Is this area cleaner worth $150?

This is used and for sale at my home depot. They want $150, apparently they have 3 left. what would they be worth new?

I was thinking of getting into some pressure washing.. I guess this would be for decks and driveways?

... Hard to say.... it could be worth $0. The most expensive part on there is the swivel. If it is bad, you may end up paying $200 - $300 for a new one. Is there any waranty?

How wide is it? It looks small, I wouldnt go lower than a 20 surface cleaner.
What do you have for a machine to use. GMP and PSI ?

You can buy them brand new for 300
