No more cat litter dust, smell or clumps! My cat has asthma and eliminating dust is a must. I clean regularly for normal settling dust on furniture but the crazy amounts of cat litter dust flying around in my air unit is no longer a problem in my house!! I have the catgenie set on cat activation mode, it cleans itself after each time cats use the bathroom...day or night. I no longer clean, take trips to the trash can with big smelly cat waste garbage bags, have a supply of litter laying around the house or have a dusty breathing environment. It makes life so easy that having cats feels like having dogs that I don't need to walk!
