I recieved The ScoopFree Self-Cleaning Litter Box, Second Generation for free in exchange for a fair and honest review. I had a different self cleaning box and I will say this one is 10x better. Easy to set up and change litter tray. It is alot quieter when it rakes the crystals. My floors are alot cleaner around the area but the best part is I didnt have bad odors and I didnt need to touch it for 3 weeks to change it. It cleans about 15 min after kitty leaves the boxI really like the lavender scent and the have original which was nice to. Perfect for when your away on vacation.
