Notes

Kärcher prints its hose size as a nominal width (DN, shown as 'ID 35' / 'ID 40' in the technical-data table) and does not print the hose's real inside or outside diameter, or the bayonet or clip dimensions. The only other figure is the shipping-size line of the bent hose: 2550 x 35 x 35 mm.
Clip 1.0 / bayonet 1.0 fit machines made up to 2016; clip 2.0 / bayonet 2.0 fit machines from 2017 (Kärcher's footnotes). The two generations differ, but the pages give no sizes for either.
Only the numbers each source prints are listed, in the source's own words for what they measure. 'Nominal family' is the maker's own size label; it is not a measurement. Hose 'ID / OD' is the hose body, 'cuff / connection' is the end fitting, 'tool or accessory port' is the other side of an adapter. Inch figures are as printed; the mm in brackets are 25.4 mm per inch. A taper is listed only where a source prints it, and none does. Xem does not make these parts; measure your own hose before you size an adapter.

Questions

What does DN 35 mean on a Kärcher hose?

Kärcher's technical-data table prints 'ID 35' (the description says DN 35): a nominal width. The real ID, OD and connector sizes are not printed.

Is Kärcher bayonet 1.0 the same for DN 35 and DN 40?

Yes: the page says the bayonet 1.0 connection is the same across nominal widths 35, 40 and 50.
