Roborock Models

Currently, there are 6 Roborock robot vacuum models.

  1. Roborock S6
  2. Roborock S5
  3. Roborock S5 Max
  4. Roborock S4
  5. Roborock E35
  6. Roborock E25 / 20

These Roborocks can further be divided into a few sub-models.

Roborock S Series

2-in-1 Robot Vacuum & Mop

moderncastle-fs-table__image

Roborock S6

The Roborock S6 is the most advanced robot Roborock makes. In our tests, cleaning performance was pretty good at an 89%, but it did seem to struggle more than we would have expected on carpets. Compared to other Roborock models, it has more advanced navigational features and specific room cleaning. It also has the ability to mop, runs for 150 minutes, and is only 67 dB loud (in balanced mode).Check Price

Mid-Range, Tech-Savvy Robot

moderncastle-fs-table__image

Roborock S5

The Roborock S5 is a slightly stripped down version of the S6 and S5 Max, while still maintaining all of the essential features. In our tests, the S5 scored the same as the S5 Max, a 91% overall. The S5 was slightly better on low pile carpet and slightly worse on high pile, compared to the S5 Max. The Roborock S5 has a less advanced navigation and doesn’t have room by room cleaning. In addition, it’s slightly louder than the S6 and S5 Max. However, beyond that it’s similar to Roborock’s other flagship models. It has the same run time, suction, dust bin, battery, and square foot coverage as the Roborock S6.Check Price

A Smarter 2-in-1 Robot Vac and Mop

moderncastle-fs-table__image

Roborock S5 Max

The Roborock S5 Max is a 2-in-1 robot vacuum mop combo unit that prioritizes mopping performance. In our tests its cleaning performance was similar to what we saw on the S6, scoring a 91% overall. Like the S6, its greatest struggle was fine debris on carpet. The S5 Max has most of the same features as the S6, however, it’s louder and has a slightly smaller dust bin. In exchange for that, you get a water tank that’s more than double the size at 290 ml. The larger water reservoir allows the S5 Max to mop huge areas, while still functioning as a more than capable robot vacuum cleaner.Check Price

Smart & Budget-Friendly Robot

moderncastle-fs-table__image

Roborock S4

The Roborock S4 is a more basic version of the S6. Notably, the S4 does not have a mopping attachment, so it’s a vacuum only. However, that is the primary feature you give up by going with the S4. It was amazingly good in our cleaning tests, scoring a 96% overall. Its high carpet cleaning score was particularly impressive, scoring a 97%. The S4 has the same run time, battery, suction, and square footage coverage as the S6.Check Price

Roborock E Series

Robot Mop & Vacuum Combination

moderncastle-fs-table__image

Roborock E35

The Roborock E35 is part of Roborock’s older and more basic models. Its navigation is simpler, no laser navigation, no map memory, and it uses the more typical bump-and-continue style of cleaning. It still includes the mopping attachment and has the same suction and run time compared to the S6. In our cleaning tests it scored a solid 92% overall. Even though it’s a few years old, it’s a solid robot at a reasonable price point.Check Price

Low to Mid-Range Price; Solid Value for 2-in-1

moderncastle-fs-table__image

Roborock E25

The Roborock E25 is the simplest robot that Roborock builds. Cleaning performance was still good. In our tests it scored an 89% overall, with high pile carpet being the worse. It uses a smaller battery and therefore has a shorter 100 minute run time. In addition, the battery only allows it to cover 1,500 square feet. For most users, we think it’s worth spending the extra to get the E35. Nevertheless, the E25 is still a solid robot.Check Price

The Differences

  • Dust bin capacity: The Roborock E Series vacuums (E25 and E35) have the largest dust bins, with a 640 mL dust bin capacity. The S Series robots max out at the capacity of 480 mL, with the S5 Max being the smallest at 460 mL.
  • Mopping: All Roborock vacuums listed here have the mopping feature except for the S4.
  • Mapping: All Roborock vacuums listed here have mapping technology except for the E35 and E25.
  • Battery: All of the Roborocks listed here have a battery capacity of 5,200 mAh, except for the E25, which only has a 2,600 capacity.
  • Area coverage: The Roborock S series covers about the same amount of area in a single charge (approx. 2600-2700 SF). The E35 is a little less at 2,100 SF and the E25 has the smallest area coverage, only 1,500 SF.

