Benefits of Installing a Hands Free Automatic Dual Flush Kit:
- Cleanliness: No touch forces regular flushes and helps mitigate the spread of germs
- Versatility: Fits standard “flapper valve” toilets, does not interfere with manual flush handle
- Water Saving: Automatic dual flush computer timer senses for half or full flush as required
- Affordable: Retrofit kit is a much cheaper alternative than purchasing a brand new toilet
For additional information and troubleshooting tips, see the FlushMinder FAQ . . .
This exclusive and innovative dual-flush toilet conversion system fits most standard lever handle toilets with a “flapper valve” and is FULLY AUTOMATIC. Upon toilet use, a computerized human-presence sensor measures the “time-at-the-toilet” and then automatically activates a motorized flusher inside the tank for a half-flush (#1) or full-flush (#2) as required.
One automatic full flush cycle also occurs weekly to keep the bowl refilled when there is no usage . . . great for empty apartments or other vacant bathrooms to keep the sewer gases from escaping an empty bowl. For additional manual Timed Flushes, an inexpensive clock mechanism can be attached to the top of the detection head with double-sided tape. Then an hour hand or multiple hands can be added to pass over the detection eye and trigger 2 or more manual flushes per day (see pic). This simple modification is great for situations where the presence detection doesn’t trigger reliably such as with a cat moving around on the seat or an elderly or disabled person not getting or staying in front of it long enough.
Installation and setup is quick and easy with minimal tools, NO TANK REMOVAL or advanced plumbing skills required.
Runs on standard AA alkaline batteries (included) for up to 1 year or 5,000 worry-free flushes. Saves water and improves sanitation – perfect for children, the elderly or any high-use bathroom area where flushing delinquency is a problem.
Also makes a great cat potty training accessory for autoflush after use . . . see online for cat potty training aids and information, plus note the reviews and YouTube videos from customer experiences. Results can vary widely, so specific cat potty training setup and instructions are NOT INCLUDED and NOT GUARANTEED.
NOTE: Each automatic presence sensor is precisely calibrated and tested in a factory test lab (see pic) before shipment to detect from 0 – 31.5 +/- 4.0 inches (80 +/- 10 cm). Be sure that your toilet and bathroom configuration will allow a suitable installation within this range and with no obstructions.
Additional setup information and troubleshooting tips are available on our Troubleshooting and Support FAQ page and ALL FlushMinder Replacement Parts are available separately upon request.

I help out with my elderly aunt who often forgets to flush, so this is perfect. It took a little figuring out to install, but not a big deal. Funny thing is my aunt hears it flush and then always tells me she remembered, so bitter sweet.

This works great with my cat Felix most of the time, but I did add the clock mod to make sure I get a flush couple times a day. He is usually pretty good about getting in front of the sensor, but he’s so curious that he wanders around the seat a lot, looking down in the tank and all, so think that’s why he doesn’t always trigger the flush. I thought that adding the clock mechanism would look like a kludge, but not really and works perfectly for consistent flushes.

I own a small restaurant in Ohio and have been trying to get it COVID ready and open for months. I don’t have a big budget so could not afford to refurbish the whole bathroom which has regular flush toilets. So the FlushMinder is the perfect cheap solution to make my existing toilets flush hands free. It also turns out to help keep the whole bathroom fresher with automatic flushing. Works great and was quick easy to install. Five Stars ! ! !

We provide maintenance services for empty buildings, including monitoring for temperature, humidity, plumbing leaks, etc. An often over looked problem is having the toilets dry out and letting sewer gasses in which stink up the place. Since the FlushMinder does an auto flush every week, it is the perfect solution to keeping the toilet bowls filled and fresh. Saves us time and money on unnecessary call backs for suspected sewer problems.

