Roborock Obstacle Avoidance Systems Compared & Tested! S8 Pro, QRevo, S7 Max, S7 MaxV & S6 MaxV.

If you have ever wondered how Roborock's Reactive Object Avoidance systems compare this is the video for you as I put all of Roborock's robot vacuums in a head to head obstacle avoidance challenge on carpet and hard floors. In this video I compare the Roborock S8 Pro Ultra which has Reactive 3D to the S7 Max Ultra with Reactive Tech, to the S7 Max Ultra which also has Reactive Tech to the S7 MaxV which has Reactive AI 2.0 and finally the first Roborock with Object Avoidance the Roborock S6 MaxV with Reactive AI. I did not include the latest release which is the Q8 Max+, but it also has the same Reactive Tech object avoidance as the Q Revo and S7 Max so it should perform the exact same.

One week into ownership, the Q Revo is truly amazing. Are there more expensive models that might be a little better? Probably, but the Q Revo can hold it's own at a fraction of the price. We bought direct from Roborock for 680-10% military discount, total cost $612. Much to our surprise it successfully avoided a folded blanket we forgot to pick up, so while it's obstacle avoidance might not match models costing twice the price, it's fine if you pick up cords and such. On the plus side, it does not touch, bump, or markup walls or furniture. We even have Christmas decorations out that it successfully avoids. None of our previous Roombas or Deebots could do that. Q Revo for the win for us.

Another awesome video Jamie!! S7MaxV still shining!!

[@jamie.andrews]

Thanks

[@speedlever]

Very nice review! It just confirms my recent decision to go with the s7 maxV plus over other RR models. My only suggestion is that I would like the obstacle recognition system be able to recognize when an obstacle previously marked has moved during the same session and now it’s ok to clean that spot that was marked to avoid. It’s hard to keep my dogs in one area during a cleaning session and I frequently end up with missed spots because the dogs moved after being detected and that place was marked to avoid.

[@O1dmanwalker]

Thanks Jamie cause of your videos I brought the s7 max v ultra and I'm enjoying it

HAPPY BIRTHDAY JAMES

[@mikeyfl]

Another great video, Jamie! Hard to top the S7 MaxV Ultra with dryer module and water fill kit!!! Though SwitchBot's upcoming s10 looks to be raising the bar!

[@jamie.andrews]

Thanks much! Love the S7 Maxv, but the L20 has me real distracted right now!

[@mikeyfl]

@@jamie.andrews, nice! That L20 ultra looks like a great option for the money. Maybe next year Roborock will bring better obstacle avoidance to next Q revo, and bring new innovations to flagships for worthy upgrades and increased competition!

[@ThunderShoe]

Hi Jamie, First off, many many thanks for the video reviews and comparisons you have made on all of these robot vacuums! I am in the market for my first robot vacuum, and your insights and testing have been invaluable. I'll echo another commenter who said that I think you're giving the Vacuum Wars channel a run for its money with your quality. I've been zeroing in on a few models: the Q Revo (best price atm = $800), L10s Ultra (best price atm = $700), and the S7 MaxV PLUS (best price atm = $584 for certified refurbished, 2-year warranty). I'm thinking to pull the trigger on the S7 MaxV PLUS since my original target budget was $500-$600. I know that the Q Revo and L10s Ultra may go on sale if I wait around. I also realize that the S7 MaxV Plus doesn't come with the ultra dock, but I'm thinking I can live with manually cleaning the mopping pads. I also have a little one who will be starting to walk soon, and I'm thinking the better obstacle avoidance of the MaxV could be worth it. I'm also wondering if I really should be looking at a lower price range for my first robot vacuum given my needs - since I don't have any pets and my home is on the smaller side, maybe something cheaper would satisfy me. A few questions: 1) Do you think I would be satisfied with a lower budget robot vacuum, and if so, which models would you recommend I zero in on? 2) Do you think the auto-mop cleaning feature of the Q Revo or L10s Ultra is worth the additional price/wait vs. getting the S7 MaxV Plus now? 3) How much longer would the S7 MaxV (or Q Revo and L10s Ultra) last compared to a budget pick - in other words, is it worth the higher cost in terms of potential longevity? Thanks in advance for your help!

