Waxit Recommended Pressure Washer Upgrade Kit - Gerni / Stihl · No MTM Cannon$367.95 About Waxit Recommended Pressure Washer Upgrade Kit - Gerni / Stihl
Designed to replace the weak links in your Gerni & Stihl setup - this upgrade kit fixes hose kinks, adds proper control, and makes detailing smoother from start to finish.
This Pressure Washer Upgrade Kit for Gerni & Stihl 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 Bent lance and Tecomec Ceramic 1/4" QC 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.
Want to foam as well? The kit is also available with an MTM foam cannon as an option - just choose "With MTM Cannon" when ordering.
Adaptors are included for both older and newer Gerni and Stihl 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.
This kit will not work with internally plumbed hose reel models.

Short Gun Precision
The MTM SG35 short pressure washer gun offers better control, quick-connect compatibility, and a tight, responsive feel. Built for detailing work, not just general cleaning.
Anti-Kink, Lightweight Hose
The 15.2m UBERFLEX hose is lighter, more durable, and far less prone to snagging or memory. Polyurethane outer shell with full abrasion and UV resistance.
Ceramic 1/4" Nozzle Set
All featuring durable ceramic inserts designed for long-term performance and consistent spray patterns. From heavy grime removal to maintenance washes on coated vehicles.
Foam Cannon Ready
Optional MTM PF22.3 foam cannon available, mounts directly to the SG35 short gun via 1/4” QC.
Includes M21-M22 and OEM hose adaptors to cover both old and new models.
Frequently Asked Questions
Whether you're upgrading from stock Gerni accessories or switching over from Stihl, here’s what you need to know about compatibility and performance.
Will this kit fit both older and newer Gerni or Stihl models?
Yes, we include two adapters in this kit: one for older M21-style threads and one for newer OEM connectors. This means it will suit most Gerni, Stihl, and Nilfisk models sold in Australia over the past decade.
What makes the UBERFLEX hose better than my original hose?
The UBERFLEX hose is lighter, more flexible, and far more resistant to kinking than the stock rubber hoses. It has a textured polyurethane jacket that reduces drag across concrete and is also UV and abrasion-resistant, ideal for home use where hoses are constantly moved across driveways or patios.
What’s the benefit of the nozzle set?
The Tecomec Ceramic 1/4" QC Pressure Washer Nozzle Set allows you to switch between 15°, 25°, 40°. The 15° nozzle delivers stronger cleaning power, the 25° nozzle is the perfect all-rounder, and the 40° nozzle provides a wider, gentler rinse for paintwork and coated vehicles.
Will this kit work with pressure washers that have hose reels?
Not in most cases. This kit is not compatible with pressure washers that use internally plumbed hose reels, as those reels are usually hardwired into the machine and can’t accept external hose connections. For best results, use with models that connect externally via the outlet port.

- BBBoby B.Verified BuyerReviewingWaxit Recommended Pressure Washer Upgrade Kit - Karcher KI recommend this productRated 5 out of 5 stars4 months agoBrilliant kit
I brought this for the karcher k7 premium model.
On the uberflex flex hose, I did cut one m22 connector off and replaced it with a karcher quick connect barb due to space limitations (i knew prior purchasing that i might need to)
The gun and accessories are a pleasure to use but the best of it all is the uberflex hose,
Easy to untangle but just the added 4-5m extra length, makes the world of difference
WCWaxit Car Care4 months agoStoked to hear you are happy with the kit. Makes life with the pressure washer significantly easier.
Thanks for taking the time to leave a review .

Definitely makes a big difference having the short gun and if you lay the hose out in the sun for a couple of days it won't spring back up as much

Got the upgrade minus the mtm foam sprayer.
Really worth the upgrade, felt like i bought a newer more expensive pressure washer. The hose is really good compared to karchers and the stubby gun and lance for the money are really good.
- FMFevzi M.Verified BuyerReviewingWaxit Recommended Pressure Washer Upgrade Kit - Gerni / StihlI recommend this productRated 5 out of 5 stars5 months agoAwesome products and service
Great products the upgrade kit is great quality so much easier to set up and use. The hose length & quality is so much better the original gerni no more kinks and is long enough to reach around vehicle with ease. Will definitely be more products in the near future

- JFJoshua F.Verified BuyerReviewingWaxit Recommended Pressure Washer Upgrade Kit - Karcher KI recommend this productRated 5 out of 5 stars11 months agoWorth every cent
I decided to finally splurge on this kit to upgrade my Karcher K3. It was worth every cent. I've only used the kit once since I got it (thanks to dreary winter weather), but it made washing the car so much easier. I no longer have to fight the original Karcher hose and gun, which annoyed me to no end. It was very easy to put together. Can't wait for the opportunity to use this kit more!
