I have a Litter Robot MATERIALS question… what could I spray or rub on the black, rubber, liner bag that would prevent cat litter/urine clumps from sticking to it?
I have a cat with no known urinary infection issues who has a bad aim. She sprays the wall of the drum.
That would be OK if it wasn’t for the fact that the urine then flows down that wall and ends up forming a flat urine/litter pancake… securely glued to the black rubber bag below.
Result: when the drum rotates and the bag flexes the urine/litter pancake fails to release… or if it does release it’s so large that it can’t make it through the hatch below during rotation. To make matters worse the pancake(s) continue to increase in size with each cat visit!
Bottom line: my wonderful LR can no longer be trusted to watch over my cat for more than a day or two before I experience a delightful jam up!
Solutions Needed:
I’ve tried clear silicone spray on the black rubber surface to prevent sticking… works for a few days at best and I’m sure my cat will object eventually and shop elsewhere.
Is there another spray on material that will produce a non-stick barrier surface on the black rubber?
You could try searching for hydrophobic solutions like Liquid Off or NeverWet? I am no expert in the matter so I can’t guarantee it will work but that is what I would look for.
I’m with you I know this is old but this is an ongoing thing for me I just bought a litter robot and spent almost $1,000 on it just to go in there and pull huge clumps of cat urine bricks off of the nice liner how can it be trusted to do his job if I have to go in there and pull the clumps off the liner I might as well be scooping a box I’m just about to send it back for a refund if something don’t change or I don’t get some kind of answer from the company but they don’t seem to have an answer either does anybody have an answer of how you get urine clumps of litter to not stick to $1,000 litter robot for this shouldn’t be a problem you would think they would test this I’m totally frustrated totally so if anybody has any kind of idea of how to get this to stop please let me know I would almost send you a hug and a box.
Welcome to the RobotShop community! Thank you for your detailed message.
What you’re describing is a known issue for some cats who tend to urinate against the wall of the globe. Here are a few solutions we can suggest:
Non-stick coating:
We generally do not recommend silicone sprays or harsh chemicals, as they can damage the rubber surface over time or bother your cat. However, some users have had success applying food-grade PTFE (Teflon) film. It creates a smooth, non-toxic barrier. You can cut a strip and stick it to the lower area of the liner where the urine tends to collect.
Regular cleaning:
Even with preventive measures, we recommend cleaning the liner weekly with warm soapy water to help reduce sticking.
Physical splash guard:
Some users add a small splash shield inside the globe—such as a curved piece of plastic—to redirect urine away from the liner and reduce buildup.
Litter change:
If you’re using a very fine or sticky clumping litter (like some clay-based litters), it might worsen the issue. Switching to a less sticky clumping litter can help waste fall more easily during rotation.
Liner replacement:
If waste continues to stick heavily, we also suggest replacing the liner. Rubber can lose its non-stick properties over time due to exposure to corrosive substances like ammonia in cat urine.
Please don’t hesitate to reach out if you’d like help ordering a replacement liner or if you have any other questions.
