I ordered this litter box because of all the amazing reviews I'd read on the Luuup website. It's more pricey than my current litter box and much less convenient. Because the soiled litter would stick in the grooves and on the bottom of the box, I couldn't just sift out waste and dump as advertised. It became dirty very easily, and needed cleaning often. At which point it was like cleaning three separate litter boxes instead of one.
Another difficulty was finding privacy for my kitty, whose box was in an open area. I ultimately ordered a universal cover, which worked for a while. I eventually trashed this box when urine was consistently sprayed out of the back. I ended up with a hooded box with a door for half of the price that's much easier to clean. I hope this review helps with future improvements.
Bottom Line: No, I would not recommend this to a friend
