 5 Auto Flush Toilet for Home Product Reviews

First on our list is the Santeen Sanitary Automatic Hands-free Touchless Flush.
This auto flush toilet for home looks similar to the FlushMinder Automatic Dual-Flush System DIY Complete Kit with its wire connectivity, flush systems and the power of 6 AA batteries.

With the installation, this product is relatively straightforward. According to the testers, it has a comparatively longer wire allowing more choices in setting the sensor depending on the users’ preferences.

The sensor location is again outside the tank with its wired connection with the mechanical part of the flusher inside the tank. It is also similar to that FlushMinder with the dual flush setting. Hence, the sensor is also fronting the user making it convenient to use as it flushes without the need to activate the sensor manually.

The sensor of this auto flush toilet is also decent, where it flushes when needed. It also conforms to its dual setting giving the users pre and the standard flush. However, there are instances the sensor might be too sensitive that the automatic flush activates prematurely.

What our testers love about the Santeen Sanitary Automatic Hands-free Touchless Flush is its capability to set it to single or dual flush. The dual flush allows half and full flush setting, while the other is the standard flushing mechanism. The testers noted that this feature not only gives you more choices but also remedies the issue of water wasting.

This equipment is powered by 6 AA batteries, which its description said that it could fuel more than 20, 000 flushes. We were not able to hit this flush times, but it works even with the several flushes during the testing. 

What We Liked

  • Fairly easy installation
  • Single and dual flush settings
  • No hands needed 
  • Batteries seem powerful

What We Didn't Like

  • Sensor seems to be too sensitive for some users

Our second auto flush toilet for home is the FlushMinder Automatic Dual-Flush System DIY Complete Kit attaches to the flush handle on standard toilets. The ONE and ONLY autoflush kit that converts single-flush toilets into fully automatic dual-flush. Great Cat Potty Training Accessory. Model: ASFS-TA1.

This equipment can be placed outside of the tank of the toilet, which is compatible with most of the standard lever flush toilets. Thus, our testers believe that it can be used with most of the homes. It is still vital that you check your own toilet to check its suitability.

As to the installation, our testers (even the first timers) found it easy to work on it. It took them a few minutes to figure out what goes with where and how to place the parts accurately. However, compared to the other equipment this has relatively easier.

The sensor location of the FlushMinder Automatic Dual-Flush System DIY Complete Kit should be facing the user to activate the dual flush systems. There is no need to wave hands to flush because it uses the user’s presence even while using for it to function. It can be suspended on top of the tank or lever.

There are issues with the wire connecting the sensor and its mechanical system. Some users think that it is too short to have liberty in hanging. Other testers feel that it is enough because it has a dual flush detecting the user’s presence while in use and after.

According to the testing, the sensitivity of the sensor is good and well-working for the first half and second full-flush. But, there are testers who believes that double (1-½) can be a waste of water.

The battery of this equipment is said to provide as many as 10,000 flushes. 

What We Liked

  • Compatible with most home toilets
  • Easy installation
  • No hand-waving

What We Didn't Like

  • exclamation-triangle
    Dual flush can be an issue of water conservation

The third stop is the Zurn ZERK-CPM E-Z Flush Automatic Retrofit Kit for Closet and Urinal Valves with Metal Cover.

Now, this auto flush is quite limited as to its compatibility with the toilets for home use. Its description provides that it can be used with urinal and/or water closet flush valves. The valve of the toilet is outside the tank. Again, check your toilet because most of the home toilets of our testers have different flush settings.

Since it requires external installation, the process was smooth and without complications and need of other tools. Our testers especially the first time users find this to be among the easiest and speediest equipment to install.

As it replaces the handle of the toilet flush its sensor is also located outside and facing the user. Thus, you can simply zip up, and while doing so, the flusher automatically works. There is no need to hover hands to make it work/

This Zurn ZERK-CPM E-Z Flush Automatic Retrofit Kit for Closet and Urinal Valves with Metal Cover has a 3-second delayed feature to ensure that there is no false flushing. Our testers have different views on this feature.

All of the testers think that this is advantageous as it can help in conserving the water by preventing premature flushes. But, there are those who experienced more than a 3-second delay that they have to do a mini dance before it flushes.

There are reported incidents that this equipment has repeated flushing causing flooding. For the entire duration of the testing, there was no continued flushing. Our testers pointed out that it might also be coupled with plumbing issues. 

