It used to be that when it came to robot vacuums, there was Roomba and then there was everything else. These days, however, things have changed a bit… there’s Roomba and Roborock, and then there’s everything else. Roborock has made a name for itself by offering premium robot vacuums with strong suction and high-end features for hundreds less than comparable Roomba models. And today, you can use the coupon code ROCK4NEWY to save $90 on the company’s most popular model, the laser-guided Roborock S4 Robot Vacuum.

Here are the key details 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.
