I got a TR5 steam cleaner that has 65psi, 240-270 operating
temperature and 1700W. But the steam alternates between wet and dry
every 1 to 3 seconds or so. When it is wet, it's like spraying water
ruther than vapor. Is this normal?

Due to power limitations, nothing that plugs in the wall can possibly
produce much steam. These things are essentially a way to heat and apply
water at a slow rate. Hot cleans better than cold, but it's still just
water.
