This is the second season I've used this rug. (was stored away for winter) It's used on a front porch, full sun all day.  The colors have held up well, no worn areas and it sprays off easily with a garden hose.  No stains, so far.  My dogs love to sleep on it and hair does attach rather a lot.  I generally vacuum it to remove and try to discourage them lounging on it. (hasn't worked) I really like this rug and it makes the porch a cozy, bright and colorful place to hang out. Highly recommend
