The Kärcher TLA 4 telescopic spray wand is not specifically listed as a compatible device for the Kärcher MX 720. The compatibility of the TLA 4 telescopic spray wand is mainly indicated with a variety of Kärcher high pressure cleaners from the K 2, K 3, K 4, K 5 and K 7 series, but the MX 720 is not mentioned in the lists of compatible devices. It is therefore advisable to check directly with Kärcher or an authorised dealer before use to ensure that it is compatible with your model.
