Description
Product Overview
The Litter-Robot 4 Supply Bundle by Whisker is engineered to transform the routine of cat litter management into a seamless, automated experience. At its core, the Litter-Robot 4 features a patented sifting mechanism that rotates after each use, separating solid waste from clean granules. This self‑cleaning action occurs within seconds, depositing waste into a sealed drawer that can be emptied without ever touching the litter itself. The unit is constructed from high‑impact, BPA‑free polymer that resists scratches and odors, ensuring durability for years of daily use.
Included in the bundle are three OdorTrap refills, each designed with activated carbon and a proprietary scent‑neutralizing matrix that captures ammonia and other volatile compounds. Ten waste drawer liners provide a hygienic barrier that simplifies waste removal, while thirty pre‑moistened cleaner wipes make quick surface sanitation effortless. Two additional carbon filters extend the odor‑control performance, and the entire system is powered by a quiet 120‑V AC motor that operates below 55 dB, making it suitable for any home environment.
The dimensions of the unit—27 × 24.25 × 29.5 inches—and its 24‑pound weight strike a balance between stability and portability. Designed for up to four cats, each feline must weigh at least 3 lb (1.4 kg) to trigger the weight‑sensing scale that activates the cleaning cycle. The built‑in scale also records each cat’s weight, allowing owners to monitor health trends over time via the Whisker mobile app. The app provides real‑time alerts for waste drawer fullness, litter level, and filter replacement, ensuring the system remains optimally functional.
Usage
Designed for modern households, the Litter‑Robot 4 fits seamlessly into a variety of living spaces—from compact apartments to spacious family homes. Place the unit on a firm, level surface; carpeted floors are acceptable if the unit is stabilized with a non‑slip mat. The automatic cleaning cycle begins after the cat exits the box, typically within 30 seconds, and the waste drawer locks securely until the owner removes it. This hands‑free operation eliminates the need for daily scooping, reducing exposure to dust and allergens.
Because the system monitors litter levels, owners receive notifications when the granules run low, prompting a quick refill. The included OdorTrap refills last approximately three weeks under normal usage, but high‑traffic homes may replace them more frequently. The carbon filters should be swapped out every two months to maintain peak odor‑control efficiency. The unit’s quiet motor ensures that nighttime use does not disturb sleeping family members or other pets.
Ideal for multi‑cat families, the Litter‑Robot 4 can accommodate up to four cats simultaneously, provided each meets the minimum weight requirement. The weight‑sensing technology distinguishes individual cats, allowing the app to track each pet’s weight and litter habits separately. This data can be invaluable for early detection of health issues such as weight loss or urinary problems.
