Most robot vacuums with a mopping function that I've tested eventually start smearing dirt across the floor. The reason is simple: the mopping disc or roller collects enough dust and dirt to turn into a sort of rag that simply moves debris from one place to another. The Narwal Freo 20 Edge breaks this pattern thanks to its FlowWash system. Its distinguishing feature is a belt-like mopping attachment that works on the principle of a treadmill. This system constantly washes the attachment, wrings it out, and removes dirty water while the robot continues cleaning. I tested this on a dried coffee stain and ketchup marks – both were cleaned on the first pass, and more importantly, the robot didn't smear them all over the kitchen.
The manufacturer claims a suction power of 31,000 Pa, but real-world testing showed that on hard floors, the robot collects small debris and dog hair without issues. It also performed better than expected on carpets, although it reduced its speed, likely adjusting power automatically. The DualFlow Tangle-Free System deserves special mention: after three weeks of use with a shedding dog, the brush remained practically clean, without the usual hairballs requiring scissors. This is the first device that has truly come close to solving the brush tangling problem, not just delaying it.
Another detail that usually disappoints is corner cleaning. Most robots leave a thin strip of dust along the baseboards. The Freo 20 Edge is equipped with a dynamic extension of the mopping attachment, which reaches into the very corner instead of just going around it. My kitchen, with its hard-to-reach corner behind the trash can that was a perpetual dust collector, now looks immaculate.
The self-service station also lives up to expectations: it washes, dries with hot air (50°C), empties the dustbin, and cleans its tanks. In three weeks, I only had to refill the clean water and replace the dustbin. The mopping attachments came out dry and without any odors, which is a significant advantage over many competitors where damp discs can start emitting an unpleasant smell after just a couple of days.
The navigation is confident, without unnecessary fuss. The robot didn't get stuck on wires or bump into furniture. The noise level of 59 dB allows for video calls in the next room without distraction. A physical lock on the body is a nice touch for families with children.
The robot itself (34.8 x 36.3 x 9.4 cm) fits under most furniture, but the station (35.8 x 45 x 52.8 cm) requires more space. It's worth measuring the intended installation location before purchasing.
