iShopping.pk brings you the best price for Dyson DC25 Ball All-Floors Upright Vacuum Cleaner With Free Shipping all over Pakistan.
Dyson DC25 Multi-Floor Upright Vacuum Cleaner:
DC25 Multi floor is a lightweight Dyson Ball vacuum cleaner that uses patented Root Cyclone technology for no loss of suction. It has been engineered for powerful cleaning of every floor surface, with a motorized brush bar that can be turned off for hard floors and delicate rugs. DC25 Multi floor also includes patented Ball technology, which allows you to steer with ease around obstacles such as furniture and household appliances. It rides on a ball, so there's no more pushing back and forth to turn corners. At just 16.12 lbs, DC25 Multi floor is one of Dyson's lightest full-size uprights.
Patented Dyson Technology:
Dyson engineers are constantly testing and inventing, trying to find new ways to make their technology work better. As they work, they file patent applications to protect their inventions from copycat manufacturers. That's why the only place you'll find Dyson technology is inside a Dyson machine.
Root Cyclone Technology, for no loss of suction
Ordinary vacuum cleaners rely on bags and filters to trap dust and dirt. Air is meant to flow through tiny holes, leaving dust and dirt behind. The problem is that these tiny holes quickly clog up with particles of dust. This chokes the flow of air, so the vacuum cleaner loses suction. Dyson vacuum cleaners don't rely on bags to trap dust and dirt. They use patented Root Cyclone technology, which spins the air at incredibly high speeds. The cyclones inside a Dyson vacuum cleaner generate centrifugal forces many thousands of times the force of gravity. Dust, dirt and pet hair are flung out of the airflow and straight into the clear bin. No bags, no loss of suction.
The motor of the DC25 is located inside the ball for a lower center of gravity:
Have you ever gotten frustrated pushing an ordinary upright vacuum cleaner back and forth, back and forth to steer around furniture and other obstacles? Have a look underneath it, and you'll see that's because it sits on fixed wheels – perfect if all you want to do is travel in a straight line, but not so good at corners. Frustration is an important source of invention for Dyson engineers – it sparks new ideas, new ways of solving problems. It was their frustration with fixed wheels that led them to develop a new way of turning corners.
Dyson Ball upright vacuum cleaners use patented Ball technology to overcome the steering limitations of fixed wheels. They ride on a ball, which pivots around itself, so you can steer with ease, changing direction with just a turn of the wrist. The idea for Ball technology came about from a Dyson engineer studying new ways to steer. It started crudely - an old wand handle attached to a wheel. Eventually the wheel became a ball- an ideal home for the motor.
The ball itself is made of glass-reinforced polypropylene – the same material used in the manufacture of car dashboards. It combines high impact strength with resistance to distortion. The ball is also where you'll find the motor. By putting the motor inside the ball, at a neutral point, Dyson engineers were able to lower the machine's center of gravity and improve maneuverability even more.
