Kirby is known to be sold after door-to-door cleaning demonstrations, by local dealers and salesmen. Only recently these products appeared in online shopping sites such as Amazon. The Kirby Sentria 2 is not just a vacuum cleaner; it's a cleaning system. It comes with a wide range of features, accessories and attachments. It's the only home appliance that I know which can vacuum your bare floors, shampoo your carpets and even paint your walls. If money is not an issue, the latest Sentria is definitely worth taking the place of your old vac, here is why.
All Kirby products perform very well at this chapter. Users can set the height of the floor contact point by using the pedals located on the front wheels. Several studies showed that the Sentria 2 has the strongest suction power of all Kirbys: about 115 CFM. The machine comes with 2 brushrolls coupled to the motor through a belt, a soft one meant for carpets and rugs, and a stiff one designed for picking up pet hair.
Naturally, the vacuum has different input powers, depending on the usage. For normal nozzle usage, Sentria consumes around 630 Watts (5.9 Amps) at which the the brushroll reaches a speed of 4000 RPM. If you use the hose, the power input raises to 710 Watts.
Filtration system efficiency
Sentria has filtration at different levels. First, the bags presented above filter most mites and small dust particles. Second, the HEPA filter is not allowing airborne particles smaller than 0.3 microns to leave the air fan.
Weight and Dimensions Since it's mostly built of aluminum and polymer (an improvement from older models) is weights around 20 pounds and measures 43 x 15 x 15.
