Robust by Name, Robust by Nature – The Karcher WD5 P Wet & Dry Vacuum Cleaner Is the Second Vacuum You Actually Need

In cases where a second vacuum cleaner is required for more robust cleaning (que tidying up after some DIY or sweeping up patio debris), a wet and dry vacuum cleaner will give you the versatility you're after since, after all, you should already have one of the best vacuums to use day to day.

I've tested the Karcher WD5 P Wet & Dry Vacuum to see if it can fulfil its mission of providing a 'powerful, convenient cleaning performance'. For one week, every other day, I have challenged it with: removing debris from the patio, blowing leaves out from underneath a table on the patio (using the blower function), lifting cereal and flour from hard flooring, and even removing water from the kids' sandpit.

The WD5 P has a 1100-watt motor to deliver superior air flow, and a 6.6-gallon container capacity for wet or dry debris. It'll remove the debris that you do not want your household vacuum to tackle, and I've found that it's a good appliance to have before pressure washing the patio (for example).

My One Minute Verdict

Easy to set up and simple to use with brilliant results, the Karcher WD5 P wet & dry vacuum cleaner is certainly one of the better wet & dry vacuums that I have used in a long time.

The 1100-watt motor delivers powerful suction to clear fine dust and heavy debris, and the built-in blower will quickly move dirt and debris from hard-to-reach places. It is a top-mounted design, which means that it is suitable for dry and wet debris, indoors and outdoors, but you'll need to swap out the fleece filter bag for any liquid pick-up.

It's one of six wet and dry vacuum cleaners by Karcher, with the WD5 P positioned toward the higher end. For example, it'll dent the wallet by $249, whereas the Karcher WD4 is $199, and the WD3 is $99.99. It is, however, robust. I've also tested the Karcher WD4, and I found that it is overall more powerful (despite having the same 1100-watt motor), more robust, and much easier to move around.

Throughout testing, though, the 26ft/5m power cable came up short. The 11.5ft suction hose is also gangly. And the 84dB noise level causes a stir.

A wet and dry vacuum cleaner that more closely resembles a cordless vacuum, such as the Dreame Z30 Pro Aqua Wet-to-Dry Vacuum, may be the better option if this noise and practicalities are likely to bother you. Alternatively, the Shark Messmaster Portable Wet/Dry Vacuum is compact enough to take outside to the car and leave it there to clear up after any little accidents, like spilled coffee or chip crumbs.

Karcher WD5 P Wet & Dry Vacuum Cleaner: Specifications

Karcher WD5 P Wet & Dry Vacuum Cleaner: Design and Features

The Karcher WD5 P Wet & Dry Vacuum Cleaner is designed to be used on dirt created by home projects outside of the home, which your standard vacuum simply can not handle.

It has a large 6.6-gallon (25L) container, which is suitable for holding wet and dry debris. The top-mounted filter allows for quick and easy removal from the filter box – without coming into contact with dirt. This means that there is no need to remove the filter as you switch between wet and dry cleaning, but you will need to remove the fleece bag to remove any wet stuff.

The top-mount can be released to access the fleece bag by folding down the handle and lifting to remove.

The WD5 P is packed with a 1100-watt motor, which can either clean up or blow away debris. To alternate between the two functions, attach the 11.5 ft. (3.5m) suction hose to either one of the outlets. You do only have the one power setting to use either function, but I found this ample enough for lifting dry or wet debris – and blowing it too.

It has a 26ft power cable and, unless you have a power outlet outside, you may benefit from an extension cord like this 10ft Amazon Basics cord ($6.99, Amazon). And while the 11.5ft suction hose with bent handle provides some extra length during cleaning, it can make it a difficult appliance to store because it doesn't like being wrapped around the container, and it increases the height required in the shed to house it.

At the base of the container are five wheels that help to maneuver the WD5 P. These are installed as part of the setup. You can either wheel it around by the fixed handle or lift it with this handle when taking it to another space to clean.

What Is the Karcher WD5 P Wet & Dry Vacuum Cleaner Like to Use?

The Karcher WD5 P wet and dry vacuum cleaner is a large appliance that'll need to be stored in the utility room or, better yet, in an outbuilding. It measures 25.7(H) x 15(W) x 16.5(L)in and weighs 19.2lbs, and when it's in use, it will get dirty.

It's designed to be used with either the floorhead or crevice tool attached to the suction tubes while removing debris off the floor, or while using the blower function. I found it easy to switch between the two different functions – blower and suction – by removing the suction tubes and tools, and turning the appliance with the one-speed dial.

The WD5 P is noticeably louder than a standard vacuum cleaner and is more in line with a pressure washer. I recorded a noise level reading of 84dB using the decibel meter reader app on my smartphone. This noise level is the same as that of the Karcher WD4, and it's equivalent to that of a passing vehicle.

