Today's best sales: 40% off a bestselling walking pad, 30% off a space heater

This compact treadmill is only 3.5 inches high and 39 inches long, so you can slide it under your sofa or bed when you're not using it. It's also only 22 pounds, which is light enough that you can probably pull it out on your own (but just heavy enough to make you sweat a little while doing so —heh).

This handlebar-free tread, designed for walking, goes up to 3.8 mph and shows your speed, distance, time and even calories burned. Also great: It has an anti-slip belt and a strong damping system, so you won't make too much noise. Control it with the included remote. Want to amp up your strength workouts? It also vibrates so you can add a little balancing practice to your exercises.

"If you’re looking for a convenient, effective and portable fitness solution, this is it!" said one five-star fan. "This has been a game changer as a busy mom trying to stay fit at home. It's light and compact, but still powerful. I love being able to use the remote control to adjust speed and see how many steps and miles I am walking. It's easy to transport and I can slide it under my bed after use. Easily my best purchase of the year!"

This little space heater packs a punch. It offers seven heat settings and two quiet fan settings, and it oscillates to heat up a room in seconds. It will automatically shut off if it starts to overheat or if it's accidentally tipped over. If your feet get especially chilly or you want to use it to keep warm on your patio, it's a solid buy.

"The heater warms up the whole bedroom," noted one customer. "It's very affordable and works wonderfully. It's lightweight so can be easily moved where needed. The cord is a good length, so it gives you options for a replacement in a room. The heater has a lot of settings that can be used, which is a nice feature. It puts out a lot of heat, which is a plus."

If a standard air fryer simply won't suffice for your cooking needs, then behold this one from Drew's cookware line. The extra-large size and TriZone technology means you can cook two different foods at once. You can choose from six available colors, but White Icing (pictured here) is on sale today.

"I love, love, love this," said one shopper. "It is a beautiful addition to my countertop. I use it for air frying the most but I also have used it for the other functions and I'm extremely pleased. I'd buy it again. A little tip: Set the time and temperature a little less than you would for a regular oven. Also, the quality and crisp you'll get on your food is amazing. The amount you can cook in it is also great."

This cozy sweatsuit looks like Oprah's favorite Spanx set, but you can get it on sale for just $43! (In comparison, the Spanx version costs over $200.) It's also Amazon's No. 1 bestselling tracksuit, with over 3,000 five-star reviews. Get it on sale in over 20 colors.

One customer shared they've already bought multiples. "I purchased this tracksuit in light khaki and coffee," they said. "I love the look and feel of these outfits! It is a smooth, silky-like texture that tends to flow smoothly over curves. ... This outfit doesn't disappoint!"

Hate vacuuming? Get a robot to do it for you while it's on sale for its Black Friday price — also its lowest price ever! Some highlights: It cleans in neat rows thanks to Smart Navigation features. (Think more precision, less bumper cars.) You'll get up to two hours of cleaning on a single charge, and if it isn't done when the charge runs out, it will pick up where it left off after some rest. And it can go just about anywhere: Use it on carpet, tile or hardwood floors.

This little robovac has over 34,000 five-star reviews on Amazon. "Love the job this Roomba does," said one reviewer. "I was shocked at how much dust/debris it picked up in a room I thought was clean. Charging is easy, cleaning is relatively easy, and the machine is relatively quiet compared to a regular vacuum."

This bestselling tub, tile and floor scrubber is great for power washing a bathroom, kitchen, walls and more. It has a long, extendable handle and comes with six brush heads, plus the rechargeable battery lasts for up to two hours. It's lightweight too, so it's not hard to lift high or carry from room to room — and it's Yahoo editor-approved.

"Best cleaning purchase I've ever made," said one five-star fan. "Wow, just wow. I have a messed-up back, and this baby has let me stay cleaning again! The extend feature is absolutely amazing. Doesn't take long to charge, and a charge lasts several uses. Plenty of attachments included, and additional ones can be easily found here on Amazon. If I could I'd give this six stars."

If you struggle with getting enough water pressure without blowing up your monthly bill, this high-flow showerhead is designed to make it feel like you're rinsing off in a rainforest. The 4.1-inch head provides a broader coverage area and gives you all the sensations of standing under a tropical waterfall without having to hop on a plane. Made with corrosion-resistant chrome, it also comes with a built-in water filter and has a self-cleaning nozzle that prevents mineral build-up — that means nothing can get between you and your rejuvenating shower.

"Holy gosh to goodness," shared a five-star fan. "That rain mode is nothing short of heavenly! I just want to be in the shower all day and night now. Addictive, yes! Be warned!"

One of Yahoo's shopping writers tried these popular leggings and said they're "just as good as Lululemon." While that's a big claim, Amazon shoppers tend to agree. The soft fabric offers just the right amount of compression and the leggings come in two inseams to offer a better fit. 

"Flattering and soft," wrote one reviewer. "It's not so super tight that it squeezes and turns your sides into a muffin top, but tight enough that it's flattering on your body."

More than 169,000 Amazon shoppers have given these bestselling pillows a five-star rating. Why? They're extra fluffy and feel like real down, like the ones you'd find at a high-end hotel. However, they're also affordable — especially when they go on sale. 

"My friend bought this for her guest room when my husband and I spent the night, and we were amazed at how comfortable the pillows were," said a shopper. "It was one of my best nights of sleep in a while! So I had to buy them for our house, and I'm glad I did. They are full-looking and feeling, but not so full that it's uncomfortable to sleep on."

If you don't have enough closet space to store bulky sweaters, shoes or linens, try stashing them under your bed in these flexible containers. They're sold in a pack of four and each one holds up to 90 liters of stuff. 

"It has really helped us to utilize unused space under our bed, and freed up some much-needed closet space," said one shopper. "The material feels relatively strong, and the clear lid makes it easy to see what’s inside without having to search through each individual container. It's been a game-changer for organizing coats, bedding and other bulky items."
