Living with it
- Consumables
- Maytronics says the CC Plus's top-load Ultra-Fine filter basket is designed for quick cleaning that is recommended after every cleaning cycle. maytronics.com
- Without the app or Wi-Fi
- The cleaner starts and runs its full cleaning cycle from the physical ON/OFF switch on the power supply unit; the MyDolphin Plus app adds remote scheduling, starting, and monitoring on top of that. maytronics.com
- Set-up
- Maytronics' manual says pool water must be within pH 7.0-7.8 and no more than 5000 ppm salt (NaCl) before running the cleaner. maytronics.com
- Maintenance
- Maytronics' manual recommends rinsing all brushes with clean water after every cleaning cycle. maytronics.com
- Warranty
- Maytronics backs the Nautilus CC Plus with a 1-year warranty. maytronics.com
- Known issue
- Maytronics' own spec sheet lists 'Waterline Scrubbing: No' for the Nautilus CC Plus, meaning it cleans floor and walls but not the waterline tile line. maytronics.com
- Off-season storage
- Maytronics' manual says to coil the cable and store the unit in a dry, cool area, out of direct sunlight. maytronics.com
- Safety
- Maytronics' manual says not to plug in the power supply until the cleaner is already in the water, and to make sure the outlet is protected by a GFI or earth leakage interrupter. maytronics.com
- Size
