Best Car and Workshop Vacuum Cleaners UK (2026)
A car interior needs a proper wet-and-dry vacuum, not a household one, for pulling grit out of footwells and mopping up spilled drinks. This guide is based on Auto Express's tested roundup (26 September 2025), where testers tried every machine in both wet and dry mode: timing how fast each cleared lines of rice, sugar and flour from a carpet mat, then how fast each ingested five litres of water, while also checking hose and cable length, accessories, stability and running costs.
We have not hands-on tested these products. Our picks are based on published independent tests and reviews, listed at the bottom of this page. How we pick.

Vacmaster Multi 20
Best overall
Auto Express's overall winner for its all-round ability, features and value, combining strong suction in both wet and dry testing with a useful blow function and a power tool socket for connecting sanders or saws.

Our picks in detail
Best overall
Vacmaster Multi 20
Auto Express's overall winner for its all-round ability, features and value, combining strong suction in both wet and dry testing with a useful blow function and a power tool socket for connecting sanders or saws. The 2.5m hose is long enough to reach around most cars without repositioning the unit, and testers rated it a full 5 stars.
- Capacity
- 20 litres
- Hose length
- 2.5m
- Wet and dry
- Yes
- Price guide
- £69.99 (at time of writing)
Pros
- Strong suction in both wet and dry modes
- Good value for the features included
- Blow function and power tool socket
- Long 2.5m hose
Cons
- Not the biggest capacity if you need to clean a whole garage in one go
Best for bigger jobs
Nilfisk Multi II 30T
Auto Express recorded the top suction test scores of the whole group with this larger machine, helped by a filter-vibration button that keeps performance up as the filter clogs. Its 4m hose was the longest on test, reaching right through a car or around a garage without moving the unit, making it the pick for bigger jobs, though it costs more than the Vacmaster.
- Capacity
- 30 litres
- Hose length
- 4m
- Wet and dry
- Yes
- Price guide
- £169.99 (at time of writing)
Pros
- Top suction scores on test
- Longest hose on test at 4m
- Filter-vibration button maintains performance
Cons
- Pricier than most on test
- Bulkier to store than smaller models
Best budget
Daewoo Wet & Dry Vacuum Cleaner
Auto Express was surprised by how capable this budget machine's 1,000W motor proved in testing, rating it 4.5 stars and calling it great value. Stable castors keep it planted while in use, though the 1.5m hose is on the short side and means repositioning the unit more often when cleaning around a whole car.
- Capacity
- 20 litres
- Hose length
- 1.5m
- Motor
- 1,000W
- Price guide
- £52 (at time of writing)
Pros
- Surprisingly strong suction for the price
- Great value
- Stable on castors while in use
Cons
- Short 1.5m hose needs repositioning
Best cordless
Stihl SEA 60 Cordless
Auto Express found this delivers the power of a corded machine from a battery source, at a premium price. The 36V battery manages just over 15 minutes on the high power setting and recharges in around 80 minutes, and a washable filter helps keep running costs down compared with disposable alternatives.
- Capacity
- 12 litres
- Hose length
- 2.2m
- Battery life
- 15+ minutes on high power
- Price guide
- £314 with battery and charger (at time of writing)
Pros
- Genuinely corded-level power from a battery
- Washable filter saves on running costs
- No cable to work around
Cons
- Expensive
- Limited run time on the high power setting
Best compact
Nilfisk Buddy II 12
A previous test winner from Auto Express, this compact machine rolls easily on its large wheels and includes a useful blow function for clearing debris. It scored 4 stars in the latest test; the cable and hose are on the shorter side and Auto Express notes the consumables cost more than some rivals, but it remains an easy-to-store option for smaller jobs.
- Capacity
- 12 litres
- Hose length
- 1.9m
- Wet and dry
- Yes
- Price guide
- £64.99 (at time of writing)
Pros
- Compact and easy to store
- Large wheels for manoeuvrability
- Blow function included
Cons
- Shorter cable and hose than larger rivals
- Consumables are pricier than some competitors
Buying guide
Why use a wet and dry vacuum instead of a normal one?
Auto Express tested every machine here in both dry mode (rice, sugar and flour) and wet mode (five litres of water), something a standard household vacuum isn't built to handle safely. That makes a wet and dry vacuum the right choice for car interiors, where spilled drinks and muddy footwells are common, as well as garages and workshops.
Corded or cordless?
A corded machine like the Vacmaster Multi 20 or Nilfisk Multi II 30T gives unlimited run time and, in testing, the strongest suction. A cordless option like the Stihl SEA 60 is more convenient for quick jobs away from a socket, but Auto Express found it's limited to around 15 minutes on its most powerful setting before needing a recharge.
How much does hose length matter?
A longer hose lets you reach right through a car or around a garage without moving the unit itself. Auto Express found this varied hugely on test, from 1.4m up to the Nilfisk Multi II 30T's 4m, so it's worth checking if you plan to clean larger vehicles or awkward spaces.
What size capacity do I need?
For occasional car interior cleaning, a smaller 10-12L tank like the Nilfisk Buddy II 12 is easy to store and enough for the job. For garage or workshop use, or cleaning multiple cars, a larger 20-30L tank like the Vacmaster or Nilfisk Multi II 30T means emptying it less often.
