Any hyperlinks to on-line shops must be assumed to be associates. The corporate or PR company offers all or most evaluate samples. They don’t have any management over my content material, and I present my sincere opinion.
I discover the robotic vacuum/mop trade fairly attention-grabbing. It jogs my memory of the early days of cellphones, after we noticed important enhancements within the know-how over a brief time frame, which has made writing about them extra attention-grabbing than different niches like telephones with barely incremental enhancements every technology.
Whereas iRobot Rooma launched a few years in the past again in 2002, it took some time for the market to warmth up and inexpensive choices to come back to market.
The Eufy RoboVac 11 was certainly one of my first robotic vacuum evaluations again in 2018, which was a fundamental robotic vacuum with no mapping that might bounce across the partitions of my kitchen.
Lidar and VSLAM mapping revolutionised every part, permitting robots to intelligently map your private home. Then got here auto-empty stations to cut back upkeep.
Many early fashions had mopping, nevertheless it was very fundamental gravity-fed addons, which I personally by no means used on the common. Prior to now few years, all-in-one stations with water tanks have taken off automating the entire mopping course of.
Final yr, SwitchBot was the primary firm to launch a robotic vacuum and mop that had an auto-fill and empty station that was plumbed into your water mains, permitting it to be nearly utterly maintenance-free for mopping.
Now, they’ve launched its successor, the S20.
Sadly, I don’t actually have wherever the place I may join the mop station to my plumbing, so I needed to go for the extra conventional all-in-one base station with water tanks.
And with a worth of £800, it has launched at a a lot lower cost level than the older mannequin.

RinseSync Expertise: Self-Cleansing Whereas Mopping
The standout function here’s what SwitchBot calls “RinseSync” – a four-step course of that cleans the mop while it’s nonetheless working. The system wets, scrubs, squeezes, and drains the mop at 300 cycles per minute, making use of 1kg of downward strain. It’s an attention-grabbing strategy that ought to theoretically forestall you from simply spreading soiled water round your flooring.
I’ve examined sufficient robotic mops to know that almost all simply drag dirty pads throughout your surfaces, so if this really works as marketed, it may very well be fairly helpful. The proof can be in real-world testing, notably on closely dirty areas.
Navigation and Impediment Avoidance
The S20 combines LiDAR SLAM with Place Delicate Detector (PSD) know-how and an AI digicam system that reportedly recognises over 100 impediment varieties. It might probably climb thresholds as much as 20mm excessive and consists of an computerized gentle for darkish environments.
The multi-sensor strategy is smart – pure LiDAR struggles with clear objects and low-lying obstacles, while camera-only methods can fail in poor lighting. Whether or not the AI impediment recognition is genuinely helpful or simply advertising and marketing fluff stays to be seen.
Cleansing Efficiency Specs
Suction energy hits 10,000Pa, which matches some premium fashions. The twin anti-tangle system features a V-shaped facet brush and rubber primary brush – each designed to cut back hair tangling, a perpetual drawback with robotic vacuums in properties with pets or long-haired occupants.
Battery life varies considerably relying on mode: 250 minutes in quiet vacuum-only mode down to simply 70 minutes on most energy with mopping. These figures appear practical primarily based on the 4,000mAh battery capability.
Base Station Capabilities
Two base station choices can be found. The usual model consists of 2.7L clear water and a couple of.5L waste water tanks, while the premium mannequin connects on to your private home’s water provide for computerized refilling and drainage.
The bottom station offers 50°C scorching air drying with 360-degree airflow – necessary for stopping mould and odours in damp mop supplies. Mud disposal is rated for 90 days of hands-free operation with a 4L capability bag.
Flooring Sort Adaptability
The S20 mechanically adjusts behaviour primarily based on ground sort. On carpets, it lifts the mop 7mm and features a wiper to take away extra moisture, while concurrently boosting suction to the complete 10,000Pa for deeper cleansing.
For arduous flooring, the system applies measured water move and strain for efficient mopping with out oversaturation. The carpet detection makes use of present sensing somewhat than optical strategies, which must be extra dependable.
Sensible Dwelling Integration
Matter 1.4 assist is promised for late August or early September 2025, which ought to present broad compatibility throughout sensible residence platforms. Apple Dwelling customers get part cleansing performance, while the system additionally works with Google Dwelling, Alexa, and the broader SwitchBot ecosystem.
The power to customize cleansing plans for various areas and ground varieties via the app may show helpful for properties with combined flooring supplies.
Bodily Specs and Practicalities
At 365 x 365 x 115mm, the S20 is pretty customary sized for a premium robotic vacuum. The bottom station measures 380 x 223 x 460mm for the water tank model, so that you’ll want first rate storage space or a utility space for set up.
Noise ranges vary from 60dB in quiet mode to 69dB at most energy – corresponding to most high quality robotic vacuums. The <4 hour charging time is cheap for the battery capability.
