The Narwal Flow uses a FlowWash rolling track mop that Narwal says is rinsed with 113°F water as it cleans. This page is based on manufacturer-published specifications and manuals plus aggregated owner reviews; we did not test the products ourselves.
Our verdict
If mopping quality on hard floors matters more to you than the lowest height, the Flow’s rinsed track mop is its standout. For very low furniture, the 3.14 in Roborock Saros models are slimmer.
