Is the Onson 7-in-1 worth buying?

Only for light jobs. Its 2.8-out-of-5 rating from 21 buyers and weak steam reports make it a risky pick if you need real cleaning power.

How much water does the tank hold?

12.03 fl oz. Expect to refill during larger floor jobs.

Does it need an extension cord?

Often, yes. The cord is listed at 13 inches, so most rooms need an extension cord.

Is it safe and certified?

The listing says it has no NRTL listing, so it lacks third-party safety certification. The 180-amp spec also looks wrong for a 120 V plug-in appliance.

What is the best price?

$49.39 at Walmart as of November 8, 2026, with two stores listing it new.
