Kärcher sells two very different machines under one name. The WD 2 Plus at £61.00 is a 12-litre plastic wet and dry vacuum with 2,664 ratings. The WD 2 Plus at £66.44 is a 15-litre stainless-steel model with 24 ratings. So £5.44 buys three extra litres and 111 times less review history to judge it by. The cheaper listing also contradicts itself: it states 12 litres of capacity beside item dimensions of 13.7 x 12.9 x 14.9 cm, and quotes suction as "180 Angstrom" — a unit for measuring atoms, not vacuum power.
We ranked nine of the best wet and dry vacuum models on Amazon on three things: how many buyers have actually rated them, whether the advertised numbers agree with each other, and what each machine is built to do. Price alone ranks nothing here. A listing with 2,664 ratings tells you more than a spec sheet, and a spec sheet that disagrees with itself tells you something too. Whether you want a workshop extractor or a wet and dry hoover for the kitchen, the numbers below are the ones to check first.
Vacmaster Multi 20 Wet and Dry Vacuum, 20L
Top of the ranking because it pairs the second-largest review base here with a 20-litre tank and a 1740W power take-off socket.
Advantages
- 2,539 ratings at 4.5 stars, with 72% of them five-star
- 1740W power take-off socket runs a power tool and the vacuum together
- 20-litre tank works bagged for fine dust or bagless for liquids and rubble
- 75.5 dB is the quietest figure among the corded tank machines here
- Blower port, 4m cord and 2.5m hose all included
Disadvantages
- Spec table says Portable: No while the bullet describes it as light and compact
- One power level only, with no variable suction
- 25cm cleaning path is narrow for large floor areas
- 4% of its ratings are one-star
First place goes to the machine with both the ratings and the spec sheet behind it. The Multi 20 holds 20 litres, runs a 200 air watt bypass motor, and carries 2,539 ratings at 4.5 stars. That is a deep review base for a wet and dry vacuum at this price, with 72% of those ratings at five stars.
In practice, the number that changes how you work is 1740W. That is the power take-off socket, so a sander or drill plugs into the vacuum and the tool's own switch starts the extraction. You get a 4m cord, a 2.5m hose and a 25cm cleaning path, plus a blower port on the exhaust. It runs bagged for fine dust or bagless for rubble and liquids, which means one machine covers both jobs.
The catch sits in the spec table. It lists Portable as No while the product bullet calls it light and compact — at 5.2kg on four wheels, this is a floor machine, not a carry-around. It also has a single power level, so there is no dialling the suction down for curtains. Buy it for a garage, workshop or car; skip it if you need to carry a vacuum up a ladder.
Kärcher WD 2 Plus Wet and Dry Vacuum Cleaner, 12L
Second on the strength of 2,664 ratings at 4.6 stars and the lowest price here at £61.00 — despite a spec sheet that contradicts itself.
Advantages
- 2,664 ratings at 4.6 stars, the largest review base in this ranking
- £61.00 makes it the cheapest machine here
- 4.25kg on four wheels — the lightest in the list
- Cartridge filter handles wet and dry work without a swap
- Ships with floor and crevice nozzle, two tubes, hose and a filter bag
Disadvantages
- States 12 litres of capacity beside dimensions of 13.7 x 12.9 x 14.9 cm
- Suction quoted as "180 Angstrom", a unit for atomic scale, next to a 180AW claim
- 79.2 dB is the loudest of the small corded machines here
- Control method listed as App on a corded push-button machine
The 12-litre Kärcher takes second because of the review base, not the tank. It carries 2,664 ratings at 4.6 stars, more than any other machine in this ranking, and at £61.00 it is the cheapest. That is a lot of buyer history for a small wet and dry vacuum cleaner.
In practice it is the lightest machine here at 4.25kg, on four wheels, with a cartridge filter that does not need swapping between wet and dry work. The box includes a floor and crevice nozzle, two suction tubes, a hose, a paper filter bag and the cartridge filter. Noise is quoted at 79.2 dB, the loudest of the small corded machines in this list.
The catch is that the listing argues with itself. It states 12 litres of capacity right beside item dimensions of 13.7 x 12.9 x 14.9 cm. Suction is given as "180 Angstrom" — a unit for measuring atoms, not vacuum power — while the product bullet quotes 180AW. The control method is listed as App on a machine with a push button and a mains cable. Buy it if you want a cheap, light, heavily reviewed tank; do not buy it if you want specs you can trust on the page.