Test 1: Flour and Sugar

In instances when you'll be wanting to clean up dust and dead skin, I wanted to see if the Karcher WD5 P could handle it by sprinkling half a cup of flour and half a cup of sugar on our tiled floor in the utility room. The flour is also an excellent visual test, as we can spot when it's left on the floor or stuck in any of the vacuum's parts.

With the floorhead attached to the suction hose and powered by the 1100-watt motor, the WD5 P effortlessly cleared a pathway through the flour and sugar in one clear pass. All the debris made it into the fleece bag; no clouds of 'dust' escaped before, during, and after the removal, either.

Test 2: Pantry

For my next test, I spilled cereal and rice on the tiled floor in our utility room. This was to replicate a scenario where the WD5 P could face larger debris, indoors and outdoors, such as small stones, sawdust, and wood chippings.

The floorhead made a clear pathway through the rice with no grains getting stuck or blown off course. However, the cereal got pushed along by the floorhead unless I lifted and dropped the floorhead on it so that it could be vacuumed. No cereal became stuck or lodged in the hose.

Test 3: Water

As a wet and dry vacuum, I wanted to demonstrate how the WD5 P removed liquid. To do this, I used it in the yard and challenged it with the removal of rainwater from my kids' sandpit after a deluge of rain over the past few days. I figured that it would be a big help to remove and contain the rainwater prior to emptying, rather than to flood the patio and make it wet for play.

When removing liquids, you'll need to remove the bag by lifting off the top of the canister. This will prevent the fleece bag from getting weighed down by liquid and avoid frequent replacement in case the fleece starts to degrade.

For the purpose of the test, I also removed the floorhead to get a clear visual, although it is suitable for use on liquids when the bristles are raised by flipping the switch on the floorhead.

All the liquid was quickly removed from the sandpit and deposited in the container. When I turned off the appliance, water ran back down the suction tubes that were being held in by the strong suction. This is something to be aware of, especially if you're removing floodwater or spilt liquids from washing machine leaks or gas can drops.

Test 4: Attachments

The Karcher WD5 P only comes with one attachment other than the floorhead, and that is the crevice tool. This tool is suitable for targeting the suction and blower delivered by the 1100-watt motor air flow. However, over time, I wouldn't expect this attachment to get much use because you can just use the handle to the same effect.

Throughout the week-long tests, I also used the Karcher WD5 P to clear up the patio in the yard. It was littered with sand from the kids' sandpit, leaves from fall, moss from the roof, and rotting vegetation.

I stretched the 5m-long cable and reached as far round as I could before pulling the plug out of the outlet, and my toddler son wanted to take over.

The WD5 P did a great job at removing everything within its path, with all debris contained in the container. However, some debris did become lodged in the floorhead and suction hose, which limited the suction power. I noticed a shift in gears when this occurred, so I switched off the power to dislodge the tissue and twigs.

Karcher WD5 Wet & Dry Vacuum Cleaner: Setup and Maintenance

The Karcher WD5 P wet and dry vacuum cleaner is a large appliance, so it arrives in a large delivery box. This big, branded yellow box doesn't have any handles, which makes it difficult to move into a space to set up, so I recommend having an extra pair of hands to help out.

A combination of cardboard and plastic packaging secures the parts inside the box. Inside the box are all the parts required to start using the WD5 P from the get-go. This includes: an 11.5 ft. (3.5m) suction hose, (2x) 1.8 ft. (0.5m) suction tubes, hand nozzle, crevice nozzle, a switchable wet/dry floor nozzle, automotive-style pleated filter, and a fleece filter bag. If you're buying the WD5 P in the States, you'll also receive a power tool adapter for attaching to an industrial DN 35 suction hose.

It also comes with the addition of a clip-on storage belt for securing the crevice nozzle and floor nozzle, which, although it isn't classed as an 'accessory' per se, it is a part that doesn't come with the Karcher WD4.

Upon opening, you'll find that the suction hose and five castor wheels are located inside the 6.6-gallon container. It also comes with instructions to "help" with setup, but, as with all Karcher instructions, I found these difficult to interpret and follow because there are no words to support the minuscule diagrams.

Fortunately, I could figure out what goes where using no fewer than some essential DIY skills, such as clipping and slotting together, and some thought.

To set it up, I clipped on the storage belt; attached the suction hose to the container; connected the suction tubes to the hose and hand nozzle; installed the fleece filter bag and popped on the five castor wheels. The pleated filter was already in place. This took no longer than five minutes.

All these parts will need some level of maintenance.

