They will do a good job Richard.
At the 1 day course I went on at Leicester racecourse we had a large area of floor to go thro.
We started at one end basically with a mop and bucket (mop was microfibre), and a wet vacuum. We got a result.
As we went along we then used a rotary with a stiffer brush then for carpet cleaning, and the wet vac. got a result - slightly better.
Then we used the Masterforce from Solutions with a spinner and its own suction. Maybe better result.
Then finally we used Steve knights tm with loads of heat and suction, along with the spinner. Better result.
So we got a result with all 4 methods, but as we went a long the job got easier, maybe a tad quicker, the floor dried quicker etc ...... but at a cost.
Obviously with a large area, which that was, and you get lots of those jobs - the TM was best .... but at a cost.
If you just doing someones kitchen or hall, you can do a good job with the "basics".
Good operator methods is obviously a necessity, as is the cleaning fluid. That day we were using STS from Solutions Cornwall (it was one of their traing days and a bargain at £45+vat).
