My son very sensitive to dust and i'm quite worried that he will develop ashma. While shopping for a real good quality machine ( typical Singaporean ) , i got 3 representative to do demo in my house so that i can compare. I called Dyson , Rainbow and Kirby. I finally got Kirby because
Dyson - 2000w , ( high electricty comsumption ) , long host vacuum suction not that strong , water technology , ( About 3k )
Rainbow - About 2500w , 3 hidden filter , very low suction power after few years usage ( About $3.8k )
Kirby - Less than 600w , Nasa technology , very strong suction power , air output is purified air Can be use as sweeper , mop Without Using Water and yet can disinfect the floor using heat technology. Carpet shampoo machine too ( of course need water for this carpet shampoo parts )( About $3850 ) I'M VERY IMPRESSED......
Compare , Compare , Compare. That's Singaporean
