OKP K4 Robot Vacuum, Robotic Vacuum Cleaner

This bad boy puts in some work! You can program it, so I set it to run at 9:30am and 9:30pm. When I first set it though it was automatically set as “arranged” I had to switch it to “random” so he would leave the kitchen. I have 3 dogs and 3 humans, so a lot of hair everywhere. But it’s not a problem for Phineas. He fills his dust collector everytime! Make sure you tuck away cords, he is a multi surface cruiser. We had no problems with connecting to WiFi. He is not very loud. It’s soooo helpful that the brushes aren’t like regular vacuums, they kind of sweep the dirt in so there’s minimal hair stuck. I’ve only removed and cleaned the brushes once in 10 days. He puts himself to bed. He’s great. I’d recommend this to anyone looking for a good robot vacuum without spending the money on name brand.

Was absolutely awesome. It lasted me over 3 years before it finally gave out. It stopped charging but I think it broke because we had a huge storm with power surges and I didn't disconnect it so it might had been my fault. Battery life was amazing and I was really impressed with that. I used it only on tile floor in my kitchen and living room so I can't comment on rug. This particular model only had the "random" cleaning feature meaning it does not record where it has already cleaned. It could repeat the same spot multiple times but I honestly didn't care about that. Those intelligent models always break, stop, get stuck, because of the extra sensors. This little guys was borderline bullet proof. If I wanted it to clean a different spot, I would move it with my foot to the area I wanted. I was mean and abusive to it and it never once broke on me. I got a cat for the first time and didn't want to let her be inside the house because I know how much they shed and didn't want hairs all over the furniture and having to constantly clean the floor and didn't want that cat lady smell in my house. Because she was super young, didn't have a choice but to let her be inside sometimes (especially during bad weather) which is why I bought this robot vacuum. It picks up so many hairs (and trash) that I would have never known where there or have been able to clean. My floors are constantly spotless and no cat lady smells as far as I can tell because I run the vacuum cleaner constantly and often. Great product for the price point.

This OKP vacuum was purchased by me on 7/2/23. Vacuum worked satisfactorily and performed well up until late May 2024, wherein the vacuum no longer appeared to be charging - so the vacuum is currently not operational. Power switch would go on for a moment before turning red and proceeding through a series of beeps. I contacted OKP technical support on 5/29/24 via email to resolve the problem with this vacuum no longer working. Email communications continued through June 2024 and are continuing as of today (July 11, 2024) trying to resolve the problem with my OKP not working. Through the process of elimination, one replacement part was forwarded to me and has been replaced and multiple pictures of the internal workings have been exchanged as technical support continues to troubleshoot the problem. The latest communication from technical support indicates that a new battery for this OKP is needed (cost approx $45 at my expense). However, our email communications that started in May 2024 regarding this problem have now gone beyond the 7/2/24 one-year warranty period, and my discussions are currently ongoing with technical support as to whether or not a new battery will be provided to me to resolve the problem with my OKP since we started the process well within the warranty period. Technical support has been good up to this point but now we are at a standstill about the battery being provided. I am hopeful that they will provide the battery under their 1-year warranty program since this process started well inside the provided warranty period. I will provide an update to this review - either good (they sent the battery) or bad (they refused to honor the warranty), once this matter has been resolved. So currently, my OKP is sitting in a corner — not operational. I will post a follow-up once this matter is resolved. As of today (7/15/24), I have been advised that a battery has been shipped. Update 7/28/24. A new battery was received as promised (minus instructions). But able to figure out how to change the battery - relatively simple. Was so excited to see the blue power light come on. My OKP K4 is now working once again. :):):). Kudos to their technical support, who did not give up on trying to resolve this problem even after the warranty period expired, keeping in mind that this problem started within the warranty period.

I have at least 7 of these grey ones. I've gotten rid of all the Eufys that I started with. THIS REVIEW IS FOR THE GREY ONE ONLY. The OKP K4. It sucks up at 3600 pa, and that is A LOT of power. NO BRUSH to clean. Extremely simple. [And I have two golden retrievers and four cats.]. My whole house is set up for automatic vacuums. So they never get stuck, because I've worked out all the getting stuck areas. I don't map. Or use the app. What's important to me is that my over 2000 square foot house gets clean. I turn them on, on each floor when I leave to work out. When I come back, all the floors are clean. I'm gone for about two hours, and they run at least that long. They use random movement because I don't map. But they run so long, they eventually get everywhere. As a PS: not having to clean brushes is BIG TIME. I do meticulously tap the dust out of the filters every single time, and change them once a week. YES, YOU CAN WASH THEM OUT -- very easy and non-time consuming. And these vacuums are cheap !! I've tried the others -- don't get them, they're not powerful enough. But these grey OKP K4's are the bomb.

Nachdem mir bereits zwei Geräte kaputt gingen, schickte mir der Hersteller das Ersatzgerät, welches erst gar nicht funktionierte, sondern bereits defekt war. Und das natürlich nur unter Voraussetzung einer besseren Bewertung. Nun habe ich keinen Support mehr etc. sehr enttäuschend.

Klein aber fein. Gefällt mir sehr gut das Gerät. Super leicht zu reinigen. Saugt toll.

I love it !! This is my second one, I have one in each of my 2 houses I would highly recommend buying one So easy to set up, detects stairs, so it won’t fall down

Easy to use straight out of the box Easy app download and setup Easy to clean Easy to control thru app

Thee best buy so far in 2024!! Love this wee gadget. It hoovers all of downstairs going from room to room. It even hoovers upstairs even the landing carpets and goes on the rugs. Its brilliant, helps keep floors clean for a quick going over with no effort! 3 hours and it's charged!
