Roborock S4 Max Robot Vacuum

What is the Roborock S4 Max

Introduced in September of 2021, the Roborock S4 Max is the successor to the original Roborock S4 robot which was a highly competent, very well balanced vacuum-only robot. The S4 Max took what worked with the original and improved upon it.

The S4 Max improved upon its predecessor in five significant ways:

  1. The S4 Max includes Carpet Boost, allowing it to automatically increase suction when the robot determines it is on a carpeted surface.
  2. Multiple floor map support was increased from three to four maps.
  3. With the S4 Max, Roborock increased the dustbin by 40mL to 460mL.
  4. Scheduling functionality was a major improvement, including time-of-day scheduling as well as being able to schedule cleaning by room name.
  5. When navigating or cleaning, the Roborock S4 Max now has improved climbing ability when moving from room-to-room or when climbing uneven surfaces.

Standout Features

The Roborock S4 Max is packed with modern technical innovations while still finding a price point that is inexpensive when compared with its competitors. The S4 Max boasts the following capabilities:

  • PreciSense LiDAR system which spins at 3000 RPM and leverages a suite of algorithms to provide precise floor plan mapping and navigation.
  • Roborock's Sensient sensor array includes jam and cliff sensors which ensure the S4 Max can navigate even in complicated environments.
  • No-Go Zones and Invisible Walls to ensure the S4 Max can only goes where it should.
  • Automatic Room Recognition means the Roborock S4 Max can automatically identify what map and room it has been placed in.
  • The S4 Max supports both Room Cleaning as well as Zone Cleaning with up-to 5 zones at once.
  • Automatic Carpet Boost increases suction power to the maximum level when carpet is detected.
  • The Roborock S4 Max has a washable E11 rated air filter which captures up to 95% of airborne particles including allergens, fine dust, mold and pet dander.
  • The Scratchsafe floating main brush leaves both carpets and hard floors clean and scratch free.
