Our cats were always very stinky with traditional litter boxes
As a compromise solution I've had pretty good luck placing air filters next to the litter box. The commonly recommended ones (Coway, Winix) are $100-$150 on sale and have both particulate filters and charcoal odor filters. Filter costs are ~$25/year and electricity cost is ~$5-10 per month.
That's probably more expensive over a large enough number of years relative to a robo litter box, but you're also removing other indoor allergy causes as well, so it's doing other work which may be beneficial.
Also the fan noise from the filters is very gentle; actually a plus for many.
