Okay, so this thing is actually a life changer for a couple reasons. 1) We have a labrador. Even with consistent brushing, her hair is always EVERYWHERE and coagulates in corners on the floor and under our couch (which this robot can scoot under). 2) I now am horrified at the realization of how much crap and nastiness accumulates in the floor of a house within 24hrs. I'll never be the same. The pictures of the dust bin below are from single runs 24hrs apart in our small, carpeted bedroom. EVERY, SINGLE, DAY, this little robot picks up an ENTIRE bin's worth of dust and hair from our bedroom, as well as a full bin from our kitchen and living room which is hardwood. It's actually insane - it's not like we live in a palatial mansion, they're normal sized rooms - and I'll never look at the floors of my house the same ever again. As far as the robot itself (which I've affectionately named Ding Dong), it's adorable and does everything it needs to do efficiently and effectively. It's a little louder than I expected it to be, especially when it's running over carpet or when I have the vacuum power turned all the way up, but since I'm running this during the day, it's a complete non-issue. This thing could sound like a jet engine in my living room and I would still give it 5 stars because of how well it cleans. The app is also intuitive and easy to use. I don't like that it requires wifi to work because I'm a privacy fiend, so I set it up with an old cellphone on a network that's only used by roborock and other smart home devices. The beta mapping feature works wonderfully; I have my rooms setup and can quickly tell Ding Dong which rooms I want her to clean. The app also has a maintenance category which will keep you informed on when routine tasks should be performed, such as cleaning the brush or replacing a filter, as well as an instruction manual built in to help you through your first days of usage without needing to flip through a booklet. Other appliance app developers should be looking at this one and taking notes. I should also mention that we got almost $200 off the list price because of the Amazon sale and another coupon I found online, so for me, the price point was great. If I had needed to pay $429 or $499 (current list price), I don't know that this would be five star. I do feel that $500 is a bit overpriced, especially considering the discontinuation of the S4, which is what I was originally intending to purchase. Having a more expensive model (eg, the Max) is all well and good, but the price is a bit more problematic when the original model is no longer available (ESPECIALLY when there is a *visciously competitive* market for used or "open box" S4s on resale sites like ebay). I also wish Roborock would change their website to reflect that the S4 is no longer sold; currently, the page for the original S4 links to this listing here for the Max. I find that misleading. So, overall, since I was able to buy the S4 Max at a steep discount, I'm over the moon with this purchase. Ding Dong is a huge time saver, and within the span of a week, she has made a noticable improvement to the air quality in our house... So much so that I'm starting to form a belief that access to a robot vacuum should be a universal right. If you've got the extra cash and have been holding off pulling the trigger on a robot vacuum, let me be the first to suggest that you treat yourself. I really don't think you'll regret it; even at MSRP of $500.

I've only had my Roborock S4 for short time, but I'm very impressed. I'm the veteran of 3 previous robo vacs and this is the first one that actually does what it's product description advertises. I'm sick of vacs that randomly clean, don't respect boundaries and don't clean very well. 1. It does very well near stairwells. I have an open stairwell on my main floor going to the lower level and 2 previous vacs have made s swan dive down the stairs or through the opening to the floor below - one just ignored the boundary strips and went right over. This guy went up to the stair opening, paused, and backed off - every time I've run it and I've kept a close eye on it when it gets near the stairs. Its cliff sensors really work. I've now drawn walls and a no-go zone as added insurance but I feel pretty good about it not making the Thelma and Louise dive the previous 2 did. 2. It's a quality vac. It just feels more sturdy and the brushes are rubber and don't seem to tangle as much. Also, you can wash out the filter - this is a real bonus cause those suckers cost a bundle. They suggest that you do clean it and rinse it between uses. 3. I love the mapping. Once you run it for the first time, it creates a map in the Roborock app and you can then create no-go zones or virtual walls. You can also send it to just one room or area to clean. I just tried that out and had it go to the furthest room from it's base and it made beeline right to the room, cleaned and returned to the dock. 4 It is efficient and I love, love, love the lines it leaves in my carpeted spare room - something I never achieve when I vacuum. 5. I previously ordered a Roborock 5 last year but returned it when I couldn't hook it up to the internet - but that was my error. I didn't realize my phone wouldn't automatically pick out the right band - this only connects to 2.4gh, not 5. It's easy to connect and the app is easy to understand. Also, there are a couple really good tutorials on YouTube to show you how to use the app features that I found helpful I figured out that I had to change the wifi connection to 2.4 on my phone with the Amarey I ordered to replace the Roborock I returned - Amarey is one of the vacs that took a swan dive and now only runs in circles or one corner of the room. Anyway, I got so frustrated with that piece of crap I started looking again and saw they had redesigned the Roborock 4 to work without mopping (I didn't want mopping) at a much cheaper price than the 5 or 6 models. Actually, I'm glad it turned out that way because I love this guy so much. It is exactly what I envisioned when I found I wanted a robot vac. One thing - make sure to clear your floors and move chairs in your kitchen or dining room the first time you run the vac while it's making it's initial map. That way it gets a clear vision of your floor plan. You won't have to do it every time afterwards. Also, I have a dark bathroom with no windows and it mapped it but didn't clean it the first time I ran it so I turned on the light the next time and it went right in and has gone in since. If you are looking for a good mid priced robot vac - check this guy out.

