Modkat Flip Litter Box

We have 7 rescue cats, one of whom sprays urine over the box interiors. She would hit the tops of our litter box covers and spray through the connections between the box and the cover - hitting drywall and floors.
The Flip litter box is the best thing out there for a cat like her. She can spray high, but not that high. She was found starving in an HVAC warehouse with broken back legs from a car accident. I always wonder if her litter box spraying was a factor in her homelessness.
I've swapped 3 litter boxes for the Modcat and have a 4th ready to use. I'm only using the top on one (open halfway) because the other two are under furniture. I don't ever use liners. They would be caked with urine immediately. Instead, when I clean the litter, I take a few very damp paper towels (Dawn + a little Clorox) and wipe the sides of the box down. Perfect clean litter box every time.
The box is not perfect, perfect. The corners are a little tough even with their rounded plastic molding. I keep some Q tips near the litter box for those. I've used dozens of litter boxes over many decades and this is one of the very best.

The box is very well made and the idea of the liners sounds great although how do I clean the liners? If I wipe them down, they still smell. I am curious how people use them for 3 months. After one use I want to throw it out because it smells. I tried putting it in the washing machine, but that didn't seem like a good solution either since I can't put in the dryer. If you could let me know how to deal with the liner I would appreciate it.
Also, it doesn't make sense to me to have the scoop hanging outside the box with nothing for it to sit inside of. If I am using that scoop it looks rather unsightly and drops cat litter on the floor. If you have a solution to that I would be interested.

Well made and the cats are cool with it.

I was gifted the XL catbox years ago and loved it. I needed to replace another old box, and thought this one would be adequate for my space. However, a couple of my cats are bigger, and have already gone outside a few times because they don't fit. This is great if you got smaller cats (like 9lbs or less). Probably gonna splurge on another XL since that suits my cats' needs better.

I’m very happy with the litter box. Very well designed and well made. We found the liner not really necessary but it’s a good option if someone wants that. Our cat is a vertical pee’er so she would pee right over the side of a regular litter box. We tried a litter box with a cover, bottom 1/2 and top 1/2 but the pee would seep through the crack where the two halves joined.
This box keeps all the pee inside. It’s easy to clean and nice looking.
The only negative is the price, it’s a bit expensive but the product is great.
