Where can I find parts for this Tornado Pressure Washer P/N 36010?

Either the manufacturers web site or maybe google.

For many full size pressure washers the hose, lance, nozzles and various accessories are almost universal parts that can be supplied by many local businesses that specialise in servicing the local market; professional and serious users that need repairs, replacements and accessories. Such businesses are found in almost every town, often selling and servicing professional vacuum cleaners, janitorial equipment, dust and fume extraction...

Such businesses are a mine of advice and information and a source of hard to find spares...

The compact pressure washer tends to use a lance that is exclusive to the make and model and universal parts do not fit. Replacements might be available in the aftermarket but might only be available as an official spare part.

I'd love to help but need the model #.
look on the base frame for the model # sticker.
