Today, we’re taking a close look at the Tineco S9 Artist Steam cordless wet dry vacuum. A big thanks to Tineco for sending us a sample. As always, our opinions are our own. If you’re interested in purchasing, the link is in the description.

Unboxing and Setup

The Tineco S9 Artist Steam arrives with everything you need to get started: the main unit with a snap-in handle, a charging base, a cleaning brush, an extra roller brush, a washable filter, and the product literature. Setting it up is simple. Just attach the handle, charge the vacuum, fill the tank, and you’re ready to start cleaning.

From the very first use, the S9 is a joy to operate. It’s lightweight, easy to maneuver, and glides effortlessly across floors. One of the standout features is the real-time color-changing display, which highlights the areas of your floors that are dirtiest, so you know exactly where to focus your cleaning efforts. The display is bright and easy to read, and switching between cleaning modes is quick and intuitive. Typically, we start in auto mode and switch to steam for sticky spots that need extra attention. The LED light, now included on the Steam model, is a welcome improvement over the Pro version, making it easier to see in darker corners. Combined with smooth drive technology, the vacuum feels precise and effortless to push, even around furniture.

For those who like to customize settings further, the S9 can connect to the Tineco app, though most users will find that the vacuum performs perfectly well without it.

Performance and Price

When comparing the Tineco S9 Artist Steam to other wet dry vacuums, it’s clear that this is a premium device. Having tested over 30 models, we can confidently say that the S9 is top-tier in both design and performance. Its price is higher than average, reflecting its flagship status and the inclusion of steam functionality.

While the cost may surprise some—more than double that of the S6 Stretch—the steam feature is the primary reason for the premium. If you don’t need steam, a more budget-friendly option like the S6 Stretch will still perform exceptionally well.

Performance-wise, the S9 excels. With a suction power of 22,000 Pascals, airflow of 68 FPM, and vacuum pressure of 1.91 kPa, it’s one of the most powerful wet dry vacuums we’ve tested. Noise levels sit at 78 dB, which is quiet enough to clean without distraction. Runtime is impressive at around 75 minutes in auto mode with the vacuum in a lie-flat position. This extended battery life comes courtesy of Tineco’s pouch cell technology, which increases energy density and efficiency. However, the clean water tank lasts about 50 minutes, so refills may be necessary during longer cleaning sessions. Steam mode is rated for 30 minutes, though we found about 20 minutes of practical use is realistic.

Both the clean and dirty water tanks are above average in capacity. The dirty water tank is particularly noteworthy, being the largest we’ve tested across 30 models. Larger tanks mean fewer interruptions to empty and refill, which makes the cleaning process smoother and more efficient.

Design and Features

Where the Tineco S9 Artist Steam really stands out is in its thoughtful design and user-focused features. The 180° swivel head allows it to clean under beds and couches, reaching as low as 5.1 inches, which beats most competitors. Smart dirt detection automatically adjusts suction and water flow based on the level of mess, optimizing both performance and battery life. The self-cleaning system uses hot water and air to wash and dry the roller in just five minutes, quietly and efficiently.

Edge cleaning is excellent thanks to dual-edge rollers and an anti-tangle design that prevents hair buildup, while maneuverability is further enhanced by the smooth drive technology, offering 360° directional propulsion. The LED headlight is another strong point, casting a wide, bright field of view that makes it easy to clean in low-light areas. Steam cleaning works well, though it requires a few minutes to heat up and is not a magic solution for every stubborn mess. Its greatest benefit is for households looking to reduce chemical cleaning solutions.

Areas for Improvement

Even with its many strengths, the Tineco S9 Artist Steam has a few limitations. A small wheel near the handle would make gliding in lie-flat mode smoother, rather than relying on the current rubber piece. Battery life, while long, could always be improved, and there is no dedicated tank for cleaning solutions. If you want to use steam after adding cleaning solution, you need to empty the tank first, which can be inconvenient.

User Feedback

Since its release, user reviews have been largely positive, averaging around 4.2 stars. Users praise the vacuum’s strong suction, effective self-cleaning system, premium build quality, sleek design, and impressive maneuverability. Some criticisms focus on the high price and mixed opinions on the steam feature, which some find less useful for everyday cleaning.

Final Verdict

The Tineco S9 Artist Steam is a premium, no-compromise wet dry vacuum that delivers top-tier performance, long runtime, and exceptional maneuverability. With the option to clean with steam instead of chemicals, it is a versatile solution for homes looking for both power and convenience. While the price puts it firmly in enthusiast territory, it is one of the most capable and refined wet dry vacuums available today. For households that want maximum suction, advanced features, and thoughtful design, the S9 is hard to beat. Those who don’t need steam can still find excellent performance in more affordable alternatives, but for those who want the full premium experience, the Tineco S9 Artist Steam is an outstanding choice.
