I test home appliances for a living: These are the Ninja, Shark and De’Longhi deals I’d snap up in the Amazon Big Spring Sale

If you're looking for a powerful and versatile upright vacuum to deep clean your home, the Shark Stratos is worth the investment, and with a 43% saving, it’s an excellent buy. What's more, we gave it 4.5 stars in our review. Our reviewer says, "Not only does it boast powerful suction that can handle any debris, but it’s packed with useful features, from a tangle-resistant brushroll to a built-in scent cartridge, that make it easy to use."

This vacuum is 30% lighter than other Shark vacuums and performs well on both carpets and hard flooring. When testing, we loved the multi-surface cleaning features and its self-cleaning brush. But what particularly makes it stand out is that when it’s returned to the charging dock, it auto empties into the base.

Ninja's NeverClog Cold Press Juicer removes the hassle of juicing fruits and vegetables. The special filter pushes pulp through without clogging and lets you customize the amount of pulp in your juice with two interchangeable pulp filters. It comes with a 24-oz juice jug and a 36-oz pulp container, allowing you to make large batches of juice, rather than single servings.

This stylish Ninja coffee maker comes in a gorgeous choice of colorways, including Sage Green, and is now on sale for $30 off. Whether you prefer pods or grounds, this device makes tasty brews in 7 sizes (6-oz. to 24-oz) and has a built-in, fold-away milk frother! The only problem you'll have is deciding which color to choose.

With a 4.5-star rating, our reviewer loved this luxurious espresso machine. She said, "It’s one of the most versatile and robust espresso machines I’ve ever used," and "It can make black Americanos to cortados, to cold brew, to iced lattes with ease." She also found the built-in conical burr grinder reliable and consistent, and the steam wand perfect for steaming microfoam. It's a premium price, but with a 28% discount, we think it’s worth considering.

The De’Longhi Dedica Duo is a dual-brew espresso machine that measures just 5.9 inches wide, so it won’t take up too much room on your countertop, making it perfect for smaller living quarters. There are three preset recipes, a professional pump, a digital touch display, and a commercial-style steam wand. It's so easy to use that anyone can make a perfect coffee with it.
