roborock S4 Max Robot Vacuum with Lidar Navigation, 2000Pa Strong Suction, Multi-Level Mapping, No-go Zones, Ideal for Carpets and Pets Robotic Vacuum

I rely on reviews heavily when making purchases, yet I don’t take the time to write reviews for the many, MANY things I purchase from Amazon— until now... After researching numerous robotic vacuums- both well-known brands and brands I had never heard of before, I ordered the Roborock S4 Max. Best purchase I have made in a while and already well worth the money! I received the vac quickly and the set up and operation was so easy. I downloaded the app, connected to our WiFi, and everything has worked flawlessly. Our house is a little under 2,000 square feet and it vacuums our entire home on one charge (takes about an hour and 40 min., with over 35% battery life left upon completion). We have mixed flooring- most of the house being hard wood, and then carpeted bedrooms. It goes over and adjusts for each flooring type and gets our rugs, as well. The noise level is very quit and the suction is great. I wondered if I would second guess myself not getting a self-emptying vac, but I am glad I did not- there was no need! When I empty it after it has cleaned our entire home, it is full, but not overflowing (we have a cat that sheds and children running in and out of the house bringing things in on their feet, too. Just remember to turn the unit over occasionally to get the hair out of the brushes- we have three girls with long hair in our home). I have used the vac both while being at home and while away and it is so easy to see where it is at right from my phone. It maps out our home perfectly and gives detailed information such as meters cleaned, battery life, and amount of time it has taken. You can also create no-go zones and choose specific areas to clean, if you desire. This was a fantastic investment and has already saved me hours of cleaning. I have nothing but positive things to say about this machine and hope that its longevity is just as great.

The media could not be loaded. [Only 11 days in, so I'll update this as we approach the warranty limit. 2022.02.27]LOVE this machine! Praying it's well-built and lasts, because it is wonderful. Why? Lemme tell ya.First, the miracle: our motor-phobic, prey-obsessed herding dog CAN STAND THIS VACUUM! When I ordered it, family members expressed loving concern that perhaps I'd lost my beans. I had the great hope that maybe, just maybe, I could run the thing inside a closed room while I entertained Mr. Dog far, far away and outdoors. Living the dream, eh? I rather assumed I'd be sending this vacuum back. I visualized the moral struggle of wanting to buff out bite marks while knowing that would be wrong, very wrong indeed.Instead, I'm floored (hahahahah) to report that I can actually run the Roborock S4 Max ("Max") with my dog INSIDE the same room. For real. Nobody who knows Mr. Dog would have have taken that bet.Our long-haired, 68-pound purebred herder hates with a passion lawnmowers, motorcycles, and my screaming-loud upright vacuum cleaner. He can't stand the whines of a hand mixer, electric juice reamer, coffee bean grinder, drill, or manual crank-powered radio. Thankfully, the electric shaver and toothbrushes pass muster; and after much work, over months, I got him able to cope with a popcorn popper.As for things that move, he is an arch-enemy of squirrels, crows, hawks, bees, spiders, ants, slowly twirling ceiling fan blades . . . you name it. He growls at and chases brooms, mops, and long-handled shovels. He has even sometimes attacked the damp paper towel with which I'm attempting to wipe up his hair while crouched on the floor, a wheeze-inducing, poor substitute for the vacuuming I've neglected since his adoption. Until we got Max the Bot, it had been getting really gross around here.Anyway, something about the sound of the Roborock S4 Max motor may be key. It's just not very shrill at all. A quite quiet little whir. Another unexpected blessing is the motion of the machine. For reasons I'll never know, it doesn't set off Mr. Dog. Even the little rubbery, spidery finger things are not triggering. I had to do some desensitization training, sure, but no biggie. Day 1 looked good. By Day 3, we were off to the races! Metaphorically speaking. Mr. Dog does NOT chase Max. Nor bark at it. As I said, a miracle.I've been using this thing nearly every day. It needs two attempts on most rooms, but what do I care? I'm SO fricking happy not to be lugging my mighty, insanely loud vacuum around in a sweaty rush while stowing my dog at someone else's house, or negotiating with another human family member to do it for me. Our household dirt includes a lotta long dog hair plus splotches of potting soil from an enthusiastic houseplant lover who's recently moved back in with her parents. But two passes does the job.You can read the specs and comparisons and pros and cons, but here's the deal for me:(1) Works with nutty dog! That's enough right there.(2) I don't have to interact with any other humans to make vacuuming happen. I just press a button and walk away.As for all the fancy features, yes, they work, but I don't care much. Most important, the thing vacuums well and can usually find its charging station without help. If not, no big deal to pick it up. So far, I haven't even bothered to program the invisible walls and such. I just put the bot where I want it to clean, press the button, and walk away. Easy to block an area with shoes or other objects if desired (e.g. laundry basket at top of stairs allows humans and dogs to pass, but not Max the Bot to tumble). Getting texts from the vacuum when it's done is hilarious.As for human factors, I've asked non-asthmatic family members to empty the wee bin, which fills up quite quickly with dog hair and dust. It's such an easy task, though, they don't mind. We DO have to pull out long hair from the twirling brush and front wheel most days, but no worries. There's no way around that, even with a mighty vacuum.As for models, I picked the cheaper S4 because I wasn't ready to pony up for a unit that can also do wet-mopping. Various reviews made me think S4 would be as good as S5.Can't think of any cons except the cost and wishing I'd got this thing earlier. It's heads and shoulders above the automatic floor dusters we tried 20 years ago.Crossing my finger it lasts! So far, absolutely thrilled.PS: I have a friend with one of these. Same model. She's worked it hard for months with no issues. She reports with delight that her adolescent and adult children now routinely PICK UP their charging cords and hair elastics and earrings and sewing doodads and other goodies from their shared living space every day. Hmm, who know when Mom programmed that thing to go off? Such a bad memory, tch-tch-tch. Yeah, it'll eat a cord. Ya don't want THAT.

I love this thing. I've never had a robot vacuum before, so I can't compare to other models, but this one seems fantastic to me. It's extremely good at navigating around my apartment and around the random obstacles that I forget to pick up.The app is very intuitive and user-friendly; it's easy to set up schedules and partition the map into named rooms. Setting it up on my wifi was also fairly painless; that's usually the biggest pain point for smart devices, but Roborock has found a reliable way to do it. Make sure you go into your vacuum's settings page and update the firmware as soon as you set it up to get the latest and greatest cleaning algorithms.Cleaning performance seems excellent. I have a dog and two cats but it doesn't seem to have any problem picking up all the pet hair, on carpet or hardwood. It reliably switches over to maximum suction when it goes onto the carpets. It is also low profile enough to go under most of my furniture, which is a really nice benefit to having a robot vacuum. The last time I moved out of my apartment, I had the nastiest dust bunnies and hair clumps under all my furniture. 😅There are a couple small areas in my home where it often gets stuck or the brush gets caught on cords. It's really easy to draw "no-go zones" on the map so that it doesn't try to vacuum those areas.Emptying the dust bin and cleaning the filter is super easy. The dust bin is large enough that I only need to empty it every 3-4 days in my 850ft² apartment with three pets. I also appreciate that the maintenance schedule is automatically tracked in the app so I will be reminded when I need to clean the sensors and replace the filter and brushes.Siri shortcuts work well. I can say "Hey Siri, vacuum the bedroom" and it starts heading over there within a few seconds.All in all, this is an amazing little machine and well worth the price. I know my floors will be cleared everyday and that has given me a lot of peace of mind at home.

I did lots of research before purchasing Roborock S4, there are lots of robot vacuum on the market. We think Roborock is by far the best robot vacuum.
