Main Difference Between the Models
Dolphin E70 and Sigma robotic cleaners have all the required features to clean the swimming pool. But there are some small options that provide only one of the models. The main differences are listed in this section.
- Dolphin E70 has a caddy for storage and transportation in the package. For Sigma, you need to buy it separately.
- Only Dolphin Sigma has a gyroscope to ensure better orientation in the pool and prolongs the time for cleaning on the waterline.
- Dolphin E70 has a filter basket, while Dolphin Sigma has twofilter cartridges. This does not impact the functionality, and both filters are extra-large.
- Dolphin Explorer E70 has three cleaning cycles (short, default, and long), and Sigma has only one default cycle.
- E70 is equipped with one standard and active brush; Sigma has two combined brushes.
- E70 has a pick-up mode and fast water release function for easier, cleaner extract. The Sigma model does not provide these options for owners.
- The Explorer E70 model is considerably more expensive than the Sigma model.