If you have a regular flush handle toilet, you can look all you want, but this is the best automatic flush option out there. I am a building engineer trying to help my clients with old style standard bathrooms retrofit for COVID prevention and researched this thoroughly. The problem is cost. You can rip out the toilets and put in commercial grade fixtures at major cost (and construction time) or simply put in this flusher quickly on the existing toilets. I don’t consider it a permanent solution, but it works fine and gets the problem solved. Marley C – NY Plumbing Specialties

Installs easily and works well, only took me about 15 minutes start to finish with no tools. Note the motor mount can break off if you’re not careful with it as I found out. But the box does include an extra and I also see that replacement parts are readily available, so that’s a big plus for a consumer product. Thanks!

This is pretty much a plug and play device with easy install and little setup required. I actually wish it had more programmable features, but i can see that would get complicated for a lot of people. The one thing I really like it is doesn’t interfere with the existing handle flush and it still works the same. So if the FlushMinder doesn’t detect for some reason or I just want to do manual flush, no problem. Taking off 1 star for lack of features but does work well overall. Raymond E

These have been hard to get lately, so I had one on back order, but finally got it and was worth the wait. Once installed and calibrated correctly, it has worked consistently to keep my dad’s toilet flushed without my having to do it. He is disabled and has a hard time with the flush handle which has caused needless embarrassment. Be sure to read the directions all the way through and check your toilet tank setup before starting the install. In my case, I had an old style Mansfield valve in the tank that wasn’t going to work right the FlushMinder motor, so I had to change it out for a standard flapper. Not a big deal but ended up taking longer with a trip to the hardware store. Five Star Product – Andrew J

This device is dope, set it up for two cats,super satisfied when they go and then flush! One note tho, the cable is a bit short, we put it up on the wall but doesn’t sense the front of the toilet. Overall this device suits our needs, if ur cat are toilet train, highly recommend this tool. Saves you time flushing! And satisfaction!!! Lol
Robert Goodall –
For a standard old style flapper valve toilet, this is the best option. I tried the “hand wave” contraption but it was intermittent and just does a full flush, so is not water efficient or cost effective. Plus, the whole unit with batteries is down inside the tank, so they corroded after just a few months. This unit has the detector mounted up outside the tank with the batteries inside a silicone seal, so no moisture gets inside. It was a little tricky to calibrate the first time, but now that I understand how to do it, is spot on each flush. For a “hands free, no touch” flush, this is the best, 5 stars.

I install this for my elderly mom who forgets to flush. She keeps asking me what it’s for and i keeping explaining, but bottom line is that it works. I am not all that handy with plumbing stuff, but installed it myself without tools and did not take long. The calibration was a bit confusing, but there is additional information in the FAQ of the website that answered all my questions. Highly recommend!

We provide cleaning and maintenance services for vacant apartment complexes. One of our constant problems is keeping the toilet bowls full of water. Few people realize that the water in toilet bowl is not only for catching waste, but also for blocking sewer gasses. So when toilets are not flushed for long periods, the water eventually evaporates out of the bowl and then the sewer gasses escape out and not only smell up that one apartment, but the whole building. We used to have to go around and check all the toilets which took a lot time, but now we just install FlushMinders and problem solved. The FlushMinder has this great feature where it flushes once per week whether the toilet is flushed or not . . . perfect for our needs. The cost of a FlushMinder is nothing compared to the cost of having to pay a maintenance man to go around and check all these toilets on a regular basis. I’m giving it 4 stars because the programming is limited, but otherwise works great.

The device is easy to install
By BLon March 17, 2015
I got it for my cat as I am training him to use the toilet. The device is easy to install. It took me around 20 minutes – mainly to adjust/configure the the full and half tank flush. I had to take the lid off the toilet seat and put the sensor on the front side of the tank on the lower part. It waits for the cat to linger and finishes then auto flush about 10 seconds after the cat jumps off. Also the motor doesn’t make much of the sound when it operates so the cat is not disturbed. Love the product!

Toilet trained cat=successful Flusher!
by AC June 17, 2016
Purchased for my TOILET TRAINED cat. After reading previous reviews I was sold. It took a few days for her to adjust as it was something “different”. Praise and treats go along way. Super glad we can leave her knowing there will be a flush every time!

