9 Best Litter-Robot 4 Waste Drawer Liners (November 2026)
The best Litter-Robot 4 waste drawer liners include the LotuFlor Cat Litter Box Liner Compatible for reinforced bottoms, the Elzrghs 100 Pack Drawstring Cat Litter Box for drawstring disposal, and the JOCCIK Drawstring Litter Box Liners Compatible for opaque bags.
On this page (4 sections)
The best litter robot 4 waste drawer liners for most homes are LotuFlor's heavy-duty bags, with a strengthened bottom and a 9-gallon capacity.
That pick suits single-cat homes and multi-cat homes where a full bag can feel heavy when you lift it out.
Choose Elzrghs for 100 drawstring bags, JOCCIK for opaque white liners, or NXPPYY if you want the largest pack in this group.
A good waste drawer liner needs to fit the drawer, hold the amount of waste your cat produces and come out without spilling.
Fit matters first because a liner that shifts can catch on the drawer path or bunch to one side.
Capacity matters next because a bag that is too small forces more frequent changes, while a bag that is too large can be awkward to carry when full.
Closure style also shapes daily use, since a drawstring can make it easier to seal the bag before you lift it.
For liners made for Modkat boxes, compare Modkat litter box liners.
The picks below compare capacity, bag count, material, closure style and compatibility.
Those details help you match the liner to a Litter-Robot 4, a Litter-Robot 3, or another self-cleaning setup without guessing from the package name alone.
For broader cleanup advice, start with our litter disposal system guide.
If you're also replacing the odor filter, see our guide to the best litter robot 4 carbon filters.
Read the size notes closely before you order, since small differences in width or length can change how a liner sits on the rim.
Check the pack count against how often you empty the drawer, because a larger count helps most when waste changes are routine.
Keep spare liners near the box so a full bag does not sit waiting while you search for the next one.

Which Litter-Robot 4 waste drawer liners are best?
LotuFlor is the best overall choice because its heavy-duty bag has a strengthened bottom and a 9-gallon capacity.
That combination suits owners who want the base of the bag to feel steadier when the drawer holds a normal load of waste.
Elzrghs, JOCCIK and xuepett are close alternatives when drawstrings, opaque bags or a larger pack matter more.
Elzrghs is useful when you want many pre-separated bags and a simple pull-to-close routine.
JOCCIK suits homes that prefer not to see the waste through the bag during removal.
xuepett suits buyers who want a larger count on hand and do not mind checking the drawer measurement first.
We compared the stated sizes, capacities, counts, materials and closure features.
That comparison keeps the focus on practical details such as how the bag is separated, how it closes and whether it is described for Litter-Robot 3, Litter-Robot 4 or both.
Our score weighs specs, features and buyer feedback against what you're shopping for.
A high score here does not replace a fit check, because liner dimensions and drawer tabs can still differ by model.
Use the rankings as a shortlist, then confirm the exact bag size and closure before you buy.

Best litter robot 4 waste drawer liners by use
The right liner depends on how often you empty the drawer and what makes disposal easiest for you.
A 50-count bag may suit a low-use box, while a 120-count or 160-count pack can reduce restocking.
Single-cat homes often stretch a pack further, while multi-cat homes can go through liners faster even with a large capacity.
Think about your storage space too, because rolls and boxed bags need different shelf or cupboard room.
Think about the carry-out step as well, since a sealed bag that is easy to lift can save more time than a slightly larger capacity.
The product write-ups below break down those trade-offs by bag style, size and model fit.
LotuFlor Cat Litter Box Liner Compatible: Best for reinforced bottoms
- 50-count pack
- 9-gallon capacity
- Strengthened bottom
- Compatible with Litter-Robot 3 and 4
LotuFlor suits Litter-Robot 4 owners who want a heavy-duty liner with a strengthened bottom. The 9-gallon bags are unscented and designed for quick replacement.
Pros
- Strengthened bottom
- 9-gallon capacity
- Point-to-break bags
Cons
- The title says 50 pack while a bullet says 75 liners
LotuFlor is the strongest overall pick for Litter-Robot 4 owners who worry about the bottom of a full waste bag. The bag has a strengthened bottom and is described as heavy duty, with a 9-gallon capacity for animal waste.
The pack has a point-to-break design that makes individual bags easier to separate. The bags are unscented and white, so they avoid adding fragrance during disposal.
