OKP is a company specialising in robot vacuum and related household products. The OKP K5 Robot Vacuum Cleaner is a robot vacuum cleaner with a super strong 2500 Pa powerful suction. Equipped with anti-collision and anti-drop sensors, and with a run time of two hours, it can be left to its own devices to clean your floors while you’re busy elsewhere. Using the OKP App you can even set it to run while you’re out of the house.
What’s more, the K5 robot is quiet, it’s stylish, and best of all it’s priced very competitively with a full RRP of £189.99 and is currently available to buy from Amazon for £100.
This is the fourth robot vacuum cleaner I have tried: I’ve reviewed both the Eufy Robovac which at four years old is still going strong (although needs rescuing a lot!) and the talking MOOSOO MT-710 (slightly less powerful but does the job for low traffic areas), and most recently the OKP K2 robot vacuum; a similar version to the K5.
The more powerful OKP K5 robot vacuum is now available at a similar price to the K2, but it is a better option? As we already have a robot vacuum cleaner on each floor, does the K5 have what it takes to become a member of the household? And which one will we be passing on?
OKP K5 Robot Vacuum Cleaner Review
The OKP K5 Robot Vacuum Cleaner is similar to the other robot vacuums in appearance – i.e. it’s round with spinning brushes.
It’s the same size as the OKP K2; a bit smaller in width than the others and as I’ve no doubt you’ve noticed it’s white, rather than black or blue which might sway you depending on your decor. Height wise, there isn’t a lot of difference, although it’s a bit lighter (3.16kg) than the other robot vacuums apart from the K2.
It does not have a brush like the Eufy or MOOSOO robot vacuums but simply two spinning brushes and an inlet for dust and debris.
Like the K2, it features a 0.5l dust box accessed via the top, rather than turning the robot upside down to empty it, which is a great design and makes the whole thing much easier as you don’t have to flip it over to empty it. Having used the K2 robot regularly, this is a feature I have learned to really appreciate.
The on/off button is also located there, at the top on the inside, rather than on the bottom.
What’s in the box?
In the box with the OKP K5 robot vacuum, you get a spare filter and four brushes (two for use and two spares). There is also a white matching charging port and, of course, some instructions.
How did the OKP K5 Robot Vacuum Cleaner perform?
On its very first full charge, which should take around five hours but I left overnight, the robot cleaned for around 1hr 40 before returning to the charging port (albeit the wrong one; clearly the two chargers for the K2 and the K5 are cross compatible which is useful to know).
The K2 robot which has been in regular use for four months lasted 15 minutes less before returning so I have good faith that the battery performance won’t degrade quickly.
The instructions state that the OKP K5 robot vacuum has a two hour run time so this is about right for a normal clean; if using the ‘powerful’ mode I wouldn’t expect it to last that long. It’s certainly enough to get a floor of a house done on a daily basis.
The vacuum cleaner slots on really easily to the port (not always the case with some robots which need a lot of wiggling!) and then recharges itself automatically for the next use. Bear in mind that you will need to empty the dust box, I’d say every second or third clean at a minimum if not after every use, depending on what’s on the floors.
It was able to go up and down off the rugs and it only beeped once for attention while it was on, when it came a cropper with a clothes airer and I had to rescue it. Aside from that, it dealt with furniture (sofa, chest of drawers, bedside tables etc) and changes between different flooring surfaces, including carpet and vinyl flooring, with no problems.
The OKP robots are eqipped with self-proclaimed “Freemove 3.0 Intelligent Obstacle Avoidance” with infrared sensors installed in the front of the robot rather than a bumper, so it won’t go around colliding into furniture and walls. It’s very clever to watch and it also means it’s very quiet as it doesn’t bump into anything.
It has drop sensors so it won’t plummet down the stairs, which is quite important! I put it in my office for a while to see how it would deal with cables and this time it didn’t get caught which was surprising. The Eufy model robot is particularly bad for this and will hunt down and get stuck in any cable, but then it has a brush underneath which the brushless OKP models do not. Given how much time I spend cutting hair out of the brush, I can’t say whether this is a good or a bad thing.
It’s quiet – noticeably quieter than older models of robot vacuum cleaner – and has a quiet mode which can be activated on the app if you’re trying to clean and concentrate at the same time.
Suction on the OKP K5 vacuum cleaner
Despite costing under £100 currently on Amazon, the OKP K5 Robot Vacuum Cleaner is still extremely effective with 2500pa super-strong suction. The robot sucks up all manner of dust, carpet fluff, debris and hair, and it is claimed that it will even get pet hair off the floor, although we don’t have pets in this house to test it out yet. Maybe one day!
