You can get the iRobot Braava Jet M6 Smart Robot Mop, currently on sale for $119.99 on StackSocial. PCMag gave it an “excellent” rating for good reason: it mops in straight, efficient rows, maps your home, and can be controlled via the app or Alexa.

The m6 is ideal for homes with hardwood, tile, or stone floors and works well in open layouts or multi-room setups. It uses vSLAM navigation to create a smart map of your space, where you can also set “Keep Out Zones” to avoid dog bowls or play areas. The battery lasts for about 150 minutes, and it’ll automatically return to its dock and resume cleaning where it left off. You also get two cleaning modes (wet mopping and dry sweeping) and a 15-ounce water tank that handles most messes without frequent refills. The app lets you schedule cleanings, choose specific rooms, or just send it off to mop up a spill on command.

Still, don’t expect miracles. While it does a solid job on everyday grime and dried spills, it won’t scrub out stubborn stains the way a human can. You’ll also need to buy the cleaning pads and solution separately. That said, at under $120 for a Grade “A” refurbished model with a one-year warranty, it offers a lot of functionality in a small, quiet package. It’s especially useful if you already own a Roomba vacuum—the two can work together to vacuum and mop your floors in a seamless sequence. For anyone looking to minimize daily maintenance without sacrificing clean floors, this robot mop makes a compelling case. It also comes in white.

How long do Black Friday deals really last?

Black Friday sales officially begin Friday, November 28, 2025, and run throughout “Cyber Week,” the five-day period that runs from Thanksgiving through Cyber Monday, December 1, 2025. But Black Friday and Cyber Monday dates have expanded as retailers compete for customers. You can get the same Black Friday sales early, and we expect sales to wind down by December 3, 2025. 

What stores have the best sales on Black Friday?

Nowadays, both large retailers and small businesses compete for Black Friday shoppers, so you can expect practically every store to run sales through Monday, December 1, 2025. The “best” sales depend on your needs, but in general, the biggest discounts tend to come from larger retailers who can afford lower prices: think places like Amazon, Walmart, Target, Best Buy, and Home Depot. You can find all the best sales from major retailers on our live blog. 

Are Black Friday deals worth it?

In short, yes, Black Friday still offers discounts that can be rare throughout the rest of the year. If there’s something you want to buy, or you’re shopping for gifts, it’s a good time to look for discounts on what you need, especially tech sales, home improvement supplies, and fitness tech. Of course, if you need to save money, the best way to save is to not buy anything. 

Are Cyber Monday deals better than Black Friday?

Black Friday used to be bigger for major retailers and more expensive tech and appliances, while Cyber Monday was for cheaper tech and gave smaller businesses a chance to compete online. Nowadays, though, distinction is almost meaningless. Every major retailer will offer sales on both days, and the smart move is to know what you want, use price trackers or refer to guides like our live blog that use price trackers for you, and don’t stress over finding the perfect timing.
