PA: 29.3.,190 R OMANTEL IMG-20160329-WAO... 3. The following customer requirements have been identified for a canister type vacuum cleaner What would be the engineering characteristics mention one only to translate these customer requirements into measurable quantities and specify the units? & 1.5-9) Can easily extend to reach large areas - Dipeng - m (ii) can easily suck dust - (iii) Can be used for a long time. (iv) Can be used for cleaning a variety of surfaces - (v) Does not cause noise polution- (vi) Environment friendly -

Answer 1

Canister type Vacuum cleaners don't have any restriction of size, so these are more powerful compared to others. As engine power is more flow rate as well as suction is also better compared to other cleaners available in the market. Suction and high flow rate provides better & faster cleaning for large areas where dirt is more.

Customer requirements:

i) To reach large areas one require large hose. Length of the hose is measured in Meter.

ii) To suck dust easily one vacuum cleaner requires more suction pressure. Suction pressure is measured in MPa

iii) To use it for a longer time it must be kept in mind that it is used at proper prescribed electricity (current & voltage) with proper cooling of the motor.

iv) These type of vacuum cleaners are good for staircase, bare floors, hardwood floors, surfaces under or behind the furnitures etc. but it cannot clean sofa, carpets etc.

v) As better insulation is provided for the vibration due to its equipments those creates less noise (dB) it is more silent compared to Upright cleaners.

vi) Canister consumes low electricity (given by ampere) as well as creates less noise(given by dB). So it is more environment friendly compared to others.