After the first vacuum there was a large amount debris in the dust box however there was room for more and I imagine that it would compact down. I’d estimate you could run the robot cleaner twice or three times without having to empty it out as this is not a self-emptying model, although obviously if you have long periods between cleaning, or pets, you might have to empty more regularly.
As mentioned, emptying the dust box is a lot easier than in some other models of robot vacuum as it’s accessible via the top rather than having to turn the machine upside down. It comes out easily with one hand, opens with a clip to get rid of the dirt in the bin, and slots back in smoothly without dropping its contents everywhere.
The OKP App
Like most modern robot vacuums, you can press the button on the top to start and stop the clean, but OKP also have an app that you can download to manage your vacuum cleaner remotely.
It takes just a few minutes to pair the vacuum to your wifi by downloading the app and following the instructions. In the app, you can do things like start and stop the vacuum, choose the cleaning mode (standard, powerful or quiet), select the area that you want cleaned (the whole area, along the edges or spot focus) and find it if it’s gone missing under some furniture. You can also see how long it cleans for and watch where it goes, if you’re so inclined. It will also tell you if it has run into trouble and needs assistance, and what the battery level is like.
It’s a very simple app without too many confusing features. You can set it up with the app to work with Google or Alexa so you can start it with voice commands, although I’ve not done this because the kids would probably think it was hilarious to release the vacuums and I imagine it would get annoying quickly.
How does the OKP K5 robot vacuum compare to other models?
Of the four robot vacuums that I own, the OKP K5 robot is joint cheapest (currently £109.99 on Amazon with additional discounts available) and smallest, but at 2500 Pa it has the strongest suction. However, it doesn’t have the brush that presumably makes the other models more expensive, picking up hair etc that may be embedded in the carpet.
As with the K2 robot vacuum, it is really easy to use and fairly quiet. The battery lasts a good amount of time, it’s small and charges discreetly, and I haven’t had any problems with it finding its way back to the charger. Although the dust box is very slightly smaller than on the Eufy (0.5l compared to 0.6l), the ease of emptying this via the top makes up for it.
But how does it compare to the others?
I put my robot vacuum cleaner herd to the test.
It was a very quick and unscientific comparison I’m afraid. All robots were fully charged and had their dustboxes cleaned and weighed before, and weighed again afterwards. I monitored the number of times they got stuck/beeped, and how long they cleaned for.
| Vacuum | Length of clean | Weight start | Weight end | Grams picked up | Needed help? | Back to charge? |
| K2 (no brush) | 2hr | 161 | 161 | 0 | No | Yes |
| K5 (no brush) | 1hr37 | 159 | 161 | 2 | No | Yes |
| Eufy (brush) | 1h15 | 267 | 271 | 4 | Yes, beeped x 2 | Yes |
| Moosoo (brush) | 1hr56 | 302 | 307 | 5 | Yes, got stuck | No |
As dust doesn’t weigh very much, I took pictures of what was in each dustbox at the end of the allotted time. Evidently they made it to different areas of the house and it looks like the larger brushed vacuums made it to the dirty areas (by doors where things are being tracked in and out) and cleaned up before the others had a chance to get there.
Surprisingly, the K5 on this occasion lasted less time than the K2, however it found its way back to charge more quickly than the others. It picked up some dust and debris, but not as much as the larger vacuums. However, these both had more issues and if left to their own devices would have stopped working and not found their way back to the charging station. For reliability, the OKP robots score very highly.
Verdict on the OKP K5 robot vacuum
I like the OKP K5 robot vacuum a lot. The colour is nice, although it does show up any dust/debris which happens to fall onto it. It’s small and discreet and it does a good enough job of cleaning, although does not pick up as much as a more expensive, brushed vacuum might. Although it didn’t pick up as much as the other robots when tested, on smaller carpeted areas (such as in the bedroom) it definitely filled the box up quicker.
I was surprised that it didn’t last as long as the K2 on the second run. Despite the K5 having better suction and runtime, there doesn’t seem to be a lot in it, to be honest, in terms of performance between the two – so if asked, I would opt for whichever colour I preferred best and/or whichever was cheapest at the time. They are both great little gadgets.
The only downside in my mind is that the charging station lights up, making it unsuitable for use in a bedroom if you prefer to have no light at night. Once it is fully charged, the on/off button goes off completely on these models making the K2 a good option for a bedroom, but for the K5 you’d have to stick something over it, which is a shame!
