T-300 Patio Cleaner Attachment

Can be attached to any Kärcher domestic pressure washer that has the bayonet style attachment to the trigger gun. Predominantly a patio-cleaning device that can be used on fencing, garage doors and a number of different surfaces.

It has two dirtblasting nozzles on opposite ends of a propeller attached inside the outer casing. When the high pressure water is blasted through the lance and propeller, a hovercraft effect is created that cleans the whole patio in a tornado effect.

It reduces the cleaning task by five times thus decreasing motor wear, water usage and time spent cleaning. The cleaning nozzles are height adjustable to cater for different floor or wall surfaces. Finally the outer casing protects from splash back, which stops irritating dirt being spread around your home.


  • Two dirtblasting nozzles
  • Hovercraft effect
  • Cleaning splash back protection
  • For wooden decking, patio flooring, tiles and concrete
  • Five times faster than regular spray lances
  • Working diameter of 265mm


This attachment is suitable for all domestic pressure washers in the K2-K7 series.

    Works as per demo video, light and easy to use. A bit fiddly changing between pressure wash lance and this attachment. Did over 100'sq M of block paving and cleaned up well. Pressure lance still required to shift some moss in joints and clear debris lifted out of joints and dirt cleared from surface.
  • A great, time-saving attachment...!

    A really great, time-saving accessory from the Kärcher stable — although, as the power washer we own is only a K3 model I feel we may not have obtained the full benefit from this excellent attachment, that we probably would have got if we had owned a higher-numbered model of washer.
  • It does what it said it does

    I found this patio cleaner is an improvement on the old style which i had a T 50 it cleans better and the covers the area much quicker as it,s nearly twice the size. I did phone before purchasing to make sure i had the correct product and spoke to a young gentleman who was very helpful i would use this firm again.

    The water pressure through the jets is ok but the arm has stopped spinning Can you advise

      It is likely that either the spindle and bearings Stock Number: ES952758 are worn or the spray arm itself.

  • Q I have a Karcher 520M and cannot fit the T racer 300 to the bayonet gun 1 Answer

    The patio cleaner has two silver pipes with it one of which should fit into the bayonet fitting. It doesn't get in with sufficient depth to twist the handle to hold firm. The protecting shroud on the second pipe is what is the problem. Can it be adjusted in some way? I'd appreciate any advice you can give.

      If the locking shroud will not allow fitment to your gun you may have to replace the gun assembly.

      This will fit any Karcher 'trigger unit' provided it has a standard Karcher bayonet fitting.
