Kyvol Cybovac E31 evaluate – Tech Advisor

Whilst you could be extra conversant in mother or father firm VanTop’s different wares – specifically its sprint cams and projectors, sub-brand Kyvol lately launched a trio of competitively-priced robotic vacuums – the most-capable of which is the Cybovac E31.

Highlights embody gyroscope-guided zig-zag cleansing for better accuracy and protection, as much as 2200pa of suction and, in contrast to the Cybovac E20 and Cybovac E30, which launched alongside it, mopping performance too.

Your cash not solely will get you the vacuum and a charging base but additionally a distant (AAA batteries included), a aspect brush (plus a alternative in-box), the water tank with a mopping fabric already fitted (plus a alternative fabric), a spare HEPA filter, a magnetic strip with adhesive pads and a cleansing brush. All in all a reasonably beneficiant assortment of extras come included for the value.

Design & construct

The E31 stands out from its launch siblings due to some blue accenting beneath the tempered glass of its round prime, which is a pleasant contact if you wish to pull a considerably odd flex. The remainder of the physique, in the meantime, is predominantly translucent black plastic – so might present put on and tear after bumping into issues after prolonged use; in testing, nevertheless, the E31’s seen exterior remained wanting virtually box-fresh the entire time.

This cylindrical vacuum measures 72mm excessive – equal to the likes of the Eufy RoboVac G10 Hybrid – which proved to be simply low sufficient for my slouch of a settee however ought to fortunately match underneath most furnishings (the place you’d anticipate a robotic vacuum to suit, a minimum of) with out subject.

The highest of the E31 options flush Residence and Clear/Pause buttons, which change color to point varied issues; like cost state, battery life and WiFi connectivity. The underside in the meantime is a swathe of matte black plastic affected by the varied fundamentals of the E31’s cleansing system.

All of the transferring elements are accented by vibrant orange plastic, together with the aspect brush, which clips onto the underside of the vacuum securely – so securely in-fact that though there is definitely no threat of it coming off throughout cleansing, it does increase a slight concern on the subject of alternative (Kyvol says the aspect brush needs to be changed each three to six months “or when it is visibly worn”) – a minimum of swapping this out is not prone to be a frequent prevalence for many.

There’s additionally the primary curler – which pops out simply sufficient, an omnidirectional castor, charging contacts, a protected energy swap and a pair of drive wheels with a powerful clearance vary; which you may discover if you decide the E31 off the bottom.

For the Cybovac to transition from vacuum to mop, all you want do is raise the orange latch on the 600ml dustbin (which comprises the HEPA filter), pull it out and change it with the included 300ml water tank, making certain the mop is fitted too.

The tank has a rubber seal to keep away from spills as soon as it is crammed however it’s greatest to not manipulate the E31 removed from horizontal whereas this reservoir is put in.

Cleansing efficiency

The default cleansing mode when utilizing it as a vacuum is ‘Auto’ – outlined by its medium suction stage (the E31 helps three ranges of suction) – and zig-zag cleansing sample.

It is the go-to possibility for on a regular basis cleansing and, positive sufficient, firing it up for the primary time it despatched the E31 zigging and zagging throughout the laminate flooring for my condo for an hour.

The pathing does appear considerably random and may favour sure areas whereas neglecting others. It pays to start out the vacuum off in a special location from time to time should you discover that it treads the identical floor too typically.

Even when the flooring seem comparatively clear to start with, the E31 is ready to fill its bin on a regular run. It overcame the lip of a very steep doorway threshold – transitioning from laminate to tile – with ease and resorted to its computerized carpet increase characteristic when tackling rugs and coir matting, which got here out surprisingly effectively afterwards.

Kyvol suggests that you just tidy a contact earlier than setting the E31 free – transferring the likes of wires (reminiscent of cellphone chargers) and tucking carpet tassels out of hurt’s means. In testing, I anticipated the bottom of a bunched-up curtain in my eating room to trigger it subject however it merely handled it like a boundary and moved on with out bother. Skinny objects – in my case, the legs of an ironing board – might show too slender for the vacuum’s sensors to select up each time – leading to an audible crunch as the 2 made contact – so take away what you may earlier than a cleansing session.