Vacmaster Power 30 Wet and Dry Vacuum, 30L
Third for the biggest stainless-steel tank in the corded group — 30 litres — backed by 1,798 ratings at 4.4 stars.
Advantages
- 30-litre stainless-steel tank, the largest in the corded group
- 1500W motor with 230 air watts of quoted suction
- 1490W power take-off socket for remote tool triggering
- Drainage plug empties liquids without lifting the drum
- 1,798 ratings at 4.4 stars
Disadvantages
- 87 dB — the loudest machine in this ranking
- Runtime listed as 30 minutes on a corded machine
- Single power level, no variable suction
- 5% of its ratings are one-star
Third is the bigger Vacmaster. The number that separates it from the Multi 20 above is 30 litres of stainless steel against 20 litres of plastic, at £87.99 versus £66.99. It carries 1,798 ratings at 4.4 stars, so the sample is real, if smaller than the two machines ahead of it.
In practice this is the workshop wet and dry vacuum of the pair. The motor is quoted at 1500W with 230 air watts of suction, the power take-off socket is 1490W, and a drainage plug lets you empty liquids without lifting the drum. The stainless tank is what pushes weight to 5.85kg. Meanwhile the footprint is 39.5 x 39.5 x 63 cm, so it needs a corner rather than a shelf.
Worth noting: the spec sheet lists a runtime of 30 minutes for a machine that runs from the mains, and 87 dB makes it the loudest product in this ranking. There is one power level and no variable suction. Buy it if you empty a lot of wet waste and want to drain rather than lift; skip it if you work in a small room or care about noise.
Tineco Floor One Stretch S6 Cordless Wet Dry Vacuum
Fourth as the most expensive machine here and the flattest: it reclines to 180° and compresses to 13cm to reach under beds.
Advantages
- 180° lay-flat body that compresses to 13cm for under-furniture cleaning
- 70°C self-cleaning flush plus sealed 70°C drying
- 40-minute quoted runtime from a pouch battery
- 70 dB, tied as the quietest machine in this ranking
- Three-chamber dirty water separation protects the motor
Disadvantages
- £349.00 — the highest price here
- 0.85-litre tank needs frequent emptying on large floors
- 9.03kg, the second-heaviest machine in the list
- 11% of its 828 ratings are one-star
- Item dimensions listed as 110 x 26.5 x 23 cm
Fourth is the most expensive machine in the ranking at £349.00, and the one built for a different job. The Floor One Stretch S6 is a cordless wet dry vacuum that lays flat to 180 degrees and compresses to 13cm, so it reaches under beds and low furniture. Its fresh-water tank holds 0.85 litres.
In practice the draw is that flat reach plus the cleaning cycle: 70°C water flushes the pipe and brush roller, then the roller is dried in a sealed 70°C cycle. Suction and water use are adjusted automatically, runtime is quoted at 40 minutes, and noise is 70 dB — level with the iFLOOR 5 as the quietest figure here. A three-chamber dirty water system keeps waste away from the motor.
That said, £349.00 buys 0.85 litres of dirty-water capacity and 9.03kg to push around, the second-heaviest machine in this list. The surface field lists Bare Floor while the recommended uses mention carpets, so treat the carpet claim carefully. Crucially, it has the weakest review profile in the top five: 4.2 stars from 828 ratings, with 11% of those at one star. Buy it if hard floors and under-furniture reach are your problem; skip it if you want one machine for a wet garage floor.
BISSELL CrossWave HF2 Wet & Dry Vacuum, 3845E
Fifth as the cheapest wet and dry vacuum here that mops as it vacuums, with one-press self-cleaning and self-propelled steering.
Advantages
- £179.99, the cheapest machine here that vacuums and washes in one pass
- One-press self-cleaning cycle flushes the brush roll
- Self-propelled steering reduces effort on long floors
- 74.3 dB, quieter than the corded tank machines
- Ships with 236ml of cleaning solution and a hard floor brush roll
Disadvantages
- Title says 340W while the wattage field says 290 watts
- 0.75-litre tank means frequent emptying
- Corded, so not suited to stairs or outdoor use
- 8% of its ratings are one-star
Fifth is the BISSELL CrossWave HF2 at £179.99. It is the cheapest wet and dry vacuum here that mops as it vacuums on sealed hard floors — the Tineco iFLOOR 5 below it undercuts it by 99p, and that one is cordless. BISSELL holds 230 ratings at 4.3 stars and a 0.75-litre dirty-water tank.
