The Waxit Recommended Pressure Washer Upgrade Kit gives you better flow, tighter control, and pro-quality components that actually feel good to use.

This pressure washer upgrade kit was built specifically for Karcher’s K Series electric models - the ones that get used on driveways, daily drivers, and weekend jobs. And while the pressure washers are capable, the stock accessories often aren’t. Long lances, heavy hoses, and fixed connections all make the job harder than it should be.

That’s where this kit changes the game.

It starts with the MTM SG35 short gun - a professional-grade, Italian-built unit with stainless steel internals, quick-connect outputs, and a 360° swivel on the inlet. Unlike the OEM Karcher guns, which can feel oversized and restrictive, the SG35 gives you tight, comfortable control at every angle.

Then comes the 15.2m Propulse UBERFLEX hose. This is a textured polyurethane hose designed to glide across driveways, resist UV and abrasion, and not kink every time you move around the car. It’s lighter than the stock rubber hose by about 10%, and it feels way more agile during use.

Also included is the MTM 500mm bent lance, for when you need that extra reach without going full wand mode - perfect for roof lines or lower panels. The Aquatouch nozzle set offers five spray angles including a fan head with a swivel - so you can cut, rinse, or blast without switching setups.
