Dramatically expand your cleaning radius and eliminate the hassle of constantly moving your machine with the Karcher 3.5m Extension Suction Hose (2.863-305.0). Designed as a premium upgrade for Karcher's highly popular Wet & Dry vacuum range, this specialized vacuum extension hose seamlessly connects to your existing setup, instantly providing an additional 3.5 metres of flexible reach. Whether you are extracting dust from a crowded workshop or reaching deep into the cabin of a large vehicle, this accessory allows you to leave the heavy vacuum canister safely stationary while you maneuver freely around obstacles.

Engineered for relentless durability, this authentic Karcher vacuum accessory is manufactured from thick, crush-resistant reinforced plastic. It safely handles both heavy, sharp dry debris and massive volumes of wet slurry without kinking, collapsing, or restricting the machine's powerful airflow. Compatible with a vast array of Karcher WD (Wet & Dry) and MV series vacuums, it features a highly secure, friction-fit connection system that guarantees an airtight seal. Upgrade your cleaning efficiency and protect your machine from tip-overs on the stairs with this essential 3.5-metre extension hose.

Who Is This Extension Suction Hose Ideal For?

The Karcher 3.5m Extension Hose provides massive reach and crush-proof durability. It is highly recommended for:

  • Automotive Detailers & Car Enthusiasts: Leaving the bulky vacuum canister outside the garage while threading the hose deep into the car cabin to thoroughly clean under seats and inside boots.
  • DIY Renovators & Tradespeople: Attaching the extended hose directly to power tools (like sanders and saws) to extract sawdust while maintaining complete freedom of movement on the workbench.
  • Homeowners with Stairs: Safely leaving the heavy vacuum unit at the bottom of the staircase while utilizing the 3.5m reach to clean all the way to the top step without risking a dangerous fall.
  • Workshop & Garage Managers: Easily vacuuming large, expansive garage floors and navigating around parked vehicles without constantly having to unplug and move the main machine.

Key Features and Performance Benefits:

  • Massive 3.5-Metre Extension: More than doubles your standard cleaning radius, significantly reducing operator fatigue and speeding up large-scale cleanup jobs.
  • Crush & Kink-Resistant Build: Manufactured from premium, heavy-duty corrugated plastic that easily bounces back if accidentally stepped on during a busy workshop shift.
  • Wet & Dry Capable: 100% waterproof and highly chemically resistant, making it perfectly safe for extracting flood water, wet mud, and sharp dry debris alike.
  • Maintains Peak Suction: The smooth internal diameter prevents air turbulence, ensuring your vacuum maintains maximum suction power even over the extended distance.
  • Airtight Secure Fit: Genuine Karcher engineering ensures the extension cuffs slide perfectly onto your existing hose and wands, completely preventing frustrating air leaks.

How does this extension hose connect to my vacuum?

This is an 'extension' hose. It is designed to connect to the end of your existing Karcher suction hose, bridging the gap between your original hose and your metal/plastic extension wands or floor tools.

Will this fit my Karcher WD3 or WD4?

Yes, this 35mm extension hose is universally compatible with almost the entire range of Karcher WD (Wet & Dry) and older MV series vacuums.

Will adding 3.5 metres of hose make my vacuum lose suction?

There is always a marginal drop in suction when extending any vacuum hose, but because this is a genuine Karcher part with a smooth internal bore, the suction loss is virtually unnoticeable during standard cleaning tasks.

Can I use this to suck up water?

Absolutely. The high-grade reinforced plastic is completely waterproof, making it perfectly safe to use for wet extraction, plumbing spills, and garage mud, provided your vacuum is set up for wet use.

Is the hose crush-proof?

It is highly crush-resistant. The ribbed, corrugated design gives the hose structural memory, meaning if you accidentally step on it in the garage, it will pop back into its round shape without permanently kinking.

What is the diameter of the hose?

The hose utilizes the standard Karcher 35 mm nominal diameter, ensuring it fits perfectly onto standard Karcher floor tools, crevice nozzles, and power tool adapters.

Can I connect two of these extension hoses together?

While it is physically possible to daisy-chain them using the friction cuffs, adding 7+ metres of hose will start to significantly reduce the airflow and suction power of your vacuum motor.

Will this fit a Karcher T10 or T12 commercial tub vacuum?

No. The commercial T-Series tub vacuums use a different 32mm clip-ring system. This 35mm extension hose is specifically engineered for the domestic and light-commercial WD/MV Wet & Dry range.

Is this hose heavy to drag around?

Not at all. Despite its durability, it weighs only 0.8 kg. This lightweight design ensures you can easily hold it up to vacuum high shelves or clean inside tall vehicles without arm fatigue.

Can I use this to attach my vacuum to my circular saw for dust extraction?

Yes! The 3.5m length is highly favored by tradespeople. It allows you to connect the hose to your power tool's dust port and move freely around your workbench without the vacuum getting in your way.

Is this a genuine Karcher accessory?

Yes, this is a 100% genuine Karcher OEM accessory, guaranteeing perfect, airtight fitment and high-quality European manufacturing standards.

Do you offer trade pricing for car detailers?

Yes, Freshway Supplies provides highly competitive volume pricing and trade accounts for professional auto detailers, workshop managers, and commercial cleaners. Contact us to establish your account.