In practice it is the simplest machine to run in this ranking. There is one power level, an auto mode, automatic solution dispensing and a self-cleaning cycle that rinses the brush roll and pushes debris into the dirt tank at the press of a button. Steering is self-propelled, noise is quoted at 74.3 dB, and the lead is long enough to cross a home without replugging.
However, the name and the spec table disagree on power. The title says 340W; the wattage field says 290 watts. That is a 50W gap on the headline number. The 0.75-litre tank also means emptying often on a large floor, and the machine is corded, so it is not the tool for stairs. Buy it for sealed hard floors; do not buy it for carpets or a wet workshop floor.
Tineco iFLOOR 5 Breeze Complete Cordless Floor Washer
Sixth at £179.00 — 99p under the BISSELL above it — as a cordless wet dry vacuum mop with a 35-minute runtime.
Advantages
- £179.00, undercutting the BISSELL above it by 99p
- Cordless with a quoted 35-minute runtime
- Dual-tank system keeps clean and dirty water apart
- Hands-free self-cleaning plus centrifugal roller drying
- Edge cleaning quoted down to 0.20 inches
Disadvantages
- Maximum suction listed as "1064 Inches" — a length unit
- Voltage field says 120 volts
- Hard floor, hardwood and laminate only
- Only 87 ratings, the thinnest sample of any cordless machine here
Sixth is the iFLOOR 5 Breeze Complete at £179.00, 99p less than the BISSELL above it and cordless. It vacuums and mops sealed hard floors in one step, keeps clean and dirty water in separate tanks, and its tank is quoted as 30% larger than the iFLOOR 3 series.
In practice the flat scraper is the part that does the work: it clears debris and squeezes dirty water out of the roller on every pass, so the brush you push forward with is a clean one. Self-cleaning is hands-free, edge cleaning is quoted down to 0.20 inches, runtime is 35 minutes and noise is 70 dB — tied with the Floor One Stretch S6 as the quietest here. The catch is the spec sheet: maximum suction is listed as "1064 Inches", and inches measure length, not suction. The voltage field says 120 volts, which is not the mains figure for a machine sold here.
At 87 ratings this is also the thinnest review base of any cordless machine in the ranking. Buy it for a flat with sealed hard floors; skip it if you have carpet, pets, or more than 35 minutes of floor to cover in one go.
Lumberjack 50L Workshop Dust Extractor, 1200W
Seventh as the only machine here built for power tools rather than floors — a 50-litre extractor with HEPA filtration to 0.5 microns.
Advantages
- 50-litre drum, the largest capacity in this ranking
- HEPA filter and filter bag quoted down to 0.5 microns
- Five-piece adaptor kit steps down from 100mm to 35mm
- Quick-release clamp for fast emptying of dust and chippings
- 381 ratings at 4.3 stars
Disadvantages
- No wet pick-up described anywhere in the listing
- 10.4kg and a 71.6 x 43 x 43 cm footprint — it needs a permanent spot
- 82 dB, the second-loudest machine here
- 2 metre hose is short for large workshops
Seventh is the Lumberjack, and it is worth saying plainly that this is not really a wet and dry vacuum at all. It is a 50-litre workshop dust extractor: 1200W, a 2 metre hose, a 100mm outlet and filtration quoted down to 0.5 microns through a filter bag and HEPA filter. It carries 381 ratings at 4.3 stars.
In practice the design points at woodworking machinery, not floor spills. The five-piece adaptor kit steps 100mm down to 105mm, 70mm, 45mm, 40mm and 35mm, so it connects to saws, sanders and routers. A quick-release clamp lets the whole lid come off for emptying sawdust and chippings. As a result it weighs 10.4kg, the heaviest machine in this ranking, on a 71.6 x 43 x 43 cm footprint.
Even so, capacity is the whole point: 50 litres of metal drum for a workshop that generates waste faster than a bucket can hold. Nothing in the listing describes wet pick-up, so do not expect it to lift a spill. At 82 dB it is also the second-loudest machine here, and the 2m hose is short for reaching across a bench. Buy it if you run power tools; skip it if you want one machine for the house and the garage.
