Instead of clumping or clay litter, use pine pellet bedding for horses. It's effective, inexpensive, has no unnatural chemicals, smells great, and lasts about twice as long as other litters. If you use pine pellet litter, you can tell by looking at it when you need to wash and refill the box. As it absorbs urine, the pellets turn into sawdust. When there are no more pellets, it's time to dump the box and start fresh.
The same product is packaged for cats, as "Feline Pine," for about 3 times the price. Some pellet stove fuel is also okay to use for cat litter. If the label doesn't say it's okay for animal bedding, it can be toxic.
Use hot soapy water and a toilet brush to scrub out the litter box. You can also put some borax or washing soda in the bucket. Rinse and dry thoroughly before refilling. Letting it air dry in the sun can help with odors. NEVER use chlorine bleach to clean a litterbox. Urine turns into ammonia, and mixing chlorine and ammonia results in toxic chlorine gas, not good for you or kitty. Don't try to deodorize it with citrus oil cleaners or vinegar. Both citrus and vinegar are effective cat-repellants.

With this system you use clumping litter and every other day lift out the layer on top and it sifts the good litter down for the next day. Then just throw away the layer with the soiled litter.
After keeping cats for years and having a smelly house, this seems to work best. For me, the convenience and the peace of mind of not having a stinky house makes this system worth while. Hope this helps. Blessings.

The ScoopFree automatic litter box system is a combination of an automated rake device which fits over a pre-packaged cardboard litter box filled with liquid absorbing crystals. The starter system cost me about $110 at Petco including the automatic rake and the tray refill. Each additional tray refill costs about $15 and, with one cat, is supposed to last up to a month.
Unfortunately for me, the ScoopFree has been a disaster. Setup was easy and the cat took to the litter box fine, but the first tray refill didn't last anywhere close to a month. After only about a week, the tray was already saturated with urine.
The system has an automatic rake which activates periodically. It first rakes forward pulling any solid material into a catch at the far end of the litter box. Then it rakes back re-distributing the crystals throughout the box and presenting a clean litter surface for the cat's next visit.
At least that's the theory. In practice, the crystals in my box clumped together so the middle of the box ended up nearly devoid of litter. Litter is pushed into the catch for solid waste end, but even worse litter ends up crushed in the area behind where the rake parks.
I can use a litter scoop to redistribute the crystals every day which helps some. Even so, after only about a week, the whole system is so saturated with urine that the tray refill has to be changed.
The cardboard tray refill is coated so the urine isn't supposed to seep through. The idea is that the lid can simply be put on the box and the box put in a garbage bag for disposal. Again in theory. Unfortunately, that only seems to work when the litter is distributed properly. One tray refill I changed was so damp that the cardboard had lost its structure. I had to slide a garbage bag under the tray because lifting it would have been impossible.
It's almost hard for me to overestimate how disgusting the device becomes when the litter is saturated.