What We Liked

  • Easy installation
  • No need for a hand-hovering mechanism
  • Prevents premature flushes

What We Didn't Like

  • Limitation with toilet compatibility

The TECHO Touchless Toilet Flush Kit, Battery Operated, 8" Sense Range, Tool-less installation, Automatic Motion Sensor Toilet Flush Kit is a type of auto flush toilet for the home that is meant to be placed in the tank of the toilet, which can be connected with the flapper or canister type of toilets. You need to check what kind of toilet you have at home before choosing since this flusher is limited to flapper and canister.

Its description provides that 10 minutes is all it takes to install the flusher fully. During the testing, the installation took more than 10 minutes considering that these testers are not experts. They have to repeatedly check the manual to ensure that they are doing it correctly. The testers, however, note that it is important to read the instructions carefully than to end up with a faulty flusher.

With our sample toilet, the sensor location is facing the ceiling. That is, you need to wave your hands on top of the sensor for no-touch flushing. Our testers have different views on this feature.

Some of them believe that it is okay because it still promotes no-touching on the handle. The others think that it still requires manual flushing by hand-waving, which can be inconvenient for those who have special considerations like small children and the elderly.

The promised range is up to eight (8) inches. Our testers think that this range fine since you need to hold your hand over it rather than detecting presence while in use. It also comes with more than 30,000 flushes with its 4 AA batteries.

There are reports that the sensor does not work after several weeks. Our testing period cannot determine such because it is only within a week. However, some testers experienced delayed flushing even after several minutes.
ntar Fasciitis, Sore Joint has the biggest volume at 16 ounces.

The ounce can be considered a minor criterion because our focus is on the actual performance of the product. Although, our testers pointed out that a large ounce makes it convenient for those that use it regularly as they don’t have to buy several jars or tubes.

If the Biofreeze Professional Pain Relieving Gel is green, this pain relief gel comes in blue color. You don’t have to be anxious about its color though as like the Biofreeze is also has a very small hint of stain and even none to other testers.

They also like that its odor is not overpowering. You can still tell that there is some minty scent to the gel, but, it is not as strong as the other products in this review. Some of the testers even said that it is milder than the product they are currently using. S

With its pain-relieving effects, its cooling effect is fast. You can feel the coldness and the dulling of the pain seconds after you applied the product.

An issue that they have observed from this pain relief gel is that even with the fast-acting relief, it is not very strong. It might be because it has 2% menthol as an active ingredient.

This pain relief gel also does not last very long. The relief and coolness last only a few minutes then you have to reapply.

What We Liked

  • Relatively easy installation
    8 inches sensor range
  • Works with most flapper and canister toilets

What We Didn't Like

  • Sensitivity seems weak
  • Requires hand waving to flush

Completing our top five auto flush toilet for home is the Rubbermaid Tank Auto Flush, Wireless.

The first impression of our testers with this product is its complicated parts. It was confirmed when they tried to put it all together. It is not very difficult that you will have to call in an expert. Although, its instructions need to be read and reread carefully as it seems a bit vague.

This product is similar to the Santeen Sanitary Automatic Hands-free Touchless Flush and the FlushMinder Automatic Dual-Flush System DIY Complete Kit, which can work with most valve retrofit kit and fixture type tank toilet. It can fit the most common toilets built for homes.

Its sensor may be located outside of the tank where it can be pinned over it to detect the presence of the user. The equipment uses the similar mechanisms as other products in the review with sensors located outside. This auto flush toilet also faces the user to detect their presence for its activation.

The testers love that the Rubbermaid Tank Auto Flush, Wireless can have several settings or adjustments. It can be adjusted to have it on object detection that flushes when an object is detected, or you can add a delay. There is also hand-waving feature, where you wave your hand.

Our testers find the product to be less sensitive than the other products on review. Despite the settings and adjustment, the flusher takes time more than the other products before it can flush.

This equipment is powered with 4 D batteries and is said to flush up to 100,000 flushes, which is quite powerful. We were not able to test it up to 100,000, but every flush as the right pressure. The testers also said that good-working toilet might also add to such performance. 

What We Liked

  • Various sensor setting types
  • Compatible with most home toilets
  • External sensors for easy activation

What We Didn't Like

  • A bit hard to install
  • Sensor seems a little weak