For installation, roll the edges down several times, start at the back of the drawer and attach the rolled edge to the 4 liner tabs. This setup detail matters because a liner that is not secured can shift during use.
One detail needs attention before ordering: the title states a 50 pack, while one product bullet says 75 liners. Check the current pack details if the exact count affects your choice.
Buy it for a reinforced bottom and 9-gallon capacity. It is the best fit here for owners who put extra weight on a sturdy base.
Elzrghs 100 Pack Drawstring Cat Litter Box: Best for drawstring disposal
- 100-count pack
- 25 x 16 in bags
- 22-pound capacity
- LDPE material
Elzrghs is a strong choice if you want a large pack of pre-separated drawstring bags. Its stated 22-pound capacity and LDPE construction suit regular waste-drawer changes.
Pros
- 100 bags
- Drawstring closure
- Pre-separated bags
Cons
- Measure your drawer before ordering
Elzrghs suits households that want 100 pre-separated drawstring bags for Litter-Robot 3 or 4. Each bag measures 25 x 16 inches and is made from low-density polyethylene.
The drawstring helps close the bag before you lift it from the drawer. If you use a waste pail too, compare Litter Genie vs Easy Roll before choosing a disposal setup.
Elzrghs gives a stated capacity of 22 pounds, which is useful for readers comparing load limits rather than gallons.
The bags are designed to resist tears and leaks, and they are unscented. Their white color keeps the appearance simple, while the drawstring reduces the need to tie the bag separately.
Measure your drawer before ordering because a stated compatibility range does not guarantee the same fit in every setup. The large count makes this a practical choice for frequent waste changes.
Buy it for 100 drawstring bags and a stated 22-pound capacity.
JOCCIK Drawstring Litter Box Liners Compatible: Best for opaque bags
- 50-count pack
- 9-gallon capacity
- Opaque white design
- Extra-thick LDPE
JOCCIK fits buyers who prefer an opaque white waste bag and a drawstring closure. The bags are unscented, fragrance free and described as compatible with Litter-Robot 3 and 4.
Pros
- Opaque white bags
- Drawstring handles
- Extra-thick LDPE
Cons
- Not recommended for standard cat boxes
JOCCIK is the best option for owners who prefer opaque white waste bags.
Its 50 bags have a 9-gallon capacity, are made from extra-thick LDPE and use durable drawstring handles.
That mix suits households where discretion matters, because the white plastic hides the contents better than a clear bag when you carry it out.
The opaque design keeps the waste out of view during removal, which can make the job feel cleaner in shared living spaces.
The bags are also unscented and fragrance free, which suits homes where added scent is unwanted.
Extra-thick LDPE is the key material detail here, since thickness can help the bag resist tears when clumps shift inside.
JOCCIK describes these bags as compatible with Litter-Robot 3 and 4 and with most automatic or self-cleaning litter box drawers.
It does not recommend them for standard cat boxes, so keep the intended drawer style in mind.
That limit matters if you plan to use the same bags in a regular open-top litter box as well.
The drawstring gives you a simple lift-and-close routine.
Pull the handles, lift the bag carefully and check that the bottom is clear before carrying it away.
For setup, keep the liner loose enough to receive waste without pulling the edges off the drawer.
A 50-count pack is a mid-size choice, so it works best when you do not need a bulk supply but want opaque bags with a drawstring.
xuepett 120 Pack Cat Litter Box Liners: Best for a large pack
- 120-count pack
- 25.2 x 15.7 in size
- 22-gallon capacity
- Perforated tear lines
xuepett is made for owners who want 120 liners on hand. Its drawstring closure, perforated tear lines and stated Litter-Robot 3 and 4 compatibility support faster changes.
Pros
- 120 bags
- Drawstring closure
- Perforated tear lines
Cons
- Check that the drawer length plus width is under 24 in
xuepett is made for owners who want a 120-count pack and a drawstring closure.
The bags measure 25.2 x 15.7 inches, have a stated 22-gallon capacity and are designed for Litter-Robot 3 and 4.
That large count suits homes that prefer to restock less often and keep a steady supply near the litter box.
Perforated tear lines help you separate each bag before installation.
The drawstring then gives you a closure to pull when the bag needs to come out.
The large stated capacity can mean fewer interruptions, but fit still comes first.
xuepett says the length plus width of the litter box should be less than 24 inches, so measure before choosing this option.
