Features

Self-Standing Function

This vacuum does not have a self-standing function. This means it cannot stand upright on its own and needs to be leaned against a wall or laid on the floor when not in use, which can be less convenient for quick pauses during cleaning.

Brushroll Cleaning Function

This vacuum does not have an automatic brushroll cleaning function. Users will need to manually remove hair and debris tangled around the brushroll, which can be time-consuming and require extra maintenance.

LED Headlight Function

The green LED laser illumination reveals invisible dust and debris, making it easier to see and clean dark areas such as under furniture and in corners. This ensures a more thorough cleaning experience, especially in dimly lit spaces.

Convertible Handheld Function

This vacuum can be easily converted into a handheld unit, making it versatile for cleaning furniture, car interiors, and other hard-to-reach areas. This adds to its overall utility, allowing for various cleaning tasks beyond just floors.

Multiple Power Mode Function

The three suction modes (Eco/Mid/Max) offer flexibility to adjust suction power for different cleaning needs. Higher power is available for stubborn dirt, while lower power extends runtime for delicate surfaces, ensuring efficient cleaning for various situations.

Easy Empty Dustbin Function

The one-pull dust cup emptying system allows for quick and hygienic disposal of collected debris without needing to touch the dirt. This simplifies maintenance and reduces contact with allergens, making the cleaning process more convenient.

Overall Rating

The Powerffy Knight 10-US offers strong suction and a good runtime for its price range. It's suitable for everyday cleaning tasks but may lack the advanced features and durability of higher-end models. The aromatherapy feature is a unique addition. Expect a lifespan of 2-3 years with regular use.
