3. If your vacuum cleaner is not sucking up the dirt effectively then it could be due to a
clogged filter or hose or a moist bag. Cleaning the filter and the hose can increase the
cleaning efficiency of the cleaner. If required replace the filter that will enhance the
efficiency of the vacuum cleaner.
4. If there is no power supply to the vacuum cleaner then check for any discontinuity along
the wire. Replace the breakers if required and mend and discontinuity along the line.
Another reason for no supply of power could be due to a burned out motor. In this case
we will have to replace the motor.
5. Check the vacuum hose for any holes. A vacuum hose with a hole will face suction
problem. So if there is any hole on the hose than repair it by parting a tape on it.
WASHING MACHINE
12.10 Function of Washing Machine:
Washing machine is the electronic home appliance used to wash the various types of
clothes without applying any physical efforts. With washing machine we don’t have to rub the
clothes with hand or squeeze them to remove the water from them. The washing machine does
wash our clothes automatically without having to supervise its operation. All we have to do is put
the clothes in the machine and select the wash mode. The washing machine automatically
takes the required amount of water and detergent required. It also automatically sets the timer
for washing, rinsing and drying as per the selected mode of operation.

1) Semi-Automatic 2) Fully Automatic
Semi-automatic washing machine: This has separate tubs or vessels for the washer and the
drier. There are two separate timers that enable setting washing and drying times. The washing
tub operates at lower speed whereas the spin drier tub operates at a higher speed. To wash the
clothes, we have to put the clothes in the wash vessel, put sufficient quantity of the water and
detergent and then set the timer. After the specified time, the washing machine will stop. We
can remove the clothes and dry them in the sun or dry them partially in the drier vessel by setting
suitable time.
Fully automatic washing machine: In fully automatic washing machine there is only one tub
that serves as the washer, rinser as well as the drier. Depending on the number of clothes or the
weight of the clothes, the machine takes in the sufficient amount of water and detergent
automatically and sets the timer for wash and drying automatically. All we have to do is just
provide the water connection, put the detergent from time-to-time in its storage space and put
the clothes, the fully automatic washing machine does the rest of things automatically. Such a
fully automatic washing machine uses advanced Neuro-fuzzy logic technique for taking decisions
automatically. Machines with this technique uses micro programmer for their programming and
can make decisions about the type of washing to be used depending upon type of fabric and the
extent of dirt.