That measurement check is worth doing slowly, because a liner that is too wide can fold awkwardly around the rim.
The reinforced construction is intended to handle digging and scratching during normal drawer use.
The LB-120 model is a clear identifier if you need to compare the same product later.
For daily care, store the pack where the perforations stay clean and dry, since torn edges are easier to handle when the bags are not dusty.
This option is a good match when a big pack and a drawstring matter more than a compact box.
NXPPYY 160 Count Cat Litter Box Liners: Best for frequent changes
- 160-count pack
- 10 to 12-gallon capacity
- 25.19 x 15.7 in size
- Drawstring handles
NXPPYY is the pick for households that want the largest count in this group. The blue plastic bags hold 10 to 12 gallons and include easy-lift drawstring handles.
Pros
- 160 bags
- 10 to 12-gallon capacity
- Compact rolls
Cons
- Blue bags are not opaque white
NXPPYY is the best choice for households that want the largest pack in this roundup.
It includes 160 blue plastic liners, each measuring 25.19 x 15.7 inches and holding 10 to 12 gallons.
That count suits multi-cat homes and busy households where waste drawer changes happen often enough that restocking becomes a chore.
The drawstring handles are designed for lifting and tying the bag before disposal.
NXPPYY describes the liners as leakproof and scratch resistant, with thick plastic that suits clumping litter.
The stated capacity helps explain the value of the large pack, because fewer changes are needed when each bag holds more waste.
Compact rolls make the 160 bags easier to store than a loose pile of liners.
That roll format also keeps the supply tidy in a cupboard, drawer or utility shelf near the litter box.
The bags are unscented, but their blue color is different from the white and clear options here.
NXPPYY is designed for Litter-Robot 3 and 4 and other self-cleaning cat litter boxes.
Use the measurements as your final fit check, especially if the drawer has a tight rim or tabs.
If your drawer edges fold over easily, a snug liner will stay in place better than one that is stretched too tight.
Good kitty CO Waste drawer liners compatible: Best for 10-gallon capacity
- 50-count pack
- 10-gallon capacity
- Unscented plastic bags
- Compatible with Litter-Robot
Good kitty CO gives Litter-Robot owners a simple 50-count option with 10-gallon capacity. It also fits SCOOPER YOUNG and SCOOPER LUXURY PRO, but not SCOOPER SE.
Pros
- 10-gallon capacity
- 50 bags
- Unscented
Cons
- Not suitable for SCOOPER SE
Good kitty CO offers a straightforward 10-gallon liner for Litter-Robot owners.
The 50-count pack uses unscented plastic bags for animal waste and is also described as compatible with SCOOPER YOUNG and SCOOPER LUXURY PRO.
That wider compatibility can help if you use more than one automatic litter box brand in the same home.
The extra compatibility can also help when you move a liner supply between boxes, as long as each drawer shape accepts the bag.
It is not suitable for SCOOPER SE, so that model exclusion matters when you are comparing waste drawer bags.
Good kitty CO describes the bags as strong, leakproof and able to contain odors.
Those claims make the option worth considering when you want a basic 10-gallon bag without a long feature list.
The white color keeps the bag familiar and easy to identify.
Check the drawer shape and liner fit before relying on the stated compatibility.
A simple bag like this suits owners who value a plain routine over extra features such as perforations or roll packing.
For care, keep the unused bags dry and folded so the plastic stays smooth and easy to fit.
This is a sensible pick when a 10-gallon capacity and a modest 50-count pack match your change schedule.
Dilcare Cat Litter Box Liners for Robot: Best for Robot 3, 4 and 5
- 80-count pack
- Four rolls
- 25.19 x 15.7 in size
- Drawstring closure
Dilcare is useful if you may move between Litter-Robot 3, 4 and 5. The 80 bags come on 4 rolls and use a drawstring closure for lifting and disposal.
Pros
- Fits Robot 3, 4 and 5
- 80 bags
- Four rolls
Cons
- The stated capacity is 10 pounds
Dilcare is the best fit for households that may use Litter-Robot 3, 4 or 5.
The pack has 80 bags on 4 rolls, with each bag measuring 25.19 x 15.7 inches.
That broad model coverage suits homes that own more than one Robot version or may upgrade later.
