There are only three stone saws that compete with the saws from iQ Powertools. All three of these saws use either water or an external vacuum unit. Despite the fact that they use this technology, they cannot handle more than 1-3 hours of use during an 8-hour working day to stay within the grass values. If you want to avoid water, sludge and external vacuum cleaners, if you want to be able to saw stone 8 hours a day without exceeding the limit values, then iQ Powertools is the obvious choice.
