OKP K3 Robot Vacuum

No, because there's no brushroll to wrap. The K3 picks up cat and dog hair and long human hair, and the odd clump that clogs the inlet pulls out easily by hand. That makes it a low-fuss choice for a shedding pet on hard floors.

Yes, it can. Its sensors miss low objects, so the K3 tries to swallow cords, pushes light things around and can get stuck under chairs. Picking up the floor before each run is the fix, and it's worth doing every time in a room with cables near the floor.

It's mixed. Scheduling through the app works without trouble for some, but others find it loses connection, lacks options for the cleaning path, or has features they can't get working. The K3 only joins 2.4GHz Wi-Fi, and Alexa or Google Assistant can start it too.

A room or two. The rated runtime is 120 minutes, but cleaning time per charge often lands around 20 to 60 minutes, enough for a bedroom or a living room and kitchen. In a larger space one charge may not finish the job, though the K3 heads back to its dock when it's low.

Hard floors suit it better. On hardwood and vinyl the K3 picks up crumbs, sand and dust well. Rugs and mats split opinion: it copes with a thick mat in one home, while carpet pickup is weaker in another. With 2000 Pa of suction, treat rugs as a bonus.

Reliably, yes. When it's done the K3 heads back to its base on its own, though it sometimes wanders for a while before finding it. Keeping the area around the dock clear helps too, since low objects are what trip up its sensors.