Unboxing / Design
The SwitchBot S20 has an identical design to most robotic vacuums with its function set.
The robotic itself is a typical design, you may have the LiDAR module on high with the VSLAM cameras and LED lights on the entrance.
There’s a detachable cowl which exposes the ability swap and the small dustbin. Then on the bottom you may have the curler mop, the primary vacuum curler and a facet sweeping brush.
As I opted for the extra typical water tank mannequin, the all-in-one station is kind of giant with compartments for clear and soiled water. Beneath these is the compartment for the mud, and to the facet of it is a small cubby gap containing a bottle of floor cleaner for use with the mop.
One factor I observed in my reviewer’s information was that each S20 fashions are appropriate with the older S10 water station. This may very well be helpful if you’re upgrading.
Set Up
Organising the S20 is comparatively easy. Obtain the SwitchBot app, join the bottom station and robotic by way of WiFi and Bluetooth, and comply with the in-app prompts. It’s right here that SwitchBot’s rising give attention to ecosystem ties in – if you have already got their humidifiers, curtain openers, or sensors, every part hyperlinks collectively.
The bottom station requires a agency, stage floor with at the very least 0.5m clearance on either side and 1m in entrance. For the plumbed model, you’ll want entry to water provide and drainage connections, although set up movies can be found via QR codes within the guide.
Preliminary charging takes round 4 hours, after which the robotic mechanically begins its first mapping run. The method is methodical and takes about an hour for a typical residence, creating an in depth ground plan that types the premise for all future cleansing routines.
SwitchBot App Interface and Settings
The SwitchBot app offers complete management over the S20’s capabilities. The principle interface shows a real-time map of your private home with cleansing progress, battery standing, and present mode clearly seen.
Room identification works nicely, mechanically detecting and labelling completely different areas like “Kitchen,” “Residing Room,” and “Bed room.” You possibly can rename rooms, merge or cut up areas, and set digital no-go zones with easy finger gestures.
Cleansing customisation is in depth. Every room can have its personal suction energy stage, water move fee, and cleansing sample. You possibly can schedule completely different routines for various instances – maybe a fast vacuum within the morning and a full vacuum-and-mop session within the night.
The app additionally offers detailed cleansing stories, displaying protection maps, time spent, space cleaned, and any obstacles encountered. This information helps you optimise cleansing schedules and establish drawback areas.
Matter & Dwelling Assistant
This robotic options Matter 1.4 and may be built-in with third-party ecosystems comparable to Dwelling Assistant, Google Dwelling and Amazon Alexa.
Sadly, on the time of writing, this had not been enabled but. I used to be ready so as to add the S20 to the SwitchBot Hub 3 and this lets you have some management of the robotic vacuum from the hub, nevertheless it doesn’t at the moment expose the S20 to Matter, and due to this fact Dwelling Assistant.
Moreover, I attempted the native SwtichBot Dwelling Assistant integration to see if that might make a distinction, however the S20 was nonetheless not accessible in HA.
I anticipate this can be enabled quickly, and anticipate it to perform a bit just like the Yeedi S16 Plus, the place there’s restricted performance. Although, it is going to be attention-grabbing if this has extra choices for triggers/actions to can help you create some automations.
Mapping Efficiency
The mapping efficiency has been glorious, which can be true for all of the current robotic vacuums I’ve reviewed not too long ago. That is primarily because of the mixture of LiDAR and vision-based mapping.
The robotic can apparently establish over 100 forms of obstacles and has a built-in LED gentle for darkish rooms.
When the robotic completes a clear, you’ll be able to look into the logs and consider which objects it has recognized.
Within the month I used the S20, there was just one incident when the comb received tangled and I needed to intervene. Contemplating I’m fairly messy and continuously have wires mendacity round on the ground, that is fairly spectacular.
The multi-floor mapping functionality works as anticipated, storing as much as 5 completely different ground plans. Shifting between flooring requires manually carrying the robotic, nevertheless it shortly recognises its location and resumes acceptable cleansing patterns.
Mopping & Auto Refill / Empty Efficiency
The RinseSync mop system represents the S20’s primary promoting level, and after in depth testing, it largely delivers on its guarantees. The curler mop repeatedly self-cleans throughout operation, stopping the cross-contamination points that plague conventional pad-based methods.
Throughout mopping, you’ll be able to really hear the system working – each few seconds, there’s a quick mechanical noise because the mop undergoes its four-step cleansing cycle. Initially regarding, this sound turns into reassuring when you perceive it signifies lively self-maintenance.
The 1kg downward strain offers efficient scrubbing motion on sealed arduous flooring. Sticky spills that might usually require guide pre-treatment got here up fairly nicely, although closely caked-on grime nonetheless advantages from conventional mopping first.