[@jamie.andrews]

It kinda sounds like the L10s has everything you need without questioning yourself or having any regrets. I am not fond of refurbished vacuums, but I also know they no longer sell the S7 Maxv so if you want that robot it is your only choice. If you really want the S7 Maxv and if you plan to mop it is not a huge deal to wash your own pads. Plus you could take the money you saved and buy a real mop like the Dyad Pro or Dreame H12 Pro and have the best of everything. 2 things most people obsess over is 1. Object avoidance. 2. Edge cleaning with a robot. Object avoidance is not really needed if you don't have pets and you pickup before it run. If you want to run it while you are away it might make more sense to have it. Edge cleaning will never be perfect with a robot. Not yet at least.

[@ThunderShoe]

@@jamie.andrews Thanks so much for your reply. I pulled the trigger on the MaxV Plus given there were only a few left in stock so I didn't want to let the deal slip away. Returns are free so I will keep researching. Hmm, I never really considered a separate mop but will look into it now. Did you have any thoughts about getting a budget unit in the 300-500 range like the Q7 Max+ or the D10s Plus?

[@ThunderShoe]

@@jamie.andrews Checking back in! I have been using the S7 MaxV for the past week or so and have been disappointed. On most fronts, it has lived up to what reviewers/users said it performs well with, e.g. navigation. However, my disappointment stems from its very poor performance with my low pile carpets, especially with picking up hair, and hair in general seems to be an issue for this vacuum - I began to research this hair issue and see quite a few other users encountering thsi problem. I have been running the vacuum at its highest settings and even tried swapping in a compatible hybrid brush from the Q5 that has bristles, but that did not improve the performance. I am now seriously considering returning the S7 MaxV. Do you have any recommendations for improving the performance? If I do decide to move on, do you think the L10s will perform better than the S7 MaxV on carpets and with hair? Or is there another robot vacuum that you would recommend instead?

[@carstenandreasen3196]

Hi Jamie, Great video. I am really enjoying your reviews. Very detailed and thorough, and always with some very good points. Is there a review in the pipeline for the Dreame L20 - almost had my mind set on the Q Revo but the poor obstacle avoidance is a bit of a problem. Seems like Dreame L20 has that down quite well and with the rotating mops I would really like to see you take it through its paces.

[@jamie.andrews]

Ty! The L20 is not yet ready for sale and has a few bugs that I am waiting for them to fix. I am working with Dreame.

[@carstenandreasen3196]

@@jamie.andrews thanks for your reply. What bugs would that be ? are we talking showstoppers or mere minor inconveniences ?

[@jamie.andrews]

@@carstenandreasen3196 showstoppers, but they are fixing them so I have been waiting before putting out my review.

[@carstenandreasen3196]

@@jamie.andrews it is for sale here in Denmark now, was going to order one for Delivery Monday. But maybe i should wait then.

[@jamie.andrews]

@@carstenandreasen3196 I am running a beta firmware to fix a big issue. Not sure when it will be pushed out.

I really hope the P10 Pro will be available in Europe soon and will perform the same as S7 MaxV. My S7 MaxV Ultra died recently and I wanted to replace it with some newer model, but having kids and seeing the poor peformance of obstacle avoidance in other models, I will either have to wait for the P10 Pro or get another S7 MaxV Ultra. The P10 Pro seems like a perfect match for me, having mostly hard vinyl floors, with its warm water spinning roller mopping. Or is there any other alternative?

[@plainlybasic2300]

Interesting to see! So far my Q Revo has been very good about avoiding socks and shoes here, but I'm wondering if that is because our socks and shoes aren't completely black. Maybe due to such a dark color it cannot sense them as well? Either way, good comparison!

