Purina Tidy Cats LightWeight Glade Clear Springs: Best for lighter lifting
- 17 lb container
- 21-day odor control when used as directed
- 50% lighter than leading clumping litter
- 99.9% dust free
This lightweight clumping litter is easier to carry while offering tight clumps, low dust and 21-day ammonia odor control when used as directed.
Pros
- Lightweight formula
- Tight clumps
- 99.9% dust free
Cons
- Scented formula
- Compatibility with Litter-Robot 5 should be confirmed before purchase
Purina Tidy Cats LightWeight Glade Clear Springs suits households where carrying heavy litter is difficult. The 17 lb container is 50% lighter than leading clumping litter, while the formula still forms light, tight, strong clumps.
A lighter container is easier to lift and pour slowly, which helps keep the fill level steady and avoid spills. Purina Tidy Cats also states 21-day ammonia odor control when used as directed, aimed at the sharp smell that builds up if a clump is missed.
The 99.9% dust-free claim may help reduce dust around the robot, and the Glade Clear Springs scent is noticeable. Scent can help in a small room, but it is a trade-off for cats sensitive to perfumed litter.
Transition gradually and watch the first cycles for intact clumps and normal use. Because Litter-Robot 5 compatibility is not specifically named in the product information, check the current machine guidance before switching.
Fresh Step Advanced Clean Paws Multi Cat: Best for reduced tracking
- Two 18.5 lb boxes
- Larger particles designed to stick less to paws
- 21-day odor control guarantee
- Low-dust formula
Larger particles are designed to stay in the box, while tight clumps, carbon and odor-control technology support frequent automatic cycles.
Pros
- Low tracking design
- Tight clumps
- Two-box pack
Cons
- Heavy 37 lb total pack
- Scented formula
Fresh Step Advanced Clean Paws Multi Cat is the strongest choice here for reducing litter around the exit. Its larger particles are designed to stick less to paws and stay in the litter box, which targets tracking directly.
Tracking is often the daily annoyance with an automatic box, because the cat leaves the globe and carries granules across the floor. Larger particles can be easier to trap with a mat and less likely to cling in damp paws.
The two-box pack contains 37 lb in total, so it gives you a useful reserve but requires more lifting than the lightweight options. You may prefer to store one box in a pantry and keep the other near the robot in a smaller scoop container.
Tight clumps support automatic waste removal, while carbon, Ammonia Block Technology and Febreze freshness support odor control. That combination is aimed at urine and fecal odors, which matters more in a multi-cat home where the box is used many times a day.
Fresh Step states that the formula offers 21-day odor control and has a low-dust design. Low dust helps during pouring and cycling, because dust can settle on nearby surfaces even when tracking is controlled.
Choose it when a clean floor matters more than avoiding scented litter. The Febreze freshness is part of the product identity, so households that want a neutral scent may prefer an unscented alternative.
For set-up, maintain a consistent depth and check the mat after the first few cycles. If granules still escape, the issue may be the exit area rather than the litter itself, and a larger mat can make a real difference.
Fresh Step Advanced Odor Shield Clumping Cat: Best for strong odor control
- Two 18.5 lb boxes
- 15-day odor control guarantee
- Activated charcoal
- Low-dust formula
Activated charcoal, Ammonia Block Technology and tight clumps make this a strong choice when odor control matters more than an unscented formula.
Pros
- Activated charcoal
- Tight clumps
- Low dust
Cons
- Heavy total pack
- Extra-strength scented formula
Fresh Step Advanced Odor Shield is the best fit when odor control is the deciding factor. The formula combines activated charcoal, Ammonia Block Technology and Febreze Gain scent with natural clay that forms tight clumps.
Activated charcoal is included to fight odors on contact, while Ammonia Block Technology targets ammonia from urine. Together they are designed for a busy box where waste may sit in the drawer between emptying days.
The two 18.5 lb boxes weigh 37 lb together. That is useful for maintaining a steady supply, but you may want to split the boxes into smaller storage loads.
Keeping one box sealed until the first is open also helps you judge whether your cat accepts the scent.
Fresh Step states that this formula provides 15-day odor control when used as directed. The period is shorter than some other picks here, so the benefit is intensity rather than the longest stated window.
It is low dust, but the extra-strength scent may not suit cats or people who prefer a neutral-smelling room. A strong fragrance can mask odors, yet it can also make a small space feel overpowering if the robot is close to a sleeping area.
Tight clumping is important for sifting, because a clump that crumbles can leave residue in the globe. Watch the first cycles closely and note whether clumps remain firm without sticking to the surface.
This option suits multi-cat households and homes where the litter box is in a living space. If odor is your main concern and you do not mind scent, it is a logical shortlist entry.
