1. Advantages Of Coin Operated Washers
And Dryers In Laundromats
Public laundry facilities are very common in crowded neighborhoods of major
American cities, which are cramped for space and people don't have access to
personal laundry spaces. These facilities are very helpful for students living far away
from their families and not owning a personal washing machine. Earlier washing and
drying machines available at most of the laundry facilities did not keep track of user
time themselves, which posed serious problems to the laundry management staff in
accurately the machine usage time of each user. To do away with this problem,
laundromats have started to replace their regular machines with coin operated
machines.
The major advantages of using coin operated washers and dryers in commercial
laundry facilities are:-
1. Automated time management: Coin operated washers and dryers require
users to enter a requisite amount in coins to be able to use the machine for a
specified time. Once the user has entered the amount the integrated timer in
the machine sets up itself and does not require to be monitored. As soon as the
time expires, the machine will stop automatically and won’t resume working till
the user inserts more coins.
2. No separate billing counter is required: Since the coin operated machines
require the user to pay the usage amount in advance, there is no need for a
separate billing counter. This means hassle free payments, and that too without
long queues. This also saves the laundromat extra space for more machines and
drying area.
3. Less managing staff: Since these machines maintain records of time
automatically and directly collect money from the user, no separate billing and
time recording staff is required. Few support staff are still a requisite to clean
the laundry area and assist the users, but their number is far less than those
required in general washing and drying machines.

2. 4. Promotes self service: Coin operated washing and drying machines are very
similar to automated mini soda vending machines found in public places like
airports, shopping malls etc. Such vending machines operate without any
human surveillance. Same is the condition with automatic coin based machines
in laundromats; they also don’t need any human surveillance.
5. More savings: Though the initial cost of coin based washers and dryers are
usually higher than the general ones, these machines prove to be more cost
effective than the latter ones. This is because of the lower number of staff
required to smoothly run the laundry facility.
