As Assaf mentioned, most of the magic is going to be in the marketing. Certain options like influencers are really only possible if you have a great product(which you think you do).

The other important thing to remember is most products are not a "one type fits all". I personally have both a Vitamix and a SharkNinja and use them for different things(of course I wish only one was needed). And for those who only have one there is not a clear winner as people of different requirements in regards to price, capabilities, and believe it or not looks.

Direct to consumer selling is much easier today than in the past especially if you are willing to sell on Amazon. Since you have the additional products you will want to make sure you engage your customer to have high repeat buyer conversion. This is generally done through both great product but equally or more important - great service!

Also if you anticipate your product being the next big thing in the industry why not get placement in retailers like Costco where customers will expect them to be? Happy to help further strategize on all the possibilities.
