Buying Guide: Key Purchase Considerations
How to choose the right hot tub vacuum robot depends on spa size, water depth, and cleaning frequency. Cordless models are ideal for smaller hot tubs and above-ground spas, reducing setup time and trip hazards. Look for runtime that covers a full cleaning cycle, or opt for a model with replaceable batteries. Suction power, debris capture size, and brush configurations influence how well the device handles sand, leaves, and fine silt. If you have shallow water or tight corners, prioritize models with low-water heads or flexible cleaning paths.
