Product Features
How It Works
After the cat leaves the box, the globe rotates to separate the clean litter from the clumps and drops the waste into a drawer
The rake system sweeps the waste into a covered compartment 20 minutes after the cat exits
A motion sensor triggers the rake system to scoop messes into a sealed, disposable receptacle
Liquid waste is flushed away through the waste-water drain and solid waste is liquified and disposed through the drain
Cat waste is automatically raked and collected inside an easy-to-empty waste compartment
Cat waste is automatically raked and collected inside an easy-to-empty waste compartment
A quiet, slow-moving conveyor system constantly sifts the litter into a waste compartment, making one full rotation every hour
Pull the lever to sift; clean litter falls through sifter, while waste clumps are deposited into the waste bin
A motion sensor triggers the rake system to scoop messes into a disposable waste receptacle

3, 7, or 15 minutes (adjustable)

Safety
Rotation stops if cat enters, then waits 15 seconds before resuming the clean cycle; anti-pinch detection stops the cycle and reverses for 2 seconds
If a cat enters during cleaning, the rake will stop and the timer will reset itself for 5, 10, or 20 minutes after the cat leaves
The rake has a safety bar that will stop and reverse if it touches any object that has gotten behind the rake during a cleaning cycle
The cleaning cycle is delayed for 10 minutes if a cat enters the bowl during the cycle
The motor unit will stop if it encounters excessive resistance
The motor unit will stop if it encounters excessive resistance
Designed to have no visible exposed moving parts, the Litter Bowl rotates at a safe rate of one rotation per hour
Completely manual
During use, the safety bar behind the rake will stop and reverse the raking action in case your cat jumps behind the rake during the cleaning cycle
Frequency of Waste Disposal & Cleaning
Empty drawer every 7-10 days for one cat Deep clean twice per year
Replace litter tray every 20-30 days for one cat Clean a few times per year
Waste receptacle and carbon filter must be replaced every 3-7 days; weekly and monthly cleaning necessary
Self-washing; should be cleaned a few times a year
For a single-cat household, change the bag about once a week and the filter once a month
In a one-cat household, the litter should be emptied and the box cleaned and re-filled with fresh litter about once a month
Remove the waste bag when nearly full or every other day to control odor build-up and bacterial growth
Remove the waste bag when nearly full (typically 1-2 weeks) Clean a few times per year
Remove the waste bag when nearly full; requires weekly cleaning of ramp and motion sensors and more thorough monthly cleaning
