ScoopFree Ultra Self-Cleaning Litter Box – All You Need to Know

ScoopFree Ultra self-cleaning litter box is one of the most popular automated cat litter boxes these days. It has gained the reputation of being one of the bestselling products on Amazon.

ScoopFree automatic litter box has disposable litter trays which use blue crystal litter. This litter is great for absorbing urine as well as controlling odor.

The disposable tray is what makes this litter box automatic and free from the hassle of cleaning.

The disposable litter tray is used as the bottom unit of the litter box.

So, when cats do their business and eventually the tray gets dirty enough, all you need to do is throw the tray away and use a new one. It’s that simple!

ScoopFree recommends that you should change the litter tray every 20 to 30 days if you have one cat.

For 2 cats, the time span is 10 to 20 days and for 3 cats, the time span is 7 to 10 days.

However, if you have more than 2 cats, it is better to get a second unit of ScoopFree ultra self-cleaning litter box.

ScoopFree ultra litter box has an automatic rack system that cleans the litter by pushing away the waste into a covered compartment.

The rack can be programmed to perform this operation after 5, 10 or 20 minutes from your cat doing her job. If in the meantime your cat enters the litter box again, the timer will reset and start from 0.

The waste compartment is located at the front of the litter tray.

ScoopFree Original vs ScoopFree Ultra

ScoopFree original self-cleaning litter box uses the crystal litter which absorbs liquid waste very quickly and makes solid waste dry out.

After 20 minutes of the cat doing her business, the automatic rake system of the litter box pushes away the dry solid waste into the waste compartment located at the front of the disposable tray.

The timer will restart if your cat re-enters the litter box. The crystal litter absorbs pee in a jaw-dropping speed in the waterproof tray. You’ll have to replace the disposable litter tray after every 1 months.

How ScoopFree Ultra Self-Cleaning Litter Box Works?

  • Suppose your cat enters the litter box and pees on it. Now, the high absorbent blue crystal litter will absorb the liquid very fast.
  • Depending on the program, after 5, 10 or 20 minutes of your cat doing her job, the automatic raking system will run through the crystal and re-distribute it flatly on the litter tray. As the crystal litter absorbs the liquid waste, no clumps are formed and stored in the waste compartment of the litter box.
  • When your cat poops on the litter box, the automatically programmable rake will collect the clump and push it to the waste compartment of the litter box. The waste compartment will open its door, collect the clump and close the door as soon as the rake returns to the first position.
  • The waste trap cover and the waste trap itself are attached with a magnet. They work as a whole unit in the litter box. Thus, they open and close at the same time to receive and contain waste clumps. The trap cover helps to control the odor so, your room remains fresh and healthy.
  • ScoopFree has premium quality rakes on their litter boxes. These rakes don’t get jammed or stuck like other companies self-cleaning litter boxes. These automated rakes change the direction as it continues to swap back and forth within the litter box. The rake moves in a highly calculated scientific manner to re-distribute as much litter as possible on the litter tray and push as much clump as possible to the waste compartment.
  • The crystal litter works best when the atmosphere is dry and there is less to no humidity in the air. With high amount of humidity, the crystals tend to lose their effectivity.
  • Inserting a new litter tray and replacing the old one is very easy and straightforward. All you need to do is place the litter box against a wall, slide the plastic to get rid of the old litter tray, then slide in the new litter tray to the litter box and close the plastic over. Now, pour fresh crystals over it. After that, take the old litter tray, put it in an enclosed bag and throw away to the dustbin.

How to increase the lifespan of the litter trays?

  • The first thing you need to do is place the litter box in a place where there is less to none humidity in the air. Humidity is the number one enemy of crystal litter. As the crystal litter controls the odor by absorbing humid waste, extra humidity on the air will interfere with its operation and thus, reduce the litter’s lifespan. So, don’t place the litter box in places like the bathroom, near the shower place or in the basement. What I would like to do is, place the litter box in a place that has high air circulation. it ensures that humidity is pushed away from the room.
  • Some cats have the habit of urinating on the same spot over and over again. It creates more saturated crystal in one place which is not preferable. So, if your cat has this kind of habit, it is better to occasionally stir the crystal litter to make it less saturated in one place.
  • If your cat has a high amount of crude fiber and ash on her diet, she’ll produce more solid waste. So, the waste compartment may get filled quicker than you think. That’s why it is better to keep your cat’s diet free from fillers or by-products as much as possible.

How to acclimate your cat to the ScoopFree Litter Box?

