One year in- DONT DO IT :(
Size: 01-X10 Pro Omni Black, Size: 01-X10 Pro Omni Black
ONE YEAR IN REVIEW
I have mixed thoughts because I really like it, the app is great, it cleans great. I’ve stayed on-top of all the maintenance the app has asked me to do and found replacement parts here and there as needed. I have it run everyday and it does a great job, works about as good as I could have imagined in terms of cleaning.
Unfortunately exactly one year after purchasing it, 6 days after the one year warranty expired, I started having issues. For about a week I got the same error of “roller brush stuck”. I cleaned the brush, paid for replacement parts, followed every trouble shooting suggestion in the app, same error. Contacted support and did everything they told me to do in terms of trouble shooting. On Reddit I learned this is a common problem and probably from a motor issue. Worked with support for a few weeks and eventually they offered to repair it for me, even though it was a few days over the warranty. Super stoked with that. But had the weirdest interaction with the support people, felt like I was dealing with some like 3rd party questionable service, just not the interactions I expected for such a “high end” expensive product. Contacted them through the app, got an email response and they sent me a shipping label. I packed it up very well, wrapped it up, and sent it off for repair. Like two weeks later get it back on my doorstep, in the same box I sent it in, but all squished. Vacuum just set ontop of the same bubble wrap I sent it in, but like not wrapped or protected . Device was clearly beat up, everything in the box was wet and there were random parts scattered throughout the box and a panel missing from the top of the vacuum that wasn’t even in the box. Also just realized MULTIPLE parts are missing. I’m not only missing a random panel, but also a brush guard, filter and dust bin, all pieces that I sent in. I literally feel like I got scammed. So confused and disappointed. For like a $900 vacuum and only one year out, I’m disappointed to have had such a major issue so quickly and to have such an unprofessional experience with the service group. I’ve never seen something packed so poorly and was shocked, like actually dumbfounded to have found that parts are missing and like such an obvious one too, literally the panel on-top, I noticed it before the box was even open all the way. I couldn’t tell you if it worked or not because with exposed wiring and chips from the missing panel plus all the other missing parts, it literally cannot be used, it’s useless. No idea what to do now besides pray they sent me parts or just replace the thing.
UPDATE:
40 something emails later I finally begged someone to send me a new device. Their original suggestion was for me to buy all the replacement parts they took and they would refund me 15% back, ridiculous in my opinion, but I literally cannot buy the most important part, the top panel that was stolen, it’s not something they sell. The “new” device they finally sent me was all scratched up with dirt, gravel, kitty litter and cat food scattered throughout the packaging. The vacuum was literally covered in the gravel and all scratched up. Clearly a returned device that was sent back dirty and no one cleaned it up before sending it to me. I thought it was all cleanable but the scratches were deep and one is right over the camera. I asked if I could exchange it and was literally told I should be grateful they sent me anything and they wouldn’t help me anymore…
The customer service is so bad it’s just not worth it, get something else, save yourselves the struggle.
Because of all this, I wouldn’t recommend this product. For the price, I’d expect it to last more than a year without a major repair issue needed (replacing the motor) and I’d expect better customer service and a better warranty. Stay away, it’s too expensive and too risky :(

Eufy 30C is MARVELOUS!
Size: 07-C30
I purchased this Eufy 30C after 6 months of chiding from my sister, who has one. Eufy - where have you BEEN my whole life!
I have uneven saltillo tile floors in this home - I was sweeping floors nearly everyday just trying to keep the floors clean in this desert environment. On a daily basis, I just could NOT keep the floors clean enough for our barefoot habits. This vacuum cleans VERY well! I turn it loose every day - it cleans under furniture and beds, it cleans my lower-nap area rugs very nicely. I use the Auto mode (random cleaning pattern). The bumper is gentle on furniture legs and walls, the sweeper automatically goes into/out of baseboard cleaning - it cleans all along the walls! Most rugs I can leave in place and let the sweeper clean those, also. The few rugs that do get caught up in the brush, I just pick up before starting the cleaning. I have moved cords so they are permanently not in the way, so I only had to deal with those issues once. The suction on this vacuum is terrific - the combination of the spinning side brushes and the roller brush pick up everything. If the sweeper has been there, the area is spotless! It moves easily from floors to rugs. I normally run the sweeper as we are having breakfast - it is very quiet, although a little "rattling" as it moves across these saltillo tiles. I have used the daily programmed mode, but personally prefer to run it when I am "ready" (some rugs picked up). The vac does not ever seem to "miss" a room using this random pattern, and eventually it seems to get everywhere in a room. It just roams around the house and does it's thing - WITHOUT my help, and better job than I did on a daily basis!
I have a large, heavy-nap area rug that I prefer to run the regular sweeper on once a week rather than have my Eufy waste sweeping power there. I placed the boundary strips under the very edges of that rug to keep the Eufy off. This works most times although, occasionally, Eufy finds his way onto that carpet, anyway. I have to remind myself, but I do use an upright sweeper on all the rugs and a canister sweeper for the tile about every one to two weeks.
I empty the waste container everyday when cleaning is finished (I am always amazed at how much this sweeper "finds" and picks up!). I also clean the filters everyday with a small, battery powered hand vac (opposite the direction of airflow of the Eufy). This seems to remove the fine dust from the filter. I did purchase an additional filter set. Each week, I change the filter to a clean one, and wash out the used filter under running-spray tap water and let it dry. The filters are disposable pressed paper (and a small foam filter sheet that is also washable), but I have interchanged these two filters for 6 months and they are still working just fine. Emptying the waste container and cleaning/changing the filters is extremely easy and fast. I clean the roller brush of hair and carpet fuzz as needed.
I have contacted the company with questions and they were extremely responsive. I also had the brush guard replaced from the company without any issues or questions at all. Customer service was very nice. (I believe the uneven tiles just wore on a very small rubber piece and it eventually came off. Looking back, I really don't believe it affected the performance of the sweeper, or the brush guard, at all. If it happens again, I probably will not bother to replace it).
I cannot think of one dislike I have of this Eufy 30c. I believe the price was extremely reasonable for the excellent job it does. It has made a big difference in the attitude I have about this house as the one, most annoying, issue I had - seemingly constantly dirty floors - is now a non-issue. If this sweeper broke down tomorrow, I would have trouble getting another here fast enough!

Great products and great price!
Style: Kit
Great value for quality products! We love how well this kit cleans everything and gets it looking brand new. Buying separately in the stores near us would be almost twice this price. Highly recommended.

This product worked great. Just used it on two different cars and they looked shiny by and new after using this brand. I will buy again when the need arises.
