I purchased the OKP Life robot vacuum in 2024, and as of 2026, it continues to perform exceptionally well. It has proven to be a highly reliable product, exceeding my expectations in terms of durability and long-term performance. This device has significantly simplified my cleaning routine and saved me a considerable amount of time. Its suction power is sufficient to effectively remove dust, crumbs, and pet hair without difficulty. Additionally, it navigates around furniture efficiently and rarely becomes obstructed. Another notable advantage is its relatively quiet operation compared to traditional vacuum cleaners, allowing it to be used at any time without causing disruption. It is also very user-friendly and maintains a consistently clean environment with minimal effort. Overall, I highly recommend this vacuum. It is dependable, well-constructed, and represents excellent value for its performance.

Broke after 2 months.

Color: Bright White

This is 2 months old, it worked fantastic for 2 months It cleaned everything knew where it was going found its way home every time. Now it won't move it's turned on The brushes are spinning there's no way to turn it off and the button isn't working to power it down I have to let it sit and run for hours on its back so that it will die because there is no way to open it that I can find and there's no power off switch other than the one on the top which is not responding to me touching it.

Great for hard surfaces.

Color: Bright White, Color: Bright White

I love this vacuum for my hard floors. But make sure you check the clearance on all of your furniture as it gets stuck under my stuff easily. I am not a fan of the “mop” feature. It just drags around a wet swiffer pad. So obviously it doesn’t mop much. But for hard floors, this was a great purchase for the price! The quality of the vacuum is great! Even the packaging is nice. But I will say you need to look for the bigger filters as the K5 filters do not fit. Also, the app on your phone needs to be on the same WiFi as the vacuum or it disconnects and you need to reconnect it. I need to empty the collection bin every day, but I also have 4 dogs. I would definitely recommend this to someone with hard floors.
