Due to the fact that I have only had the machine 3 months, it has not needed to be serviced, and I have yet to have any major problems. I did have one brass coupling that cracked, and it was sent to me first class, and got it the following day.
Therefore, the jury is still out..... However, I have found Matt at Cleansmart to be very good indeed, and I am confident that I will have no problems.
The wonder wand does take some getting used to, but you must stick with at....I am glad that I paid the extra.
