Review: Roborock S7 Max Ultra

Things are heating up in the Roborock product jungle. The company decided without further ado to release another model in the S7 series with the Roborock S1.199 Max Ultra (RRP 7 euros). At the same time, this creates a lot of confusion. After all, with the Roborock S7 MaxV Ultra (1.399 euros RRP) and the Roborock S7 Pro Ultra (1.199 euros RRP), there are already two very similar models from last year.

In terms of features and performance, the new Roborock S7 Max Ultra is on par with last year's model, the Roborock S7 MaxV Ultra, but places below the current top model  Roborock S8 Pro Ultra (1.499 euros RRP) .

 The differences lie in the details: For example, the S7 Max Ultra does without the RGB camera of the S7 MaxV Ultra, which transmits a live image to the smartphone. In return, it offers higher suction power - specifically 5500 Pa compared to the 5100 Pa of the S7 MaxV Ultra - and integrates hot air drying for the wipes directly in the station.

 Here is a comparison between all current Roborock models:

Roborock S7 Max Ultra: design and finish

The Roborock S7 Max Ultra is sturdy and compact enough to handle the challenges of daily house cleaning. The design of the vacuum robot is mostly unspectacular. It is available in the colors white and black. This makes it suitable for different furnishing styles.

The vacuum robot is parked backwards in the station

To clean the wipe, the vacuum robot moves backwards into the station.

The vacuum robot itself has a diameter of 35,3 centimeters. Typically, there is a LIDAR tower at the top, which is responsible for mapping and navigation. Thanks to its total height of 9,65 centimetres, it can easily vacuum and wipe under most furniture.

The vacuum robot hides a 350 milliliter dust container under its lid, which it automatically empties into the disposable dust bag of the cleaning station after each cleaning process. This is an important difference to the classic Roborock S7, whose suction station could also be operated without a bag. However, this is no longer possible for the S7 Max Ultra and S7 MaxV Ultra models. The bags cost between 1 and 2 euros. On average, you change the bag every six weeks.

The lid of the robot vacuum is open and the dust container has been removed

A HEPA filter in the dust chamber prevents fine dust from getting into the air.

The Roborock S7 Max Ultra uses the so-called VibraRise system for wiping. This is a vibrating wiping plate that is automatically raised by 5 millimeters at carpet edges, so that simultaneous vacuuming and wiping is possible. Neither the mop plate nor the water tank can be removed. Both are permanently installed.

The Roborock Ultra Station and the robot vacuum are well matched.

The vacuum robot automatically fills up with fresh water by using the Ultra Dock cleaning station. The station is equipped with a 3 liter fresh water tank for this purpose.

In addition, the station has a 2,5 liter waste water tank, into which the waste water is directed after cleaning the station and the mop. After cleaning is complete, the mop is dried with hot air. You don't have to buy a separate drying module, which saves costs (approx. 70 euros) and effort.

The water tanks are closed and have a carrying handle.

In terms of build quality, the Roborock S7 Max Ultra upholds the manufacturer's high standards. Its solid construction and precise workmanship ensure that it can withstand intensive use. The scope of delivery is a bit sparse as usual and offers no other parts apart from a replacement dust bag. It is best to order more wipes at the same time!

Roborock S7 Max Ultra: Setup and App Usage

Setting up the Roborock S7 Max Ultra is a breeze thanks to the detailed instructions in the Roborock app. As soon as the vacuum robot is connected to the power supply and the app is downloaded, the application guides you through the setup process step by step. No questions remain unanswered. Each setup step is carefully explained and the most important functions of the vacuum robot are presented in detail.

The Roborock app itself is clearly structured and intuitively designed. All functions and settings are easily accessible, which makes using the vacuum robot easy.

With the quick mapping feature, users can create a space map in minutes. Up to four such room cards can be saved at the same time, which makes it easier to use the vacuum robot in multi-storey apartments or houses. The Roborock S7 Max Ultra independently recognizes the appropriate room card for the floor.

If changes are required to a created room map, these can easily be made later. In edit mode, rooms can be merged, split and renamed. In addition, restricted zones can be defined in which the vacuum robot should not clean.

Whether vacuuming and wiping, just vacuuming or just wiping - the Roborock S7 Max Ultra is able to clean all rooms, individual rooms or specific zones. The suction power can be adjusted in four levels and the wiping intensity in three levels. All of these settings can be set individually according to cleaning schedules.

Roborock S7 Max Ultra: practical test

In my practical tests, the Roborock S7 Max Ultra impressively demonstrated its impressive suction power of 5500 Pa. He has shown that he can handle all types of household dirt. Whether it's animal hair on shaggy carpets or small stones and stubborn dust on tiles, parquet or carpets - the vacuum robot masters its tasks reliably.

In a specific test where I spread 100 grams of household dirt on tiles and carpets, it picked up 96 grams from the tiles and 93 grams from the carpets. Despite the slightly higher suction power, there is no significant difference to the Roborock S7 MaxV Ultra, which delivers very similar results.

