Once you start a front-load washer, any forgotten socks or other items will have to wait until next time. After that door closes, you're locked out for the duration. With a top-loader, you can collect items dropped on the stairs or down the hall and just lift the washing machine lid and add them at your discretion. It might be a long wait between loads using a front-loading machine, too. A front-load washer can take over twice as long to finish a load as a high-efficiency top-loader. If you want to keep laundry day down to a few hours between shopping chores, 80 to 100 minutes per load may start to feel like an inefficient use of your time.