[@jamie.andrews]

It very well could be as black is a hard color to detect which is why I use it. Thanks!

[@user-gd1mm7gw8k]

Bright room/lights helps. i use remote flash light in my robot it see all the socks now.

[@st3yn]

While Roborock still makes some class leading models, they really need to step up their game in some areas: - Laser obstacle avoidance does not work well on any model (Q Revo, S7 Max UItra, S8 Pro Ultra) - There are too many different models with only small changes - Naming of models is completely confusing. S7 Max? MaxV? Ultra? Pro Ultra? Q7? Q7 Plus? S7 Maxv Plus? Q Revo? What's going on. - The S8 Pro Ultra is overpriced. The double rollers are nice, but the usecase is scarce. I returned mine, a much cheaper Q Revo or S7 Max Ultra will perform 95% for 40% less €. - Spare parts are all over the place: dust bags for the S7 Max Ultra and S7 Plus have a different closing system, the Q Revo also has weird bigger dust bags. Mops the same, 2 rotating mops or 1 big vibrating mop. Choose 1 system and stick to this. - New useful software features are barely introduced. For example, when my S7 Max Ultra vacuums at night during DND hours, he won't empty the dustbag in the dock to prevent noise. The next day however it doesn't empty itself automatically. I have to not forget to run it manually. A feature for this has been requested a million times, but Roborock refuses to add really smart features to their software. I really love their Robots and the app, but their business strategy is to flood the market with too many models and different parts, making it hard to make a decision or understand what's going on. Dreame is starting to release some very interesting models with loads of features, the L10S Ultra offers much more value than most high-end Roborocks. If Dreame starts investing more in their software and Q&A department they can give Roborock a run for their money.

[@Janak_Desai]

Yould yoz please do a comparision of the L20 Ultra and the Q Revo? Those are the models i am mostly considering to buy atm. Weather to take the bang for the buck QRevo, or the featurerich, Corner cleaning L20 Ultra with its current Software struggles.

[@jamie.andrews]

I keep getting these requests so I will consider it after I put out the full review of the L20. Curious why not the L10s Ultra which closely competes with the Q Revo?

[@RichyNeal]

I can concur with the findings in the S7 max ultra. On the one I recently purchased it just ploughs through objects. The kids left a set of headphones on the floor and it just didn't see them.

[@jamie.andrews]

Yea it really puzzles me as to why it even exists at all. I don't think I have tested a worse object avoidance system to date.

[@MrBlueCreeper]

The P10 Pro in China has a watered down version of the S7 MaxVs Object Avoidance which has RGB cameras but no crossed lasers.

[@jamie.andrews]

Yes it will be interning. I think ideally both are needed in my experience.

[@MrBlueCreeper]

@@jamie.andrews yes, Reactive AI 2.0 is one of the best Obstacle Avoidance systems out there

[@RogueDalek]

Thanks for this video Jamie. I had an S8 Pro Ultra on order, but after seeing your video I cancelled and got an S7 MaxV instead. Although I'm only 24 hours in, I'm already glad I made that decision. My main concern in changing was whether it would be good enough to pick up pet hair from carpet (coming from a Roomba S9+ which did an excellent job at this), compared to the higher suction and dual rollers of the S8, but it seems to be doing the job so far and the object avoidance finally means I don't have to patrol the house beforehand.

[@jamie.andrews]

Glad to hear and glad I could help you out! The S7 Maxv is a great robot.

[@itsagreatbear]

will there be a review of the dreame l20 ultra?

[@majasako]

That is what I'm waiting too. Compared to L10s Ultra and Q Revo etc... 😄

[@jamie.andrews]

I am working on it now. I got behind as I went out of town for a week and came down with covid. Hope to have it out soon!

