My S20 will just ignore barriers like this.

Had this thing for around a year when i got it it was the cheapest robot vacuum with lidar.after a year here's what i think of IT: It vacuums supriseingly well actually i keep it on medium power because i don't really see a diference betwen medium and turbo power.the mopping thoung isn't briliant it does get very light Dirt of but it doesn't clean dried on stains even with the max Water setting.but its very good for daily maintanance cleaning.i have it set on a schedual so it cleans every day at 10:30 in the morning,and over this 1 Year period nothing has gone bad, it îs still on its original consumabiles I switch the mop every 2 Days with a other mop. The only minor issue is that now when it turns on the lidar sensor makes a teriable almolst tractor like sound when the lidar spins up,in rest there is only minor cosmetic damage,it does get stuck by closing the door to the bathroom by itself. But in my opinion it îs a very good product for the price and i Highly recomand it

I’d actually recommend OP get the S20. It’s just a little bit more but can be had for $400 and has dual brushes + mopping

Obstacle avoidance and navigation will basically be the same. Both use lidar and structured light. I’d go for the S20 for a vacuum focused robot. Y shaped cleaning patterns are pretty good at removing dust from floor crevices which is something the S40C cannot do.

Thats one of the best from Xiaomi line. I have an S20 and its been great so far. Nothing better when you can have someone else do the vacuum and mopping of your floors. Love it.

I just bought the Xiaomi s20+ without self emptying and after three days the bin was quite full even though my 1C vacuumed daily. I suspect it could be the higher vacuum power on the s20+. Makes think the self emptying might have been a good idea but it would have gotten clogged due to our amount of hair. In Malaysia, the S40C launched and I'm upset since I bought the s20+ last week. 🫤

I think the Xiaomi s20 without the + is sufficient if you don't need to mop. I got the s20+ with the rotary mops that I haven't used yet and the maps on 1c was good enough so the s20 will be sufficient. Plus it is compact sized. My s20+ battery only uses 1 bar to cover a large amount of space. So I think the s20 is sufficient. Get the s20.

This is why I am hesitating on the roborock q10 pf in my country. It is the q10 x5 in US. Will the spare parts be found in 3 years? Only if sales are good enough. The spare parts if too different may not be found so easily. Like the Dreame D20 (only with charging dock) in my country that is not the Dreame D20 Ultra in any way. And so far I have been unable to find the spare parts or know its equivalent elsewhere. For my Xiaomi 1C, I have managed to find parts to it. I have sent it in to get the wheels switched out under warranty, I have changed the filters and brushes at economical prices and I have switched out the batteries twice so far. The new ones are larger capacity but cause the robot vac to be a bit haywire. Perhaps I need to service the front wheel and clean the sensors? Either way, I am undecided between the roborock q10 PF and Xiaomi S20 or S20+. The S20 seems to fit my needs as a basic vacuum and is more compact allowing it to get into slightly tight areas but feels like just a little upgrade over my 1C that still works albeit haywire sometimes. It gets fixated on areas some times. I have put furniture risers ro accommodate the LiDar puck as that was the only hindrance on the new vacuums.

Xiaomi S20… Fantástico até agora. 1 mês de uso e não sei como ele junta tanto pó cada vez que despejo o reservatório. Antes aspirava 1 a 2 vezes por semana com o aspirador normal.

I got my xiaomi s20 for less than 100eur during black Friday I really love it. Of course it doesn't replace the cleaning, but I don't have to make it as often. Keep in mind the maintenance and the consumables