Water utilization is conservative however efficient. The two.7L clear water tank usually lasted for about three full-house cleansing classes in my 60m² floor ground earlier than requiring refill. The waste water tank crammed proportionally, although the collected liquid was noticeably darker than enter water – proof that the system really removes grime somewhat than simply redistributing it.
The recent air drying system works nicely, utterly drying the mop inside 2-3 hours after cleansing. This prevents the musty odours that usually develop with damp mop supplies. The adjustable drying length (1-8 hours) accommodates completely different climates and utilization patterns.
One limitation: the cleansing answer have to be SwitchBot’s proprietary system. Third-party options might injury the interior pumping system, in line with the guide. Every 150ml bottle offers roughly 10-15 cleansing classes, including to working prices.
Vacuuming Efficiency
I didn’t evaluate the older S10, however the S20 has had the suction energy elevated from 6500Pa to 10000Pa, which ought to give it significantly better efficiency. That could be a little bit behind the Dreame L40 Extremely (11K )and far decrease than the Yeedi M14 Plus (18k) and Yeedi S16 Plus (16.6K)
Actual-world efficiency largely matches the specs. On arduous flooring, the ten,000Pa suction simply handles each day particles – crumbs, mud, pet hair, and small particles disappear with out a number of passes. The rubber brush design does scale back hair tangling considerably in comparison with bristle options.
Carpet efficiency varies by pile peak and density. Low-pile rugs and mats clear completely, with the automated suction increase offering noticeably higher outcomes than customary energy. Nevertheless, deep-pile carpets nonetheless problem the system – embedded particles requires a number of passes or guide pre-vacuuming.
The anti-tangle facet brush design works as marketed. Throughout testing, I intentionally scattered hair ties and free threads across the ground. The V-shaped design efficiently flung most tangles clear, although occasional intervention was nonetheless required for notably problematic objects.
Edge cleansing efficiency is sufficient however not distinctive. The facet brush reaches into corners and alongside baseboards fairly nicely, although guide touch-ups are generally wanted for cussed accrued grime.
Battery Life
The robotic vacuum has a 4000mAh battery and claims a run time of 150 minutes in quiet mode, 130 minutes in customary, 100 minutes in robust and 70 minutes in max mode.
I’ve been utilizing it within the default mode, and it usually stories the cleaned space as being 48 to 50m2 with a clear time persistently round 1 hour. So, the battery life has by no means been a difficulty, and even when I had an enormous home, robotic vacuums will return to base for a cost, then head again out to finish a clear.
Value and Various Choices
Whereas the embargo for this evaluate has solely simply lifted, the SwitchBot S20 has been on Amazon for a few months.
The model I reviewed with out the plumbing mains connection has an RRP of £800, and on the time of writing (30th of August), it was accessible for simply £600.
The Autofill & Drain System model has the identical RRP however just isn’t on Amazon but, and there are at the moment no reductions.

Competing choices embody:
- Roborock Qrevo Curv, which is on the market for £800, discounted from £1300. That is nicely reviewed, nevertheless it makes use of mop pads somewhat than a curler, which I discover to be inferior.
- Roborock Qrevo is on the market for £430 with an RRP of £700. Just like the above however decrease spec general.
- Eufy Omni C20 is on the market for £430 with an RRP of £600. Just like the above, however decrease spec once more. Properly reviewed
- Eufy E25 Omni is on the market for £800 with an RRP of £800. That is extra superior than the others with an extending sweeping arm and a curler mop. It has a really excessive suction energy.
- Eufy E28 Omni, which has an RRP of £999 and no present reductions. That is just like the above, however the water tank is removable and can be utilized as a transportable deep cleaner for spills.
- Dreame X50 Extremely has an RRP of £1200 and is on the market for £1000. This has a novel potential to climb steep 6cm thresholds. It makes use of mop pads however has the benefit of with the ability to prolong the mop out to get into crevices, in addition to a twin brush system for higher cleansing.
- Dreame L50 Professional Extremely is on the market for £850 with an RRP of £900 and can be utilized with mains water or simply the self-contained water tanks.
General
The water tank model of the SwitchBot S20 is a strong robotic vacuum with all of the options most individuals would possible need, and it comes at a aggressive worth level.
Probably not a criticism, however there are loads of related merchandise available on the market at good worth factors, so it maybe doesn’t stand out from the group apart from having Matter assist in some unspecified time in the future sooner or later.
If you have already got SwitchBot merchandise, then that is a straightforward advice, as I discover it finest to maintain as many merchandise underneath one ecosystem as doable.
Whereas I haven’t used it myself, the auto-fill and drain mannequin is a way more interesting mannequin because it has only a few competing choices and it’s extra inexpensive than the choices from different manufacturers.
The RinseSync know-how works as marketed, offering genuinely cleaner flooring in comparison with fundamental mop methods. Mixed with strong construct high quality and complete app management, the S20 represents good worth at present pricing.