Works for Potty Trained Cats
By CK on July 13, 2015
Got this for toilet training my cat. She’s been an apprehensive potty trainee, but she finally completed her training kit and now she goes straight to the toilet to do her business, which is awesome except she can’t flush the handle, obviously. So I got this device to do that job for her. To work for this specific purpose, the motion sensor has to be mounted on the underside of the toilet seat lid which must now be left open at all times because the sensor is connected by a short wire to the mechanism in the tank that does the actual flushing. That’s fine, because we need the toilet seat lid open anyway so the cat can go when she needs to. If you’re getting this for use with human users, just mount the sensor on the wall behind the toilet instead. Anyway, our apprehensive cat has been unsurprisingly apprehensive about the motion sensor stuck to the open toilet lid. It’s going to take some more training for her to get comfortable with both the presence of the sensor and the sound/commotion of the toilet flushing. Fortunately, the way this device works, it flushes VERY gradually/gently reducing the abruptness of the flush as much as possible. So I’m optimistic. But don’t expect to just install this and have your cat accept it; it’s probably going to need some additional training/encouragement. The device might be a bit tricky to install for someone who’s not a DIY’er, so if that’s not you, get your boyfriend/husband/friend/etc to do it for you. Other than that, great product; can confirm the sensor works on cats.

Works good for my cats, now worried about overuse…
By Warren S on August 23, 2015
I have two cats that are trained (since they were little kittens) to do their business on the actual toilet and not the messy sand box. The trouble was, I had to flush their business for them, and for the time I went on vacation for a few days, the odor from the toilet from not being flushed was pretty bad. This automatic flush system solved my (cat’s) flushing needs. It installed easily, though I thought the double-sided tape didn’t stick well enough to the tank, so I bought a better tape from 3M which did the trick. I have mine stuck in front of the tank and removed the seat cover so that the sensor can work its best for the cats. Next, I sync’d the timing of the flush (the magnets that’s included in the kit) and adjusted the arm that lifts the flapper valve. Easy, works good. Now, I’m worried that the cats might entertain the automatic flushing system too much. I wish there was some programming on it to not allow no more than, say, four or five flushes a day to save water.

FLUSH MINDER IS AWESOME FOR POTTY TRAINED CATS- SEE VIDEOS ATTACHED
February 18, 2015 By MLK
I recently purchased the FlushMinder Automatic Dual-Flush System DIY Complete Kit. My reason for purchase was due to my Cats. My 2 year old cat and 6 month old kitten were about to finish potty training. YES- No more litter box!
As I got close to the end of the training I quickly learned that in order to be successful I would need a consistently clean and flushed toilet. Well with 2 cats and a full time job out of the house- the math was not working out! I researched multiple flushing systems and decided the flush minder would best suit my needs. It offered a delayed flush time to allow the cat to finish it’s business before the flush AND a water saving option for when a full flush was not necessary. I would not only be saving on litter costs but now on my water bill as well!!
I got the kit in the mail very quick and installed it the night it came. Set up took about 30 minutes with some tweaking. Because the kit is designed for human use I did some minor adaptations to make it cat friendly. I moved the kit from above the toilet to the front of the tank- where the cat would be in view, I also used Velcro to mount so I could adjust and remove more easily, and I removed the toilet seat lid as this was no longer needed after training and I didn’t want to chance anyone leaving it down and preventing the cat from using the toilet.
The cats quickly adjusted to this new device on the toilet. They learned that when they are done going it will make a sound and then the toilet will flush. My kitten is sometimes amused by this and runs back to watch the toilet flush.
I just ordered a second flusher for my other bathroom so the cats now have 2 places to go, it’s eco friendly and it saves water and money even when us humans use the toilet!
Here are two video clips of my cats using the toilet with the FlushMinder Automatic Dual-Flush System.
