Narwal S20 Pro Cordless Wet Dry Vacuum Cleaner Review

The Narwal S20 Pro is the mop I wanted to love. It's one of the lightest, most maneuverable wet/dry mops I've pushed — self-propelling wheels, a low center of gravity, and a kick-to-start that means you never have to plant a foot on it. The design and feature set are genuinely nice. But when I put it on a real big-mess test, it failed the white-glove check on its own auto setting and only got clean once I switched to Max and held the trigger the whole time. Pair that with leaking at rest and a heated-plate drying step that left the pad feeling wet, and it's a Skip It for now. Here's how it held up.

What's in the Box and First Setup

The S20 Pro is a cordless, lie-flat (180°) wet/dry mop with a silver-ion clean tank (about 790 ml) and a dirty tank (about 670 ml), a replaceable brush roller, and a dock that charges it and runs a hands-free self-clean. It's loaded with features for the money: five cleaning modes (Smart, Suction, Turbo, Quiet, and Max), AI DirtSense that auto-doses solution and suction, an LCD screen with voice prompts, and a solution indicator that reads white when empty and orange when full. There's also a trigger you can hold to lay down extra solution for big stains. It ships with a spare roller, filter, and brush in the box.

Cleaning Performance: What It Actually Picks Up

The Big Mess Test

I threw a genuinely nasty mess at it — dirt, debris, paw prints, and hair pressed into the floor. In Smart mode it auto-dosed the solution and the dirt-detect screen turned yellow to boost power on its own, which is exactly what you want a smart mop to do. The problem was the result: the first full pass failed the white-glove test, leaving streaks and a bit of dirt behind. I called it honestly on camera — I thought I'd do better. A second pass in Max mode with the trigger held the whole time came out much better. So it can clean a heavy mess, but it needs maximum power and manual help to get there, and it underdelivered on the auto setting most people will actually use.

Stains

Same story as the big mess: it came clean only when I ran Max enhancement with the trigger held down. On the lighter auto settings it left too much behind for my liking. Treat it as a mop that will handle stains if you're willing to run it hard, not one that quietly takes care of them for you.

Hair and Pet

This was a bright spot. The mess I ran had long hair mixed in, and the dual-comb tangle-free brush plus strong suction channeled the hair and debris straight into the waste trap. The trap caught all of it and was easy to dump into the trash, and I didn't see tangling on the roller. I didn't do an isolated hair-only test on camera, but on a real mixed mess the trap clearly did its job.

Ease of Use — Where It Shines

This is the whole reason to look at the S20 Pro. At about 9.4 pounds it's genuinely light — like holding two soda cans — and the self-propelling wheels and low center of gravity make it glide across the floor. You kick it over-center to start, so you never have to hold it down with a foot, and travel rollers let you wheel it around when you're moving between rooms. Five modes give you room to dial it in, the trigger adds solution on demand, and the LCD screen with voice prompts and the white/orange solution indicator make it easy to read at a glance. It also comes apart easily for service. If ergonomics were the only category, this would be near the top of the pile.

Maintenance Reality

After you're done, the base runs a 149°F hot-water self-wash of the roller and then dries the pad with a heated plate. Here's the catch: there's no hot air. I felt no airflow, just a warm plate, and the pad felt wet again mid-cycle, which struck me as a weird process. The waste box separates solids so you can drop them in the trash, and you pour out the dirty water. The filter is reusable but has to dry fully before it goes back in, and there's no built-in tray to air-dry any of the removed parts. Two things you have to stay on top of: it leaks and drips where you set it down near the brush roller, and you need to empty and rinse the dirty tank every single use or the plastic starts to trap odor — I found that out the hard way.

Battery and Runtime

Narwal rates it at up to 60 minutes of run time in the lower-power mode, with a recharge around three and a half hours. The runtime drops on Turbo and Max, which is exactly where you'll be running it to clean a heavy mess. I didn't time a full clean, so treat runtime as plenty for a normal session but shorter than the headline number if you lean on Max the way I had to.

Is It Worth It?

At its price the ergonomics are the best part of the roundup, and if it cleaned on auto the way it pushes, it'd be an easy recommendation. But needing Max plus the trigger to get a big mess clean, leaking at rest, and the half-baked heated-plate drying add up to a Skip It for now. If it mostly cleaned light everyday spills and lived at a much lower price, it'd be a different conversation — but as tested, I'd wait and see how it stacks up against the newer rivals I'm testing next.
