How well does the Narwal Flow clean carpets and hard floors?

The Narwal Flow performed well on both hard floors and carpets. In deep clean tests, it scored an impressive 83% on carpets, significantly higher than the 76% average, and also excelled at picking up flattened pet hair. While generally effective on hard floors, it sometimes required multiple passes for very fine debris like coffee.

Can the Narwal Flow handle wet spills and deep stains?

Yes, the Narwal Flow excels at mopping, ranking among the top seven overall. Its new roller-style mop can pick up small wet liquid spills, unlike spinning mops that spread them. It also achieved significantly above-average stain removal scores using minimal water.

What are the most significant drawbacks of the Narwal Flow?

The reviewer experienced quality control issues with the water pump requiring manual priming. The app also has minor quirks, such as defaulting to avoid carpets and lacking fine-grained control over obstacle avoidance settings, sometimes requiring cameras to be covered during mopping tests. Additionally, the detergent system requires manual adding each time.

Does the Narwal Flow prevent hair tangles on its brushes?

Yes, the Narwal Flow is designed to prevent hair tangles effectively. It features a dual side brush system that shifts shapes automatically and a main brush roll unattached at one end to channel hair. In testing, it achieved a perfect score in a 7-inch hair tangle test, a common area where other robots struggle.

How tall is the Narwal Flow and how does it navigate?

The Narwal Flow is relatively slim at 3.7 inches tall, allowing it to get under more furniture. It uses a semi-internal spinning lidar mounted in the back, which sees about 180 degrees. While this is a slight downgrade from 360-degree top-mounted lidars, it navigated efficiently in home tests, mapping quickly and avoiding getting stuck.

About this source

This video review from Vacuum Wars evaluates the Narwal Flow, a flagship robot vacuum and mop combo. The reviewer conducts a series of tests over several weeks, covering aspects such as hair tangle reduction, vacuuming performance on different surfaces, mopping effectiveness, obstacle avoidance, navigation, and battery life. The review also discusses features of its multi-functional dock and app.

Review notes

The Narwal Flow proves to be an exceptional top-tier robot vacuum, earning a strong recommendation for its comprehensive cleaning capabilities. It excelled in testing, scoring perfectly in a 7-inch hair tangle test and achieving an 83% carpet deep clean score, significantly above the 76% average. Its new roller-style mop system also delivered significantly above-average stain removal with low water usage, ranking among the top seven performing mops ever tested. However, a notable drawback was its struggle with fine debris like coffee on hard floors, often requiring multiple passes. If you prioritize outstanding mopping performance, effective hair management, and superior deep carpet cleaning, the Narwal Flow is an excellent investment. However, if flawless single-pass pickup of fine hard floor debris is a primary concern, you might find it requires a bit more effort.
