In short, the Roborock S4 is a cutting edge and smart robotic vacuum that can deal with your carpets’ loose debris and dander, getting rid of them from your home entirely. With the vacuums’ incredible suction power as well as a battery life that lasts, you get a perfect package when it comes to keeping your home thoroughly clean.

|Recharge & Resume||yes|
|Docking & Recharging||yes|
|Side Brushes||1 pcs|
First things first, let’s talk about how well this robot sucks. The S4 is able to deliver up to 2,000 Pa of suction pressure to pick up and remove small and large debris, including pet hair, from low- and medium-pile carpeting.
However, it does not have a self-adjusting system that automatically reduces or increases suction pressure based on the surface it’s cleaning so you’ll need to change gears, so to speak, manually to save battery power.
|Roborock S4 Cleaning|
|Suction Power||2000 Pa|
|Сleaning Area||2691 ft2|
|Dust Container||420 ml|
|Automated Dirt Disposal||no|
|Barrier-cross Height||0.59 in|
The way the S4 does its job, other than using 2,000 Pa of inward suction force, is by gently beating your floors and carpets with a set of three brushes. Its main weapon is a floating brush that self-adjusts in order to fully make contact with the floor.
The side brushes draw dust and debris into the machine where the suction inlet handles the rest. The most impressive thing about the side brushes is that they’re angled specifically to pull debris in rather than send them scattering across your floors.
150-minute Continuous Cleaning
Like many of other products in the Roborock S series, the S4 sports a large 5,200-mAh battery that powers the robot for up to 150 minutes nonstop.
Each charge provides enough power to have the robot travel up to 2,700 square feet before it makes a beeline straight for its charging dock. After approximately three hours of charging, the S4 will dismount from the dock and pick up exactly where it left off.

|Rated Power||58 W|
Great Navigation and Mapping
The S4 is equipped with advanced navigation software and mapping sensors scan its surroundings to compile a digital map of your home’s floors. It uses this map to create the most efficient cleaning path in order to make the most use out of its 150-minue runtime.
The robot does a pretty decent job at creating the map, although some areas of a room, specifically those blocked by furniture or other obstructions, may not be fully registered into the system. A second or third pass should help with scanning every vacuum-able square foot of your home.
Programmable Virtual No-Go Zones
Users have the option of controlling their S4 via the Roborock smartphone app. The app offers a ton of different programmable functions, including setting up virtual no-go zones where the robot cannot enter or pass through.
This is great for those with vases or pet bowls sprawled out on the floor and don’t want their robot knocking them over. The S4 is also compatible with Roborock virtual boundary strips which are used to create more precise barriers.

|IR Remote Control||no|
|Wi-Fi Frequency Bands||2.4 GHz|
Selective Room Cleaning Option
Not only can you tell the robot where it can’t go, but you tell it which room or rooms it should prioritize cleaning. The selective room cleaning option keeps the robot within the confines of one or more rooms where it will concentrate all of its battery power on cleaning.
Manual Steering with Pin & Go
Even though the Roborock S4 is equipped with highly advanced navigation software, it’s still far from perfect. The S4 may skip a few spots here or there, but the option to manually program a movement path using your smartphone should help clean any places it may have missed.
The Pin & Go function on the Roborock app lets you use your smartphone as a joystick to send the robot directly where you want it.

Not a Hybrid
Lastly, it’s important to note that the S4 is NOT a vacuum-mop combo bot. It does one thing only—vacuum (and sweep to an extent)—but it does it beautifully. The lack of a mopping feature is by no means a deal-breaker, though if you’re looking for a hybrid bot, may we suggest the Roborock S4 or E4?