Es el segundo robot de limpieza que compro y me llevé muchas gratas sorpresas. Comencemos por el principio: Configurarlo es muy sencillo, aunque debo decir que quizá adultos mayores con poco contacto con la tecnología necesitarán algo de ayuda. Compré una para mí y una para mis padres ya grandes y tuve que configurar ambas. Los sensores anticaída y antigolpes son maravillosos. Tengo otro robot que a veces se queda atascado en los desniveles porque se precipita, pero éste va suficientemente lento como para percibir con tiempo que hay un desnivel o un objeto. La función de mapeo es verdaderamente útil. Vi al robot mapear y atorarse en algunos lugares difíciles, pero en la segunda o tercera pasada ya había aprendido dónde están los obstáculos y los recovecos y había determinado la mejor manera de limpiar sin arrastrar la mugre de un lado a otro. La función de fregado fue satisfactoria para mí. Ningún nivel de agua quita manchas pegadas, pero creo que es genial usarlo para mantener limpio fregando seguido. Yo tengo perros, lo hago cada tercer día, es muy fácil y se mantiene limpio. Solamente cuando hay manchas las quito con una servitoalla antes de pasar al robot. Me encantó sobremanera que con el depósito de 300 ml de agua y media cucharada cafetera de limpiador especial para robot, puede fregar toda mi casa, evitando el desperdicio de agua. El vaciador automático de polvo no me gustó del todo. Funciona solamente cuando es polvo fino, pero si lleva pelo de perro denso no siempre lo vacía. Debido a que mi casa se llena de pelo de perro, siempre debo vaciar el depósito manualmente, así que el extra que se gasta por el vaciador automático no valió la pena para mí. El equipo viene con un mop original de la marca, pero honestamente es muy delgado. Prefiero los mops genéricos que venden también aquí en Amazon, son más gruesos y absorbentes. Con este robot puedes limpiar la casa completa, (un mapa), una sola habitación o un área delimitada. Recomiendo ampliamente a las personas que les gusta mantener su casa limpia con el mínimo esfuerzo, pero también para los obsesivos compulsivos de la limpieza (yo estoy en el segundo grupo). Realmente creí que ningún robot podría satisfacer mis expectativas, pero éste lo hizo. Actualización después de un año de uso. El robot sigue funcionando muy bien en la mayoría de las superficies. Aspira y levanta pelo y polvo sin problema. Lo único malo es que la función de fregado ha fallado en una de mis habitaciones (enfatizo que solamente falla en una habitación y solamente es el programa de fregado, por lo que creo que se trata de un error lógico). Comienza a moverse como acostumbra pero de pronto se vuelve errática y marca el error de que hay obstáculos cuando realmente no hay nada enfrente. La he reiniciado a sus valores de fábrica un par de veces y eso corrigió el problema, pero está tercera vez ya no funcionó. La limpio con regularidad (cada semana) y le he cambiado el filtro y los cepillos, pero nada funciona. En el servicio a cliente me dicen que los sensores deben estar sucios y que por eso no funciona, pero ni están sucios, ni tendría sentido que fuera eso porque entonces fallaría en todas partes y en todas sus funciones. Hasta ahora no he podido solucionar el problema.

You're paying a premium for two features here : vacuum intelligence and in-app mapping. Those two features were important to me so I didn't mind. If you don't care about those things, go for a cheaper model like Eufy. If you mind, the S4 is a damn good choice. The mapping is outstanding, controlling this vacuum from my smartphone is surprisingly convenient, you can also point it to a place so it only goes there, was useful to me as i cook a lot with flour. The S4's map makes it smart and efficient, it will do the contour of the room, then zigzag in straight lines as much as it can. It also doesn't care about most carpet, only struggling with the highest ones we use as a welcome mat. It had issues with bar stools, as it tried non-stop to climb the rounded sides, but I was able to setup a no-go zone in the app so it ignores the bar stools. Great mid-range vacuum. If you wanna spend the money to get past entry-level products, this is a great choice.

Click to play video This is my first robot vacuum so maybe my review isn’t as helpful as someone who owned 10 of them. It’s been only a week since we got this robot, but I absolutely love it!!! I was debating between this model and Q5 and so happy I went with this one as I love mopping capability and find it extremely useful. Use it few times per day every day to keep our 2 story condo as clean as possible with two little children and a cat. It works perfectly for hardwood floors, we have only one room with a small carpet and I think it’s so-so for carpets, but probably none of the robot vacuums are good for it. (IMHO) Overall, this was an amazing purchase and I look forward to keep using it.

Mapeamento rápido e preciso. Limpa os ambientes de forma bastante eficiente. Único ponto é que poderia ter algum tutorial disponível para aprender a configurar, mas depois que aprende é bem tranquilo.

I’ve owned a Roomba and a Shark and a Eufy to it vacuum. This is by far the best one! Picks up all the dust, dirt and dog hair, cleans the floor. I wish the washing function worked a little better, the model below this one washes the floor better in my opinion. I do like the LG water tanks, they only need refilling every 2-3 days. Overall though I’m very happy with this item