The cleaning station with a view from above

Left the dirty water, in the middle the fresh water and on the right the dust bag.

To clean corners and edges, the Roborock S7 Max Ultra uses a fast rotating side brush with fine bristles. It sweeps the dirt to the central main brush. However, even this robot vacuum does not get enough into difficult corners, so that dirt occasionally gets stuck deep in the corner.

This main brush consists of a rubber roller without bristles, which makes it particularly easy to maintain. Hardly a hair got tangled in it after a week of daily use.

A small downside to this brush is that it occasionally squeaks when the slats touch the floor - including a bit of a racetrack feeling during the cleaning cycle. The double brush technology of the latest Roborock S8 would be even more efficient, but this technology is currently only reserved for the top model.

Hair rarely gets tangled here.

Thanks to its Reactive Tech Obstacle Avoidance, the Roborock S7 Max Ultra can avoid most obstacles. Compared to the camera-based Reactive AI 2.0 of the Roborock S7 MaxV Ultra, however, this technology works a little less precisely with smaller obstacles. He mercilessly dragged around cables and flat toys in the test.

However, the vacuum robot recognizes larger obstacles from a height of three centimeters very well and avoids them precisely. His navigational skills seem goal-oriented, so he never got lost on his daily cleaning run.

It does not recognize small obstacles under three centimeters.

The S7 Max Ultra's VibraRise mopping module presses firmly on the floor and removes fine dust particles with 3000 vibrations per minute. Despite its mopping function, the vacuum robot, like most of its kind, is less suitable for stubborn stains.

Water stains in the bathroom or dried, sticky stains are difficult to remove. However, this is not a specific weakness of this model, but a general limitation of vacuum robots with a mop plate. Vacuum robots with rotating mops are usually better suited for wiping jobs.

The Roborock S7 Max Ultra wipe is attached with Velcro

The wipe can be removed and attached quickly and easily.

Despite everything, the S7 Max Ultra is ideal for wiping the apartment every day and removing fine dust. Thanks to its VibraRise ability to automatically raise the mop on carpets, it can vacuum and wipe at the same time without the need for manual intervention.

After completing the cleaning work, the Roborock S7 Max Ultra will automatically return to the base station and perform a self-cleaning there. He empties his dust container, washes the mop with fresh water and then dries it with warm air for about three hours to prevent odor build-up. The dock also cleans itself and quickly removes any dirt that falls off the mop.

A look inside the Roborock S7 Max Ultra Station

The battery performance of the vacuum robot is remarkable. It cleans my 80 square meter apartment in one go without any problems and in the end even has 67 percent of the battery charge left. In a single family home, it could therefore clean several floors with a single charge.

Should the battery run out during the cleaning process, the Roborock S7 Max Ultra has enough intelligence to return to the charging station on its own, charge itself and then continue cleaning right where it left off.

Roborock S7 Max Ultra front charging contact

The charging contact is on the side of the vacuum robot.

A full charge cycle took about four hours in my tests. This may seem long at first glance, but it is an acceptable loading time for a vacuum robot, so there is hardly any downtime. Some comparable models charge for more than six hours!

Roborock S7 Max Ultra Review Header

S7 MaxUltra


Very good build quality
Easy to set up and use
User-friendly Roborock app
Good suction power with solid rubber roller
VibraRise for simultaneous vacuuming and mopping
Effective self-cleaning with RockDock Ultra Station


Obstacle detection not always reliable
Wiping performance on stubborn stains


Despite a somewhat confusing naming and positioning in the Roborock product line, the Roborock S7 Max Ultra offers excellent value for money.

With its strong suction power, effective self-cleaning function and intelligent navigation, it enables a stable and reliable cleaning experience. It masters everyday cleaning tasks with ease and contributes significantly to a clean and dust-free environment.

Minor weaknesses, such as the occasional insufficient obstacle detection, have to be taken into account, but they don't diminish the generally positive overall impression. If you are looking for a reliable, powerful and affordable automated cleaning solution, the S7 Max Ultra will no doubt be a smart choice. However, there is no reason to switch from a Roborock S7 MaxV Ultra or S7 Pro Ultra.

    Hello Timo,

    Thank you for the insightful test. At the moment I'm still hesitating between the S7 Max Ultra and the S7 MaxV Ultra. With the S7 MaxV Ultra you can remove the wiper plate and water tank. Does that make it easier to clean, or how much sense does that even make? How would you base the purchase decision?

      Hi Susanne,

      whether the mop plate is removable or not makes little difference. All you have to do is clean the wipe that I regularly put in the boil wash myself. The built-in water tank can become a problem if the water is in it for a long time. One would have to wait and see to what extent deposits such as lime cause problems.

      But: The S8 Pro Ultra also has a built-in tank and there are no known problems so far.

    Hello Timo,
    Would you also recommend the S8 or S7 for oiled wooden floors? How wet does the floor get when mopping and does the microfiber cloth leave scratches on the floor or is it soft enough?

    Thank you,
    (also a) Susanne
