We are over the moon in love with this product. It's super quiet and very low maintenance. And the features are amazing. Simply hook it to your wifi and Bluetooth and it will show you your pets health when they finish using it. One of the greatest features is the rake timer. You can pick how long before the rake starts cleaning up your cats business. And if it's in the middle of cleaning and your cat gets back in it the rake will automatically stop and the timer will reset. I highly recommend this for anyone with cats
