Because it's such a strong hands-off solution, the Litter-Robot and its hefty price tag are worth it for people who want to spend less time cleaning the litter box and are willing to pay for it. This investment could save you hundreds of hours.

"The design of the dome with its rubber liner makes its automatic emptying process almost infallible." A Litter-Robot is ideal for a household with multiple cats, like Redmile's. Two cats fill up one regular litter box quickly, so having one of these auto-cleaning devices saves you from daily drudgery.

I've had two Litter Robots. One of them was refurbished and lasted 3 years with no issues. The other is going on 5 years with no issues - I haven't had to spend any money on parts replacements. As far as cleaning, it takes me 30 minutes each month to fully clean the globe.

Erica Shaffer is an American actress who has worked in independent films and television. Her film appearances include A Family Affair, The Truth is Always Complicated, The Fall, Catalina Trust, The Socratic Method, Three on a Match and West Coast.

The Litter-Robot is designed to be compatible with any clumping litter and it doesn't require custom, chemical-laden products. Natural clumping litter will break down into organic components. This reduces environmental impact and landfill waste.

Litter-Robot's patented sifting system is more efficient and saves money by using up to 50% less litter. That means more pocket money to spend on your furry family members! With Litter-Robot, you'll know those paws encounter a clean bed of litter every time. No more dirty paws around the house.

The best robot litter boxes that clean up after your cat (so you don't have to)

• Whisker Litter-Robot 4. Best robot litter box overall.
• Catgenie AI Automatic Cat Box. Best litterless robot litter box.
• Smarty Pear Leo's Loo Too.
• Whisker Litter-Robot 3.
• Littermaid Multi-Cat Self-Cleaning Litter Box.

We recommend up to 4 indoor cats per single Litter-Robot; however, we do have customers with more cats using a single unit. As a rule of thumb, one cat using Litter-Robot 3 requires that the drawer be emptied once per week; two cats, twice per week; three cats, every other day, and so on.

With the Litter-Robot's patented sifting technology, only the clumps are removed. This ensures that your litter box is clean, but it also saves money on cat litter. You aren't throwing away mounds of clean litter. Instead, pet parents have reported savings of up to 50% on their litter consumption annually.

For optimal odor control, we recommend changing the filter every three months. If you use scented litter, change the filter more frequently, as it will also absorb the fragrance. Replacement Carbon Filters can be ordered at www.litter-robot.com.
