Excellent Robot Vacuum, Especially for the Price
Top reviews from the United States
There was a problem filtering reviews. Please reload the page.
- Reviewed in the United States on August 5, 2018Style: Slim 11SVerified PurchaseBackground: I have a shedding dog, so I bought this in hopes that by running it every-day, it would pick up on some of the dog hair on the floor.
What I like:
-VERY easy to use.
-easy to follow instructions
-has a sticker on the bottom so if it ever stops and beeps, you can flip it over and it says exactly what the beeps mean (one beep means one thing, two beeps means another--which is SUPER helpful!).
-color on top clearly shows what mode it is in (blue-ready to go, orange-needs to charge, red-problem to fix-such as emptying the tray).
-very quiet. I can work on stuff with it in the room and it does not bother me at all (my dog also does not mind it).
-works great on white carpet and easily transitions from my living room to dining room (which has a slight bump).
-when its low on battery, it does not die where it is at, it just turns off the vacuum then finds the home doc and charges itself.
-just works really well. I run it everyday and I am impressed by how much stuff it gets (especially when it goes under things such as the couch).
-if it gets caught on a cord, it usually takes 5-10 seconds but then it stops the suctioning and moves away (releasing the cord or other item). However if you have a small cord you should put it up (and you should regardless, I just noticed it doing this a few times and thought it was neat, but I do try to pick up all cords).
What could be improved:
-nothing really in particular to this.
-It does not work well on anything black, but this is true for all robot vacuums. It sometimes gets stuck when it goes on the black carpet we have with the black chairs (I suspect because it can not detect them), but this has not happened often. My dog has a black mat for her food and water and it always bumps into it and spills the water, but again, this would occur with any robot vacuum.
-Also, make sure the doc is against a wall because otherwise it will move and never charge (self explanatory, but I did not do the first time and it kept trying to doc and was just pushing the doc around the floor).
-Finally, you do have to dump out the vacuum particles almost every time you run it (if you do a full circle/battery cycle). It is really easy to dump and beeps when it needs to be emptied. Again, nothing really negative, just something to note.
Overall, I really like this! It does a nice job cleaning up the dog hair and other things that get on my floor and saves me a lot of time not vacuuming daily. If you have a dog, I would watch them with this first before you use it. My dog was initially scared of it but sniffed it's "butt" and now they are cool and she does not mind it at all. Pleased with this product and would recommend! :)
**UPDATE**
On another note, Eufy has amazing customer service! I received an email from them addressing each of my "what could be improved" components with more information on the product. Very impressed.
- Reviewed in the United States on March 27, 2025Style: 11S MaxVerified PurchaseI have had this robo vac for about a week now and still testing it out. It has a remote control and is very easy to use. I have 2 dogs and had to sweep my floors almost every day. I had to empty eufy the first 2 days of running it. I run it every day and each day it is less full and doesn't have to be emptied as often. I will continue to run it every day. The amount of dust alone (not including pet hair) that is picks up daily is surprising. Every 2 or 3 days I will take my swiffer and go around, between and under furniture where the vac can't get which takes me about 15 or 20 minutes to do. So far I have been very happy with the job the vac is doing. The is a big time saver for me. It is so nice to have clean floors.
- Reviewed in the United States on April 18, 2025Style: 11S MaxVerified PurchaseThis basic robot vacuum is awesome. I have a shedding Labrador that makes frequent vacuuming a chore. This vacuum may not get every spot but it picks up substantial amount of dog hair, navigates on hard wood and wool rugs well. It does get stuck in certain places so I cannot "let it go and forget about it". It comes with a remote (no wifi or smart phone connection) and you have to manually empty the debris but I wanted something basic so these are not issues for me. This robot's simplicity, lower price, and effectiveness for my cleaning purposes make it a winner.
- Reviewed in the United States on May 1, 2025Style: Omni C20Verified Purchasei had used roomba for over 10 years and it seems like they just have not improved theirselves i had even bought one prior to this one and had nothing but trouble from day one..ended up sending it back and decided to try a different brand .... this one by farrrrrrrrrrr is more advanced than a roomba .. i have absolutely loved this one since day one ... setting up the app was a bit of a challenge but once you figure it out .. it works very well.. mapping is great ..will do room by room .. different levels of vacuum and when it docks it sucks all the dirt out of the vacuum not what is just in the bin .... the filter too.. the roomba you still had to clean air filter every other day

5.0 out of 5 stars Excelente producto!
Style: Omni C20Verified PurchaseExcelente producto. Tardó mucho más de lo estipulado en el inicio del pedido y hubo unos detalles con la información que asigna Amazon y la paquetería que me generó estrés y mala impresión del vendedor. Sin embargo el vendedor muy amable se comunicó conmigo y me dió datos correctos del envío y la posible fecha de llegada. Super bien embalado, producto nuevo, alta calidad. Super fácil de poner en marcha. Ahora ya está limpiando y es muy fácil de usar. El segundo artículo de este tipo que tengo. El primero me duró dos años (otra marca más económica) esté se ve de mucho mejor calidad y espero dure mucho tiempo. Muy satisfecha!

5.0 out of 5 stars Cool unit, doa and shaky support so far
Style: Omni C20Verified PurchaseEdit: Support has reached out to make it right, they have replaced the entire unit and the new one is flawless. Does a great job of cleaning, wish it had better objext avoidance but it does a good job regardless.
Original: Vacuum mode works great but the mop disposal is broken, says "abnormal water level in dirty tank" and refuses to continue.
So far support has been stone walling me with questions and canned support responses asking for videos of the unit, when the issue is internal while docked.
Want to love it but can't even test it properly.
Edit: Been days since contact and 0 help from Eufy after intial "send us proof" Avoid this product/company and get something reliable since support won't help out.

5.0 out of 5 stars EXTREMELY QUIET
Style: 11S MaxVerified PurchaseUpdate, May 15, 2024: Today the new battery lasted 100 minutes.
Update, May 8, 2024: I sent an email to the manufacturer explaining the battery situation and they sent me a new battery under warranty.
Very poor manual because of very small illustrations which are not the same as on the robot, plus does not explain how to delete a setting. A fairly good robot though, cleans well but tends to remain in larger rooms, it starts in the living room of 1,500 sq.' apartment, manages to find the bedroom, but once it exits the bedroom it does not go back to finish the bedroom and washroom. My fix for this is to put it in the bedroom and close the door and let it run until it finishes the bedroom, then take it to the living room. It does not clean near the charging station. Very quiet, bumps very gently. When it is working beside you, you can still hold a conversation.
It is very easy to clean the waste bin, roller, wheels and filter. I clean it and wipe off the machine each time I use it, which is twice a month. I find this vacuum very easy to use and clean. It usually runs for about 1.5 hours, then recharges.
For $200.00 Canadian it is an okay value. It does not have the headaches and problems associated with programming using cell phones. I understand why manufacturers went that route, but it isn't good.
TIPS: do one room at a time. The reason is that the robot learns the room and wastes less time learning multiple rooms. Give it plenty of time to fully recharge between uses. CLEAN IT, CLEAN IT, CLEAN IT after each use - remember to do the wheels, they pop out so easily.