[@danfarber1321]

Thank you Jamie. I don't understand how is S8 Pro Ultra worse than S7 MaxV if it's using additions like cameras etc? It seems like overall the S7 MaxV Ultra is the better choice (going to get one this week probably).

[@jamie.andrews]

MaxV is better than Pro. Hopefully we will see an S8 MaxV soon.

[@mikearrigo5674]

Great comparison, I'm wondering if the S7 MaxV has been discontinued, it no longer shows up on the "store" page of Roborock's web site. The Q8 Max Plus looks interesting, I'm really thinking of getting the Roborock Q Revo, I can get it for $699 and for what it does that sounds excellent. I don't have any pets and I don't leave cords on the floor so I don't really need the object avoidance and I actually disable it on the bots I have that have this feature. There are a few new robots out that look really nice. The Eufy X8 Pro sounds like a great self empty robot and the new Ecovacs X2 sounds amazing. Irobot also has their new combo J9 but they are still behind the times. They are still using VSLAM instead of Lidar, for mapping, Lidar is better by far. The dock fills the tank on the robot but it still does not clean the mop pads or dry them, and the mop pad does not vibrate or spin.

[@jamie.andrews]

The QRevo should suit your needs based on what you said. I have all of those robots you mentioned and I am working on testing so keep an eye out of them.

[@mikearrigo5674]

@@jamie.andrews Looks like Roborock has another new model out, the Q5 Pro Plus, there are so many robots out now that it's hard to keep track of all of them. I have a feeling that the Roombas are going to still fall behind the competition, I noticed you just posted a new video about Dreametech's newest model, I'm guessing this is the sequel to the L10S Ultra.

[@jamie.andrews]

@@mikearrigo5674 It is in addition to the L10s as they will sell both. It is pretty impressive.

Does the S7 Max V not come with a self-cleaning mopping dock feature? I only see the Max Ultra with it on amazon.

[@jamie.andrews]

The no longer sell it unfortunately.

[@daniele6479]

Hi, I was wondering if the obstacle avoidance of the Q8 Max is worth the 110 euro difference with the Q5 Pro. Since robots are otherwise the same.

[@jamie.andrews]

The mopping system is much better too. The Q5 has a small non electronically controlled mopping system. If you don't care about mopping the Q8 is not really needed as the object avoidance is not great on it.

[@t0nkatsu]

@@jamie.andrews I don't think people are concerned about privacy when the robot is cleaning, it's just when it's sat at the dock. I don't want my robot viewing the entire room while it's doing nothing, but connected to my WiFi and potentially exploitable if a software weakness is found. The camera needs to face inwards so it can't see anything when docked, or they need to install some kind of automatic camera lid that closes/opens appropriately.

[@jamie.andrews]

@@t0nkatsu I hear all the time from people that they don't want a camera roaming around the their home. Fortunately for your case all of the Roborock models with cameras do face inward when docked.

S8 works much better if room is bright or using lights. i was using mini flashlight in my S8 and it helps.

[@jamie.andrews]

Something might be wrong with yours then if it is not working well in dark areas. The object avoidance camera up front is a nighttime IR camera designed to work in total darkness. You should not have to use a flashlight with it at all.

[@MattZiggy]

They need to come up with better names. They're so convoluted and confusing. I ended up buying the S7Max Ultra thinking I purchased the S7VMax Ultra. Doesn't even make sense. It's a lower tier than he S7VMax, just change the name entirely. Why does a S7Max come out after an S8+Max or whatever that's called? They have the best robots, but their marketing department need to do better.

[@jamie.andrews]

Complely agree.

Trust me the newer S7Max Ultra is way better than the S7VMax, there are comparison videos online, they all concluded the same, it doesn't use a video cam though

[@jamie.andrews]

@@harjpannu I'd say it is better in most but not every way. Some people do not like the integratedwater tank and the non removable mopping plate. Then the obstacle avoidance is a big downgrade.

He's really impressed although doesn't leave wires on the floor, but yeah the model names are ridiculous
