Sometimes, you need more than just a vacuum cleaner when cleaning. I’m thinking of the times when cereal has been spilt; the car is in need of a deep clean and the outbuildings need a vacuum. Fortunately, the Karcher WD4 Wet & Dry Vacuum Cleaner<\/a> is designed to handle these messes, and more.<\/p>\n

It’ll effortlessly remove wet and dry debris, and all the things that you’re best vacuum <\/strong><\/a>can’t or won’t want to get involved with. I know this first hand because I’ve been using it over a long weekend in my own home in other scenarios including to vacuum-away spilt dried cereals; clean-up the porch and suck-up water from the kids’ sandpit after a deluge of rainfall.<\/p>\n

On paper, the specification says that the 1100W of suction power will clear fine dust and heavy debris. Was it any good? Keep reading to find out what I think about it, and how it compares with similar wet and dry vacuums. <\/p>\n

My One Minute Verdict<\/span><\/h2>\n

The Karcher WD4 wet and dry vacuum cleaner has been designed for substantial home projects<\/a> where a standard vacuum cleaner lacks the durability required.<\/p>\n

It provides 1100W of suction power to clear fine dust and heavy debris, including the removal of all the things that you really don’t want your household vacuum to get involved with. The top-mounted design means that it is suitable for dry and wet debris, indoors and outdoors; you’ll need to swap out the fleece filter bag for liquid pick-up, though, admittedly, I did find it to be a bit of a faff.<\/p>\n

It’s one of six wet dry vacuum cleaners in the product category, with the WD4 positioned as a mid-range appliance. For example, it has a greater capacity than the WD3 (17L), yet smaller capacity than the WD5 (25L). The price of Karcher wet dry vacuum cleaners ranges from $89.99 to $349.99, and the WD4 is marked up as bang in the middle of this range with a price of $199.99.<\/p>\n

On test, I found it bulky to maneuver around; it has a restrictive 26.2ft power cable and 7.2ft suction hose that I felt like I was wrestling with. If you’re after a wet dry vacuum that is perhaps more portable then I’d be looking at the Shark Messmaster Portable Wet\/Dry Vacuum. <\/a>Alternatively, the Dreame Z30 Pro Aqua Wet-to-Dry Vacuum<\/a> more closely resembles a cordless vacuum, so it’s more portable and versatile, and it handles pet hair on both carpet and hard floors.<\/p>\n

Karcher WD4 Wet & Dry Vacuum Cleaner: Design and Features<\/span><\/h2>\n

The Karcher WD4 Wet & Dry Vacuum Cleaner is designed to be used on the inside of the car, garage floor,<\/a> or on yard jobs that your standard vacuum cleaner can not handle. I see it as the larger cousin to a canister vacuum.<\/p>\n

It has a large 5.3-gallon (20L) container that’ll hold large debris and liquids. The tear-resistant fleece bag slots inside the container and clips over the hose. When you’re vacuuming liquids, it’s advised to remove this bag, although it can easily cope with damp debris such as soggy cereal and wet houseplant soil.<\/p>\n

To access the bag, the motor can be removed and lifted off the container by releasing the two clips on the side.<\/p>\n

You’ll find that the filter is top-mounted too. This is enclosed in the filter box, which can be easily removed without coming into contact with any dirt. This means that in the event that the filter becomes damaged, it can be easily replaced with a new one ($22.99, Karcher.com).<\/a><\/p>\n

The WD4 is kitted out with 1100W of suction power, and the 2025 model (that I have) has a blower function too. There is only one power setting when using the “suction” or “blowing” function, which is strong enough to remove small stones or empty a 200lb <\/strong>sandpit full of water, and blow away dropped damp compost.<\/p>\n

I found that the 26.25ft power cable was sufficient for the cleaning tasks I set. However, I will need an extension cord like this 10ft Amazon Basics cord ($6.99, Amazon)<\/a> so that I can clean the car and further around the patio area. <\/p>\n

The WD4 also has 7.2ft suction hose that connects to two suction tubes to add a further 3.28ft to the overall length when vacuuming; the floorhead or crevice tool accessory (included) simply slots onto the end of a tube. These can then all be taken apart just as easily as they connected together for storing<\/a> onboard. <\/p>\n

It can all be maneuvered as one appliance unit on four castor wheels that slot onto the base of the container as part of the setup. You can either wheel it around by the handle or lift it with this handle when taking it to another space to clean. <\/p>\n

What Is the Karcher WD4 Wet & Dry Vacuum Cleaner Like to Use?<\/span><\/h2>\n

To look at, the Karcher WD4 wet dry vacuum cleaner is big. Measuring <\/strong>20.7(H) x 14.4(W) x 15.1(L)in and weighing 15.2lbs, it is positively a unit and one that I needed to allow a generous amount of space for while cleaning my allocated spaces. It’s also one that I would use and store at ground level because its size would be difficult to carry up\/down stairs.<\/p>\n

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 with the bent handle attached to the suction hose while using the blower function. I found it easy to switch between the two different functions \u2013 blower and suction \u2013 by removing the suction tubes and tools, and turning the appliance with the one-speed dial.<\/p>\n

The WD4 is noticeably louder than a 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 is equivalent to that of a passing vehicle. <\/p>\n

Test 1: Flour and Sugar<\/span><\/h2>\n

In an instance where you’ll be wanting to use the Karcher WD4 to clean up flour and sugar, I spilled some on our tiled utility room floor. I used half a cup of flour and sugar (about 50\/50 split) to see how well the suction coped with fine debris. <\/p>\n

The 1100W suction meant that the floorhead was firmly attached to the floor, but because this debris was so fine, the suction created a clear radius around it, and it removed all the flour and sugar within its path in one clear pass. <\/p>\n

Test 2: Pantry<\/span><\/h2>\n

Next up, I spilt cereal and rice on the floor to emulate the type of larger debris that the WD4 could face, indoors and outdoors. I poured half a cup of cereal and half a cup of rice onto the tiled flooring in our utility room.<\/p>\n

The floorhead effortlessly removed the rice with no grains getting stuck or blown off course from the floorhead. The cereal, however, got pushed along with 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. <\/p>\n
