I’ve never been a person who prioritized cleaning the floors. I love a clean house, but I can never find the time to do it. So a few years ago, when I decided to start reviewing robot vacuums, I knew my cleaning prayers were answered. I’ve recently been able to test out some new models of robot vacuums, and the Roborock S4 Max is one of them. I had a chance to have one running in my home for about 4 weeks to test it out .

What is Roborock S4 Max?
This bot is a straight up robot vacuum, controlled by a smartphone app. While some models can double as mops, this is not one of them, but that’s okay. This robot, just like some other much more expensive models has laser guided navigation and smart mapping built in, which we’ll get to.

What’s the difference between Roborock S4 and S4 max?

The S4 Max is the premium vacuum from Roborock. This version has advanced Multi-level mapping that lets you use it on up to 4 different floors or storeys of the home, it has Automatic Carpet Boost to power dirt out of carpet fibres, a slightly longer cleaning time/battery life so it can clean larger spaces on a single charge. The dustbin is also slightly larger on the S4 Max (S4 Max Dustbin = 460ml; S4 Dustbin = 420ml) and it has a slightly higher threshold climbing capacity, meaning it can get over bigger bumps and humps than other vacuums.

What you get with Roborock S4 Max

In the box you get the botvac and its compact charging base.

Let’s take a quick tour of your bot; it’s got roller brushes underneath and a corner brush. The bot has big 4x4 style wheels to help it get around challenging spaces and on the other side under the hood, is the dustbin.

Laser LiDar navigation: Roborock

So what does Lidar do? This lets the bot ‘see’ around obstacles and in bouncing its lasers off the walls and furniture it can draw a really detailed map of your home; then it knows where it can and can’t go, it knows which obstacles to avoid, and you can delineate specific rooms for dedicated room by room vacuuming. The laser map guidance also means the bot doesn’t slam into table legs and walls at top speed, so it treats your stuff a bit more gently.

After just one pass, my bot had a viewable map, and that’s significantly faster than some other pricier bots. Also, unlike a lot of other bots, the Roborock S4 is ready for you to label and customize your home map for room-specific cleaning right from the get-go (other bots need days or weeks of repeated passes to create the map).

Roborock says it’s hard to trap: true

Roborock makes a point on its website of saying the S4 is “hard to trap” and that it’s “engineered to escape the areas where others would get stuck.” I can say I found this to be true during my testing; I was also reviewing another very similar botvac at the same time and that bot would get stuck constantly, while the RoboRock S4 was able to give me a thorough clean, and return to base without incident. I never saw it get stuck once.

In terms of its ability to get over taller obstacles, I can say that’s true also; it was never hung up on trim, edges or rugs while that other bot was.

I can confidently say that of all the robot vacuums I’ve ever tested, this one probably got stuck the least; it needed almost zero rescuing or help from me.

Suction power on carpet

Roborock says the S4 is “built for a Deeper Clean, with Intense suction, able to lift AA batteries, easily lifts dust off floors and pulls it out from inside carpets.” Powerful HyperForce™ suction creates up to 2000Pa1 of suction power, pulling dirt and pet hair off wooden floors as easily as it dredges it up out of carpets. Ideal for picking up after messy kids and hairy pets.

That’s the marketing pitch, but I can say I was quite impressed with how well the Roborock S4 was able to clean the carpets and rugs in the house.

When I emptied out the dustbin I noticed it picked up everything from very fine dust to bigger debris, pet hair to pieces of plastic.

Noise level

Of course, folks always want to know how noisy these bots are. I’d say the Roborock S4 Max is about average when it comes to noise levels, and maybe a touch quieter than that. It does make a noticeable boost in noise when it hits carpets, but it’s not deafening.

Overall review RoboRock S4

Overall I can’t tell you how happy I’ve been with this botvac. Having never tried Roborock before, I wasn’t sure what to expect, but I was blown away by the premium features, the deep clean and the ultra-easy to use app. I can definitely recommend it if you’re looking for a robot vacuum.

Available from Amazon’s US store, the Roborock doesn't appear to be shipping to Canada right now, but I hope it will be soon because I really like it and think my Canadian friends would as well!
