The words on the fuel tank:
"among engine exhaust emissions there toxic CO so never use in an enclosed room without good ventilation"
doesn't bode well for a start and seems to indicate that the machine is made by the same Chinese factory that makes the majority of petrol washers on Ebay.
A
similar one on alibaba is available with differing sized 'Honda' engines. These are not in fact Honda engines but manufactured by a Chinese company who are the subject of litigation by Honda as we speak. The same machine is branded jet-usa in Australia.
Most of the sellers on ebay (uk and au) have similar negative feedback about this machine which seems to fail after about 6 months.
They only cost £65 in china so get one shipped direct......on the other hand get 2 so you get a whole year of cleaning....lol
