I've looked through all of today's Memorial Day appliance sales, these are the best by far — save up to $1,700 on refrigerators, coffee machines, air fryers, Ninja Slushi

A $50 price cut isn't the biggest in the world, but the Ninja Slushi is a popular item to say the least. It's a great little appliance that can turn juice, regular soda, and even cocktails into slushies without any extra steps - no ice needed. It's definitely a little expensive, but if you love slushies then this is a luxury that's well worth forking out for - as our review attests to.

Get the top-rated Ninja Nutri-Plus blender for $69.95 at Amazon's Memorial Day sale. The personal blender features a 900-peak-watt motor to easily whip up your favorite smoothies and comes with three 20-oz. Ninja to-go cups.

There's $50 off this smart hot-and-cold Keurig coffee maker right now. It automatically adjusts its brew temperature when you make iced coffee for a mellower flavor and to avoid diluting your drink with melted ice.

The best-selling Instant Vortex Mini Air Fryer is 46% off during Amazon's Memorial Day sale. We're particularly big fans of Vortex's Odor Erase technology (also used by the excellent Instant Vortex Plus 6-in-1), which does an excellent job at eliminating cooking smells.

Bissell portable carpet cleaners are breakout stars at holiday sales like Memorial Day, and Amazon has the top-rated Little Green Mini model for $88.97. Perfect for pet owners and parents, the portable carpet cleaner can magically erase spills and stains from carpets, couches, auto interiors, and more.

If you're looking for a powerful upright vacuum, Amazon has the best-selling Shark Navigator Lift-Away on sale for $149.99. The upright vacuum works on both carpet and hard floors, featuring lift-away technology that allows you to easily clean hard-to-reach areas by simply lifting the pod.

There's a $129 off this cordless vacuum at Amazon, matching the lowest price I've seen. It's a slightly more advanced version of the Shark PowerPro, which impressed us with its effective, affordable, no-nonsense cleaning.

The Dyson V8 Plus is plenty powerful, packing more attachments than the standard model to help you achieve the deep clean of your dreams. It can conveniently transform into a handheld vacuum and offers up to 40 minutes of run time.

There's a huge $240 off one of Dyson's best-ever vacuums right now. Unlike the standard V8, the Absolute (which is exclusive to Dyson) comes with both a Fluffy cleaning head and a Motorbar cleaning head, plus a combination tool, crevice tool, and hair screw tool.

This stick vacuum is the same as the standard V11, and is just as good on carpets, but comes with heaps of attachments for cleaning every nook and cranny — and it's the same price as the regular version in Dyson's Memorial Day sale.

There's $200 off this powerful vacuum, with a laser light and LCD display that our reviewer called "an ingenious way to measure how much you've cleaned". This model is exclusive to Dyson's own store and has a more powerful motor than the original V15 Detect.

Dyson's cheapest floor cleaner is a better value than ever with its first big discount since its launch earlier this year. This cordless wet cleaner propels itself across your floors, scrubbing away spills with its fluffy roller, and squeezing dirty water into a separate tank for easy emptying.

This self-emptying vacuum is a perfect solution for pet owners and smart-gadget lovers. At a massive 53% off the retail price and almost matching the previous record-low, you'll do well not to be tempted by the robot vacuum from Shark, guaranteed to make your life that little bit easier.

If you're looking for a wallet-friendly robot vacuum mop combo, this is one of my top recommendations – and it's even better value right now with $60 off. It's simple but effective, and the auto-empty base means you won't have to empty it by hand quite as often.
