  • Just what we needed

    a long haired cat and a short haired dog. This picks up everything, and neither animal even bothers with it.

  • Love love love my Roomba

    It's so nice coming home to clean floors daily. This little machine picks up fantastic! Every now and then I have to dock it myself, but it does an amazing job! I have an electric doggy door and dogs bring in little dirt and little pieces of grass daily... So nice to come home to clean floors!

  • Second roomba

    I bought one four years ago because I was post op breast cancer and had a big clunky upright vacuum, but im still using it today. Works great and I run it everyday to keep everything tidy. I bought this one for my inlaws because they just bought a ranch style home to retire in. They are absolutely in love with it and its performance.Another satisfied customer.

    I love Roomba 770. I first owned the 650 but that had a terrible accident involving a dog!! ??(The dog was not hurt) so when I saw the 770. I feel like in love w/ the sleek design. I have dogs and it does very well picking up all their hair and dirt.. The reservoir space holds a lot more and needs to be empty a lot less( even though I still empty every day) and the battery lasts longer then the 650.I love the hepa filter, it works great ..some reviews say it's quieter but I don't think so.

    With two rescued pugs and 1 frenchie, and two medium parrots I found myself vacuuming 4×'s a day. With this amazing guy I have more time to spend on other things. Its amazing and picks up better than my Shark vacuum. WOW! Its expensive and I wouldn't usually purchase something like this honestly but I was at wits end with dog hair and feathers (hence vacuum 4+ times a day). All in all I would buy another!!! Love it!

  • No more pulling out the heavy vacuum everyday!

    So in love with the 770 Roomba. I first ordered the 660 and didn't care for it. It was loud, always stuck on something and was a bit bulky to get under some furniture. The 770 has met my expectations and much more. Less noise, (my son described the 660 as a Mack truck going through the house with the noise!) glides right over wires and rugs. So slim it amazes me what it goes right under. I have a dog that sheds constantly and this has saved my sanity. The tumbleweeds of dog hair rolling through the house would make me crazy and running for the vacuum to only find more the next day. I set the Roomba to run at night and I wake up to dust and dog hair free floors. Remote comes in handy but not necessary, I could of done without. I would love to see how well the 800 & 900 series work. Maybe it will be my next splurge. If they're better than the 770, it would totally be worth it.
