Hate lugging a heavy vacuum up and down your stairs? You won't have to with this cordless vac — the sleek design is a major upgrade from bulky dirt-busters of yore. It transforms into a handheld for cleaning furniture and higher surfaces, and a filtration system traps allergens such as pet dander. Score this household helper (one of Yahoo editors' picks for this year's best vacuums) for just $320 — a cool $100 off.

"I was unsure about spending so much money on a vacuum but oh my gosh. My house is clean!" said one pet parent. "I used to have to vacuum and use this rake/broom thing to remove dog hair. Not anymore! I appreciate that it picks up all the dog hair and I don't have to worry about the hair getting tangled on the vacuum head. Never did I think a vacuum would make me this happy!"

More than 110,000 Amazon shoppers give them a five-star rating and attest to their softness. "I love these sheets. They feel so expensive and luxurious," said one reviewer. "They have almost a silky-soft feel to them and I love that they're cool every time you get into bed."

If you're not an AirPods person but want to give earbuds a try, go with this more affordable waterproof pair with over 180,000 five-star reviews. They offer superior audio quality, courtesy of 6-millimeter speaker drivers that produce powerful, crystal clear sound and heart-thumping bass. They also have a wireless charging case and can last 30 hours: six hours from the earbuds themselves and an impressive 24 hours from the case.

"These headphones are literally fantastic. I am a professional musician, and these have an incredibly clear sound quality and really high-end parts," shared a satisfied Amazon shopper. "The connection is fast and easy, it charges while in the case, which is a great feature ... Really high-end headphones for an amazingly good price."

Nab one of Lululemon's popular belt bags from its "We Made Too Much" section while it's just $29. The water-repellent 1-liter bag makes it easy to keep your essentials close, whether you're running errands or running laps in the park. The strap is adjustable, so you can find the perfect fit to wear it around your waist or across your torso. 

"The 1L size is just right — it's compact, yet spacious enough to hold all my essentials," said one shopper in the reviews. "I can easily fit my phone, wallet, keys, and a few small personal items without any hassle. The hands-free design makes it incredibly convenient for running errands, going for walks or traveling."

You can feel the difference when you're using an electric toothbrush versus a regular one. We've dubbed this one the "Ferrari of toothbrushes." Thanks to its four brush modes, you can set it for sensitivity, deep cleaning, gum massage and even whitening. It has a built-in 30-second timer and a two-minute auto shutoff to help you develop a better brushing routine. You get eight brush heads — each one should last you about three months, so eight should last you just over two years! No more shelling out piles of cash for replacement heads.

"My teeth have never felt so clean! I have used an electric toothbrush my whole life, and this is by far the best!" wrote one convert. "I usually buy Philips Sonicare, but I wanted something a little less expensive. I was nervous at first, but the quality of this product is incredible! Very powerful motor and plenty of replacement heads. The matte black finish looks very sleek and modern."

This straightening brush may just turn a bad hair day into a good one. Its ionic generator helps smooth out hair and adds shine, while its brush detangles and straightens. Choose from six heat settings and temperatures ranging from 270°F to 450°F, ideal for customizing your styling to your hair type. The built-in LED screen shows exactly what temperature you're working with at any given moment, and there's no worries about leaving the house with your brush still on — this smart cookie has a 60-minute auto-shut-off feature. 

"Wow! Straight hair without the damage," marveled one reviewer. "This brush is amazing. One pass and my bedhead hair is smooth and sleek. Especially love that it doesn't damage my hair like my flat iron and I can use it on a low temp and still get great results."

If you have trees in your yard, they probably need a bit of pruning. Compared with a pair of traditional pruning shears, this little battery-operated chain saw makes the job practically effortless. It's only 4 inches long, and there's a safety lock that has to be pressed before the saw activates. Plus, it comes with a handy carrying case, so you can safely store the device when it's not in use. 

"I'm so glad I didn't spend a bunch of money buying a lot bigger electric saw," one reviewer said. "All I really need to do is cut small branches and saplings. This little guy did it with ease. I was really surprised at the power, to be honest with you. ... It cuts through small saplings like a hot knife through butter. I would most definitely recommend this for small jobs."

If you're looking for a classic Keurig brewer, this one is nearly half off. It makes 6-, 8- and 10-ounce cups. It also has a 48-ounce water reservoir, so you don’t have to fill it up between each brew. Plus, it's always ready — it can turn on and brew a cup in less than a minute.

"I simply love it!" said one Amazon shopper. "I also noticed that this brand is very simple to use and can make coffees for an entire family. We use it at work so I was like, 'If this can take on my entire department, plus me an avid coffee drinker, then it can be good for my wife and I.' So I purchased and it works great so far!"

Dirty carpets? This Hoover offers a robust set of SpinScrub brushes and a nozzle that uses powerful suction to lift stains. It even applies hot air to the just-cleaned carpet as it rolls on, ensuring a quick dry time and letting you, your family and your fluffy friends enjoy your pristine floors ASAP. It comes with an 8-foot hose for hard-to-reach areas, a stair tool, an upholstery tool, a crevice tool and a sample bottle of carpet cleaning solution.

"Amazing results" said one Walmart shopper. "I mistakenly bought a white rug not knowing how quickly it would get dingy and dirty. I also have a dog that tracks dirt inside. This carpet cleaner made all my rugs and carpets look and smell brand new again. The dirty water and debris that it pulled up from my carpets was disgusting, but so satisfying that it's now clean and sanitized."

Summer is grilling season, but if you don't have the space for an outdoor appliance, check out the Ninja Foodi Smart XL Pro. It's marked down to its lowest price ever on Amazon. It has seven different cooking functions: grilling (obviously), air frying, broiling, baking, roasting, dehydrating and griddling. There are also four no-brainer smart protein settings: Just insert the Foodi Smart Thermometer (it’s included) and choose between nine customizable doneness levels. 

One of Yahoo's shopping writers put this on her summer wishlist, and over 1,300 Amazon shoppers have given it a five-star rating.

"We bought this grill as a way to decrease use of oil and pan frying," explained one Amazon reviewer. "The smart temperature cooking mode is probably my favorite feature. It cooks all kinds of meats, but I've only cooked chicken and steak. The meat comes out perfectly cooked to temperature [and] retains moisture and flavor, with very little mess. The device is also super easy to clean!"
