Yes they are just 2% below John Lewis & partners ...
If you want a washer that operates at 110 you need to look at a model with a max bar significantly higher.
I'm not going with karcher again, have a k5 that leaks heavily despite doing everything you should after using, should have realised how easily they break when they have their own dedicated website selling repaired ones, those are just the ones that were still in warranty or those who didn't lose their receipt unlike saps like me.
110bar decent for price.
The reviews for the company don't look great https://uk.trustpilot.com/review/www.karcheroutlet.co.uk
