Krcher's eco!Booster is a replacement jet pipe for the K 7 pressure washers. Wider spray than the standard flat jet nozzle, so you cover more area per pass. Krcher reckon 50% more efficient with the same water and energy.

Worth upgrading?

If you've got a K 7 and you're sick of doing six passes over the patio, this sorts it. Wider coverage means the job's done quicker. Clips on and off one-handed with the side buttons, so swapping lances takes a couple of seconds.

Only fits K 7 models. Won't work with anything from the K 2 up to K 5. Sold direct by Krcher on Amazon.
