Who should buy Roborock S4 Max

  • If you are looking for a robot vacuum with an outstanding vacuuming ability, at a reasonable price, the S4 Max is an excellent option for you.
  • If you have a multi-level home, the S4 Max is suitable for you because it can save up to four maps, so you can use it for all the levels in your home.
  • If you have a lot of obstacles or furniture in your home, you might be impressed with the S4 Max because it has a reliable mapping ability, that can navigate well around obstacles, to provide thorough cleaning.
  • If you live in a large house, you might want to consider the S4 Max because it can vacuum the entire floor at an impressive speed, and has a long battery life of 150 minutes; so it won't take a long time to clean, even if you live in a large house.
  • If you are looking for a robot vacuum that can clean well on your different floor types, the S4 Max might be the one you are looking for, because it has strong suction power that can vacuum well from bare floors to carpets.
  • If you have carpets in your home, the S4 Max may be a good fit for you since it can automatically increase its suction when it detects carpets, to provide more thorough cleaning.
  • If you have pets or active kids, you can count on the S4 Max because it has a strong suction power, and airflow that can easily pick up fine to extra large debris.

Who should NOT buy Roborock S4 Max

Verdict

This is our verdict of the Roborock S4 Max based on several hours of research of reviews from both experts and users.
Updated 14-04-2021

The Roborock S4 Max's vacuuming ability is so impressive that it beats out its other, more expensive, competitors. This is because most high-end robot vacuums are focused on enhancing their latest features and add-ons, making the product overly expensive. Manufacturers often neglect the fundamental feature of a robot vacuum, which is its vacuuming ability. They appear to be more inclined to provide increased convenience to their buyers.

The S4 Max, on the other hand, has enhanced vacuuming ability while maintaining a reasonable price. It supports several advanced features, but it still lacks some advancements present in the more expensive robot vacuums. The S4 Max may have a similar suction power of 2000 Pa, like in the S5 and S6, but it has a stronger airflow, enabling it to easily pick up fine to extra large debris.

The app offers a lot of options for customization. Within the app, you can adjust the suction mode from quiet, balanced, turbo, and max. It also allows you to set "no-go" zones, and select zone cleaning. You can also arrange a cleaning schedule for a specific room, or for the whole floor level, in addition to utilizing many more options. The app is rich in features that allow you to manipulate the robot vacuum according to your liking.

The S4 Max has a bigger dust bin than the S5 or S6, due to them having a mop that limits the dust bin's space. With a larger dust bin, the S4 Max can accumulate more dirt and clean more areas.

The LiDAR navigation system gives the S4 Max a much faster mapping ability. After its first run, it can already generate an accurate map that allows you to customize it easily. You can personally label the rooms according to what you want, unlike other robot vacuums that already have pre-listed options.

Overall, there aren't many drawbacks to the S4 Max. It actually has outstanding vacuuming ability, and is packed with many features, making it worth the investment.
