Roborock S50 Vs. S55 Verdict

To a large extent, the Roborock S50 and S55 are pretty similar in a lot of ways. Notwithstanding, there are a few significant points of differences and improvements, especially with the S55 that make it more functional and effective for cleaning than the S50.


The weight of a robotic definitely influences its operations. The Roborock S55 weighs only 7 pounds while the S50 weighs as much as 14 pounds plus! When using on a light carpet especially, you would notice that the Roborock S50 often pulls up the carpet rather than vacuum it. On the other hand, the Roborock S55 easily glides over your carpets, thereby giving you a superb cleaning outcome.

Smart Laser Navigation

If you’ve had an awkward experience with robotic vacuums, you would understand that most of them get stuck between furniture or cables around your home while vacuuming, and that’s not a very cool experience because it means you will have to manually pick them up when such happens.  It will interest you to know that there is never such an experience with the S50. You want to know the secret? Oh yes! It lies in its special laser navigation system which helps the robotic vacuum to notice obstacles around about a yard away, and expertly navigate around them. The Laser navigation system also helps your S50 to vacuum steeps and corners of your staircase without falling off. This makes it easier to schedule cleaning with the S50 even when you’re away at work or on a trip. You can trust the S50 to find its way around your home and return safely to dock.

What We Like
  • Suitable for pet cleaning as much as for use on multiple surface floors.
  • Highly computerized and therefore easy to use even for first-time users.
  • Its added bumper keeps it safe if it hits against walls and furniture while cleaning.
  • Produces a relatively low noise at only 55dB.
  • Its strong battery gives you ample runtime after full charge.
  • Its navigation system saves you the stress of having to manually pick the vac. It hardly gets stuck!
What We Don't Like
  • Quite too weighty for a robovac at 14.05 pounds.
  • Its 500ml dust tank doesn’t complement the battery life. This means you have to empty it a dew times if you’re doing some thorough vacuuming.
  • Just a 1year warranty. For many, that’s a huge turn-off.
  • A little expensive

Roborock S55 Review

Roborock S55

Till date, my S50 still serves me perfectly well. However, I needed to get a supplement for the other floor of my house since the S50 would not go from floor to floor. So I picked the S55, and I’m grateful I did! The S55 is a wonderful improvement on the S50. As a matter of fact, most of the features are similar but better especially in operation and ease of use. It has turned out that I love the S55 more because of its superb performance and other key features as follows:

Map Saver

It will amaze you to learn that this Roborock product can save the map of your apartment. From your mobile app control system, you can see and save the map of your home floor even as it cleans. This gives you a number of benefits. First, you can choose to select a portion of the map where you want your S55 not to clean. Say, for example, your kid has messed up his/her room, you could use the map to direct the Roborock to clean only that portion and it will do just that! Amazing, isn’t it? More so, if after the general vacuuming, you realize that there is a stubborn spot that wasn’t well cleaned, you could box that very region with your map using your mobile app, and the Roborock S55 will visit that same spot and focus on it.

Laser Distance Sensor Navigation

The LDS is an improved navigation system that comes with the Roborock S55. The navigation system helps it to move around completely at 360°, avoid obstacles and also to climb hassles as high as 2cm from the floor.

Improved Battery Capacity

Common to all Roborock product is the powerful Li-battery. The Roborock S55 has an improved battery lifespan and a capacity of 5200mAH that runs as long as 2 hours and thirty minutes for your nonstop cleaning.

Multiple Cleaning Accessories

Another outstanding feature that makes me fall in love with the S55 is that it comes with a number of cleaning components that makes vacuuming easier with or without supervision. A strainer, a washable mop cloth, water pad, barrier tapes, filters and several others are what you get when you procure a Roborock S55.

Clean and Mop Mode

The S55 holds this extra advantage over the S50. In addition to the available cleaning modes, it provides you with sweep and mop cleaning system. This means your robovac can first sweep your floor and at the same time give you a deep mopping.

HEPA Filter System

So many vacuum users avoid vacs without a strong HEPA filter, and that includes me. So if you’re looking for a robovac with a good filter system to keep dust down and keep away allergens, the Roborock S55 is perfect for you!
