The Roborock S4 Max delighted top testers with its automation features, as well as how it was able to clean bare floors. They liked that its companion app was easy to use and that it is also equipped with a HEPA filter.

Unfortunately, the S4 Max has high maintenance needs and struggles on low pile carpets.

What the brand doesn’t always tell you…

our Verdict

The Roborock S4 Max had product testers quite happy with its automation features. During their tests, experts from Rtings could map out their cleaning area through the easy-to-use Roborock app and set up both virtual boundaries and no-go zones.

They could also schedule cleaning times, remote pilot it, and adjust the suction power settings. These are automation features that the S4 Max shares with the Roborock S4.

Testers at Digital Trends were also impressed with how it maneuvered around obstacles. They credited this to its use of Laser lidar navigation which is lacking on the ONSON GOOVI F007.

The S4 Max also impressed testers with its cleaning ability, as it could eliminate 99% of large debris and small debris and 100% of pet hair on bare floors.

Overview

The Roborock S4 Max is a mid-tier robot vacuum that was first announced in 2021. It is one of the best rated vacuum cleaners for users that prefer autonomous cleaning, and with a run time of up to 204 minutes, it is well suitable for cleaning medium to large size rooms.

It has a dirt compartment that can hold up to 0.42-liters of debris, which is even larger than some highly rated robot vacuums like the Roborock H7, which can hold up to 0.25-liters.

The S4 Max also comes equipped with an anti-allergy HEPA filter to filter out up to 99.99% of allergens, and it offers four different power suction modes to choose from Quiet, Normal, Turbo, and Max.

When carpet mode is switched on, it can detect carpets and switch to Max for effective cleaning. In this setting, the S4 Max also doesn’t get as disruptive, as it has a fairly low noise level of 69 decibels.
