Kärcher Kärcher WD 4V S-20/5/22 Afvalemmer van roestvrij staal, krachtige stofzuiger met 220 AW, 1000 W, met zak, geel/zwart Review

Whether you are a weekend DIY enthusiast, a gardener who regularly tracks soil and leaves indoors, or simply someone who wants a single vacuum that can handle every mess life throws at it, a wet and dry vacuum cleaner is one of the most practical investments you can make for your home. Ordinary household vacuums are designed for light dust and crumbs — they choke on sawdust, short out on spilt water, and clog up the moment they encounter anything larger than a grain of rice. A purpose-built wet and dry vacuum flips that script entirely. It takes on workshop debris, muddy footprints, overflowing sinks, and car interiors with equal confidence, switching between wet and dry pick-up without any fuss. The best models also include clever extras like a blower function for clearing leaves from gravel or inflating paddling pools. If you have ever found yourself reaching for a bucket and mop after a spill because your vacuum could not cope, it is time to consider a machine that can.

Choosing a wet and dry vacuum means thinking about where and how often you will use it. Tank size is a key factor — a 20-litre capacity is ample for most home and garage tasks without being so bulky that storage becomes a problem. Motor power, measured in watts, directly affects suction performance: the sweet spot for domestic and light commercial use tends to be around 1,000 watts. The filter system is equally important, as cheap filters that clog quickly turn a powerful vacuum into a frustrating chore. Look for flat pleated filters with easy-removal mechanisms and built-in cleaning functions. Other features worth paying attention to include blower capability, wheel count and quality for manoeuvrability, and whether the hose, cable, and accessories can be stored directly on the machine. Kärcher has built its reputation on these practical details, and their WD 4 series sits in a compelling mid-range position that balances performance with affordability.

This review examines the Kärcher WD 4 S V-20/5/22, a 1,000-watt wet and dry vacuum with a 20-litre stainless steel tank, a patented flat pleated filter system, and an integrated blower function. We cover its core performance, the filter technology that sets it apart, how it handles in everyday use, the full list of included accessories, and whether it represents good value compared to both cheaper and more expensive alternatives in the Kärcher range.

Powered by a 1,000-watt motor producing up to 220 air watts of suction, the Kärcher WD 4 S delivers strong pick-up performance for wet spills and dry debris alike. The 20-litre stainless steel collection tank strikes an excellent balance: it is large enough to vacuum a full workshop floor or extract a significant amount of water without stopping to empty, yet compact enough at 38.4 × 36.5 × 52.4 centimetres to slot into a cupboard or garage corner. The flat pleated filter sits inside a patented removable cassette, which means you can take it out and replace it without ever touching the dirt — a genuinely useful feature when you have been vacuuming something unpleasant. The built-in filter cleaning technology restores suction with a simple press of a button whenever you notice performance dropping.

Design-wise, Kärcher has equipped this model with several features normally found on pricier machines. The four stable wheels make a noticeable difference to manoeuvrability compared to two-wheel designs — the vacuum glides smoothly behind you rather than needing to be lifted and repositioned. The 2.2-metre suction hose and 5-metre power cable together give you roughly 7 metres of working radius from a single socket, which is enough to cover most rooms without unplugging. A carry handle on top of the unit makes it easy to lift the 8.67-kilogram machine in and out of storage or up a flight of stairs.

In day-to-day use, the WD 4 S proves itself to be refreshingly straightforward. There is a single power setting — no complicated dials or digital controls to fuss over — so you simply plug in, switch on, and start cleaning. The floor nozzle handles hard floors, tiles, carpets, and tapestries without needing to swap attachments, and the included crevice nozzle reaches into tight gaps between workbenches and car seats. After use, the stainless steel tank empties easily, and the cable, hose, tubes, and nozzles all clip onto the body of the machine for compact storage. The blower function is a welcome bonus: connect the hose to the exhaust port and you have a powerful air stream for clearing leaves from gravel paths or drying out damp surfaces.

Out of the box, you get a well-considered set of accessories: the flat pleated filter already installed in its cassette, a cotton filter bag for fine dust collection, the 2.2-metre suction hose, two extension tubes, a floor nozzle, and a crevice nozzle for narrow gaps. The cotton filter bag is worth using when tackling fine particles like plaster dust or ash, as it protects the main filter and extends its lifespan. The patented filter cassette system deserves particular praise — pulling the cassette out, dropping in a replacement, and clicking it back takes seconds and your hands stay clean throughout.

Measuring 38.4 × 36.5 × 52.4 centimetres and weighing 8.67 kilograms, this is a mid-size wet and dry vacuum that does not dominate your storage space. The noise level is rated at 69 decibels, which is typical for the category — noticeable but not painfully loud. Customer feedback reflects solid satisfaction: it holds a rating of 4.4 out of 5 stars from 186 reviews on Amazon, and ranks number 17 in the Wet-Dry Shop Vacuums category and number 4,098 in the broader DIY & Tools category. The vacuum is corded electric, manufactured to Kärcher's standards, and suitable for indoor use on all common floor types.

This wet and dry vacuum is ideal for homeowners, gardeners, and DIYers who want a compact but capable 20-litre machine with a blower function, four-wheel manoeuvrability, and a clean filter-change system — all at a mid-range price.
