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: Excellent item. - Works well and saves times as it combines a number of functions.

## Questions & Answers

**Q: Can any car shampoo be used with this?**
A: I believe so yes. 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.

### ⭐⭐⭐⭐ Kärcher WB 7 Plus 3-in-1 Corded Electric Wash Brush
*by T***3 on 22 November 2024*

The Kärcher WB 7 Plus 3-in-1 Corded Electric Wash Brush is a decent accessory, especially considering I got it for free with my jet wash. To be honest, I probably wouldn't have purchased it separately, but it does get the job done. It works well for cleaning surfaces like cars, patios, or garden furniture, and the three-in-one feature with different brush heads is convenient for tackling various cleaning tasks. However, while it does perform its job, it doesn’t quite reach the level of greatness. The cleaning power is good but not outstanding, and I found that it sometimes takes a bit more effort or time to get surfaces really clean compared to more specialized brushes. Additionally, the corded design can limit mobility a bit, especially if you’re working on larger areas. Overall, it’s a functional tool and certainly an added bonus when bundled with a jet wash. But if you’re looking for a top-tier electric wash brush, there are likely better options out there. For basic cleaning, though, it’s a solid, no-fuss choice.
