Roborock S4 Max Robot Vacuum Cleaner Benefits

Roborock S4 Max Robot Vacuum Review

From superior suction power to intelligent navigation and seamless integration into smart home ecosystems, the S4 Max offers unparalleled convenience and efficiency that triumph over other robot vacuums and other models. Let’s explore these key benefits in detail to understand why this stands out as a top choice for modern households.

Strong Suction Power

The Roborock S4 Max Robot Vacuum distinguishes itself with its exceptional suction power which has a maximum strength of 2000Pa. This robust capability enables the robot vacuum to clean a wide range of surfaces with ease, including low-pile carpets and hard floors.

We all know how navigating a high-pile carpet can pose a challenge for some robot vacuums due to the depth of the carpet fibers, which may hinder vacuum and movement. However, the Roborock S4 Max’s exceptional power overcomes this obstacle, making cleaning carpets, even on high-pile carpets, easy. It can reach deep into the fibers, lifting dirt and debris with ease, resulting in a thoroughly cleaned high-pile or low-pile carpet, floor, and room.

In comparison to many robot vacuums available in the market, the S4 Max delivers better performance in ensuring thorough removal of dirt, fine dust, and debris. Its powerful suction is particularly advantageous for pet owners, effortlessly eliminating pet hair and dander for a cleaner living environment.

Best of all, it has a trademarked Scratchsafe feature that allows its main brush to lift up and agitate fibers. This means no dust will be left behind and no hair will get stuck on the job. There’s even a jam sensor on the main brush to prevent any damage from happening.

Test it out yourself and you’ll see what we mean by strong power on this one!

Smart Navigation and Fast Mapping

Equipped with advanced LiDAR technology, the Roborock S4 Max exhibits intelligent navigation, automatic carpet detection, and mapping capabilities. Through precise mapping, the robot vacuum navigates individual rooms methodically, efficiently covering entire floor surfaces without missing spots. Its ability to create a detailed map, navigate different rooms, and go around obstacles to avoid collisions ensures a seamless session.

Speaking of, the no-go zones feature of the Roborock S4 Max also enhances both safety and efficiency by utilizing advanced sensors and mapping technology to detect invisible walls and create virtual barriers. This helps in preventing collisions with objects such as electric cords, table legs, and other obstacles. This feature not only safeguards the robot vacuum from potential scratches and damages but also protects valuable items in the home from accidental impacts. You also don’t need to use double-sided tape to create a barrier because this unit has an onboard Sensient sensor and cliff sensors.

We’ve tested this out ourselves and we give this an overall score of 5/5!

Customizable Cleaning Experience

Another notable benefit of the Roborock S4 Max robot vacuum lies in its four cleaning modes, which result in better performance. With options including Quiet, Balanced, Turbo, and Max modes, users can customize the intensity based on their specific needs and preferences.

This versatility ensures that the S4 Max can do a better job at tackling various messes, from everyday dirt and debris to more stubborn stains and pet hair, resulting in a thoroughly clean house. Whether it’s a quick spot clean or a comprehensive session, the S4 Max’s multiple modes deliver exceptional results, elevating the overall experience for users.

People can also customize schedules and designate specific zones via the Roborock app, allowing for tailored routines that suit individual preferences and lifestyles.  Have we also mentioned how easy it is to start a session? Simply press and hold the power button to activate a session or long-press the home button to active spot mode — it’s that easy! Alternatively, you can opt to power this unit using the app.

Seamless Integration into Smart Home Ecosystems

The Roborock S4 Max seamlessly integrates into smart home ecosystems, offering compatibility with popular smart home assistants like Alexa and Google Home. With voice commands or through the Roborock app, users can effortlessly control and monitor the robot vacuum, providing convenient hands-free operation and real-time status updates.

How Long Does the Roborock S4 Max Last?

Roborock S4 Max Robot Vacuum Review

The Roborock S4 Max has an impressive battery life, lasting up to 180 minutes on a single charge. In our test, we found that this extended battery life provides ample cleaning time for most households before requiring a recharge via its dock.

The S4 Max is also equipped with a smart battery management feature. If it detects that it’s running low on battery in the middle of a session, the S4 Max will automatically return to its charging dock to recharge. So if you place the charging dock in your dining room, it has no problem finding its way back to its station from the current location or room. Provided of course that the signal has no barriers, which you can check via the Wi-Fi indicator light.

After taking a break, the S4 Max must latch off of its dock and go back to doing its job of making your home clean. This feature prevents the robot vacuum from stopping mid-session and guarantees that it’s always ready to tackle the next task.

What is the Difference Between Roborock S4 and S4 Max?

Roborock S4 Max Robot Vacuum Review

The main difference between the Roborock S4 and S4 Max lies in their respective features and capabilities. The S4 Max has a stronger suction power of up to 2000Pa compared to the S4 resulting in a more thorough performance. The S4 Max also has a larger dustbin capacity of 460ml, providing greater convenience by reducing the frequency of emptying.

Aside from that, the S4 Max includes advanced features like no-go zones and multi-level mapping, allowing users to designate areas to avoid and customize preferences for different floors or rooms. On the other hand, the S4 lacks these, making it more suitable for users who prioritize basic tasks without the need for advanced customization options.

While both the Roborock S4 and S4 Max are excellent choices, each model caters to different user preferences and needs. The Roborock S4 is ideal for users seeking reliable performance without the need for advanced features, making it a great option for those on a budget or with simpler requirements.

Alternatively, the S4 Max is well-suited for users who prioritize enhanced cleaning capabilities, customization options, and convenience, making it a top choice for households with larger floor plans, multiple levels, or specific preferences.

Ultimately, the choice between the two models depends on the individual user’s priorities and preferences.

American-born New Yorker Linda Johnson has been fascinated with robotic machines since she was a teenager, when her father, a surgeon, would introduce to her the machines that he used to perform keyhole surgeries. This interest led her to pursue a tech degree at the University of Washington, where she met Sota Takahashi. They married and now have two children. Linda’s father developed dementia later on and was given a robot pet as a companion. She saw how much having a robot pet friend helped her father, which is what led her to create this website and advocate to spread word about robot pets and how they can help both children and the elderly.