The heavy-duty plastic is designed to resist punctures and leaks.
A drawstring closure helps seal the waste bag after removal, while the roll format keeps replacement bags together in storage.
Dilcare describes the liners as BPA-free, non-toxic and food-grade safe plastic.
The product data gives a stated capacity of 10 pounds, so compare that measure with your usual waste volume before choosing it.
That pound-based measure is different from gallon ratings, so use it as a guide to load weight rather than liquid volume.
The broad model compatibility is the main reason to choose Dilcare over a Litter-Robot 4-only option.
It can also reduce the need to change bag types if you upgrade equipment later.
For setup, let the bag sit naturally in the drawer and avoid pulling the plastic too tight across the opening.
Four rolls are easy to split across storage spots, which can help if you keep supplies in more than one room.
HEIDBER Drawstring Litter Liner Bags 100 Pack-Cat: Best for separate bags
- 100-count pack
- 24.4 x 15.75 in size
- 5.5-gallon capacity
- LDPE material
HEIDBER suits buyers who want 100 individually separated bags that can also fit some household and kitchen trash cans. Its 5.5-gallon capacity is smaller than most picks here.
Pros
- 100 separate bags
- Drawstring design
- LDPE material
Cons
- Smaller 5.5-gallon capacity
HEIDBER suits buyers who prefer 100 separate bags that can be pulled from the box one at a time.
The liners measure 24.4 x 15.75 inches and use LDPE material with a drawstring design.
That separate-bag format suits owners who do not want to tear or cut each liner from a roll.
The stated 5.5-gallon capacity is smaller than most other choices in this roundup.
That can work for lighter waste loads, but households that wait longer between changes may prefer a larger bag.
HEIDBER describes the bags as compatible with Robot 3 and Robot 4, and also suitable for some household and kitchen trash cans.
Measure the drawer before ordering because the intended uses cover more than one container type.
The white, unscented bags are leak resistant and tear resistant according to the product details.
A 1-year warranty description is also included, but review the current terms before relying on it.
For daily use, pull one bag fully free before fitting it, since a partially separated liner can twist around the rim.
This option is a good fit when easy separation and a drawstring matter more than maximum capacity.
Decalare Litter Box Liners for Litter R.o.bot: Best for transparent bags
- 120-count pack
- 25.2 x 23.6 in size
- 9 to 11-gallon capacity
- Transparent plastic
Decalare is designed for owners who want transparent, pre-separated bags and broad Litter-Robot compatibility. Its stated capacity reaches 11 gallons and supports up to 23 pounds per bag.
Pros
- 120 bags
- Transparent design
- Fits Litter-Robot 3, 4 and 5
Cons
- Waste remains visible through the bag
Decalare is the best choice for owners who want transparent bags with broad model compatibility.
The 120-count pack fits Litter-Robot 3, 4 and 5, with a stated 9 to 11-gallon capacity.
That range suits homes that want one liner style across several Robot models.
The bags measure 25.2 x 23.6 inches and are designed to stay in place during use.
Their transparent design may let an automatic litter box sensor read waste levels, while also making the contents visible to you.
Decalare gives a support limit of up to 23 pounds per bag.
The bags are extra thick, leakproof and tear resistant according to the product details, with an unscented plastic material.
For Litter-Robot 4, fold the liner edges over the drawer rim.
For Litter-Robot 3, insert the rolled edges into the drawer tabs.
That difference makes model-specific setup worth checking before you fit the first bag.
Keep the plastic smooth at the bottom of the drawer, because folds can trap waste and make removal messier.
Transparency is the main trade-off here, since you gain visibility but lose the privacy of an opaque bag.
How do you choose Litter-Robot 4 liner bags?
Choose Litter-Robot 4 liner bags by drawer fit first, then compare capacity, closure and pack count. A bag that holds more waste is not useful if its edges do not stay on the drawer rim.
What size should Litter-Robot 4 bags be?
There is no single size across these Litter-Robot 4 bags. The products here range from 24.4 x 15.75 inches to 25.2 x 23.6 inches, so measure the drawer and compare the dimensions before ordering.
Some bags state gallon capacity, while others state pounds or both. Treat those measures as product-specific rather than interchangeable.
Are drawstring litter robot 4 bags easier to remove?