ARM & HAMMER Slide Platinum Easy Clean-Up: Best for robotic boxes
- 18 lb container
- Rock-hard clumps
- 99.9% dust free
- Described as suitable for robotic litter boxes
Rock-hard clumps and a non-stick formula suit automatic scooping, and the product is described as working in robotic litter boxes.
Pros
- Robotic-box compatibility stated
- Non-stick clumps
- 99.9% dust free
Cons
- Fresh scent
- No specific Litter-Robot 5 claim in the supplied product information
ARM & HAMMER Slide Platinum is the best overall match for an automatic litter box in this group. It is described as working in traditional and robotic litter boxes, and its non-stick formula forms rock-hard clumps that slide out for easier cleanup.
That non-stick behavior is valuable because sticking can make a robot work harder and leave residue behind. A clump that releases cleanly is easier for the sifting cycle to move into the waste drawer.
The 18 lb container also includes 99.9% dust-free performance and triple-action freshness that absorbs, locks and controls odors. Dust matters around electronics and on nearby floors, while odor control matters when the drawer is not emptied every day.
ARM & HAMMER describes the formula as having multi-cat strength, which suits a busy box. More cats means more urine volume, and a litter that weakens quickly can turn into soft clumps that break during cycling.
Use this as the first option if you want firm clumps and a product with robotic-box compatibility stated in its features. It is the clearest fit here for someone who wants to avoid guesswork about the litter type.
Still observe the first several cycles after changing litter, because clump behavior depends on fill depth and the amount of urine reaching the litter. A very deep fill or a cat that urinates in one spot can change how the clump forms.
Keep the waste drawer emptied on a regular schedule even with strong odor control. No litter can compensate for a drawer that is left until it is full, and a fresh scent should not be a reason to delay cleanup.
World's Best Cat Litter Multiple Cat: Best unscented natural option
- 32 lb bag
- Whole-kernel corn
- Unscented
- 99% dust free
This whole-kernel corn litter offers quick clumping, low dust and no artificial perfumes for households that prefer an unscented option.
Pros
- Unscented
- Whole-kernel corn
- Low tracking
Cons
- Must not be mixed with non-clumping litter
- Litter-Robot 5 compatibility should be confirmed
World's Best Cat Litter Multiple Cat is the best unscented choice here. It uses whole-kernel corn, contains no artificial perfumes and is described as 99% dust free with low tracking.
Corn litter suits households that prefer a plant-based formula and want to avoid added fragrance. It forms quick clumps for multiple cats, which can help the robot separate waste before it spreads through the litter bed.
The 32 lb bag is a substantial lift, so plan storage and consider decanting into a smaller bin near the robot. Transition slowly, starting with one-third new litter and increasing as your cat accepts it.
Do not mix it with non-clumping litter, or clumps may be uneven and harder to judge. For another model comparison, see our guide to the best kitty litter for Litter-Robot 4.
Keep the depth steady at 2 to 3 inches and check for soft clumps after the first days.
AWoHH 90 Pack Cat Litter Box Robot: Best for waste-drawer cleanup
- 90 transparent plastic bags
- 23.6 x 25.2 in size
- 9–11 gallon capacity
- Compatible with Litter-Robot 3, 4 and 5
These compatible replacement liners do not change the litter choice, but they can make the Litter-Robot 5 waste drawer easier to empty.
Pros
- 90-count pack
- Pre-separated bags
- Model 5 compatibility stated
Cons
- Not cat litter
- Compatible replacement part rather than an original brand accessory
AWoHH 90 Pack Cat Litter Box Robot bags are not litter, but they can make waste-drawer maintenance easier. The transparent plastic bags are designed for Litter-Robot 5, 4 and 3, with a 9–11 gallon capacity and a 90-count pack.
A liner that fits well makes removal faster and reduces the chance that waste sticks to the drawer. Each bag is pre-separated, so you can pull out one liner without tearing it from a roll.
The bags measure 23.6 x 25.2 in, are described as heavy duty, and hold up to 22 lb. Transparency also helps you see the contents before lifting the bag and judge whether the drawer is full.
Use these with whichever clumping litter you choose, as they do not change clumping or sifting. Fold or tuck the edges as directed for your model, since folds can catch and make removal messy.
Purina Tidy Cats Clumping Cat Litter: Best for large litter reserves
- 38 lb package
- 10-day odor control when used as directed
- Moisture-locking technology
- 99.9% less dust
The 38 lb package suits homes that want a larger supply of clumping litter, with tight clumps and 10-day odor control when used as directed.
Pros
- Large package
- Tight clumps
- Low-dust pour
Cons
- Heavy to move
- Scented formula
Purina Tidy Cats Clumping Cat Litter suits households that want a large supply in one package. The 38 lb package uses clay that forms strong, tight clumps and includes moisture-locking technology for single-cat or multi-cat use.