The fleece filter bags will need replacing when they get full, or if they get too damp from removing wet debris. How often you replace it will depend on the type of dry debris that you're removing. Replacement bags can be bought from Amazon for $16.19 (pack of 4), which can be attached by simply opening the bag and placing it inside the vacuum.

The filter bags will need to be removed when vacuuming wet debris or liquids. When this type of debris is being removed, the container will need to be wheeled over to a drain for emptying, which is OK in itself, but the container is large, so it's a bit cumbersome to lift or tip. The liquid will also be filthy dirty, and you won't want that being taken into your home.

In use, I found that the switchable wet/dry floor nozzle and suction tubes became lodged with larger debris, which stopped me in my tracks. I removed the blockage by unclipping the floor nozzle or suction tube (depending on the blockage location).

Over time, a cleaning tip that I would recommend is to wipe each part of the WD4 to keep it in a good working order. The top-mounted filter may also begin to perish and become damaged, so you'll need to replace it with a new one ($22.99, Karcher.com).

How Does the Karcher WD5 P Wet & Dry Vacuum Cleaner Compare?

The Karcher WD5 P is one of eight wet and dry vacuum cleaners from the German brand, which is available in the United States and the UK. As with half of the category, it's mains powered, whereas the other four wet and dry vacuum cleaners by the brand are battery-powered.

It's priced at $249.99 and is available to buy directly from Karcher or resellers such as Amazon (where you might find it a little cheaper). It is one of the more expensive wet and dry vacuums from the brand, with the more expensive tagged at $349.99 (Karcher WD6 PS) and the more affordable at $99.99 (Karcher WD3).

I've also reviewed the Karcher WD4 wet and dry vacuum cleaner and, after comparing the two, note that the WD5 P is generally more robust with sturdier onboard storage; one button to remove the top mount (rather than two clips at the side) and a stronger, fold-down handle. While it has the same 1100W motor as the WD4, it has a greater suction power (260 watts) and can pack away more debris into its 6.6-gallon container.

The wet and dry vacuum cleaners with a plug do fall short on what it can reach to clean because of the length of the power cable – it's just 5m in length, which can be restrictive when working on different jobs around the home. Karcher also has battery-powered wet and dry vacuums, like the WD2-18 Cordless Wet and Dry Vacuum, which is powered by an 18V / 2.5 Ah Karcher battery and has the largest container capacity (3.17 gallons) in the battery-powered category.

Alternatively, I appreciate that not everyone would be looking to have a wet and dry vacuum quiet as big as these Karchers (including the battery-powered), so, if you're after a second vacuum of this nature that is perhaps even more portable, then I'd be looking at the Shark Messmaster Portable Wet/Dry Vacuum.

This option retails for around $100, and our reviewer, Camryn Rabideau, found that it’s a powerful and versatile cleaning tool that can be used all around your home. On test, Camryn found that it had no problem sucking up spider webs, debris under car seats, and even spilled milk, and unlike a full-size shop vac, this model is quick and easy to clean. Plus, it’s compact enough to tuck into a closet when it’s not in use, so it’s ideal for anyone who has limited storage space in their home.

A wet and dry vacuum that more closely resembles a cordless vacuum is the Dreame Z30 Pro Aqua Wet-to-Dry Vacuum. As a stick vacuum, it is a lot lighter to use, and it'll do a great job of removing pet hair from hard flooring and carpets. Our reviewer, Victoria Woollaston, found that 'it's an impressive multitasker that delivers on its core promise of being a full-power cordless vacuum and floor washer in one.' The Z30 also has a self-cleaning station. However, it is almost double the price of the Karcher wet and dry vacuums, which isn't a drawback, just something to think about.

How We Test Vacuums

At Homes & Gardens, we have a dedicated and thorough procedure for how we test vacuums so we can get a like-for-like comparison between models, and to make sure we're recreating real-life circumstances.

I tested the Karcher WD5 P Wet & Dry Vacuum Cleaner as and when it was required over a two-week period. It was used on hard flooring (laminate and tiles), liquids and solids, indoors and outdoors. In addition to running all three standardized tests – flour and sugar; rice and cereal – I used it to clean the moss-heavy patio, and to remove water from the kids' sandpit. This included removing leaves, small stones, and moss fallen from the roof. I then recorded how noisy it was using the DecibelX app.

This gave me the complete picture of how this wet dry vacuum would perform in real conditions, rather than a single test session, including the practicalities of cleaning and storage, and its overall condition after the two weeks of testing.

If you're sold on getting the Karcher WD5 P Wet & Dry Vacuum Cleaner, then it would be wise to know about the things that you can clean with a wet-dry vacuum. However, if you only need a vacuum cleaner for removing dry debris, then check out these vacuum cleaners for pet hair, which are equally as good; just a different spec.
