Litter Robot 4 - Purchased May24 - Australia

We have been using the litter robot just for couple of weeks now. At $1575 AUD it is the most expensive and shitter we have ever bought !! So obviously the expectation for it to perform well is very high. It came with the step, guard and 3 litter bag and a filter.

Reason we went with this compared to cheaper models is because we have 2 bigs cats. A ragdoll and a mainecoon. And we were under the impression it was the best one sizewise for these big floofs

1.Setting up was pretty easy.
2.It took about 1 week for both cats to get use to it and fully using it.
3.Emptying litter box dropped from 4 times a day to one time a week!


1.Where do I start!!
Litter choices- we are a tofu litter household and we and the cat both love it. The sieve of this robot is too small to filter tofu litter through and so many people are either cutting the sieve or grind the tofu litter to make it compatible. The lenght people will go to to keep their pets happy is to be admired. And this is something that litter robbot should address. As there are good clumping tofu litter on the marker. They should not force people to use clay litter or buy their tofu litter which by the way have some terrible reviews.since the inner glove is fully removable they should come up with a replacement glove with a sieve that is mainstream tofu litter compatible and allow customer to swap the globe out in a near future.

2.The litter guard is of hardly any use. As it does a bad job of stopping litter falling out. So they have come up with a shield to solve this. Again they should offer existing customer a discount voucher to purchase this to fix this current issue.

3. Globe hight.
The litter robot 4 is quite bulky in size but my mainecoon is quite tall and she finds it cramped to use.As a result she sits at the very edge of the entrance to pee or poo. As if she goes further in her face and head touches the sides.
As a result sometimes her bum will be hanging out and her poop will drop on thr floor. Because she pee at rhe edge when the litter cycles around most litter is dump in the middle and not right the the edges so the clumping is not that efficient at the edges because of this.

Litter robot should consider doing an open top litter box for larger breed so that they feel less cramped to move around. A bit like the Neasaka design that swings back to front instead of round. This will fix this issue for larger breeds. Unfortunately Neasaka do not ship to Australia unfortunately that would have been my choice.

4. The scale.
When my cat sits at the edge it does not register her weight properly.

My ragdoll who on the otherside uses the robot properly and go right in to pee or poo even his weight has not been registering properly now. I have raise this issue with the company and perform a reset. Will have to keep a close eye on this one.

5. Litter level.
Despite filling the litter to the mark and cycling sometimes the app will still say not at optimal and when you top up again and cycle. It then dump the excess Despite still saying not optimal level.

There should he a display ontop of the globe foe litter level as one doesn't always walk around with their phone to check the litter level. This should be something that you can see looking at thr robot just like the light changes blue when bin is full. It should also have an indicator light for litter level.

5. List of litter selection.

They now have a new feature on the app where you can select the brand and type of litter. This option should further be enhance for other litter option.

People should be able too add the litter name and country. This will also enhance their current listing database to capture maximum data and selection to chose from.

5. Since the app already captures the weight and time. They should add a dash board feature that enables people to see a summary of the time their cats uses the toilet and weight.

This product have still some way to go to make it an amazing gadget. And since there is a demand fir improvement the company should consider thr feedbacks
And enhance this product further.

Thank you for your feedback, which is always appreciated.
Addressing your points:
1. The Litter-Robot has been designed to work primarily with clay clumping litter as you are aware. Good quality clay clumping litter works best as it locks in uric acid (pee smell) better than plant based litters such as Tofu. Cat Evolution Tofu litter has been designed by request as a tofu that will work with the Litter-Robot, and reviews are 1 star from clay users, and 5 star from tofu users which reflects the difference in the 2 types of litter material and performance. There is no requirement to use any of the litters on the Cat Evolution website, as the Litter-Robot is designed to use a range of clay clumping litters, and some non-clay if the grain size works with the sieve although good clumping clay is the recommended litter type for the best experience. Possible septum or sieve size options is a suggestion that the Manufacturer Whisker may well be developing, as customer feedback is always welcome.
2. Guard. Developed to help keep litter in and to direct any inside front sprayed urine down into the globe. The Shield is a new development as an option for customers with cats that toss litter out of the opening, as an accessory.
3. Globe size. The Litter-Robot has the largest available globe for automatic litter boxes. Designed for the larger cats to turn and face forward so they are fully on the litter bed with heads in the open air. Sometimes some training is required to help with the issue. If not successful or suitable, there is a 90 day return guarantee (ensure you keep the packaging and return courier is at purchaser cost). Open top litter boxes do not contain litter as well, but do have the advantage if your cats are not comfortable in a more enclosed globe.
4. The Scale. The cat sensors are located in the 4 feet of the Litter-Robot 4, and need to be on a level hard surface for more accurate measurement. The cat does need to enter fully onto the litter bed for a good downward pressure to measure weight. Accurate weight measurement is not needed for the Litter-Robot to register use and cycle to clean. Whisker is also improving the APP ongoing to provide better and more accurate reporting and functionality.
5. Litter level. There is a line on the globe liner to make top up and level check easy when you attend to empty and top up. In addition, the APP provides information. Whisker are improving the APP for better and more functionality so ensure your app is set to auto update to take advantage of any improvements.
6. Litter brand and country are an excellent suggestion for customer to be able to add, given the most recent improvement to the APP by Whisker. Also Dashboard suggestion for app improvement, which will be provided to Whisker, who are generally responsive to good suggestions and regularly work to improve the experience.

Thank you again for your suggestions, and I trust the additional information will assist with your understanding and use of the Litter-Robot 4 at this time.

Anthony Smith
Next Level Cat Toilet

I have a couple of Litter Robot IIIs which I thought were awesome and they are. But the Litter Robot 4 is next level. It looks great and I can't believe how quiet it is compared to the LR3s. The only time I even know when it is cycling is when I think that I can hear rain but it's only the sound of the litter being moved into the pocket so that the clumps can go down to the waste draw. And there is no smell coming from the Lr4 whereas I could sometimes smell the LR3.

With the ability to weigh my 2 cats and tell me who is using it and when is a great feature. Also the ability to show me how much litter is in the robot and letting me know when I need to top it up is also a great feature too.

I highly recommend this as a must have item for your cats and they will love you for it and so will everyone else in the house.

I want another one! Thi has been such a huge time save

It took about two weeks for my five cats to transition to using this, and it has been absolutely brilliant. This has saved me so much time and effort from daily scoops and emptying bins, and was worth every dollar. I am actually thinking of getting a second one to move away from any of my manual litters in the home and will be saving up for it! The app is also extremely handy - you can clearly see which cat is using the litter and when. I absolutely recommend.
The sales support was also fantastic, I received a call as soon as I sent an enquiry through (but unfortunately never got to speak to Mary directly because of so many meetings in my calendar) and was also given a very informative and detailed list of which litters to use. I appreciate how the team always provide colesworth or ALDI alternatives to the accessories needed and aren't just trying to push their products onto you. They care, and honestly this has been one of the best customer service experiences I've had in my life.
