I'm getting ready for some spring cleaning, and my old Vax jet washer has finally given up after last year. I found a deal at B&Q on Karcher pressure washers and I'm torn between the 'K4 Power Control Flex' for £177 with just two lances or spending a bit more for either the K5 Classic at £220 or splurging on the full kit complete with a patio cleaner head, brush, and detergent for £245. Where's the sweet spot when it comes to these pressure washers? Are they a better investment compared to a Bosch model? Any advice would be appreciated!

From my experience, the T5 T-Racer patio cleaner head is a game changer. It cleans faster and more effectively than just using the lance alone!
If you're limited on space, you might consider renting one. I do that and it's great – no worries about maintenance or storage, plus they seem to last forever!
I used to have a Bosch and honestly, I didn’t like it at all. Switched to Karcher and it’s been a breeze. I'm really happy with my choice.
Definitely go for Karcher, especially if you’re interested in the rotary brush. It makes cleaning so much easier, produces less mess, and is gentle on your decking.
This isn’t a direct answer, but I just saw that Screwfix has 15% off Karcher products right now. Just thought I'd let you know while I was there picking up some shelves!

Thanks for the tip! The £245 package includes the T5, a snow foam gun, a brush, and two detergents along with the K4. I think that's the one I'll go for.
