This smiley face-shaped sponge is no ordinary cleaning product; especially considering it’s earned over $200 million dollars in sales. So what sets it apart? For one, it has special FlexTexture foam that keeps it from scratching even the most delicate surfaces like glass and leather. It can be used as either a firm sponge for tougher scrubbing when you place it in cold water, or a softer sponge for more gentle jobs when you rinse it in warm water. Reviewers say it’s great for cleaning everything from cast iron skillets to car exteriors with ease. “This is the only kind of sponge I buy now,” declares one customer.

The most comfortable hoodie you’ll ever own is aptly named the Comfy. It’s an oversized sweatshirt/blanket hybrid that's designed to keep you warm and cozy thanks to its plush sherpa lining.

And the over $150 million in sales so far prove we’re not alone in thinking so.

When Wes LaPorte and Dan Barnes invented PhoneSoap, a UV sanitizing device for your phone, in 2010 they were determined to help eliminate the buildup of germs, bacteria and even fecal matter that often lives on cell phones. With Lori Greiner’s investment, the company’s sales soared to $46 million in 2019. And with the emergence of coronavirus, PhoneSoap only gotten more popular; it was sold out for the majority of the spring.

Home cooks, this one’s for you. The Frywall is BPA-free silicone splatter guard that ensures oil doesn’t jump out of the pan and burn you or create a mess.

This is the best thing since sliced bread,” writes one buyer. Just note that this particular Frywall is only compatible with 10-inch wide pans.

No sharks bit on this product (get it?), but we think it’s pretty smart. Evidently, so do over 1,500 buyers, who gave it five stars on Amazon. The silicone sprayer and scrubber in one can be attached to either your shower or hose when it’s time to wash your pup. It even has a special low setting for washing sensitive areas like the face and belly. We’re also fans of the brand’s other design, the Slow Treater. It’s a mat you cover in peanut butter and attach to the bathroom wall to keep your pet busy and distracted during bath time.

Here’s another product that ultimately didn’t secure an investment from the sharks, but has gone on to be quite popular. Like, 1,7000 five-star reviews on Amazon level popular.

This convertible bean bag chair has raked in over $48 million in sales. Not too shabby. In its original form (which is a bean bag), it serves as comfy extra seating in the living room.

The sharks were so impressed with this transitional sippy cup that two of them decided to invest. The Lollaland Lollacup is designed to help babies transition away from using a bottle and adjust to drinking through a straw. But unlike most sippy cups, this one is purposely not spill-proof so it teaches kids the reality (and potential danger) that comes with drinking from a cup. It serves as the perfect training cup.

We love a good multiuse product, so we’re definitely going to invest in a few Safe Grabs mats for our kitchen. The food grade silicone mats can be used as a potholder, microwave splatter guard, utensil rest, placemat and more. “I leave my big one in the microwave as suggested so it’s always ready to use with hot dishes.
