## 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.
