Did not do a good job for us. Used chlorine in our salt system, never vacuumed. I would not recommend.
UPDATE: our new pool service found a gas leak in the pool heater that postorino has serviced. The chemicals were through the roof!! Do not use this company.
NEW UPDATE: the chlorine in our saltwater pool was SO HIGH, That we had to drain 50% of the water and basically start over. Now that the chemicals have been corrected, my wife can swim without getting scabs all over her back from high chemicals
