Had a relatively cheap 110bar Karcher for some years until it gave up on me last Autumn. Powerful enough and done the job on patios, drives etc., Only ever used it on wheels or a distant spray on the car or van. Just replaced with a Nilfisk C125, 125bar and have to say it's a superb bit of kit. Overall it seems to be much better made, the lance haveing a smoother trigger action and the fittings clicking nicely together. Mine came with a patio cleaner, detergent dispenser, a drain cleaning hose and 2 nozzles, one with variable spray, the other with a jet that is cleaning stuff from an old quarry tiled area that the old Karcher wouldn't touch. Obviously comparing new with old isn't 100% fair but the Nilfisk gets good reviews on the detailing forums.
