"A good robovac is a life changer. Even a $350 basic S8. It is a great place to start. ... I promise you that you will not be disappointed by a basic S8. It will change your life even if it can't fit under every piece of furniture you own. ... My two S8s just finished vacuuming our entire house in about 46 minutes. ... While my floors were being cleaned, I sat comfortably on our patio in the cool shade with a slight breeze and composed my far too long response to you while sipping a diet soda and relaxing. ... I will have to spend about four minutes maintaining my two S8s. This will be my entire contribution to my home floor cleaning effort for today. Four minutes!"
"Like 500$ these robots are currently the steal of the century ... You can get a mova p10 pro ultra (cannot remove its mops), equivalent to the l40/x40 for 500$ after a discount code"
"I got the Q5 Pro for $139. ... costs $450 less than what I paid for the S6 ... it is the best value option out there imo."

"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."
"My cat has very bad mite allergies, and this vacuum is a must have for us for keeping the floors clean of all dust, dander, and dirt."
"The second floor of my house is all carpeted, and I used to clean with a Dyson V8, but since I got the E28, I haven't vacuumed myself."

"I think its hands down the best all around option right now, especially once you hook it up to the water line and drain, i run it daily in our house and we got rid of our cleaning help because of it."
"I have an even thicker rug than this and my Curv has no issues ... It's the reason I bought mine because I have an even thicker rug than that and no robot could even climb onto it"

"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."

"that sumbitch craves toy mice. ... Nothing can sate its bottomless appetite for cat toys. ... it refuses to avoid the cat toys."
"The object avoidance is pretty horrendous."
"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."

"I have a roomba we named homewrecker because it leaves a trail of destruction behind it. ... It always knocks over something or gets tangled up in wires."

"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. ... I plan to buy a wire organizing box to fix this. ... Also If you have long curtains that drape to the floor, set it as a no-go zone for sure."

"The side brush keeps falling off while vacuuming. ... This new model is the only one where the side brush snaps on, instead of using a screw. ... Our house is new, we don’t even have furniture yet, and still the Roomba keeps losing the brush mid job. ... without the side brush it just leaves all the corners and edges dirty. ... I can’t be looking after it monitoring where and when the brush falls off."
"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 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."
"it couldn’t just mop by itself"
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 ->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 ->My living room is 3cm higher than my kitchen and could not climb over…
r/RobotVacuums • Xiami S20 Robot Review ->My 2 cents: - Brush needs to "click", requieres some pressure. Made the same mistake but it never got detached after that. - Cannot go over a 2cm bump to get into my kitchen, but can go over flip flops or similar... Who knows how that works. - Bumps into things, usually not hard, but sometimes yes (again, go figure). - Area that goes over in my aparentement is around 60m2 according to the app, which consumes around half the battery (half in turbo, half in standard, only mopping a small area)
r/RobotVacuums • Xiami S20 Robot Review ->I have this vacuum for 6 months now. So the little brush has to “click” on the vacuum. I never had it be removed by itself before. I have 2 cats and two huge carpets, and this vacuum does amazing job vacuuming them (on turbo). I would disagree regarding the noise, it’s okay, not like an actual vacuum, slightly less noisy, but you can hear it. Regarding bumping, vacuum itself is made with an extra movement allowing the robot to clean in very tiny spaces, corners and similar. It won’t break anything. Mine does a great job scanning stuff and it never goes over flip flops and stuff. The only time I had something stuck in it was a napkin. It seems I don’t have a control thingy, this depends on the area that is originally selected. Mainland china is great for app updated, however this robot can’t be find on the list for that region. Also, keep in mind that you won’t get notifications unless region is actual as the Wi-Fi. It won’t climb higher than 2cm, but it is interesting looking at its wheels work up and down to climb things. I would recommend having the water department empty if you needed to climb anything. Also remove mop pad when you want to vacuum, especially carpets. I don’t find it as a minus that it does not recognize the carpet, as there’s an option to select areas that you don’t want to be mopped, or vacuumed. Additional plus for this model is that it has option for professional mopping, and it does wonders. It actually cleans very well. For the price, I think it worth every penny.
