Buying Guide: What to Look For in a Robotic Pool Cleaner
Cleaning Coverage and Navigation
Your pool cleaner should cover every inch of your pool, including floors, walls, and waterline. Look for models with smart navigation and multiple cleaning modes. The Dolphin Nautilus CC Plus and Aiper Scuba S1 both excel in this area, using advanced algorithms to avoid missed spots. For a deeper look at navigation technology, see our guide on top robotic pool cleaners for inground pools.
Filtration System
Effective filtration is crucial for removing debris from fine dust to large leaves. Dual-layer filtration systems, like those in the Aiper Scuba S1, capture particles as small as 3 microns. Top-load filter baskets, as seen in Dolphin models, make cleaning the filter a breeze. Consider your pool’s typical debris when choosing between standard and ultra-fine filters.
Runtime and Cleaning Modes
Longer runtime means fewer cleaning cycles. The Aiper Scuba S1 offers up to 270 minutes in eco mode, while Dolphin cleaners typically run for about 2 hours. Also, look for flexible modes like floor-only, wall-only, or scheduled cleaning. If you have a large pool, a longer runtime can make a significant difference. For more on runtime comparisons, see our top picks under $500.
Build Quality and Warranty
A robotic pool cleaner is an investment, so durability matters. Dolphin has a legacy of over 40 years, while Aiper offers a 2-year warranty. Look for robust construction, reliable motors, and easy maintenance features. For more on build quality, check our review of wall climbing brushes and pool robot traction brushes.
