    • Difficult to connect to Wifi, works GREAT after
Color: White
Don't recognize the brand? Well, neither did I. Who's ever heard of "Dreametech"? I was out shopping for a RoboRock to replace my horribly performing low-end non-mapping Roomba, as this was what a friend recommended as being much better value for the money and a good performer. Well, turns out that Dreametech is actually another line from the same maker as RoboRock, and both are products of the excellent Xiaomi, makers of a variety of quality phones, tablets, and other consumer devices. This became apparent when I installed the "Mi Home" app to manage the Dreametech vacuum. This vacuum is an unbeatable bargain for what you get. I was looking to pay a bit over $200 for the most basic mapping vacuum I could get. Mapping was important because I've learned from experience just how inefficient the non-mapping can be. It bumps around using random selection from a set of algorithms -- go straight, turn a circle, do a weave, etc. and it ends up hitting parts of your floor over and over and over while other parts never manage to luck into any of the algorithms finding those sections. That Roomba would spend the entire 1.5 to 2 hours of its battery life bumping around, getting stuck in one room for a good long time, getting stuck under some piece of furniture where I forgot to wedge some kind of barrier, and then eventually running out of battery in the middle of a room because it doesn't know where the dock is and it has to bump around until its line-of-sight sensor happens to see the dock, assuming it can luck into that before the battery finally dies. Now the Dreametech: Not only did I get a full MAPPING unit, but BONUS, this one also has a LIDAR which as far as I can tell is usually found only on the much more expensive models -- not even on the more expensive non-LIDAR IR sensor-based mapping models of other brands. I paid around $160 for this one on Amazon Prime Day, but I see that at least at the moment the apparent going price is $200, with a list price of $300 -- I have no idea if the $200 is some kind of sale or just Amazon's typical "better than list". Anyway, even at $200 this is a really good deal. The one issue I had was getting it connected. I had problems with the app wanting to work at first on my phone (a Google Pixel 7 Pro) but got further with it on my Lenovo Duet chromebook (which runs Android apps), and even further installing it on an old retired Samsung phone that I charged and factory reset first. At this point, I was able to at least get to the part where you're getting it to connect to your WiFi. I struggled with this, as it would just get stuck at some point and never finish the connection. I'm using a Synology RT6600AX router which uses a single SSID for both 2.4 GHz and 5 GHz bands, and this vacuum says it does not support 5 GHz but does work only with 2.4. I thought maybe it was trying to get the 5 GHz since I can't specify one or the other (router is supposed to autonegotiate as needed) so I created another SSID just for 2.4 GHz and started trying on that. It didn't seem to make a difference, but I stuck with that just in case. Eventually after enough trying one small change after another, rebooting the phone over and over, rebooting the vacuum and resetting over and over, turning off every security feature on the router, etc., SOMETHING ended up working. It isn't clear WHAT exactly made the difference. I had even tried bypassing the router entirely and even my ISP by setting the Pixel 7 Pro up as a hotspot going right to its own 5G cellular network. So literally everything in the chain was tried on multiple devices with multiple settings and in the end something worked but who knows what. It did end up having a connection to the 2.4 GHz only SSID on the router with security turned back on (at least after the fact), and that's how it is now. So once that was connected, everything was good. I was really to the point of being ready to contact tech support. The first run does vacuum your house, but more importantly, this is when it's learning where everything is. I did put barriers this time where it wasn't safe to go (under the couch, into a bundle of cables, etc) and let it find all of the walls, furniture, rooms, etc. Once it's discovered all of this, you can edit the map and tell it which parts are off limits for vacuuming, and which are off limits just for mopping. That's a little awkward to edit, but it works, and no need to ever buy those expensive "no vacuum" boundary markers or special tape or whatever. I marked my couch, the cables, the entrances to the rooms I don't want it in, and cat bowl areas where it might bump and make a mess. It dutifully goes right up to the edge of these no-go zones and skirts around. The whole routing is WAY more efficient than I'd seen with the Roomba. It goes room to room, circles the entire valid area for that room first, then starts a back-and-forth systematic series of rows to get the job done quickly. The suction is terrific even not bumping it to the stronger level (which also consumes more battery and is louder). I've left it on medium and I'm very happy. This vacuum does my whole relatively small house in like 35-40 minutes, leaves a really clean floor with no missed spots, and then goes right back to the dock. Contrast with 90-120 minutes, leaving a lot of debris even where it went, and maximal debris where it didn't even go, and dying in the middle of a room. This vacuum is also much quieter than the Roomba was. I can't hear it if it isn't right near me. Further, the dirt chamber is fairly large next to the old low-end Roomba, and much easier to pop out and empty. It isn't, however, large enough that I could let it do more than one session without emptying before the next. I can't schedule it for routine runs for that reason alone, as it still seems to fill up rather snugly from one run, thanks to having 3 cats who leave hair, tracked litter, and thousands of tiny pieces of the cardboard scratching pads all over the place. As if that weren't enough of a reason I can't just schedule for runs, there are tons of cat toys and various cardboard boxes left on the floor for cats to play in which need to be picked up before a vacuum run. Your mileage will vary on that. A friend does fine with scheduling because less debris and no unpredictable toys and such. Mopping: I've used this just once. It was easy enough. Fill this clip-on module with water, stick on a velcro mopping pad, and start it vacuuming. It detects the add-on and knows it's in mopping mode. Those places you don't want a mop to go are avoided. For me, that was entrance mats, chair mats, etc. I don't have carpet so most of the floor was good for mopping. You are instructed not to add any cleaning chemicals to the water, so it's basically just plain water being applied over your floor with a relatively thin textured fabric pad. That isn't going to suffice for real mopping, but if you do that now and then, it'll help get up some of the grime that comes along between real mopping sessions. Don't see this as a replacement for actual mopping, just a supplement, maybe a way to not mop quite as often. In all, even with the serious pain in getting it to connect to WiFi, I'd buy this same unit again and recommend it to others who might happen to have an easier time or at least has patience to work through getting connected, maybe with tech support's help. If you can get past that, the unit itself performs extremely well and is unbeatable on price for what you're getting. ... show more

