Roborock has been making respectable robotic vacuums cleaners for a while now, producing the whole lot from the budget-friendly Q5 Professional, to the compact Qrevo Slim. All of which feels prefer it’s been constructing as much as its new flagship mannequin: the Roborock Saros 20 robotic vacuum and mop.
Just like the Qrevo Slim, this mannequin options voice management, and its look isn’t wildly completely different both. Nonetheless, it’s extra able to offering a high-quality clear, dealing with carpet and thresholds by elevating itself up, and recognising objects, together with wires, furnishings and even cat litter containers.
The mopping is extra superior too – not solely does it use detergent, it might detach and reattach its mop pads for vacuuming solely. This, plus an all-singing, all-dancing dock, makes it nice for busy households on the lookout for a greater than fundamental clear.
Design & Construct
- Can climb as much as 8.8cm
- Dock solely wants emptying each two months
- Cleans with sizzling water
Given the quantity of tech within the Roborock Saros 20 robotic vacuum and mop, you may count on it to be chunky, however removed from it. As a substitute, it’s a mean dimension at H7.98 x W35 x D35.3cm, though heavier than some at over 5kg. Its dimension means it might get beneath and round most furnishings with ease. Beneath, it’s geared up for an intensive clear with a sweeping aspect brush, two rubber rollers to forestall hair tangles, and a pair of extending arms that assist the robotic to climb as much as 8.8cm.

On prime, two buttons deal with the fundamentals, similar to sending it again to the dock or persevering with cleansing if it’s been stopped. You’ll be able to accomplish much more with voice management. As soon as it’s been arrange within the app, saying ‘Hey Rocky’ lets you instruct it do quite a lot of duties with out reaching on your machine and even involving a wise speaker (though it’s suitable with Alexa, Siri, and Google Residence). There are such a lot of potential instructions {that a} card itemizing them is provided.
The dock handles the enterprise finish of issues: it’s right here the place the robotic vac empties itself right into a bag (which can solely want altering each 65 days), refills with water and detergent for mopping, cleans (at 100°C) and dries its two mop pads (at 55°C), detaches and reattaches them, and prices.

For all that, it’s additionally fairly compact: solely H48.8 x W38.1cm, though a depth of 47.5cm, with further clearance required in entrance could imply it’s in the way in which in smaller rooms. You’ll additionally must preserve each the highest (for including clear water and eradicating soiled) and entrance (for topping up detergent and altering vacuum luggage) accessible.
Efficiency & Options
- Easy, superior mapping
- Scheduling was extra difficult
- Efficient cleansing
Organising a robotic vacuum will be time-consuming however Roborock’s Saros 20 was one of many quickest we’ve encountered. It related to Wi-Fi first time, mapped three areas in lower than two minutes (courtesy of a navigation system referred to as Clever StarSight System 2.0), and as soon as completed, it was simple to divide, merge and rename rooms through the app. The one actual situation initially was the place to place the dock – its energy cable is 110cm, that means that you just’ll want a socket shut by.
It’s easy to change the map when you’re up and working by including no-go areas and invisible partitions – we preferred which you can zoom into the ground map to do that, that means {that a} small machine display isn’t any barrier to personalising.
Different intelligent options embrace having the ability to change ground varieties in the event that they’ve been incorrectly recognised (similar to swapping tile for wooden), inform it to disregard obstacles in the event that they’re momentary (it’ll establish greater than 300 differing types, together with a ball of paper or a pet), and the flexibility to {photograph} obstacles in color – though for these involved about privateness, this may be turned off. There’s a light-weight too, for illuminating filth in darker areas, and the battery lasted effectively even throughout deeper cleansing cycles.

What’s much less easy is selecting schedules for cleansing. Not solely is that this characteristic hidden beneath common settings, it’s not as user-friendly as the remaining. There’s no information to utilizing it within the directions, but it provides quite a lot of choices, from a mysterious sensible mode to fully customized. I used to be in a position to set it to tug newly wetted, static mop pads throughout carpet whereas solely vacuuming, which shouldn’t be potential.
One other situation was that the default for scheduled cleansing is as soon as, which is odd on condition that schedules are normally meant to recur. Schedules which have run as soon as then disappear, so forgetting to pick out every day means setting the whole lot once more. I felt this ought to be easier for individuals who need to set and overlook. The presets for ‘routines’ have been extra helpful, and embrace actions similar to ‘after meal’ cleansing for kitchen and eating areas.
Frustrations of the app apart, what the Saros 20 does brilliantly is clear each exhausting flooring and carpet. Utilizing flour to symbolize advantageous mud and oats as bigger particles, pick-up was thorough on exhausting flooring. Solely somewhat flour grew to become trapped within the wheel treads, then dropped again onto the ground because it returned to the dock.
On a mid-pile carpet, all of the oats have been picked up. Some flour grew to become embedded, with essentially the most intensive suction unable to raise it, however we felt this was minor in comparison with different fashions. Once more, some floury tread marks have been left behind. However I particularly preferred the spot cleansing characteristic for going over dirtier areas once more – it may be activated both by holding the house button or saying, “Clear right here”.
On exhausting flooring, the mop efficiency was higher than most rivals because the pads can pivot outwards to scrub into corners and awkward areas. Nonetheless, we famous that the mopping was higher for little-and-often cleansing slightly than built-up filth. Utilizing dried-on sticky sauce, the primary mop clear lifted a few of it, whereas spreading the remaining round. Nonetheless, we have been in a position to return the robotic vac to the dock to scrub the pads and have one other go at it on the deepest clear setting. This time, all of the seen mess was eliminated. Nonetheless, as soon as dried, some stickiness remained and needed to be cleaned manually.
Whereas impediment recognition and talent to free itself when caught is extra superior than many, the Saros 20 isn’t good. Cat toys have been ceaselessly sucked up and their strings wrapped across the rollers. We needed to block off a hearth fireplace with a no-go space on the map as it could attempt to climb it and turn into caught. It even knocked off a mop pad throughout one cycle. Unfastened trim threads have been ripped off a curtain and wound round its rollers so it stopped mid-clean.
It will recurrently climb a doormat, then drag it alongside behind. The robotic additionally grew to become caught between a stool and a chair, a settee and a scratching submit, and generally on piano pedals. To its credit score, although, it recognised and prevented pets, a scrunched-up ball of paper, cat tree, wires, bigger furnishings, an extension lead and litter tray.

Must you purchase the Roborock Saros 20?
There’s no denying that the Roborock Saros 20 is an enormous step in the best path for a mopping robotic vacuum. It’s extremely simple to arrange, the know-how for recognizing objects and figuring out what they’re is spectacular (even when smaller objects tend to be missed), and voice management is a boon to these eager to minimise machine utilization.
Nonetheless, all this know-how is costly, whereas fundamental scheduling has been made extra advanced than it must be. These elements apart, in the event you’re prepared to place in time initially adjusting boundaries, drawing on a number of no-go areas, and retaining it away from chewable objects, it might ship an incredible clear with little or no want so that you can step in.
