Time for me to jump in the wash since the water is warm!
So you have a large family?
OK!
You are on septic?
Yes, great!
What is the largest bedding in your house?
Is your current dryer working?
If it is, no need to upgrade unless the units are in view like off the kitchen, family room or under 7.3 cf!
Some things are often overlooked and the little things makes a huge difference!
I've own the Electrolux Wave Touch since 2009 and by far it's the best machine I've used in my life!
So far no repairs and only once the machine did not spin a load because it could not balance which was about 2 or 3 weeks ago!
Now keep in mind that the drum tilts 10* towards the rear so keys, coins, toys will stay in the drum without getting caught between tub jamming the pump!
Water temperature is flexible and most normal soil wash loads can be done in 1 hour 10 minuets give or take!
The newer Wave Touch machine has steam and add more water button but it's not needed if you use the right amount of detergent and cycle according to soil level and load size!
I'm not going to debate what MFG the best but the link below will let you see the difference between TL and FL when I got my Electrolux.
Here's a video I've posted how a shirt goes from front to rear of the tub:
Good luck on your purchase!
