Roborock S4: Robotic Cleaner with Intelligent Mapping and Great Suction

Roborock S4

There is nothing more important for thorough vacuuming than strong suction, and the model tested for this Roborock S4 review can provide it. Its motor creates a pressure of 2000 Pa which is enough for deep cleaning on any floor surface.

Dimensions

The dirt compartment of this vac has a capacity of 400ml. It's relatively small, especially when compared to the Roborock E4, a similarly-performing model in the same price range as the S4 but with a much larger dustbin (680ml).

The Roborock S4 size is 5.04 inches in height, 13.90 inches in width, and 16.46 inches in depth. It weighs 8.48 pounds, so carrying it to another floor shouldn't be too difficult.

Features

The cleaner uses the LidarVision system with laser-guided navigation. The smart pathing feature of this unit allows it to learn the surface each time it's set to clean instead of simply using the maps stored in its memory. This way, it easily navigates around new objects in the room.

The Roborock S4 specs let the cleaner perform impressively on both bare floors and carpets. The main brush uses a combination of rubber and bristles. The cleaner vacuums hair, and both large and small debris thanks to an automatic surface type adjustment system, so it changes the rotational speed of the brushroll depending on the type of surface. There is also a side brush that starts to spin faster when the cleaner gets close to the walls.

In Balanced cleaning mode, the bot can clean for up to 150 minutes. Nevertheless, in its weakest cleaning mode (Silent), it can last up to 200 minutes. It takes a little longer than 2 hours to recharge.

The Roborock S4 uses the E11 filter that traps allergens and dust. The extra one is included in the kit. It's recommended that you replace it every 4 to 5 months, according to the manufacturer. The brushroll needs to be cleaned with the help of an included cleaning tool.

You have complete control over the cleaner's functions thanks to the MiHome app. It can also be used to create boundaries around small items such as toys or cables. The app also sends push notifications, but the vac itself has a built-in speaker for voice notifications.

The model has a great navigation system and superior cleaning performance. This way, it deserves to get a 9/10 for the provided features.

Design

The Roborock S4 is entirely black, but the protective bumper that surrounds it is dark-silver in color. The top panel has a glossy finish and incorporates a laser-navigation system (that protrudes from the surface) and two control buttons (Power and Dock). When the cleaner is less than 20% charged, a white LED indicator on the Power button turns red. The body is made of dense plastic, and the bottom wheels are made of rubber. These wheels allow the cleaner to pass over the thresholds that are up to 0.79 inches high.

Although the glossy top surface may be easily scratched, the overall design of the unit appears to be quite practical. As a result, I give it a 9 out of 10.

Conclusion

As a conclusion of this Roborock S4 robot vacuum review, I can say that this cleaner deserves to be referred to as one of the most powerful. It has a high suction level and a large battery capacity. Its cleaning performance is almost automatic, so all you have to do is just set the cleaning mode.
