Tineco Floor One S9 Master Wet & Dry Vacuum — Prices & Offers

Tracked UK listings for the Tineco Floor One S9 Master currently span £537.10 to £699.00, based on four retailers checked on 13 September 2026. That's a wide spread for the same machine, and the gap is worth understanding before you click through, because it isn't just about who happens to be cheapest on the day.

How much does the Tineco Floor One S9 Master cost in the UK?

The Tineco Floor One S9 Master Cordless Wet Dry Vacuum Cleaner and Mop price varies by retailer rather than by a single fixed RRP. In the tracked dataset, the lowest listing was £537.10 and the highest was £699.00 — a difference of over £160 for what should be the same product, same accessories, same warranty coverage (subject to the retailer's own terms). Prices on marketplaces and third-party sellers can move from week to week, so treat any figure here as a snapshot rather than a guarantee of what you'll see when you click through.

Where to buy the Tineco Floor One S9 Master (tracked retailer offers)

Retailer	Price	Stock status
eBay.co.uk	£537.10	In stock
u-buy.co.uk	£687.00	In stock
Amazon.co.uk (Amazon.co.uk-Seller)	£699.00	In stock
Tineco UK (official store)	£699.00	In stock

All four listings showed as in stock at the time of tracking. The two highest prices — Amazon.co.uk and Tineco's own UK store — match exactly at £699.00, which is a reasonable anchor for what this model is intended to sell for at full price. u-buy.co.uk sits close behind at £687.00. eBay's £537.10 listing is meaningfully cheaper than the rest, which is worth noticing but not automatically distrusting: eBay pricing reflects whichever seller currently has the lowest offer, and it can include used, refurbished, or import stock alongside new units from UK-based sellers, so it's worth reading the listing details — condition, seller location, and return policy — before assuming it's a like-for-like match with the retail price elsewhere. If you're weighing this model against other machines in the same category, a comparison tool can help you check current prices and specs side by side rather than tracking each retailer manually.

What you get for the price

At the top of its price bracket, the S9 Master is built as Tineco's flagship cordless wet-and-dry vacuum-mop. The headline numbers: 23kPa of sealed suction, up to 65 minutes of runtime from a 4.0Ah lithium-ion battery, and a 5.0kg body. Water capacity is 0.85L for clean water and 0.7–0.72L for dirty water, and the machine runs at around 78dB.

The features that separate it from a basic cordless mop-vac are mostly about automation and hygiene. The iLoop smart dirt sensor reads how dirty the floor is and adjusts suction and water flow accordingly, so you're not manually switching modes mid-clean. ThermoBlast delivers continuous hot-water mopping at up to roughly 52°C, which is intended to help lift dried-on residue rather than just pushing it around with cold water. A StreakFree Scraper is fitted to leave floors dry to the touch rather than streaked or damp. The 720° rotating brush roller is designed to resist hair and thread tangling, and a 150° wide-angle green LED headlight is there to show up dust that's easy to miss under normal room lighting.

The self-cleaning docking station is part of what you're paying for too: it rinses the brush roller with hot water and then dries it, offering both a fast 5-minute FlashDry cycle and a more thorough 40-minute SilentDry cycle using 85°C heated water and hot air, so you can choose speed or a quieter, deeper dry depending on when you're using it. In the box, alongside the dock, you also get a cleaning tool, a spare brush roller, a replacement filter, and a bottle of cleaning solution — accessories that would otherwise add to the running cost if bought separately later.

What affects the price of a cordless wet and dry vacuum-mop

Across this category generally, price differences between retailers usually come down to a handful of factors: whether the seller is the brand itself, an authorised retailer, or a third-party marketplace account; whether the unit is new, graded, or refurbished; current promotional stock levels; and whether accessories (like the docking station bundle) are included as standard or sold separately. A retailer's own delivery costs and return window can also make a slightly higher headline price better value overall than the absolute lowest number on the page.

Why the S9 Master costs more than other Tineco Floor One models

Tineco's Floor One line spans several wet-and-dry models at different price points, and the S9 Master sits at the top of that range for a reason: it currently offers the longest runtime (65 minutes) and the highest suction (23kPa) in the family, alongside ThermoBlast hot-water mopping and the StreakFree Scraper, which are not standard across the cheaper models. It's also the only model in the range combining both a fast FlashDry and a slower, more thorough SilentDry drying cycle on its dock, rather than just one drying mode. If you're not sure the S9 Master's extra features justify its position at the top of the price bracket, it's worth browsing other Tineco vacuum cleaners to see how the rest of the range compares on runtime, suction, and dock features before committing. Shoppers who are open to other brands entirely, not just other Tineco models, may also want to look across other cordless wet & dry vacuum-mops to see how this price bracket compares more broadly.

How to choose a retailer

Before buying, it's worth checking a few things regardless of which listing looks cheapest: confirm the seller name and location (a UK-based seller generally means clearer consumer rights and returns), check whether the price includes the full docking station bundle described above rather than a bare unit, and compare the stated warranty length against Tineco's own UK terms. If a listing is well below the others — as eBay's is here relative to Amazon and Tineco UK — it doesn't necessarily mean something is wrong, but it's a reasonable prompt to read the seller's feedback, item condition, and return policy before checking out.