Cleaning Performance

The cleaning performance of Roborock robot vacuums varies by model, however, all are similar and quite good.

A few of the Roborocok models have advanced navigation and digital mapping technology. The maps are generated directly on the Roborock app and shows a digital representation of current robot status and cleaning history.

You can use your finger to draw “no go zones” which tell the Roborock not to clean past that point in the map.

All Roborock models listed in this review come with smart digital mapping with the exception of E35 and E25.

Accessories

Here’s a quick rundown of what accessories you’ll get with each Roborock robot.

S4 Accessories

The Roborock S4 is the most basic accessory package. The exact list of parts and accessories includes:

  • Charging station: provides a centrally located place for the vacuum to recharge between cleaning cycles
  • Spiral brushroll: this tool is mainly used for cleaning carpeted floors and spins as it cleans, to agitate and collect debris from deep within the fibers of various flooring types
  • Dust bin: a decent-sized dust bin for capturing dry debris during cleaning cycles
  • HEPA filter: a filter located in the dust bin that helps to capture fine particulates while cleaning
  • Cleaning tool: allows you to clean in the crevices of the vacuum to maintain optimal performance
  • User manual: provides information about the use and care of the Roborock S6

E3 & E2 Accessories

The Roborock e35 and Roborock e25 include all of the basic accessories listed above as well as the following mopping accessories:

  • Mopping reservoir: a thin tank for water to use when mopping
  • Mopping pad: these pads velco onto the bottom of the vacuum and helps to scrub the floor while its mopping
  • Water tank filter: helps to capture any dirt or debris that the mopping pad may miss during a mopping cycle
  • Moisture-proof mat: this mat goes under the charging station when mopping

S6, S5 Max, & S5 Accessories

The Roborock S6, Roborock S5 Max, and Roborock S5 comes with all of the accessories listed above as well as additional mopping pads and filters, as shown below.

Roborock Naming Explained

You will see a variety of confusing sub-models out in the wild. However, these aren’t as complex as they may seem.

Numbers that fall after the model series number indicate other features about the vacuum. Typically, the color.

For example, the Roborock E35 means it’s a Roborock E3. The 5 means it is the grey color.

Roborock E35 aka Roborock Xiaowa Plus
Roborock E35 aka Roborock Xiaowa Plus

These complex naming systems are more widely used in Roborock’s older robots, specifically the E3, E2, and C1. Roborock’s newer S4, S5, and S6 use a standard model name.

Are Xiaomi Mi and Roborock the Same?

No.

Roborock built the first generation Xiaomi Mi for Xiaomi. Presumably, they are building others for Xiaomi Mi as well.

However, Xiaomi Mi and Roborock are not the same company.

Xiaomi Mi does not own Roborock. However, Xiaomi is an investor in Roborock and they have a working relationship with each other, which is visible in their overlapping product names.

Roborock S6

The Roborock S6 is the most advanced model Roborock builds. It has all of the same features as the Roborock S5, but is 50% quieter and has a more advanced navigation system.

The S6 can run for up to 150 minutes and can clean up to 2,700 square feet.

It uses a 2-in-1 design that both vacuum and / or mop (same as the E2 and S5).

This vacuum used advanced ‘No Go’ lines in its digital mapping and is able to navigate and cleap up to 2100 SF. ft. during each cleaning cycle.

Many times, the Roborock S5 is incorrectly identified as the Xiaomi Mi 2nd generation robot. However, this is not correct. It is its own standalone model built and sold by Roborock.

Roborock S4

The Roborock S4 launched September 23, 2019. It’s designed to be a sweet spot between price and performance, sitting in between Roborock’s budget E model line up and the more expensive S5 and S6.

The S4 is able to clean spaces around 2,700 square feet.

Roborock’s S4 uses a new drive-train system that allows it to drive both forward and backward. This improvement allows it to more easily escape from obstructions and obstacles.

In our cleaning tests its performance was excellent, scoring an average of 96%.
