Key Features Breakdown

Cat Litter Box Benefits and Features

Understanding smart litter box model differences is crucial while choosing one. Each choice improves ease, hygiene, and monitoring with distinct features. There are cat litter boxes for budget-friendly self-cleaning and complex systems with remote monitoring. Below, we compare the top features of four popular models: PURA MAX, MAX 2, MAX PRO, and PUROBOT ULTRA to help you choose the best one for you and your feline companion.

Camera & Monitoring Capabilities

For most pet owners, monitoring their pet's activities and health is important. This is where cameras and monitors help. Some smart litter boxes use cameras to track your cat in real time, while others are simpler. Let's examine each model's surveillance capabilities. MAX PRO and PUROBOT ULTRA offer advanced monitoring right at your fingertips, so if you care about your cat's habit, pay attention.

Pet owners may remotely manage cleaning schedules and waste levels with smart litter boxes.

MAX PRO allows real-time video streaming of your cat's behaviour away from home. PUROBOT ULTRA extends voice control to hands-free operation. Smart litter boxes come with basic remote control or advanced AI integration.

Waste Collection & Bagging System

Smart cat litter boxes manage waste effectively, which is a huge benefit. All types automate scooping; however, trash collection and disposal vary. Some are hands-free, while others require manual interaction. An advanced waste bagging system can make all the difference for minimal effort. Waste disposal models range from manual bagging to fully automatic.

Requires manual bagging after collecting waste

MAX PRO

Uses a pull-out waste bag system for easier disposal.

Capacity & Size

Storage capacity is important when choosing a smart litter box, especially for multi-cat families or pet owners who clean less often. The garbage bin size dictates how often you must empty it, while the inner drum capacity decides how much litter it can hold. A higher capacity can make maintenance easier if you want to manage more garbage between cleanings. To help you choose, we compare model storage sizes below.

Mobility & Portability

If you regularly move your litter box for cleaning, rearrangement, or travel, portability is important. Some types have handles and wheels for carrying, whereas others require disassembly. A model that's easy to move can save time and effort if convenience and flexibility are important. See how each smart litter box handles mobility.

Odour Control

No one enjoys a smelly litter box, thus odour control features are important. Some machines contain waste bin odours, while others deodorise the entire home. Choose a litter box with superior filtration and deodorising technology to reduce odours. Let's see how each model handles odours.

PURA MAX & PURA MAX 2

Odor control mainly in the waste collection bin (with optional smart deodorizer).

Full coverage odor control for both waste and drum.

Suitable Cat Litter Types

The right cat litter is as essential as the right cat litter box. Some cats have litter sensitivities or prefer a certain texture. Luckily, all four models—PURA MAX, MAX 2, MAX PRO, and PUROBOT ULTRA—support several litter types, so you may choose what works best for your cat.

These smart litter boxes are compatible with:

  • Tofu litter – A natural, biodegradable option that clumps well and produces minimal dust.

  • Bentonite litter – A popular clay-based litter known for its strong clumping ability and excellent odor control.

  • Mixed litter – A combination of different materials, offering balanced absorption, clumping, and odor management.

These smart kitty litter boxes let you choose between eco-friendly tofu litter and exceptional bentonite absorption. The key is choosing a litter that is comfortable for your cat and works well with the automatic cleaning mechanism.
