Review: Not light, but very versatile and convenient! - When I saw this 3 in 1 brush from Karcher I knew straight away - it's a great addition to my Karcher. But it turned to be amazing for something unexpected - my polycarbonate pergola roof and not so good for washing the car, which initially seemed a great idea. 1. Weight It's not exactly light. Complexity adds weight which is normal but be prepared that it's heavier than your simple karcher brush. If you add liquid in the reservoir and don't use it early - also adds up. If you work for a long time, especially where you need to hold it upright and non-horizontal surfaces, then it starts to feel heavier. 2. Quality and durability Seems to be a very well made product as usually from karcher. I'd say if you don't drop it regularly then I don't see much happening to it. Well maybe the mode switch but it feel solid in general too. 3. Versatility Big time, 3 in 1 is really a game changer for me when I got to wash my pergola by climbing on it. Without this brush in past years I've used buckets, all sort of attachments that required going up and down, clunky, pure pain. With this brush I went up and finished the job in one go! Sprayed some foam, brushed it over well and then sprayed water - all with a simple mode switch! Super happy in this regard. Not so good / TO NOTE: - I though it would be also an amazing versatile brush for washing the car. However the brush bristles are not so soft and would 100 % scratch you car paint/laquer if you used it on it. So you can use the foam and spray function if you want, and brush for the wheels & rims would surely be fine, but not for the car body. - Spray is great, but you can't control it like on the standard attachment for karcher. It is strong but you can control the power of spray just by reducing the distance from the object you clean. In general, for most jobs, except the car body (if you care about scratching it and the looks), for everything else it's a great versatile brush that can speed up the work and cleaning which it is it's main advantage. Can recommend it! Cheers! Review: A versatile brush that makes car and patio cleaning much easier - This wash brush has been a really useful addition to my Kärcher setup. The three functions make a noticeable difference depending on what you are cleaning. The foam jet gives good coverage and helps lift dirt before you start scrubbing. The high‑pressure flat spray is strong enough to shift stubborn grime without needing to swap back to the main lance. The soft brush is gentle but still effective, especially on car paintwork and windows. The brush feels solid in the hand and connects securely to the pressure washer without leaking. It also saves time because you can switch between the functions quickly instead of stopping to change attachments. I used it on the car, garden furniture and the patio doors and it handled each job well. A handy, well‑designed accessory that makes everyday cleaning quicker and more controlled. Good value for money and perfect for my karcher washer. ## Features - 3-in-1 wash brush: The Kärcher WB 7 Plus combines 3 functions in one product.

It’s just a receptacle that draws fluid through by Venturi effect. I’m sure kärxher would like you to use their product but I just used diluted car shampoo and it worked well. **Q: Would it fit the Nilfisk?** A: No, different connections styles you may be able to buy an adaptor to convert but unable to confirm this. **Q: Which would be best for a big SUV K4 or K5?** A: It depends if you plan on hiding out of the way when your friends drive past. If not, get a K7 like a real man. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Not light, but very versatile and convenient! *by A***. on 25 April 2026* When I saw this 3 in 1 brush from Karcher I knew straight away - it's a great addition to my Karcher.

I use it for car cleaning and it saves me having to constantly change attachmentss when I simply want to give my car a quick wash. Standard fittings mean no leaks, foam generation is not as good as a stand alone bottle, but good enough, durable and versatile. The brush and spray are good enough for us. It is what it is, a Karcher product and it works. ## Frequently Bought Together - Kärcher WB 7 Plus 3-in-1 Corded Electric Wash Brush, 3 Functions: Foam Jet, High-Pressure Flat Spray Nozzle, Soft Brush, Original Accessory for Kärcher Pressure Washer K 2-K 7 - Kärcher 62957500 1 L, 3-in-1 Car Shampoo Plug and Clean, Pressure Washer Detergent - Kärcher 5 L Canister Pressure Washer Detergent, Car Shampoo --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ae/products/533321641-wb-7-plus-3-in-1-wash-brush-3-functions](https://www.desertcart.ae/products/533321641-wb-7-plus-3-in-1-wash-brush-3-functions) --- *Product available on Desertcart United Arab Emirates* *Store origin: AE* *Last updated: 2026-09-09*
