NARWAL S20 Pro
Ranked #4 in Best Wet Dry Vacuum Mops
NARWAL S20 Pro
1 source$324as of Oct 17

The NARWAL S20 Pro is a cordless, self-propelled vacuum mop for hard floors, weighing 9.41 lb with a 0.79-litre clean-water tank and a self-cleaning, hot-air-drying dock. Vacuum Wars measured top-tier mopping, 151 points in its stain test and a combined score of 175 that tied for first, while noting low usable suction and a smaller-than-average tank. Business Insider found it picked up everything from flour to syrup in a single forward pass, cleaned flush to walls and left the brush roll dry after its self-clean cycle, but did a poor job when pulled backwards. It suits buyers who want mopping results close to flagship machines in a lighter package; anyone who cleans with long back-and-forth strokes or has rugs should look elsewhere.

Strengths
  • — Tied first in Vacuum Wars' combined mopping test with 175 points, against a 138 average
  • — Cleans flush to walls, with no dry gap left at the edge in Business Insider's test
  • — Self-cleaning and hot-air drying left the brush roll fully dry
Watch-outs
  • — Cleans poorly in reverse; coffee and cereal caught behind the wheels
  • — Usable suction measured 0.55 kPa, well below the 1 kPa category average
  • — No LED headlight on the floor head to show up debris in dim areas

Tineco Floor One S9 Artist Steam
1 source$749as of Oct 17

The Tineco Floor One S9 Artist Steam is a cordless, self-propelled vacuum mop with a steam mode, a self-cleaning dock and a 0.88-litre clean-water tank. Vacuum Wars found it among the strongest hard floor cleaners it has measured, with 151 points in its dried-on stain test, 0.4 g of water left behind and a 75-minute battery run. Popular Science found it handled pet hair, spills and an old berry stain on linoleum, ran far more quietly than a full-size vacuum and never tangled the roller. It suits owners of large hard-floored homes, pets included, who want vacuuming, mopping and steam in one machine; anyone who struggles with a 13.5 lb machine or mainly has carpet should look elsewhere.

Strengths
  • — Scored 151 in Vacuum Wars' dried-on stain test, against a 140-point average
  • — Left 0.4 g of water on the floor in Vacuum Wars' test, against a 1 g average
  • — Ran 75 minutes in Vacuum Wars' battery test, against a 35-minute category average
Watch-outs
  • — Heavy at 6,148 g (13.5 lb), the second-heaviest model Vacuum Wars compared
  • — 0.88-litre water tank is smaller than the 1-litre category average
  • — Not built for deep carpet cleaning; it handles light rug passes only

How they stack up

NARWAL S20 Pro

Listed at $323.99, the S20 Pro is a lighter, lower-priced alternative to the Bissell CrossWave Edge, the DREAME H12 PRO and the Tineco Floor ONE i5 Stretch, weighing 9.41 lb with a self-propelled head. Its measured strengths are mopping and edge cleaning; buyers who clean in long back-and-forth strokes should weigh its weak reverse pickup.

Tineco Floor One S9 Artist Steam

At its $749 listing the S9 Artist Steam is a flagship alternative to the Bissell CrossWave Edge, the DREAME H12 PRO and Tineco's own Floor ONE i5 Stretch, distinguished by a dedicated steam mode and a 75-minute measured runtime. Its 13.5 lb weight and 0.88-litre tank are the plain costs of that steam system.
