The pump allows me to skip emptiying the bucket twice a day. I ran the discharge hose to the AC drain, so it runs unattended. Easy setup, nice looking. It has to work almost fulltime to keep a 2,200 sq foot appt at 50% humidity, so I am not sure is a large enough unit. I have a second unit (Sears), helping out.I am afraid that after 18 months, the pump stopped working, so I can't use it anymore. Warranty is over after 1 year.
