When we mapped pool-cleaning prices in Spain, the useful insight was not the lowest number. It was the unit behind every number. Public offers describe hourly labor from €65 including tax, monthly maintenance at €120–€180, or a full cleaning with regrouting at €950. Those figures are not competitors: they represent different commitments.
For 99manos, this reinforces a marketplace rule: normalize scope before ranking quotes. Customers should compare the same pool volume, current water condition, surface material, travel distance, tax treatment, included chemicals, and number of visits. Small pools can also carry a higher effective rate because travel and minimum intervention time are fixed. Better inputs make provider proposals easier to understand and reduce misleading “average price” comparisons.
