"can be had for $400"
"For the price, I think it worth every penny."
"I absolutely do not regret buying the robot vacuum. ... My room is a lot cleaner and dust-free now, and I can tell just by wiping my floor with a wet toilet paper and seeing barely anything picked up. ... I've been getting allergens a ton less, most of which not even in my room. ... All this for the commitment of a weekly emptying is miles more convenient than vacuuming traditionally, as opposed to making a few taps on my phone. ... looking back it was definitely worth the investment."

"Yes, it does a great job vacuuming and climbing carpets. It worked on a traditional carpet and a faux fur carpet with no issue getting stuck. ... It also works great under tight spaces, such as my drawers and sofa, as long as it can fit (Maybe look up a manual and check for its dimensions)."

"Additional plus for this model is that it has option for professional mopping, and it does wonders. It actually cleans very well."
"Arguably the only truly quiet function, you can also pick how much water it dispenses in three levels."

"die Sperrzonen funktionieren perfekt"
"You can create virtual walls within the map, set a no vacuum&mop area, and a no-mop area. ... I also used the no vacuum&mop in places with a lot of wires."
"Die Karte ist super präzise"

"Every now and then I find it stuck and it's because it tried to suck up wires 90% of the time or climb up my floor lamp's base. ... The no-zone might not solve this because it's not very precise for small areas. ... Also If you have long curtains that drape to the floor, set it as a no-go zone for sure."
"It has a sensor but is still pretty clumsy and will bump into things along its way. ... This could damage or chip objects in the long run. ... It also always runs over my flips-flops and other small objects, so I always get them out of the way before starting it."

"The brush that spins around will sometimes get caught onto something and detaches so easily. ... Next thing I know I'm playing hide and seek trying to find where it is. ... I think it could've been more stable. ... You can still vacuum without the brush attached though, but I think it's pretty vital for pushing dust into the vacuum."

"it couldn’t just mop by itself"
"It can't tell apart floors from carpets, so it'll mop over carpets and dispense water over them, so you need to manually restrict carpet areas on the map as a no-mopping zone."

My S20 will just ignore barriers like this.
r/RobotVacuums • Best robovac that'll cross thresholds? ->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
r/RobotVacuums • Advice needed - not interested in mopping ->I ran my old combo Xiaomi on the vacuum + mop mode as it couldn’t just mop by itself and with regular use, the motor became much louder.
r/Roborock • Qrevo slim first impressions - coming from someone who has never owned a robot vacuum ->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.
r/RobotVacuums • Xiaomi S20 vs S40C ->Hi! I also have the S20 and I really regret this buy… it’s a dumb robotvacuum, it bumps into everything and every 5 minutes gets stuck on something. I had the first gen Mi Robot Vacuum Mop, 5 years old, and it’s smarter than this one. Knowing what I know now, I would totally avoid it, the sensors are useless, and every time it’s backing up, it goes full force and crashes.
r/RobotVacuums • Xiami S20 Robot Review ->Ich hab einen Xiaomi S20, der hat ca. 160€ gekostet. Ich hab viel Parkett und ein paar kleinere Teppiche und war von der Arbeit des Roboters positiv überrascht. Die Karte ist super präzise und die Sperrzonen funktionieren perfekt. Die Wischfunktion hab ich noch nicht ausprobiert. Ist aber vermutlich nervig, weil man den ‚Lappen‘ von Hand drunter klemmen muss.
r/Ratschlag • Lohnt sich ein günstiger Roboter-Staubsauger oder sollte ich mehr investieren? ->I just bought a Xiaomi s20 for £98. It’s been awesome!
r/homeassistant • What's the best robot vacuum and mop IYO? Is it really worth its expensive price tag you paid? ->Seems to work fine!
r/homeassistant • What's the best robot vacuum and mop IYO? Is it really worth its expensive price tag you paid? ->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. 🫤
r/RobotVacuums • A great functioning robot vacuum WITHOUT self-empty feature and WITHOUT mop ->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.
r/RobotVacuums • A great functioning robot vacuum WITHOUT self-empty feature and WITHOUT mop ->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.
r/RobotVacuums • This doesn't have to be an agonizing decision. ->Hi everyone, i bought the same robot because i have a little kid that started crawling around recently and we had to mop and vacuum everyday so the robot was great addition and help for my wife while im at work. My only problem was that the robot couldn’t climb the 3cm lever between rooms, so I made little ramps to help it pass thru rooms and it works perfect. You can use wooden board as well, I hope this will resolve the matter for you as well.
r/RobotVacuums • Xiami S20 Robot Review ->I have s20 and he can easily “jump” over lets say char leg that is L shaped, and those legs are like 2-3cm thick so he can not on first try but he will lets say take step back and just go at it and easily jump over it, i do not regret it 😆
