Ryobi ONE+ 18V Cordless Wet & Dry Vac (Bare Tool)

What is the Ryobi ONE+ 18V Cordless Wet & Dry Vac (RV1811-0)?

The RV1811-0 is a cordless wet-and-dry vacuum built on Ryobi's ONE+ 18V battery platform, designed to pick up both dry debris and wet spills around the home, garage or workshop. It's sold as a "bare tool" — the unit itself, with no battery or charger in the box — which is standard practice across Ryobi's ONE+ range and lets owners of other ONE+ tools reuse a battery they already have. The 11-litre tank, IPX4 rating for wet pick-up, and a blower port for clearing debris point this model more toward garage, car and DIY clean-up duty than everyday household use — worth bearing in mind if you're comparing it against a typical wet and dry vacuum built for spills in the kitchen or bathroom. The manufacturer's own use-case tags (hard-floor, tile, multi-surface) support that positioning.

Price: what we found

Ryobi's own UK site lists the RV1811-0 at £134.99, shown as in stock at time of writing. A wider check across six UK retailers puts this model as low as £119.95 (PriceRunner and an Amazon.co.uk marketplace seller), with other listings at £119.99 (ITS) and £128 (TradePoint). One outlying listing shows £249.95 — roughly double every other price found — which looks more likely to be a different bundle or a misattributed listing than the same bare-tool SKU at that price. Whichever retailer you buy from, remember the battery and charger are a separate cost on top of the vacuum itself.

Runtime and the ONE+ battery platform

Because this is a bare tool, runtime depends entirely on which ONE+ battery you pair it with. Retailer-quoted figures put runtime at roughly 12 minutes on a 2.0Ah battery and up to 31 minutes on a 5.0Ah battery; neither figure appears on Ryobi's own spec sheet for this model, so treat them as indicative rather than confirmed. The 105W power input and 115W max suction figure carry the same caveat — both come from a retailer listing rather than the manufacturer's page. If you already own a Ryobi ONE+ 18V battery from another tool, this vacuum will run on it, and RYOBI LINK compatibility means no separate charger purchase if you're already in the ecosystem. If you're starting from zero, factor a battery and charger into the total cost before comparing this price against corded or battery-included wet/dry vacs — and our guide to cordless vacuum battery life explains how amp-hour capacity translates into real-world runtime if you're choosing between the 2.0Ah and 5.0Ah options.

Filtration, capacity and features

The 11-litre tank is large for a cordless wet/dry vac, and the washable HEPA 12 filter is claimed by Ryobi to capture up to 99.5% of particles — useful for anyone doing dusty DIY clean-up, though this is a manufacturer claim rather than an independently tested figure. If you want to understand what HEPA filtration actually certifies, our guide to HEPA filters in vacuum cleaners covers it in more depth. Two-speed operation trades suction for extended runtime, a blower port reverses airflow to clear leaves or workshop debris, and a universal adaptor lets the vac connect directly to compatible power tools for dust extraction while sanding or cutting — a feature aimed at DIY/trade use rather than domestic carpet cleaning. The included extendable hose, funnel, crevice tool and dust port adapter store onboard.

Weight, noise and a dimension discrepancy

At 4.5kg without a battery fitted, this is a reasonably light wet/dry vac, but at 83dB it sits on the louder end for the category — worth knowing if you'll be using it indoors near others. On physical dimensions, sources disagree: one UK retailer lists 760 x 430 x 460mm, which reads like a boxed/packaging measurement, while another lists 460 x 285 x 273mm, closer to what you'd expect for a compact cylindrical unit like this. We've used the smaller, unit-level figure in the table above, but treat both as unconfirmed until you check with the retailer or in person.

Warranty and who this vacuum suits

Ryobi's UK site states a 3-year guarantee for this model, though standard ONE+ terms typically require online registration within 30 days of purchase to extend from a base 2-year warranty, and at least two UK retailers list only 2 years on their own product pages — confirm which applies before relying on it. Overall, the RV1811-0 suits someone already invested in Ryobi's ONE+ 18V platform who wants a garage- or workshop-capable wet/dry vac with decent tank capacity and washable HEPA filtration, without paying for a battery they don't need. It's a weaker fit if you want a plug-and-play unit straight out of the box — you're buying a body only — or if you need something built primarily for everyday carpet and household cleaning rather than DIY clean-up; in that case a cordless vacuum designed for multi-surface home cleaning may suit better.