In general, cats won’t need any additional steps for acclimating them to the automated self-cleaning litter box. However, some cats may need a little help from you to start up the acclimating process. Here are some tips that’ll increase the acclimating speed of your cat to the ScoopFree Ultra self-cleaning litter box:

  • It is a good idea to place your ScoopFree self-cleaning litter box beside the old litter box your cat was already using for the first week. Thus, your cat can go to either one of the litter boxes. It will also help her to use the new litter box.
  • If your cat is not using the new litter box, take some unused old litter from the previous litter box and pour it on the new litter box. You can also add some crystal litter from the new litter box to the old one. It will help your cat to get adjusted with crystal litter.
  • Don’t clean the old litter box. Cats tend to like clean litter box. As the old one will get dirtier with time, your cat will find the new litter box more appealing.
  • Once you see your cat is using the new ScoopFree litter box without any problem, take away the old litter box immediately.

If you have a kitten less than half a year old, then it is better to leave the ScoopFree litter box unplugged and scoop over the litter manually until they cross the six-month age threshold. This way prevents any risk of danger.

What I Loved About this litter box

  • The ScoopFree ultra self-cleaning litter box is very easy and straightforward to use. You don’t have to think about changing the litter box at all. All you need to do is replace the cat litter tray once every month. It takes off the weight of cleaning litter box every day from my shoulder. It also lets me to spend more quality time with my cat.
  • The rake is programmable and equipped with a sensor. It detects when your cat leaves the litter box after doing her job. 5, 10 or 20 minutes after the cat leaving the litter box (Depending on what settings you used), the rake starts to move and re-distribute the litter as flat as possible.
  • Crystal litter is 5 times more effective at absorbing liquid waste and controlling the odor of the feces. It also dehydrates the solid waste and turns these into dry clumps which helps the rake to push it over to the waste compartment.
  • The waste compartment has a plastic lid over it, so it contaminates the solid waste and controls the odor. It works in synchronization with the automatic rake system. Every process is automated. You don’t need to lift a finger.
  • The cleanup process is very hygienic and takes little to no time. All you have to do is, take out the old litter tray once a month, put a cover on it and throw it out at the dustbin. It may only take you 5-10 minutes. Don’t forget to put a new litter tray in the box.

What I didn’t like

  • You have to continue on buying additional litter trays for this litter box. It may get quite expensive if you have more than one cats.
  • If your cat loves to dig, it might block the sensor with piles of clump. Also, excessive digging may leave a scratch mark on the bottom of the litter box.
  • Occasional stirring of the litter may be required if your cat does her job on only one side of the litter box.
  • The area of the litter box is not great for large size cats.
  • With some cats, you may find it harder to shift them to crystal litter.
  • If the weather is constantly humid where you live, this litter box might not be a great product for you.

Alternatives to using litter tray

One of the big limitations of using the ScoopFree Ultra self-cleaning litter box is, you need to continue on buying disposable litter tray for the rest of your life. For a single cat, it might not be that big of a deal.

But if you have more than one cats, the process may get quite out of your price range.

So, here I am giving two alternatives to using disposable litter trays in ScoopFree self-cleaning litter box. However, keep in mind that these alternatives will not work as effectively as the disposable litter tray.

Use a Forever Tray

You can use a forever litter tray in conjunction with the litter box as an alternative to the litter tray. It is made of high-quality plastic and completely leaks proof.

You can refill the tray with blue crystal litter every time and use it again and again. For this alternative to work perfectly with the litter box, make sure that-

  • The crystal litter is made of silica which is a must for using in ScoopFree self-cleaning litter box.
  • Check that if the crystal litter is in the right size for the forever tray.

If you mess up those 2 things, this alternative won’t work. If your crystal litter size is too big, they will be dragged into by the rake and it will create a mess. On the other hand, if the size is too small, the crystal may get into the motor and malfunction it. So, try to get the exact size crystal that came with the litter box.

Cleaning the forever litter tray takes a little bit of time. You need to get rid of the dirty litter, clean the tray with a hosepipe and make it completely dry off before adding new litter. If there is even a little bit of moisture left on the tray, the crystal will absorb it and get ruined.

Here is a good deal of forever litter tray that I have found on Amazon.

Use a litter bagger system

The litter bagger system is an effective yet costly alternative of using disposable litter trays. This system has a wooden platform with a hole in the middle. A bag is attached below the hole of the wooden platform.

The way this system works is this: when the automatic raking system goes through the liter, the clumps fall into the bag rather than getting stored in the waste compartment. It has its own permanent litter tray.

When you feel that it is time to change the litter, just scoop off the wet litter into the bag and refill the tray with new crystal litter. Take off the waste-filled bag and toss it into the dustbin.

This litter box is programmed to take care of everything. All you have to do is change the litter tray once a month.

Why is the green indicator flashing?

The green indicator flashes for two reasons:

  • Rapid flashes indicate that the cat is in the litter box and it is blocking the sensor. If the indicator is flashing rapidly and your cat isn’t in the litter box, then it indicates that urine or other waste are blocking the sensor.
  • Slow flashes indicate that the countdown mode is ON and the rake will start to sweep after 5, 10 or 20 minutes. Once the rake completes sweeping, the indicator should turn back to steady green.
