Today's best sales: Save on a Dyson vac, a Ninja grill and a high-def projector

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 25% off.

"Very pleased with this truly lightweight cordless vac," said one Amazon reviewer. "Could not believe how much it picked up on the first try and I am a robot vac addict, so my floors always look (and I thought) were spotless."

"The quality of Dyson products is always outstanding and this handy vacuum stick is no exception!" shared a fan. "I have two dogs with one that sheds tumbleweeds of hair and I keep my Dyson busy with that alone ... I love the way the stick can maneuver around furniture to catch all those dust bunnies and the multiple attachments fit into almost any space. Two speeds allows a longer battery run. Dyson is not cheap but the saying 'you get what you pay for' is certainly true!"

"My wife and I have had a few different vacuums in just the past year and they all claimed to pick up dog hair," explained another. "This is the only one that actually lived up to what they say it would do."

This gizmo creates a 20-foot mosquito protection zone within 15 minutes. Plop it in your backyard, pool area or patio, push a button, and enjoy up to 5.5 hours of protection (until it needs a recharge). The device uses heat- and scent-free repellent, but it doesn't get hot to the touch. You don't see steam or smoke coming out — it just works. When the cartridge is empty, pop in a new one. (It's also been reviewed by the Environmental Protection Agency for safety and effectiveness, and it's been deemed pet-safe.)

"My husband is a mosquito magnet. They seriously attack his face and any exposed skin," explained a shopper. "We tried this while sitting in our backyard around our propane fire table. I put the device between my son and husband. We sat out for about 30 minutes and neither of them had a single bite. We live in Florida so that's pretty remarkable."

If you sleep hot, these moisture-wicking pillows will help keep you comfortable. They're filled with a plush down alternative (100% polyester) that's encased in a soft, breathable sateen cover. 

"My husband and I are very picky about our pillows, and we are pleasantly surprised at how comfortable these are," said one five-star fan. "We are both side sleepers, and these have helped both of us have better nights of sleep. They support our necks without feeling like we are too propped up, and they offer enough give to help feel like our necks are being cradled. I'm glad I found these."

Crave the comfort of Crocs but don't love the look? These slides from the brand have foam insoles that make them comfy to wear all day long. Get them on sale in black, white or brown.

"I'm always looking for comfortable footwear as a busy mom of 3, and this is it!" wrote one shopper. "Has the sturdiness of much more expensive brands, plus the cushiony feeling of Crocs! These arrived this morning I could not take them off all day! I was on clouds in these! They're pretty too."

This absorbent stone bath mat is marked down to its lowest price all year. It was designed to soak up residual water like a champ, meaning it'll start drying as soon as you step on it. It comes with a slip-resistant under-mat, along with a sanding tool you can use to buff it every few months to keep it clean and maintain its absorbent properties. (Oh, and you can't forget about those sleek aesthetics!)

"Best purchase ever," raved one satisfied shopper. "This bath mat is a game-changer! No more soggy mats that need a wash every few days. This dries like magic and the bathroom always looks neat and tidy!"

Protect yourself and your home with a Ring Doorbell. This one offers night vision, two-way audio and live view, plus it supports both wired and battery-operated installations. Pair it with your go-to Amazon Echo devices: Something like an Echo Dot can double as the doorbell chime, while an Echo Show smart display can provide a live video feed. 

More than 162,000 Amazon shoppers give it a five-star rating. "This is the best system we've seen so far as far as clear picture, video and audio," said one fan. "The notification is instantaneous when a person is detected outside. We run it off its battery system and the batteries seem to last forever. Based on current battery levels, we will only need to charge them three or four times a year."

Take movie night outside with this high-definition Bluetooth projector. It wirelessly connects to your phone, but you can also use a cord to connect it to a laptop or plug in a Fire Stick. It has a built-in speaker so you don't have to invest in separate ones (but you can connect to some via Bluetooth pretty easily). And if you want the ultimate movie screen, this doodad can project a clear picture up to 300 inches wide.

More than 5,800 Amazon shoppers rave about it. "When I got the projector, it came with everything to set it up and use it right out of the box," said one shopper. "I tried every input type to ensure it worked. I was able to watch a movie off a flash drive, I plugged an [Amazon] Fire Stick into it, I've played with my Switch and my Xbox One on it. It has been an amazing little machine."

Apple's AirTag is one of the most powerful trackers you can get as an iPhone user. Simply connect it to your phone and use it to keep track of what matters — luggage, a purse, an expensive bike. You can also activate Lost Mode, which makes it play a loud sound. Grab this four-pack to put one in each family member's suitcase the next time you travel.

"I recently purchased an Apple AirTag, and I have to say, it's a game-changer for someone like me who tends to misplace things," said one user. "Setting it up was a breeze — just a few taps on my iPhone, and it was ready to go. The precision finding feature is fantastic; it leads you right to your lost item with directions and haptic feedback, which feels like magic. I've attached one to my keychain and slipped another into my backpack, and so far, they've saved me a ton of time and frustration."

If you want a rustic fire pit for grilling up some grub, this top-rated model is a solid pick. It has a food-friendly design that comes with a removable, FDA-compliant alloy steel grill grate for firing up meats, veggies and more in your backyard. The grill also adjusts up and down, swings left or right and has handles at both ends. (Just make sure you wear oven mitts or protective gloves to adjust it.)

"This was fairly easy to assemble and gives off great heat, enough to keep six to seven of us warm with one bundle of wood from the grocery store," said one shopper. "I love the additional burner for grilling. We've cooked corn, burgers and steak on this thing, and so far so good."

This electric outdoor grill is also an air fryer and a smoker that burns real wood pellets to give food a smokier flavor. Because it's electric, it uses only a small cup of wood pellets and cooks consistently and evenly — and it's big enough to cook up to 10 burgers at a time. It also comes with a built-in meat thermometer. It's easy enough for beginner grillers or smokers to use, and it's perfect for July 4th cookouts. 

"I've used the Ninja Woodfire outdoor grill once to smoke pork ribs on the Fourth of July. The directions recommended 2 hours of smoke time. However, after 1.5 hours of smoke time the ribs were perfect," said one self-proclaimed beginner. "The grill is big enough to fit a slab of ribs if they are cut, and it was very easy to clean up after using. I would recommend you not store the grill outside without purchasing a covering for it."