    • Great vacuum for the Cost
Color: White
The media could not be loaded. TIP FOR ROBOT VACUUM USERS: This is a tip for any robot vacuum user. Maintain and clean your robot at least twice a month. No matter how "smart" the appliance, it's still an appliance that has no arms or legs so can't clean itself. Cleaning the robot takes less than 5 minutes. Empty the bin, cut or remove as much hair as you can caught up in the main brush and the side brush and dust the sensors. That's it! Take care of you robot vacuum and it will take care of you! I bought this robot vacuum on May 2021 and have been using for 3 months straight now. We use it at least once a week on standard/strong suction mode and mop maybe twice a month. I'll update again after a year on May 2022. I did a lot of research into getting the best robot vacuum in my price budget and this Dreame D9 has not let me down once. Though there were two occasions where the app that controls the robot went a little wonky but it was an easy 5 minute fix. Nothing horrible or inconvenient. I did think about waiting until the latest Dreamebot L10 came out but comparing it to Dreame D9 the additional features of the L10 weren't significantly enough to what I needed though the stronger suction power was really attractive. My house is about 2000 sq ft in total with my two floors combined together. The ground floor is about 1200 sq ft and cleans the entire floor in one go, on full battery, without having to recharge on standard and strong setting with the carpet booster feature on. There are five rugs on the ground floor. When it's cleaning a floor and needs to recharge, it does takes a while for it to recharge enough for the robot to resume cleaning (maybe 2-3 hours) but I mean, it's not like you're cleaning the house so why be impatient, haha. It does eventually resume cleaning once it's got enough charge. It easily cleans the second upstairs floor in one go on half battery. Four low-pile carpeted bedrooms and a hardwood floor hallway. In the 3 months that I've been using this robot, it never once alerted me that the vacuum bin was full and to empty it. Although, I always start a cleaning with an clean empty bin, keep the house fairly clean because I run the robot to clean once a week and the whole house is about 75% hardwood and 25% low-pile carpet. The bin never got full because of the huge bin capacity. Bigger than most other robot vacuums. But, the suction does its job and definitely filled the bin with all the dust and dirt you can't see with your eyes so it's not a matter of lack of suction or power. The plus here I'm trying to make is the huge bin capacity which means less of a chance of the robot stopping and alerting you to empty out the full bin to resume cleaning. Depending on how much carpet is in your house, how often you clean with your robot, and the pile height of the carpet. The higher the carpet pile, the more dust and dirt can be trapped and the quicker the bin will be filled. It will send an alert on your phone when the bin needs to be emptied. This robot cleans in a very organized way with back and forth lines and keeps those lines tight to each other to make sure that every pass the floor gets cleaned to the inch. This robot has never once gotten lost trying to return home and can handle the typical cord thicknesses that you may have on the floor or forgotten to pick up. But if it's a jumble of cords together, the robot will have a hard time getting out from it. I forgot to pick up a bunch of cords in the office that were connected to my PC and it was a puddle of cords together and I could hear the robot struggling but I got to it in time to release it and it didn't stop and continuing cleaning. The robot goes over AC vents just fine, though it might make a loud sound as it goes over it but it will go over it. The neat feature of the app that I really appreciate is the accessory usage feature. If you click on your device and then on the three dots on the top right hand corner and go to "Accessory Usage" it shows you the life percentage of the filter, the side brush, and the main brush to keep track of when any of those accessories are nearing it's lifetime end and time to replace it. Even if you app disconnects from the device or disconnects you entirely out from the app (which is what happened to me), I was afraid that usage percentage would reset back to 100% but the accessories usage never resets as, I'm guessing, the usage information is stored in the robot itself and sends that information to the app when it connects/reconnects. Replacing the accessories for this D9 is quite inexpensive too so the replacement costs are a nice pro. I gave overall 4 stars because of the battery recharge time and the noise. It takes about 4-5 hours to fully recharge the battery from a low battery setting so it may not always be possible to clean a house of my size in one day. But if you're house is less square footage than mine than it should easily be possible. The noise level on the standard mode is actually not that loud or distracting. Kind of like a nice background white noise but can still watch a movie comfortably without being distracted by the robot. The strong and turbo suction modes are, of course, louder and can be a little to mildly distracting if you're watching a movie. Other than that, this robot vacuum is great quality for the price! I compared my robot vacuum choices from Roomba, Roborock, Neato, Eufy, iLife, Proscenic, and Coredy when deciding on a purchase. The DreameTech company is fairly new company established in 2015 and started making smart cleaning appliances until 2017 but the products seem very well-built and of quality for the price. The company was founded and based in China but I've come to find that despite that, the stereotype of products from China being of poor and cheap quality doesn't apply to this product. It's well built, consistent in usage, and rarely had errors or issues come up. ... show more
