Waxit Recommended Pressure Washer Upgrade Kit - Gerni/Stihl/Bosch

Designed to replace the weak links in your Gerni, Stihl or Bosch setup — this upgrade kit fixes hose kinks, adds proper control, and makes detailing smoother from start to finish.

The Waxit Recommended Upgrade Kit for Gerni, Stihl, and Bosch pressure washers is built to eliminate the factory flaws — tight coils, plastic connectors, and awkward lance handling. It includes everything you need to move to a high-performance setup: a pro-quality short gun, a lighter and more flexible hose, a proper lance, and full nozzle control.

At the centre is the MTM SG35 short gun, made in Italy with stainless internals, a 360° swivel, and 1/4” quick-connect fittings for fast swaps. It’s a huge upgrade over the oversized plastic factory guns — compact, responsive, and easier to manage in tight spaces or detailed work.

Then there’s the hose: the 15.2m ProPulse UBERFLEX. Built from a textured polyurethane outer with a braided internal core, it won’t kink, it’s UV/abrasion-resistant, and it glides easier over driveways and concrete without catching. It’s also around 10% lighter than most OEM hoses, which reduces fatigue during use.

The MTM 500mm lance and Aquatouch swivel nozzle set give you flexible cleaning angles and fast adjustments — letting you switch between tight high-pressure jets and wide rinse patterns in seconds. You’re covered for every task.

Adapters are included for both older and newer Gerni, Stihl, and Bosch models, so the kit is plug-and-play for most units on the market. Just note: this setup is not compatible with internally plumbed hose reels.

    Superb upgrade

    Purchased the upgrade kit after using the standard Karcher gun and hose once. Having a shorter gun for wheels makes life so much easier and the hose upgrade over the standard one is night and day. No more coiling or kinks and so much easier to manage. The kit also came with all the necessary attachments which made the upgrade seamless!! Great job on the kit
