Black Friday is always a stellar time to look for discounts on new products and new technology for your home. The Roborock S4 Robot Vacuum (opens in new tab) was just released about two months ago, and you can already score $100 off its purchase at Amazon when you clip the coupon on its product page. That brings its cost down to $299.99 for the first time ever. Don't wait too long on this offer, as there's no guarantee that it'll wait around through Black Friday now that it's live.
Roborock's smart S4 robotic vacuum cleaner features a high-precision laser navigation system that scans the rooms in your home to create a real-time map that's extremely accurate. Its 2000Pa suction is powerful enough to pick up AA batteries, so you'll want to be careful what you're vacuuming over. It picks up dirt, dust, and pet hair with ease, though it's not recommended for use on high-pile carpets.
With the Roborock app, you'll be able to control this smart robotic vacuum cleaner even while you're away from home. Simply use the app on your smartphone or tablet to clean, set areas for the vacuum to stay away from, and more. The vacuum cleaner's large 5200mAh battery lets it clean for over 150 minutes on a single charge, but the best part about it is that whenever the battery is dead, the robot vacuum returns to its charging base all on its own so you never end up stepping on a dead robot in the middle of a messy floor.
If you're trying to spend less than $300 on your robotic vacuum, Roborock's E20 Robot Vacuum is also on sale today at $100 off. Now down to just $199.99, this model has one helpful feature the S4 above does not: a mop! That's a pretty handy feature that we think is essential.
