7 Best Bags for Litter-Robot

The Litter-Robot is one of the best automatic cat litter boxes with raving reviews because it’s easy to use and is great at controlling foul smells and reducing tracking. 

But you need suitable waste bags, or your cat waste will get all over the drawer during the cleaning cycle. 

So, which are the best bags for Litter-Robot? The best bags are large enough to fit inside the waste drawer of your self-cleaning litter box and thick enough not to break apart when you remove them. 

Let’s take a look at my favorites.

1. The Strongest and Best Fit: Whisker Litter Box Liner Bags

Whisker is the official manufacturer of Litter-Robot, so they offer the best bags for Litter-Robot, custom-fit to match the drawer.

The brand’s waste drawer liners are the best option compared to alternatives as they are designed to fit the Litter-Robot perfectly.

They are also thicker than most other options, which means there is less risk of the bags ripping.

A great quality to have, as the last thing you want is for the bag to tear as your carry it through your house to dispose of it!


  • The bags are compatible with all Litter-Robot self-cleaning litter boxes, so you don’t have to look for alternatives if you have an older and discontinued unit.
  • Made from durable plastic with 9-11 gallons of usable capacity, so you won’t have to replace the poop drawer liners very often.
  • Relatively good at containing the bad smell inside the waste drawer

  • No drawstrings for closure 


They are my top pick because they are the strongest, and easiest to fit as they are a perfect size.

While expensive, these best Litter-Robot bags are heavy-duty and unlikely to tear when cleaning the waste drawer. As such, if you have a single cat, they’re worth the extra bucks. 

Changing the bag doesn’t take you more than a minute or two. 

One great feature of the brand bags is pointed out by happy cat mom, Karen, who says this – “The liners hold my urine, so I haven’t had to worry about the liners leaking like another company I bought liners from.”

4 Litter-Robot Bag Alternatives

cat litter robot 4

Not all cat owners are fans of plastic or biodegradable bags. Fortunately, I still got four Litter-Robot bag alternatives to help you keep your waste drawer as clean as possible. 

1. Disposable Aluminium Trays

Litter-Robot’s waste drawer measures 11″ x 16″ x 6,” so you can find plenty of disposable aluminum trays that fit inside.

Disposable trays are cheap, and you can find them easily online or in the nearest supermarket. The drawback is that some trays don’t sit completely flat inside the drawer, so it gets messy.

Make sure the foil is molded a little bit, so it fits the shape of the waste drawer snugly. Otherwise, the tray can trigger the weight sensor.

2. Large Plastic Bags

Cat parents probably have tons of old plastic bags around the house, so you can use the largest ones to line the waste drawer, as long as they don’t have any holes.

Unfortunately, while cheap, plastic bags rip easily, so you can make a huge mess inside the house if you aren’t careful. And it’s not a very eco-friendly solution. 

3. Plastic Pans

If you’re not opposed to scooping and cleaning a plastic pan, you can use one inside the waste drawer.

It just should be shallow enough not to trigger the weight sensor.

4. Stainless Steel Lasagna/Cake Pan

A stainless steel pan is another Litter-Robot bag alternative. There are plenty of stainless steel pans that are a good fit for the drawer, so you can use them over and over again.

The main con is washing and scooping these pans to keep odors from accumulating, making it no different from a regular litter box. 

Why Use Bags for Litter-Robot

litter robot bags

Automatic cat litter boxes are great for people with disabilities or those that work long days, especially if they have a cat that prefers a fresh box for every use.

Using a liner bag in your Litter-Robot makes life even easier. But you need suitable waste bags, or your cat waste will get all over the drawer during the cleaning cycle. 


What size bag does the Litter-Robot use?

The Litter-Robot can use kitchen trash bags with 10-13 gallons of capacity. They’re large enough to fit inside the waste drawer with enough usual capacity left. 

How Do You Use Bags in Litter-Robot?

To use bags in a Litter-Robot, roll the edges of the bag a couple of times and place them at the appropriate tabs at the back of the drawer. Stretch the bag tight and hook the other end to the front tabs. 

How Many Litter-Robot Bags Do You Need Per Month? 

In general, cat parents will need around 4-5 bags per month for a single cat.  You should empty the waste drawer every week or whenever the full sensor activates and put in fresh litter.


Litter Robot does all the hard work of scooping and removing your cat’s waste and containing dirty litter. All you have to do is to pick the right bags to reduce the mess inside the waste drawer and contain odors.

The best bags for Litter-Robot are those that come from the manufacturer because they’re the right size and are thick and heavy-duty to prevent odor leakage and spillage.
