Roborock really blew up in 2019 and became a robotic vacuum brand that many people recognize as offering quality on par with Roomba, but with even more features in many cases. For example, the company’s best-selling flagship Roborock S6 Robot Vacuum has built-in mopping functionality to complement its insanely strong suction. The Roborock S4 is just as strong, but it ditches the mopping feature to trim $250 off the S6’s price tag. Of course, today is Black Friday so you get an even bigger discount — the $400 Roborock S4 is on sale for just $299.99 right now!
Here’s some detail from the product page:
- A high-precision laser navigation system scans your room at 300RPM, creating a real-time map of your home that is accurate to up to +/- 2cm.
- Comprehensive Roborock app control, including map saving, selective cleaning, no-go zones, and power setting, give you total control of S4 no matter where you are.
- Intense 2000pa Suction, enough to lift AA batteries, easily picks dust off floors and can even drag trapped dirt from deep inside low-pile carpets. Do not suggest to use it on high-pile carpets.
- Supersized 5200mAh LiPo battery, good for over 150 minutes of non-stop cleaning, is more than enough to clean most homes in one session.
- An elegant transparent design adds a touch of style, and also makes checking the dustbin easier. A glance through the shell is all you need to do.
