If you plan to buy new washing machine I have few tips for you.
Think about this first.
1.Do you already own one? Need to upgrade.
2.You are buying it for first time.
3.Your budget.
4.Water supply in your house
5.How many family members do you have?
Ok suppose you have made the list of info I have asked you. Also make a note of these points.
1.Do not go for brand blindly.
2.Do not go by ad campaigns.
3.First ensure if you really need it.
Basic thing you should look is water supply in your house if you have free water supply and can use 500 or so liter of water for washing clothes you should go for front door large washing machines which use direct water line for supply. This should be appropriate if you have 6+ members in your family and you also wash linen in you home only. If you are 2-3 people and have free water supply you should go for single door automatic washing machine. Now considering the above two options your budget does accommodate the above advise I would ask you to by independent double tub washing machine. This is also true if you have fewer water supplies.
Now coming to machine how to choose from different brands. Machine power is important. Most of the ads mention hi power or turbo power or heavy duty, do not trust them, read the wattage written on the back of it. Do not go for machines with 240 -280 wattage. Small machines should have 350+ wattage and bigger machines should have 500+ wattage. I have seen several people who buy in hurry and repent later about shortage of water supply and High cost of washing in small families. Happy Buying/Washing!
