In August 2026, Tineco introduced its most advanced floor washer yet — the Tineco Floor One Station S9 Scientist Pro Wet and Dry Vacuum. This high-powered device offers suction strength of up to 25,000 Pa, making it one of the strongest wet-dry vacuums available. It can pick up fine particles like flour in one pass and larger debris like 8–12 leaves in under a minute. Its lie-flat design allows it to reach under furniture, while its side edge cleaning feature can clean along the front of the vacuum, reaching up to one-half to one-eighth of an inch. The battery lasts between 65–75 minutes in Auto mode and up to 100 minutes in Quiet mode, making it suitable for cleaning most homes in a single session. The S9 Scientist Pro includes four cleaning modes, such as a dirt detection feature that automatically adjusts suction based on the amount of debris. It also has a HydroBurst sprayer for handling tough stains and uses hot water to clean the floor while continuously washing the brushroll. The brushroll presses firmly against the floor for a thorough clean and features a streak-free scraper when the vacuum is reversed. The most notable upgrade is the Smart Refresh Station, which automatically refills the vacuum with cleaning solution and clean water from a 5-liter tank. This base uses hot water and hot air to clean and maintain the brushroll, reducing the need for manual cleaning. Priced at $1,199 (approximately £880 or AU$1,660), the S9 Scientist Pro is Tineco’s most expensive model and falls into the premium price range. It is available through Tineco’s official website as well as major retailers like Amazon and Walmart. A more affordable alternative is the Tineco Floor One S9 Artist Pro, which usually costs $849 but is currently discounted to $599 and offers similar cleaning capabilities. The S9 Scientist Pro has a 25,000 Pa suction power, dimensions of 9.5 x 10.25 x 43 inches, and includes a 0.85-liter tank on the unit and a 5-liter clean water tank on the base, with a 0.72-liter dirty water tank. It also features a HEPA filter, up to 100 minutes of battery life, and a 3–4 hour recharge time. The unit comes with a brush for cleaning the dirty water tank. The design of the S9 Scientist Pro includes an 180-degree lie-flat feature for accessing hard-to-reach areas, four cleaning modes, and a solution sprayer for tough stains. It also has a self-cleaning base that automatically refills with clean water. While the vacuum head is large, it can still reach under beds and sofas. A streak-free scraper lifts when the vacuum is pushed forward and drops when pulled back, and a built-in headlight helps illuminate dark spaces. A comb and scraper near the brushroll help prevent hair and debris from tangling. The performance of the S9 Scientist Pro is impressive, capable of picking up both fine and large debris in a single pass. Its suction power is strong enough to quickly remove dried leaves, and the dirt detection system can identify even small amounts of dust. The headlight is especially useful for finding debris in dark areas. However, the bulky head can make it difficult to clean under cabinet overhangs, which may be a limitation for some users. The battery life is more than sufficient for most homes, with a runtime of 65–73 minutes in Auto mode. It can clean a 1,600-square-foot home in about 30 minutes and still have 50% of the battery remaining. While the S9 Scientist Pro is a great option for those with larger homes who want to clean on a single charge, it may not be ideal for those with limited space or a tighter budget. It is best suited for homes with hardwood, laminate, stone, or tiled floors and is not recommended for homes with a lot of carpets.
