It’s black and round, with two side spinning brushes to funnel dirt into its path to be sucked up. At the top you have a button to begin cleaning, return to the dock, or do a spot clean.

Right in the middle is a laser-guided system that allows the Cybovac S31 to both map out its space as well as navigate around intelligently. Other sensors including a fall sensor ensures that the vacuum doesn’t land up in tricky situations or get stuck anywhere.

Accessories included

Also included with the Cybovac S31 is the mopping attachment, which comes with both disposable and washable mopping pads, and a water tank that can be attached to the underside of the unit. There’s even a remote control if you prefer to manually control the unit, but this can also be done via the app.

The other part of the Cybovac S31 that’s important is its docking station. This performs two tasks – it serves as a charging base for the robot itself, but also houses a dust bag that automatically sucks all dirt and dust from the robot’s dust bin. The bag can hold up to 60 days worth’ of dust, and all you have to do is slide the bag out and throw it directly in the trash.


The S31 has a 4.3L self-emptying dustbin that can hold up to about 60 days’ worth of dust before you need to replace the disposable dustbag inside it. The dustbin doubles as the robot’s charging dock, providing about four hours of runtime per full charge.


The robot itself is powerful with a 3000Pa suction motor, which is the most powerful motor I have ever tried. It is quiet, too, at approximately 45 decibels so is hardly noticeable in use.

The Cybovac S31 features 3,000Pa of suction, which is great for picking up dust and dirt that’s tucked away between tiles or buried in a carpet. It’s great at picking up dust, hair, crumbs, and you can adjust the suction power of the vacuum on the fly. It also includes a ‘Boost’ mode that increases suction automatically when carpet is detected, but unfortunately we didn’t have much luck.


The robot itself navigates using Laser Distance Sensors housed in a turret on its top. During its first run through the room it, it creates a map of the floorplan that allows you to create virtual walls, cleaning areas, and no-go zones. The dirty business is handled by a rolling brush and two spinning side brushes on the bottom.


Mopping is another feature that you can enjoy with the Cybovac S31, but don’t expect results as good as going to town with a normal mop and some elbow grease. The vacuum drags a damp pad across your floor to pick up light stains, but because there’s no actual rubbing action, heavier stains will need to be cleaned manually anyway. You can of course set up no-go zones such as avoiding carpets before you begin mopping, so if you’ve got fairly clean floors and want to just have a very light mop, then the Cybovac S31 will do an adequate job.

Kyvol S31 Setup

With its dustbin-dock plugged in and the robot on its charging pins, I added the S31 and successfully connected it to my Wi-Fi. After that, I was prompted to download a firmware update; but each time I tried, I got a message saying the firmware couldn’t be upgraded until the battery was charged to more than 20 percent. I left the vacuum to charge for a couple more hours, but still got the same message when I tried to upgrade.

Kyvol app

The Kyvol app is well laid out, with extensive options to customize how your vacuum behaves. You can easily look at past cleaning cycles, adjust the volume of prompts, and set up no-clean zones. It’s also where you can set up cleaning schedules, so the Cybovac S31 can clean your space when you’re not at home.

One feature the Cybovac S31 has is the ability to store different maps, so you could store the map of both the downstairs and upstairs of your villa if you like. However in practice, this isn’t as straightforward to achieve or execute.

Kyvol S31 Performance reviews

The Cybovac S31 can vacuum and mop at the same time, so I attached the mopping module to the bottom of the robot for the entryway, kitchen, and bathroom. It holds 110ml of water and distributes it to the attached microfiber cloth as it drags along the floor. It doesn’t make enough contact with the floor—and provides no back-and-forth agitation—to remove anything more than surface grime. It’s adequate for semi-regular maintenance cleaning, but it won’t eliminate the need for your stick mop.

Spot cleaning is useful if you just quickly want to clean a small area, and the Cybovac S31 can clean approximately 2 square meters in this mode. It maps out the area into a square, and then proceeds to go over it twice, just to make sure it’s being thoroughly cleaned, which is a good thing.

Once a map has been created, the vacuum cleans in a much more predictable and efficient pattern. Setting cleaning areas is as simple as tapping a button in the app and dragging a resizable box to a spot on the map. There’s a similar process for adding virtual walls and no-vacuum and no-cleaning zones. The last was particularly helpful as my hardwood entryway abuts my carpeted living room; making the living room a no-mop zone ensured I didn’t end up with a soggy rug.
