Tineco Floor One S9 Master Cordless Wet Dry Vacuum Cleaner and Mop

This flagship model in Tineco's Floor One S9 line-up currently has tracked UK prices of £537.10 to £699. Treat current pricing as unsettled until confirmed with a retailer, and confirm the current figure before buying. Whichever you pay, the Master sits above the S9 Artist and Artist Pro variants, justified by features like ThermoBlast hot water mopping, a self-cleaning FlashDry/SilentDry dock and a wide 30-65 minute runtime, so weigh the premium against those extras rather than comparing price alone.

This isn't confirmed. Tineco's documentation refers only to a generic 'dry filter' for this model without stating HEPA certification, so this should be checked directly with Tineco if it matters to you. Suction power in watts is similarly unspecified in available sourcing, leaving two of the more commonly compared specs unresolved for the Master. What is confirmed is the rest of the airflow and cleaning system: a 23kPa max sealed suction figure, an iLoop smart dirt sensor that adjusts suction and water flow automatically, and a self-cleaning dock that rinses the mop head with 85°C hot water rather than filtering air. Buyers with allergies or asthma who specifically need certified HEPA filtration should treat this as an open question rather than assume it's included.

No, it has a self-cleaning dock that rinses and dries the mop roller with hot water and hot air, but it isn't an automatic dust-bin emptying station. The dock runs a 5-minute FlashDry mode or a 40-minute SilentDry mode, using 85°C water to clean the 720° rotating anti-tangle brush roller, which handles mop maintenance rather than waste disposal. That means the 0.7-0.72L dirty water tank still needs emptying by hand after each session, alongside the separate 0.85L clean water tank, which needs refilling. This positions the Master similarly to other models in Tineco's Floor One S9 range, none of which offer full automatic bin emptying despite the Master's flagship status and features like ThermoBlast hot water mopping and app connectivity via the Tineco iLoop app.

Sourced data lists it as suited to hard floors, such as hardwood and tile, rather than carpeted surfaces. That fits its design as a wet-and-dry vacuum-and-mop combo built around ThermoBlast continuous hot water mopping, heated to around 52°C, and a StreakFree Scraper intended to leave floors dry to the touch, both features aimed squarely at hard flooring rather than carpet pile. The self-cleaning dock and 720° rotating anti-tangle brush roller are likewise built to manage a wet mop head, not dry carpet fibres. If your home includes carpeted rooms as well as hard floors, you'd need a separate vacuum for those areas, or it's worth checking other Tineco vacuum cleaners or browsing other wet and dry vacuums for a model that covers both surface types.

Runtime is listed as 30 to 65 minutes depending on the mode and power draw used, powered by a 25.2V, 4Ah lithium-ion battery, with a charge time of roughly 4.5 hours. That wide runtime range reflects the Master's multiple modes, including the iLoop smart dirt sensor's automatic suction adjustment and the ThermoBlast hot water mopping function, both of which affect how quickly the battery drains. Runtime is paired with a 0.85L clean water tank and 0.7-0.72L dirty water tank, both large enough to support longer cleaning sessions without a refill. The self-cleaning dock, with its 5-minute FlashDry or 40-minute SilentDry cycle, only recharges the battery and cleans the mop head between uses; it doesn't extend runtime or self-empty the dirty water tank.
