The advantage of purchasing from Hammacher is that they offer a 100% Unconditional Lifetime Guarantee on everything that they sell. The Scooba 450 normally comes with a 1 year standard warranty, but if you purchase it from Hammacher Schlemmer and you ever become dissatisfied with the Roomba for any reason, they will replace it or refund the entire purchase price, whichever you prefer!
Some other retailers may offer a very limited conditional warranty and call that a 'lifetime guarantee'. Read the fine print and don't get fooled! Hammacher is the ONLY retailer to offer a 100% unconditional lifetime guarantee, absolutely free of charge.