Dreame H12 Pro FlexReach Wet and Dry Vacuum
Eighth on quoted suction — 18,000 Pa — but only 26 ratings, with a histogram that splits between five stars and one.
Advantages
- 18,000 Pa quoted suction, the highest figure in this ranking
- 180° lie-flat body reaches gaps from 14cm
- 90°C self-clean followed by five minutes of hot-air drying
- TangleCut scraper cuts hair off the roller during use
- 50-minute quoted runtime
Disadvantages
- Only 26 ratings — the weakest cordless sample here
- 500ml tank is small for a full floor
- No three-star ratings at all; 8% are one-star
- £279.00 for a machine with very little buyer history
Eighth is the dreame H12 Pro Flex Reach at £279.00. The headline number is 18,000 Pa of quoted suction, the highest stated anywhere in this ranking, paired with a 480 RPM brush. It also lays flat to 180 degrees and fits gaps from 14cm, with a used-water tank that keeps dirty water away from the motor.
In practice the numbers that shape daily use are smaller ones. The tank holds 500 millilitres, runtime is quoted at 50 minutes, and the self-clean cycle uses 90°C water before five minutes of 90°C hot-air drying. A TangleCut scraper cuts hair off the roller as you work, which matters in a house with pets or long hair.
Even so, this is the weakest review base of any cordless machine here: 4.3 stars from 26 ratings. By contrast with the machines at the top, buyers land at either end — the histogram shows no three-star scores at all, with 8% at one star and 69% at five. Buy it if flat reach under low furniture is the problem you are solving; wait if you would rather not be an early adopter at £279.00.
Kärcher WD 2 Plus Wet and Dry Vacuum, 15L Stainless
Last because £5.44 over the yellow Kärcher buys three extra litres and 111 times less review history to judge it by.
Advantages
- 15-litre stainless-steel tank for £5.44 more than the 12-litre model
- 74 dB, quieter than the 12-litre Kärcher's 79.2 dB
- Recommended uses cover car interiors, stairs, pet hair and outdoor work
- 5.5kg with a stated indoor and outdoor rating
- Cartridge filter needs no swap between wet and dry work
Disadvantages
- 24 ratings against the 12-litre model's 2,664
- 14% of its ratings are one-star
- Included components are just a floor and crevice nozzle and a cartridge filter
- One product bullet, so there is very little specification to check against
Last in this ranking, and the reason the article exists: the second Kärcher WD 2 Plus. This is the 15-litre stainless-steel version at £66.44 — the black one, model WD 2 Plus S V-15/4/18/C.
In practice, £5.44 more than the yellow 12-litre model buys three extra litres, a stainless-steel tank and a stated outdoor use. Weight is 5.5kg, noise is quoted at 74 dB, and the recommended uses list carpeted floors, car interiors, stairs, pet hair removal and outdoor work. On paper it is the better wet and dry vacuum for pet hair of the two Kärchers. It arrives with a floor and crevice nozzle and a cartridge filter, and that is the whole box.
That said, 24 ratings is not a review base, it is an anecdote. Set against the yellow model's 2,664 ratings, that is 111 times less history to judge by, and its own histogram puts 14% of those ratings at one star. Buy it if you specifically want the 15-litre stainless tank and a wider list of recommended surfaces; otherwise the yellow machine at £61.00 gives you far more buyers telling you what to expect.

| 9 | Kärcher WD 2 Plus Wet and Dry Vacuum, 15L Stainless | £66.44 | 4.3 (24) |
Final Verdict
For most homes, the Vacmaster Multi 20 at £66.99 is the sensible pick: 20 litres, 2,539 ratings and a 1740W power take-off socket, for a few pounds more than the smaller Kärcher. If you want a wet and dry vacuum that lifts dry dust as well as spills, the 15-litre Kärcher at £66.44 has the bigger stainless tank and a stated outdoor use — however, with 24 ratings you are trusting the badge, not the crowd. And if mopping and vacuuming in one pass matters more than tank size, the Tineco Floor One Stretch S6 is the quickest route at £349.00, though it weighs 9.03kg. Either way, compare the numbers on the page against each other before you buy a wet and dry vacuum on name alone.
Why trust this ranking?
We rank on price, customer ratings and the specifications that decide the job, and we read each specification table against the marketing bullets on the same listing. When a number does not survive that check, we say so in the entry rather than quietly dropping the product. We also say when a product is the wrong one for you.
