Adaptive Self-Cleaning Algorithm. The HKM-392147 employs a weight-sensitive platform combined with infrared motion detection. After your cat exits, a countdown initiates — typically 90 seconds — ensuring complete safety before the automatic sifting cycle begins. Waste is separated into a sealed lower compartment, reducing odor leakage by up to 85% compared to open trays.

Whisper-Quiet Operation. The brushless motor operates at less than 45 dB during cleaning, quieter than a household conversation. This low-noise design helps timid or anxious cats adapt faster. The round drum rotates smoothly on precision bearings, eliminating sudden jerks that might startle your pet.

Multi-Cat & Large Breed Ready. With a usable interior floor area of approximately 460 in² (0.30 m²), even Maine Coons or Ragdolls weighing up to 22 lb find comfortable positioning. The weight sensor automatically distinguishes between different cats (when weights differ by >1.1 lb / 0.5 kg), logging individual usage in the companion app.

App Ecosystem & Smart Home Integration. Connect via 2.4G or 5G WiFi networks. The HKM Home app (iOS & Android) displays real-time litter box status, 7-day usage history, and waste drawer fullness. Push notifications alert you when the waste container reaches 80% capacity. Compatible with voice assistants for basic status checks.

Designed Around Feline Behavior

The distinctive round architecture isn't just aesthetic — it mimics the enclosed dens cats instinctively seek. The entryway sits at a comfortable 7.9 in (20 cm) height, easy for seniors or kittens above 3.3 lb. Inside, the texture of the PP surface provides secure footing without abrasive ridges that might deter sensitive paws. The carbon-infused filter module snaps magnetically into the rear ventilation port, replaceable every 30 days for peak performance.

Easy Deep Cleaning. The entire globe separates from the base with a quarter-turn release. All plastic components are rinseable with mild soap and water. The waste drawer includes a smooth, non-stick coating that resists clumping litter adhesion, reducing scraping during monthly deep cleans.

Frequently Asked Questions
What litter types are recommended? +
Clumping clay or silica gel litter works best. The sifting grate is optimized for particles between 0.08–0.2 in (2–5 mm). Avoid non-clumping, pine, or crystal litters with oversized granules, as they may not sift efficiently.
How often must the waste drawer be emptied? +
For one average-sized cat, approximately every 5–7 days. The app provides percentage-based alerts. Drawer capacity is 3.3 gal (12.5 L), accommodating multiple days of waste for multi-cat households.
Is it safe for kittens under 3.3 lb? +
The weight sensor requires a minimum of 3.3 lb (1.5 kg) to reliably detect presence. For kittens below this threshold, we recommend manual mode until they reach the safe weight.
Does it work during a WiFi outage? +
Yes. The onboard button panel retains full cleaning functionality offline. Scheduled cycles stored in local memory continue to run. App features resume automatically when connectivity is restored.

keyboard and case is phenomenal, trackpad is borderline unfunctional
Color: Black
I bought this case, because of the keyboard and trackpad, i wanted to use my ipad more like a laptop. the keyboard is phenomenal and certaintly better than other cheap ipad keyboards i have tried, I can actually use this one without having to repeatedly slam or hard press certain keys and can actually have a flow of typing. additionally, everything else regarding the case itself is amazing. it isnt cumbersome or bulky and it is very easy to swap between ipad and laptop mode on the fly. the trackpad however is genuinely unusable. the sensitivity on the trackpad is horrid and I cannot figure out how to change it, and additionally, clicking using the trackpad is outright impossible. you try to left click, it registers as a right click, or you try to click and it instead snaps your cursor to the bottom of the screen instead. it is also impossible to use any gesture functions with the trackpad, even something as simple as scrolling up and down or left to right is impossible. it is outright impossible to have any kind of workflow using the trackpad. it is unfortunately just a lot easier to use the keyboard and touch screen! its a shame that the keyboard and case itself is very nice too, so I will now have to spend more money on a separate mouse, which is additionally ANOTHER item i will have to carry around, just to make what I already bought work the way I expected.
