There are two different models of these blenders on sale. The Vitamix 5200 Professional Grade blender, and the Vitamix ONE. Both are great options, but you’re definitely getting a more full-featured blender with the 5200. For one, it has a self-cleaning feature that’s insanely useful. All you have to do is put in some soap and hot water, turn it on and crank it up, and in about a minute the container is clean as a whistle. It also holds more ingredients at 64oz. of room as opposed to 32oz. in the Vitamix ONE. Additionally, it has a larger range of variable speed control and is perfect for making anything from smoothies to soups, sauces, and more. For Prime Day Vitamix is discounting this model down to $299.99 from its original price of around $400. This is a pretty good savings. That being said, the Vitamix ONE doesn’t take up as much space on your countertop or in your cupboards. Plus, it’s a little less expensive with its sale price of $174.95. The Vitamix ONE also has variable speed control, it just doesn’t go as high as the 5200 model. But it still mixes and blends better than a lot of other blenders. One of the best parts about it though is that you only have one dial to mess with for blending. Which makes it dead simple to use for just about anyone. This one doesn’t have a self-cleaning feature and it’s also not safe to put in the dishwasher. So, you’ll have to handwash it. Despite that though, you’ll no doubt love this thing. Vitamix Blenders
