The 2150 needs to be plumbed for wash water and for discharge.
Hoses will work, and it can discharge into a sink.
It uses a lot of power, and (often) require repair.
Many of them have had hard lives, and while they ARE excellent,
it is a lot like buying a Mercedes that has worked as a taxi.
The troublesome part might be the circuit boards. Can you solder very well ?
I don't begin to know how the machine is supported in Europe.
Between use, chemicals will dry and cake on the rollers. After a 2 week rest,
even if you took an hour to clean the machine, you'll need to take the time to clean the rollers again.
It is a wonderful machine, but it is EASIER to maintain if you use it an hour or two a day.
