Friday's top deals: Kindle eBook credit, Bluetooth headphones, and more

Amazon's line of Fire tablets are already affordable, making them perfect for giving to children or using around the house for media consumption. While they might not replace your laptop, they won't break the bank either — especially if you make the most of this limited-time sale on previous-gen Fire tablets at Woot. It includes the 2017 Fire HD 8 and 2015 Fire HD 10 in new condition with prices from just $55.

Amazon has the Eufy RoboVac 30C 1500Pa strong suction self-charging robotic vacuum cleaner for just $199.99. That's a huge direct discount and the lowest price we've seen for the 30C on Amazon. Eufy's RoboVac 30C has a tiny 2.85-inch body so it's small enough to fit under a lot of furniture. It comes with boundary strips, too, so you can keep it out of areas you don't want it to go. The RoboVac has BoostIQ technology to automatically increase suction power when that extra strength is needed, and you'll get up to 100 minutes of constant suction with little noise pollution.

Before this deal, neither option had ever gone on sale for less than $75.
