For an innovative, professional-grade pool electric vaccum, you'd ideally look for features that can handle heavy-duty cleaning with high efficiency, particularly for inground and larger pools. Here are some key features and options:

1. High-Powered Suction

• A robust motor with strong suction power to effectively remove dirt, debris, and algae from the pool bottom, walls, and hard-to-reach corners.
• Look for options with multiple suction settings to customize the cleaning for different debris sizes.

2. Advanced Filtration System

• Multi-stage filtration with fine and ultra-fine filter options to capture everything from large leaves to fine sand and silt.
• A large-capacity filter chamber or cartridge system to reduce the need for frequent cleaning interruptions.

3. Cordless or Long Cord Options

• Cordless pool electric vaccums are more portable and eliminate tangling issues. However, if you prefer corded, look for extra-long, swivel cords to cover larger areas with minimal hassle.

4. Programmable Cleaning Cycles

• Some pool electric vaccums have smart cleaning technology that allows for programming cleaning schedules. This is especially helpful for commercial or high-maintenance pools.

5. Battery Life and Quick Charging

• For cordless models, long battery life (up to 2-3 hours) with rapid charging options will allow for prolonged use and faster turnarounds between cleanings.

6. Lightweight and Ergonomic Design

• A lightweight design helps reduce fatigue during use, and ergonomic handles make it easier to move around. Some models even come with telescopic handles for extended reach.

7. Energy-Efficient Operation

• Look for models labeled as energy-efficient to help reduce operational costs, especially for frequent cleaning.
