"The roborock I have kicked and smashed with my foot so many times out of anger when it doesn't collaborate, and still he rocks 4-5 yrs later and no broken parts"
"they are extremely durable. ... I’ve got well over 1000 miles out of a pair and they still have grip and the uppers are in great shape"
"I've used them for 1500 miles of multi-day hiking with no issues!"

"I run the X10 daily on schedules, and it has never been stuck even for once, isnt that amazing? The navigation and obstacle avoidance is truly amazing. It is almost a true set and go experience."
"It also doesn’t bump into stuff, slows down and turns around before running into anything. I am impressed. ... The navigation is night and day between this and J9+, no more bumping or getting lost. ... I think it’s better, it has the front facing camera which looks to be higher resolution, plus the LiDAR does make a huge difference to the speed of navigation, plus it doesn’t bump into furniture or doors anymore."
"The best feature of the L40/X40/p10 pro ultra is that they have class leading object avoidance so you don't have to pick up your cat's toys or prep your house every time you want to run the robot meaning you can run it on a daily schedule which will keep your house cleaner. ... I run my X40s daily and they never get stuck on cables, cat toys and other random junk that ends up on the floor."

"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."

"It did a perfect job so far, I only have to empty/fill the water tanks in the station once a week (the robot vacuums the whole flat everyday and mops the flat twice a week)."
"We have four roborock S7’s running in our 5,000 sqft office. ... Bought them since they first came out years ago. ... They run every day. ... Only last year did we replace the battery for all 4. ... Other than that, no issue at all, rock solid, very pleased that we also have them for our homes too."
"What I really love is how little effort it takes—the base cleans and dries the mops on its own, so I barely have to lift a finger."

"VibraRise works ... especially if you spray some floor cleaning solution on the mop before installing it, it works wonders!"
"The S8 can mop, and is a huuuuge upgrade compared to the Roomba."
"my mopping roborock really did a number of gross floors. ... It has a vibrating mop pad instead of spinning things and it really did a good job."

"Hair Pickup on carpet is better than the S7 MaxV but still worse than the Neato D7. ... I confirmed this by running the S7 Max V first (with rubber brush), on my upstairs carpeted room - that I purposely haven't vacuumed in a week. S7 Max V barely got anything and had some wrapped around the edges - as it does. ... For me yes but I say that mostly because of the tangle free vacuuming of pet hair and the improved hair pickup on carpets. I was tired of cleaning out the old one and so far with this I have zero tangles. ... The S7 MaxV had the worst hair pickup on carpets, with the stock rubber brush, of all the bots I ever owned. Tangles were minimal but it didn't do well taking hair off the carpets (it did great on the hardwood/tile though). Swapping out the rubber to the bristle brush improved the pickup but increased the tangle problem - it also created a problem with auto-empty for me a few times. ... It mops/vacuums significantly better than my S7 MaxV. Especially on carpets (especially especially pulling dog hair off carpets). ... That being said I LOVE the anti-tangle brush. 3 Months and I haven't had to clean the brush one time. It's literally perfect for me."
"quite frankly, it's sh*t. ... It can't handle pet hair ... but it just doesn't deal with pet hair."
"J8+ barfs hair clumps over one of our rugs ... My J8 leaves hair clumps even when run daily. ... If I run the vacuum every day it’ll do the rug just fine. May leave 1-2 ropes. If I don’t run it every day, there will be more. ... The borders of the rug is where there are always ropes. ... I can run the robot twice and there will be ropes. ... I can run the Dyson then the robot and there will be ropes. ... I can pull the edges up, dyson under the rug, then Dyson the entire top of the rug and the robot runs—guess what I get along the edges? Ropes. ... However in real life my J8 is a fail in this use case. ... J8+ is meh for Pets. ... the j8+ barfs hair clumps all over one of our rugs."

"it is also way more prone to tracking pet messes about, that happened once with a pile of cat vomit and I was a little traumatized."
"it has alleged pet accident avoidance. Well silly me, trusted that, dog had an accident and the vacuum smeared it all over the floor and the docking station. ... I had to manually clean it and have turned off the schedule clean functionality. Will do a manual start after checking the room for pet accidents."
"Firmware currently needs fixing as obstacle avoidance failed poop test ... But the same cannot be said about the obstacle avoidance and navigation. ... If the weird obstacle avoidance gets fixed"

"The biggest downside to an S8 with an automated dock is the mechanism the dock uses to clean the mops. It is complicated and requires enough maintenance to keep it from filling up with gunk and debris until it clogs. Cleaning this mechanism is more difficult and time consuming than with models that use spinning mops."
"I will not recommend a fancier S8 because of the mechanism required by the docks to clean the mop. It is too complicated and requires too much maintenance. ... If good vacuuming ability sold robovacs, we would all be buying S7s and S8s. But their mop cleaning system is terrible and requires too much maintenance."
"Cleaning the dirty water tank was a pain on my Roborock and required weekly deep cleaning or it smelled horrible."

