Product Features
What makes D7 different from traditional wet dry vacuums?
D7 uses a real-time clean water circulation system that continuously refreshes the roller during cleaning.
This helps maintain a cleaner roller throughout the cleaning process while reducing odors and maintenance.
Does D7 use ozone, UV, or sterilization technology?
No.
D7 does not use ozone, UV light, or chemical sterilization systems.
Instead, it uses continuous fresh-water cleaning technology.
Can D7 clean under beds and furniture?
Yes.
D7 features a 180° flat-reach design and a low-profile cleaning head, allowing it to reach under most furniture.
How long does the battery last?
Under Standard Mode, D7 provides approximately 40–60 minutes of runtime.
Actual performance may vary depending on floor type and cleaning conditions.

Please check:

Please verify:

Why does the battery lose charge when not in use?

This is normal and does not affect cleaning performance.

If the issue remains, contact support.

Cleaning or replacing worn components usually resolves the issue.
