To choose a new washing machine that meets the requirements, we need to compare the specifications of the available options with the details of your old washing machine.
First, we need to check if the new washing machine can hold at least 6kg, which is the capacity of your old machine. Let's go through the specifications of each machine:
1. Aqua - £299 - 5.5kg - 1200 - 0.9 - 42
The Aqua washing machine has a lower capacity than your old machine. We can exclude this option since it does not meet the criteria.
2. Bubble - £399 - 6kg - 1600 - 1.2 - 45
The Bubble washing machine has the same capacity as your old machine and a higher spin speed. It meets the requirements.
3. Eco - £259 - 6kg - 1000 - 0.9 - 44
The Eco washing machine also has the same capacity as your old machine, but it has a lower spin speed. However, since the requirement is to have a spin speed at least as fast as the old machine, we can still consider this option.
4. Optus - £329 - 7kg - 1400 - 1.3 - 50
The Optus washing machine has a higher capacity than your old machine, so it meets the requirements. However, it has a higher spin speed and uses more electricity and water per wash.
5. Swirl - £329 - 6kg - 1100 - 1.1 - 49
The Swirl washing machine meets the requirements in terms of capacity and spin speed. Similar to the Optus machine, it uses more electricity and water per wash.
Based on the specifications and requirements, the most suitable options are the Bubble and Eco washing machines. Now, you can further narrow down your choice by considering other factors such as price and additional features offered by each model.
