BRILLIANT PAD - World First Self-Cleaning puppy pad & dog potty. This could be perfect for seniors with dogs who are paper-trained, or anyone who can't get out of the house on a terrible winter day. Designed to handle #1 and #2, the highly absorbent BrilliantPad soaks up liquids and dries out solids. It wraps and seals waste to keep your home clean and odor free. A built-in timer replaces the pad automatically or you can refresh anytime at the touch of a button. A sensor won't let the machine start until the pad is clear of your pet. Waste is sealed inside while outside remains dry and your hands stay clean. Biodegradable caps prevent leaks and foul odors. One long-lasting roll lets you enjoy your pet without the clean-up chore. The company says one roll = 27 regular wee pads. The company says it's perfect for small dogs up to 25 pounds who already use pads or for puppies you're going to train to use pads. Medium dogs 25 to 40 pounds might use it, but it's not for dogs over 40 pounds. It was $149.99, but as of 11/24/18, it was $99.99 on Amazon. Refills are $20 to $32 depending on the number you buy and if you subscribe to one of their refill plans.