"Roborock refused to cooperate or properly fix the issue while still under warranty! ... Their customer support is all through email after you call the 1800 number, and their response was basically we replaced the board in the unit and base station what do you want us to do? ... well they never emailed back. Calling the 1800 number you get the "were so sorrycwell escalate this and you'll recieve an email soon." No email just silence."
"they would no joke die consistently 2-3 months after their warranty expired. 3 of them in a row, like clockwork."
"replacing my shitty Nighthawk router. ... craving a solid stable experience as opposed to the weekly-to-daily wifi drops and router dementia every 6 or so months. ... same dementia and wifi dropping issues for all the nighthawk products. ... the wifi radios just turning off for 5 minutes at least once a day, if not more, or dropping until the router is rebooted at least twice (Ethernet is fine at this time); ... Mainly it's the first two issues: random factory resets and radio dropouts. ... I would have figured maybe I had a bad router, but it's happened across 3 different models, one model I have two of that did the same thing."

"when the roborock would empty its dustbin it would always wake her up as I run it overnight"
"I hated that my Roborock would try to send data to Chinese servers. Luckily I saw the traffic on my firewall and was able to block it."
"the self emptying vacuum feature can get loud"
One big issue that I haven't seen covered - dustbin *effectiveness.* A HUGE issue on my Q Revo Curv, in a household with dogs, is that the dustbin opening is small - that means that hair and dust has limited room to enter and all just bunches up near that hole, not spreading out throughout the bin. As a result, it gets clogged quickly and 3/4 of the dustbin's volume is wasted. The S8 Pro Ultra I upgraded from had a much wider opening and I never had these issues with it.
r/RobotVacuums • How Can We ( Vacuum Wars) Catch Real-World Issues in Robot Vacuum Reviews? ->I have a roborock S8 - it does an ok job - valetudo is not supported yet as roborock have gone to lengths to prevent it using different encryption keys on the bootloader, I guess they want your data and need it connected to their cloud. Maybe this is because it has two cameras on it. The dust bin is small so if you have carpets it fills up quickly with fibres. The option for auto emptying dock is very expensive The solution is to vacuum more often than you would normally then it doesn't fill up so fast. If you are privacy focussed and want valetudo look at what is supported and recommended by those folks
r/homeassistant • What's your TOP PICK for the best Robot Vacuum Mop today? ->I have the Roborock S8 Ultra and with 3 pets, I absolutely love mine. Best investment I ever made. I will say the mop function doesn’t do a perfect job but it’s good enough to keep me sane throughout the work week. I have it vacuum and mop every day during the week and then on the weekend I have it do a double vacuum and I steam mop once myself. I clean the unit and change the mop pad once a week and that seems to be good enough.
r/CleaningTips • Will I regret getting a robot vacuum? ->Can anyone share their experience with the obstacle avoidance of the Q10 S5+? How does it handle cables and small items like socks? I previously had the S8 and it did a pretty good job with avoiding obstacles and generally was a great robot, I decided to upgrade to a model with an empty station and wondering if I should I go with the Q10 S5+ which is more budget friendly (and has the smallest station I saw) or maybe invest in the pricier s8+
r/Roborock • My first robot: the elusive Q10 S5 ->Lmao these numbers i bought an s8 refurbished with 20 hrs usage for 200 and it changed my life
r/Roborock • Should I drop $1800 on a robot vacuum or go cheaper? ->It's definitely an upgrade to the standard dragging a wet cloth. Flagship Saros 10 is using vibrarise too but its a bit more updated and has more vibration and downward pressure. Not sure how big of a difference in terms of performance it is compared to the S8. If you can find S8 for a good price then I think you wont be disappointed I also think when choosing between rotating and Vibration mops its about preference and what type of floor you have. The rotating mops are using more water I believe and could have a tendency to leave wet streaks on floors
r/Roborock • Is the VibraRise System of the S8 worth it? ->This absolutely clocks with my Outlook, which is actually quite reassuring. The S8 Pro was the best that I had ever tested until I tested the S8 maxv ultra and it replaced that.
r/RobotVacuums • Vacuum Wars - Please explain to me ->ThW s8 line from roborock is great.
r/RobotVacuums • Every Prime Day Robovac and Recommendations ->S8 pro. I know that this is an incredibly overwhelming and confusing decision, and in an ideal world, I would now give you 800 reasons to support why I said that. But it would be super duper double rainbow awesome if you just trusted me.
r/RobotVacuums • Roborock S8 pro or Eufy S1 pro or ecovacs x9 pro Omni? ->Get a Roborock, I recommended mine (S7 or S8) to my friend with 3 dogs and 1 cat and it keeps their floors so nice. It (no exaggeration) saved her sanity. It’s pricey, but it actually works and works well. You have to keep the base station maintained but it’s so simple to clean.
r/CleaningTips • Robot vacuum VS dog hair… battle to the death 💀 ->Also have an s8 with vibrarise. I’ve read that the super “in” dual rotating mops aren’t proven to be better than vibrarise. What I will say is that I think mops on robot vacuums are still a “maintainer/extender” feature than a true mop up stains type of feature. If you manually mop, the s8 will make it so you have to do it less often. It’s not a replacement for that first initial manual mop. Besides that, I’ve enjoyed the s8 as it was an upgrade from my original s4. Obstacle avoidance is pretty good, although, I’m just used to tidying up before running it now a days.
r/Roborock • Is the VibraRise System of the S8 worth it? ->I have a roborock s8 pro ultra and its great. The integration works well and the vacuum does its job well. You do have to use the roborock app to set it up initially though which can be a dealbreaker for some people though. For me I dont really care as long as I can ditch the app after setup, which you can. >must be silent when it goes/comes back to clean a single room starting from the base I think you would be hard pressed to find that. Its a machine it isnt going to be silent. Its definitely quiet but not silent.
