We used a Spot Pro today to clean 59 dining chairs.
We had to get into a 300 year old cellar under a curry resteraunt to do the job. Tiny twisting staircase just wide enough to get a chair down, no chance of getting a porti down there and couldn't leave it above because of noise and danger of hoses. Very low ceilings and no nearby parking, just a loading bay!!
Job completed, stain free chairs, satisfied customers and
very pleased we had a Spot Pro
