Robots are not interchangeable, and the wrong one is an expensive disappointment. Four questions settle it, and we would rather ask them than sell you the unit nearest the door.
**What are you picking up?** Fine sand and silt need a different filtration cartridge to leaves and bark. A pool in a planted yard often needs to handle both, and a machine set up for one will disappoint on the other.
**Does it need to climb?** Waterline and wall cleaning matters if your pool grows a tide mark. Floor-only units are cheaper and perfectly adequate for some pools.
**What is the shape and the surface?** Steps, benches, beach entries, and tiled versus pebble interiors all change what tracks properly and what gets stuck.
**Who is lifting it out?** Weight is the single most common reason a robot ends up in the shed. It is a fair thing to care about and we will not talk you out of caring about it.
We stock and service Dolphin, which matters after the sale rather than during it: if something goes wrong the unit comes back to this counter rather than being posted interstate.