A larger package reduces how often you reorder, which helps busy homes. The trade-off is storage and lifting, so decant into a smaller container near the robot for daily topping up.
Moisture locking keeps urine from spreading through the litter bed, where spread can make clumps larger and softer. Purina Tidy Cats states 10-day odor control when used as directed, so regular drawer emptying still matters.
It also claims 99.9% less dust, which may keep the area around the robot cleaner during refills. Less dust can mean less wiping of nearby surfaces, especially in a small bathroom.
Its scented formula and lack of a specific Litter-Robot 5 compatibility statement make it less targeted than Slide Platinum. Keep the fill depth consistent and watch clump strength during the first week.
Scoop Away Advanced Multi Cat Clumping Cat: Best for contact odor control
- Two 18.5 lb boxes
- 7-day odor control guarantee
- 99.9% dust free
- Ultra-strong clumps
This multi-cat clay litter locks in liquid and odor on contact, forming strong clumps for automatic waste removal and daily cleanup.
Pros
- Ultra-strong clumps
- 99.9% dust free
- Two-box pack
Cons
- Shorter stated odor-control period
- Scented formula
Scoop Away Advanced Multi Cat suits households that want strong clumps and a two-box supply. The clay formula locks in liquid and odor on contact, creating ultra-strong clumps for scooping.
Locking in liquid and odor early helps the clump stay intact while the robot separates waste. The pack contains two 18.5 lb boxes, or 37 lb total, so plan storage before it arrives.
Scoop Away describes the litter as 99.9% dust free and formulated for multi-cat boxes. Low dust helps with pouring and keeping nearby floors cleaner.
Its stated odor-control guarantee is 7 days, shorter than several other picks. The Meadow Fresh scent may appeal if you prefer fragrance, but transition slowly by sprinkling a thin layer over your current litter first.
Check that clumps do not become too large for the waste drawer during set-up.
ARM & HAMMER HardBall Clumping Cat Litter: Best for lightweight grain litter
- 14.5 lb bag
- American-grown sorghum grain
- 99.9% dust free
- Up to 20 days of odor control
The sorghum grain formula offers lightweight handling, low dust and compact clumps for households considering a non-clay alternative.
Pros
- Lightweight bag
- 99.9% dust free
- Compact clumps
Cons
- Compatibility with Litter-Robot 5 should be confirmed
- Scented formula
ARM & HAMMER HardBall is the best lightweight grain option in this roundup. Its American-grown sorghum grain formula weighs 14.5 lb, forms ultra-compact clumps and is described as 99.9% dust free.
Sorghum offers an alternative for households that want to move away from traditional clay. The grain formula is aimed at people who like the idea of a plant-based litter without switching to corn.
The product combines lightweight handling with a Garden Bloom scent and odor control for up to 20 days. A smaller bag is easier to carry from a store or storage area, which can matter if you have stairs or limited strength.
That may suit a household that wants less weight without choosing a clay formula. It can also suit a single-cat home where a large bag would last a long time and become awkward to move.
Ultra-compact clumps are a positive for automatic sifting, because the waste can be removed without taking too much clean litter with it. Compact clumps also make the waste drawer easier to empty.
Because the information does not specifically confirm Litter-Robot 5 compatibility, verify the current machine guidance before switching. Grain litters can behave differently from clay, so the first cycles are an important test.
Watch whether the clumps stay intact during the automatic cycle. If they crumble or stick, the issue may be fill depth, cat habits, or the litter type itself.
The Garden Bloom scent is described as refreshing without overpowering small spaces. Even so, scent remains a personal choice, and an unscented option may be better if fragrance bothers your cat or your household.
What makes litter suitable for Litter-Robot 5?
Firm clumping is the most important feature because the machine needs to separate waste from reusable litter. For another self-cleaning system, see litter for PetSafe self-cleaning litter boxes.
A clump that breaks apart can leave wet material behind or send clean litter into the waste drawer.
Low dust is the next useful trait. Dust can settle around the unit during pouring and cycling, so a low-dust formula may reduce surface cleanup.
Particle size also affects tracking and sifting. Fresh Step Clean Paws is designed around larger particles that stick less to paws, while corn and sorghum formulas offer alternatives to traditional clay.
Scent is a personal choice rather than a compatibility test. Scented formulas may help mask odors, but an unscented option such as World's Best can be a better fit for cats or people who dislike fragrance.
Should you use clay, corn or sorghum litter?
Clumping clay offers the widest range of choices in this roundup, including Slide Platinum, Fresh Step, Purina Tidy Cats and Scoop Away. These products focus on tight clumps, odor control and automatic cleanup.
Clay forms familiar clumps that sift predictably, which matters when the machine decides what to remove. Corn and sorghum provide plant-based alternatives, with World's Best using whole-kernel corn and ARM & HAMMER HardBall using American-grown sorghum grain.
