Is it better to brush or vacuum a pool?

Brushing and vacuuming do different jobs, so neither wins outright — but if your pool has algae buildup or debris on the walls and steps, brushing first is the more important step because vacuuming alone won't dislodge growth from surfaces.

Brushing breaks algae and biofilm loose from gunite, fiberglass, or vinyl surfaces and suspends debris in the water where your filter can capture it. Vacuuming then removes settled debris from the pool floor. Skipping brushing and only running a suction-side cleaner like a Poolvergnuegen — which vacuums the floor on every cycle — means wall algae stays attached and spreads. The correct sequence is brush first, let the pump run, then vacuum.

• Brushing frequency: pool walls and steps should be brushed at least once per week to prevent algae adhesion.
• Suction-side cleaners like the Poolvergnuegen W3PVS20JST and W3PVS40JST vacuum the floor but do not mechanically scrub walls.
• After brushing, allow the pump to circulate for at least 1–2 hours before vacuuming to let debris settle to the floor.
• Vacuuming frequency: pool floors typically need vacuuming 1–2 times per week depending on debris load and bather use.
