Another vote for Nilfisk
However, slight irritations. The hose is quite inflexible so it doesn’t wind back up on the real easily. The hose enters the machine at the base of the unit so it actually restricts ability to move the unit around easily
Which leads to, using it one colds winter morning I was moving the unit, the hose dug in to the tarmac which then meant the unit jumped in to the air a bit and landed on one of the wheels in a way that snapped a wheel off. The way the wheel snapped off meant the whole unit needed to be replaced, however Nilfisk did this with no questions
Only other thing is that I have looked for snow foam lances and appear slightly more expensive and difficult to source than karcher etc
The above isn’t a dont buy, it’s a cracking bit of kit, much better put together than others I have had in the past