Plant-based litters appeal to households that prefer renewable ingredients or want to avoid clay dust. Their textures differ from clay, so cats may react to them more.
The right material depends on how your cat uses the box, not only the label. A cat that urinates in one spot creates a different challenge from one that scratches across the globe.
Change litter slowly instead of filling the robot at once, so you can judge clump strength and your cat can accept the texture and scent. If you're considering PrettyLitter, read can PrettyLitter be used in a Litter-Robot before changing systems.
Test one change at a time and note tracking, odor and clump quality during the first week.
How do you reduce tracking and cleanup?
Use a low-dust litter, keep the fill level consistent and place a mat directly outside the robot. Clean Paws is the most targeted option here because its larger particles are designed to remain in the box.
Tracking usually starts at the exit, where paws carry granules onto the floor. A mat placed where the cat actually steps can catch more litter than one placed a few inches away.
Particle size matters because smaller granules can cling more easily and travel farther. Larger particles may still escape, but they are often easier to sweep and less likely to work into carpet.
Inspect the area around the exit after each cycle during the first few days with a new litter. If tracking increases, try a deep-groove mat that traps granules instead of pushing them to the edges.
Keep the fill level consistent because too little litter can change clump formation and too much can increase spillover. Sweeping a small area daily is often more effective than a weekly deep clean.
Our guide to what a litter tray liner is used for explains why liner placement matters. Keep the liner fitted without folds, so the drawer slides out cleanly.
Judge tracking and scent separately, since a scented litter may smell fresher while still leaving granules.
Can non-clumping litter work in Litter-Robot 5?
Non-clumping litter is usually a poor choice for an automatic sifting box because it does not bind urine into a removable mass. The machine may remove too much clean litter or leave damp material behind.
The robot is designed to separate solid waste from litter that can be reused, and non-clumping material does not form the clean boundary it needs. Clumping formulas form a separate piece that can move into the waste drawer while most litter stays in the globe.
If you prefer non-clumping litter, check the Litter-Robot 5 instructions before using it and watch the first cycles closely. Some households may accept more frequent full changes, but that defeats much of the purpose of an automatic box.
Non-clumping litter can absorb moisture, but saturated litter often needs a complete change rather than a simple scoop. See our guide to how non-clumping litter works for cat owners for those trade-offs.
Damp litter that cannot be removed can also smell stronger over time, and cycling cannot create a clump the litter does not form.
Which litter is best for Litter-Robot 5?
ARM & HAMMER Slide Platinum is the best starting point because it is described as suitable for robotic litter boxes and forms rock-hard, non-stick clumps. Pick Fresh Step Clean Paws if tracking is your main problem, or World's Best if you want unscented corn litter.
Those three choices cover the most common priorities. Slide Platinum targets automatic cleanup, Clean Paws targets the floor around the exit, and World's Best targets scent avoidance.
Choose Purina Tidy Cats LightWeight when carrying litter is the main concern, since its lighter container makes restocking easier. Choose Fresh Step Advanced Odor Shield or Purina Tidy Cats Glade when scented odor control matters most.
For another generation comparison, see our guide to the best litter for Litter-Robot 3.
Whichever formula you choose, transition slowly, keep the fill depth steady and check the first cycles for complete clumps. Complete clumps in the drawer and a clean globe are better signs than a fresh scent alone.
If tracking increases, adjust the mat and exit area before abandoning the litter. If clumps break apart, consider fill depth and urine volume.

Frequently asked questions
What litter can be used in Litter-Robot 5?
Use a clumping litter that forms firm clumps and can pass through the unit's sifting process. Clay, corn and other clumping formulas may be options, but check the Litter-Robot 5 instructions and transition your cat slowly.
Avoid changing litter and cycle settings at the same time, because that makes it harder to identify the cause of missed clumps or tracking.
Is ARM & HAMMER Slide Platinum suitable for Litter-Robot 5?
ARM & HAMMER Slide Platinum is described as working in robotic litter boxes and forms rock-hard, scoopable clumps. That makes it the clearest fit in this group for an automatic box.
Confirm the current Litter-Robot 5 guidance before buying, then watch for clumps that break apart or stick during the first few cycles.
Can non-clumping litter be used in Litter-Robot 5?
Non-clumping litter is usually a poor match for an automatic sifting box because urine is not bound into a removable clump. The machine may leave wet material behind or remove clean litter with waste.
Read our guide to how non-clumping litter works if you're deciding between litter types.
How do you reduce tracking from Litter-Robot 5?
Choose a low-dust litter with particles designed to stay in the box, place a mat at the exit and scoop stray pieces from nearby floors. Fresh Step Clean Paws is designed to stick less to paws and stay in the litter box.
A mat cannot stop every granule, so keep the area around the unit easy to sweep.
