Nope, not good fro the wood and really not good for the finish. Wood LOVES moisture but moisture damages wood, so you should really be cleaning your wood floor with very minor amounts of an oily based cleaner, NOT with anything with water or steam.
On Vinyl and PVC floors and Linoleum steam is OK
First question would be did it ever work ok. If not it could be undersized or a repair is needed. Fuses, circuit breakers? Coils clean and filters clean?
I pick up the large pieces by hand, then sweep everything I can into a dustpan. After that I run the vacuum over the area.
Sycamore is Non-Toxic ,and a Hardwood. Let it dry out 6 months or more,and you should be OK Sycamore burns OK when seasoned for 6 months but is an absolute pig to split. They used to make wooden chisel handles from sycamore. Why? Because it doesn't split when you hit it with a hammer.
OK