Drawstring litter robot 4 bags are usually easier to close and lift because the handles pull the opening together. Elzrghs, JOCCIK, xuepett, NXPPYY, Dilcare and HEIDBER all use drawstring designs.
A standard liner can still be easy to remove when its edge is secured correctly. The main difference is how you close the bag before carrying it to the trash.
How do you replace a Litter-Robot 4 waste drawer liner?
To replace a Litter-Robot 4 waste drawer liner, remove the full bag carefully, clean the drawer if needed and fit the new liner over the drawer rim. Keep the liner loose enough to receive waste without pulling it out of position.
Avoid stretching the plastic tightly across the opening. Check that the bottom reaches the drawer and that no part of the liner blocks the drawer path.
For related waste-handling information, read How Does an Automatic Litter Box Dispose of Waste? and How Do Automatic Litter Boxes Separate Waste from Litter?.
Should you use a liner roll or pre-separated bags?
Choose rolls when compact storage matters, and choose pre-separated bags when you want to pull out one liner without tearing it.
LotuFlor uses roll packing with a cutting line, while Elzrghs, HEIDBER and Decalare describe pre-separated bags.
Rolls can be neater in a narrow cupboard, while boxed or separated bags can be quicker to grab during a busy morning.
The best choice depends on where you store supplies and how quickly you want to prepare the next change.
Keep spare liners near the litter box so replacement does not get delayed.
That small habit helps most in multi-cat homes, where a full drawer can fill sooner than you expect.
For setup, fit the new liner loosely in the drawer and check that the bottom reaches the base without bunching.
Avoid stretching the plastic tightly across the opening, since tension can pull the edges inward during use.
If you also use a Litter Genie, our guide explains how to refill Litter Genie bags.
For other Robot models, compare our picks for the best litter robot bags and best litter robot 5 bags.
Those guides can help when your cleaning setup includes more than one brand or model.
Which litter robot 4 trash bags should you buy?
Pick LotuFlor if a strengthened bottom and 9-gallon capacity matter most.
Choose Elzrghs for 100 drawstring bags, xuepett for 120 bags with a stated 22-gallon capacity, or NXPPYY for the largest 160-count pack.
Pick JOCCIK if you prefer opaque white bags that hide the waste during removal.
Pick Good kitty CO if a simple 10-gallon, 50-count option fits your routine and drawer shape.
If you want one style that covers Litter-Robot 3, 4 and 5, Dilcare or Decalare is a better match.
Dilcare suits buyers who want rolls and a drawstring across those models.
Decalare suits buyers who want transparent bags and broad Robot compatibility.
For the final choice, compare the exact liner dimensions with your drawer before ordering.
Then choose the closure and count that fit your cleaning routine, your storage space and how often you empty the drawer.
That final check should prevent most fit problems and make every replacement faster.

Frequently asked questions
What are the best litter robot 4 waste drawer liners?
The best litter robot 4 waste drawer liners depend on the feature you value most. LotuFlor is the strongest overall choice for its strengthened bottom and 9-gallon capacity, while Elzrghs offers 100 drawstring bags and NXPPYY gives you the largest count at 160 bags.
Check the bag size and closure style before ordering.
Do Litter-Robot 4 bags need to be branded?
No. Compatible third-party bags can work with Litter-Robot 4 when their dimensions and closure fit the waste drawer.
The picks here include bags designed for Litter-Robot 4, but sizes vary from 24.4 x 15.75 inches to 25.2 x 23.6 inches.
Measure your drawer and follow the installation method for your model.
How often should you replace a Litter-Robot 4 waste drawer liner?
Replace the Litter-Robot 4 waste drawer liner when it is full, damaged or no longer seals waste well. A multi-cat home may need more frequent changes than a single-cat home, while larger bags can allow longer intervals.
Do not overfill a liner just to reduce the number of changes.
Are drawstring bags better for Litter-Robot 4?
Drawstring bags can make removal easier because you pull the closure, lift the bag and tie it before disposal. They are especially useful when you want to limit contact with waste.
A drawstring does not replace checking the bag's size, capacity and fit in the drawer.
Can Litter-Robot 4 waste drawer liners control odor?
Some Litter-Robot 4 waste drawer liners are described as helping contain odors, especially when the bag closes tightly. An unscented bag avoids adding fragrance, but the liner alone cannot replace regular waste removal and cleaning.
For related care steps, see our guide to how to clean a robot litter box.
