I test vacuums for a living: This is one of the best I’ve tried, and it's $75 — that's 50% off — with Yahoo's exclusive code
'Constantly surprised at how much hair it gets’: Nab one for Amazon’s lowest price ever.
Robot vacs let you put your cleaning on autopilot, saving you loads of time and energy. Having tested my fair share as Yahoo Life’s resident home editor, I can also attest that they can, unfortunately, be clunky, clumsy and tricky to navigate — not to mention pricey. Enter the Okp K2 Robot Vacuum, a favorite among Amazon reviewers, Yahoo Life readers (and now yours truly!) for its sleek, intuitive design and effectiveness that rivals some of the biggest brands in the biz.
My only regret is that I didn’t try it sooner: The K2 has saved me so much hassle and added hours back into my week. Read on for what makes it one of my favorite robot vacs to date and — here's where it gets exciting — score one for only $75, its lowest Amazon price yet, when you apply our exclusive discount code 50YAHOO50 at checkout through May 7.
More than 8,000 Amazon reviewers agree — this lightweight yet powerful robot vac makes cleaning a breeze.
What makes the OKP K2 Robot Vacuum so great
After reading some recent hype (more on that later) about the Okp Life K2 Robot Vacuum Cleaner, I decided to take it for a spin. It arrives with everything you need, including AAA batteries and an extra air filter, and it charges up quickly (though to get a full cleaning cycle, the brand recommends four to five hours of charging).
You can schedule sweeps remotely
Setup and start couldn’t be easier. Simply tap the Start button (or hold it for three seconds to enter Wi-Fi pairing mode) for a straightforward setup. The Okp also works with voice activation via Alexa or Google Assistant (what I use), and it can be controlled via smartphone apps for iOS or Android. The app allows for scheduled sweeps, which has proven super convenient when I'm late getting home and expecting company. I use the iPhone version of the app and it’s been user-friendly — syncing is a breeze and scheduling has been a life-saver.
It's quiet, yet mighty
Having a vacuum that can clean under my feet while I'm working from home or napping on my couch is a non-negotiable for me. The Okp K2 has proven to be quiet enough to get the job done without rousing me from sleep and without letting my boss know that Rosie the Robot is cleaning around me during video chats.
Despite being so quiet, it packs 1800Pa of power and a HEPA filter for effectively picking up human and pet hair, dirt and debris (bonus: improved air quality). It's also incredibly versatile, designed for hardwood floors and rugs, with four different settings for added customization. The ability to detail edges or spot-treat is especially helpful when I'm in a rush or an area requires extra attention.
It's slim and sleek (ideal for small spaces)
Unlike some other clunkier robot vacs I've tried, the Okp K2 Robot Vac is also incredibly sleek. It has a minimalist design and a shallow body that measures less than 3 inches high (competitors typically hover around 4 inches).
That slim profile has proven essential for cleaning under sofas, consoles and dressers — or any other areas that are difficult to reach — giving those zones a far more thorough clean. No more bending over to get under furniture your robot vac may have missed.
And you don’t have to worry about the K2 bashing into furniture or tumbling down the stairs and breaking, at least based on my experience, thanks to its anti-drop sensing technology.
It's powerful
I've been getting the promised 100 minutes per charge (give or take) before the K2 heads back to its dock for charging. I can usually sneak in two to three vacuum cycles before emptying the generous but slim dust collection bin. Judging by how full the bin is and how pristine my floors look when finished, I'd say the K2 vacuum is highly effective at doing its thing. It's a solid (and, with our exclusive discount, much less costly) bet for someone who has yet to experience the life-altering convenience of a robot vac — or is looking to add an extra-slim, quiet option to their collection.
What customers are saying
By now, you can tell that I'm a K2 devotee — and I'm in good company. The Okp K2 Robot Vacuum is endorsed by over 8,000 customers who rely on the robot vac for keeping both rugs and hardwood floors dirt- and lint-free:
"One of the best," exclaimed one reviewer. "I just bought our third K2 vacuum … the first two were bought in 2021 and 2022 and are still working fine despite daily use. We have mostly hardwood floors and [the K2s] are quiet and have good enough suction to keep our house clean with two dogs and three cats. The app is easy to use and you can name your vacuums and set different schedules. It tells you the charge on each vacuum and has a find feature if your vacuum gets lost. You can set different suction powers [and cleaning modes] on the app as well."
"I am so impressed with it," added another shopper who also said the K2 rivaled their higher-end Shark. "It makes vacuuming a once-per-day job instead of an ongoing struggle. I'm constantly surprised at how much hair it gets and how great my hard floors look. [The vac] came with replacements for each sweeping arm and the filter. Emptying it is simple and cleaning the arms is as easy as pulling them off, removing whatever is caught, and snapping the arms back on."
"Glad I bought one," wrote a third. "... I thought it would get trapped in the dining room with the chair and table legs — and nope, it kept going once it got a free path. It ran for about an hour and a half." The reviewer said they had to help the robot vac find its way back to the charging station in this case but that the dust bin was full, indicating it had done a "good job." They added: "All in all, [the vac is] worth the cost and, even without the app, it does what it's supposed to do."
