Both the M2 and M4 are fully automatic self-cleaning litter boxes, but they are designed for different needs and preferences.

1. Size & Capacity

• M2: Standard size, suitable for most homes and 1–2 cats
  
• M4: Larger capacity, better suited for bigger cats or multi-cat households
  

2. Control & Operation

• M2: Offers more advanced controls with multiple button functions (clean, empty, reset, mode switching) for users who prefer flexibility
  (see details on page 8 of the M2 Instruction Manual)
  
• M4: Features a simplified control panel with fewer buttons, designed for a more intuitive and easy-to-use experience
  (see details on page 11 of the M4 Instruction Manual)
  

3. User Experience

• M2: Better for users who want more control and customization
  
• M4: Ideal for users who prefer a simple, plug-and-play experience with minimal setup
  

In short:

• M2 = more control
  
• M4 = easier to use
  

Both models are larger than traditional litter boxes due to their fully automatic design, which enables hands-free cleaning and improved hygiene.

M2 litter box can significantly reduce and control odors. With its scented deodorizing sheets and sealed waste drawer at the bottom, it effectively reduces odor leakage. Although it can effectively reduce unpleasant odors from the litter box, achieving complete deodorization may be affected by various factors, including the type of cat litter used, the frequency of waste disposal, and the home environment

M2 automatic litter box does not require special cat litter and is compatible with most clumping cat litters. These litters should have strong clumping ability, high absorbency, and low dust characteristics. Recommended litter types include mineral/clay clumping litter, mixed litter, etc. Please note that non-clumping crystal litter is not compatible

Many cats adapt well to the M2 litter box, thanks to its quiet operation, low-entry design, and safety protection system. We recommend placing the M2 litter box in an area where your cat is familiar with its surroundings and keeping the old litter box nearby during the transition period. Most cats will accept the M2 litter box within 1-2 weeks, especially if you gradually mix the old litter into the M2. For hesitant cats, temporarily disabling the automatic cleaning function can help boost their confidence

When the cat enters, the litter box drum immediately stops rotating. The M2 litter box is equipped with multiple safety protection mechanisms: a weight sensor pauses the cleaning function when it detects that the internal weight exceeds 2.2 pounds, and an infrared motion sensor immediately stops rotation when it detects any movement.
