Hitachi Appliances Inc announced a cordless cyclone vacuum cleaner whose suction power is about 10 times stronger than its predecessor Jan 29, 2015.
Hitachi Appliances realized the strong suction power of the cleaner, "Power Boost Cyclone PV-BC500," by using a newly developed brushless motor, etc. The company plans to release it Feb 21, 2015, with no manufacturer"s suggested retail price.
The expected retail price of the cleaner is ¥80,000 (approx US$678).
The new vacuum cleaner can be used both as a "stick type" and "handy type." For example, it can be used as a stick type by extending the extension pipe of the handle for floor cleaning and as a handy type by rotating the handle to clean a desktop, chair, car interior, etc.
"The center of gravity is near the floor in the stick mode and near the hand in the handy mode so that less load is applied to the hand," Hitachi Appliances said.
It takes about 3.5 hours to fully charge the 2,500mAh lithium-ion (Li-ion) rechargeable battery of the cleaner. The cleaner can be continuously used for about 30 minutes in the normal mode and about eight minutes in the high-power mode.
In a demonstration, Hitachi Appliances used the cleaner to lift up a 6-pound (about 3kg) bowling ball to show its suction power. While the predecessor uses an alternating-current brushless motor, the new cleaner is equipped with a high-revolution direct-current brushless motor.
The company realized the small, light-weight motor by using glass fiber-based composite resin for its casing and blade. Also, it improved motor efficiency by about 20% by optimizing its revolution speed at 85,000rpm.