In case your E31 does find yourself getting caught, nevertheless, it will subject a loud beep and push an alert to your cellphone (should you’ve arrange the app, that’s), making it straightforward to retrieve and set proper.

There’s additionally the matter of drops and no-go zones. I haven’t got any steep or sudden drops in my dwelling however the E31 is provided to make sure it would not take a tumble down a staircase ought to it discover itself at any type of ledge.

The included magnetic strip could be reduce to size and secured with adhesive tabs should you do not wish to the vacuum venturing previous a sure level in a lot the identical trend as its drop sensor and sure-enough it really works as promised, each time; even when the strips themselves aren’t probably the most enticing addition to a room.

In case you’re conscious of specific hotspots for mess in your home, the E31’s Spot mode will rove outwards in a spiral (to about 1.2m) from wherever its start line is (and again in once more) over the course of a few minutes, with a purpose to pay additional consideration to any drawback areas. Edge mode is equally suited to paying extra consideration to the perimeters of rooms and round bigger gadgets of furnishings too – operating for 20 minutes at a time.

In addition to emptying out the mud bin after a clear, it is price utilizing the included cleansing brush to take away any fibres which will have wrapped themselves round any of the transferring elements on the underside of the E31. The detachable items make it straightforward to drag out any detritus, however it’s additionally price checking the drive wheels and castor too, simply in case.


As for mopping, altering setups is as straightforward as eradicating the mud bin and changing it with the water tank (as soon as crammed); ensuring the mop fabric is fitted too. You need not take away the aspect brush, as I initially assumed, so all that is truly required is a really fast and easy swap-out.

Equally to suction when utilizing it as a vacuum, you’ve got the choice to decide on the water output (from the app UI a minimum of) throughout three ranges, which you may should determine upon primarily based on the flooring you are having cleaned.

I had it set to stage two and stored the mopping to the tiled surfaces of my kitchen and toilet. It is truthful to say that this characteristic is nice for a floor stage clear however as a hybrid, the E31 lacks the grunt crucial to really scour powerful stains or get into the grouting between tiles with any actual fervor. It is nonetheless a pleasant inclusion, however its description in Kyvol’s advertising supplies as a “mopping helper” appear apt.

Connectivity & battery life

Whereas the included distant permits for simple operation of a lot of the Cybovac’s features, together with guide controls, cleansing modes and scheduling, it is Kyvol’s cell app that provides the richest expertise.

The app requires that you just make an account, which is not a very arduous course of, and as soon as signed in grants entry to all the performance of the bodily distant, together with a heap of extra knowledge.

From the app you may see the vacuum’s cost state, how lengthy it has been operating on its present cycle and even view the map that the E31 builds because it roves round your home – which can also be a great tool if you wish to know the place it’s mid-cycle and the way a lot square-footage it is lined.

By way of stats, you may as well see the state of replaceable elements underneath the ‘consumables’ part, for issues just like the aspect brush and cleansing fabric, in addition to the choice to call Cybovac. “Why would you wish to identify the vaccum?” you may ask; as a result of the app can also be the place you may pull in Google Assistant or Amazon Alexa voice management.

Whereas that is solely actually good for beginning and stopping the E31, it does really feel decidedly Jetsons telling your robotic vacuum to take a flip about the home.

Battery life

As for longevity, the E31 takes between 6 and 6.5 hours to completely cost, which guarantees as much as 150 minutes of cleansing time. In fact, mileage will range relying on elements like flooring floor, suction stage, sq. footage lined and so forth.

In an hour-long auto session, with suction stage two, protecting roughly 55m² throughout laminate, tile and a set of rugs and coir matting, the Cybovac returned to its charging station with 53% cost left in its cells.

Cost stage is seen on the highest of the E31 primarily based on the color of the ability button backlighting. Blue means loads of cost, orange means they’re beginning to run out and flashing pink is vital.

Value & availability

You possibly can decide up the Cybovac E31 direct from Kyvol within the US, Germany or Japan, priced at US$279/€299.99/¥27,999 or decide it up on Amazon in different markets, together with the UK for £279.99.


The E31 is probably not as highly effective as dearer options, just like the Ecovacs Deebot Ozmo 920 or the Roborock S6 Max V, however for the value, you are getting a succesful machine that does not want nannying and packs a powerful feature-set, backed up by a strong app expertise.
