We call our sweeper Bob. Bob has become a cute, reliable family member!! I absolutely love this cleaning tool. Just turn him on and let him take care of picking up around the house. It is great. It works really well...we haven't had any problems at all. I also love that when Bob goes back home, it automatically empties into the dust bag. That is a great feature. He seems to be sturdy too. My grandson was so taken with him...I was afraid he would break him...but NO....Bob just kept on going! It's great! I definitely recommend Bob!!!

So far, I am quite pleased with the Bio.  The battery charge lasts longer than my previous robots.  It's more quiet (until it empties into the bin-which I also appreciate).  It doesn't bang into furniture and doesn't get stuck.  And it seems to do a good job.  I have used both the low and medium levels. 

Worked great for about 4 months then quit picking up dirt

It's very easy to use. It sucks cleanly. Children and pets like it very much.

I really like it, it works smooth, ai love it

Love my little Bob sweep! He cleans my carpets well

Very good product. Easy to use and very durable.

We love our bio robot. He does a great job!!!' We actually call him Bob

Loving it so far. Set up was easy. I have to clean the brush after every whole house cleaning as it has a lot of hair wrapped around it. Not a big deal as its easy to remove and replace.

I have both hardwood and carpet with a dog and baby. I was hesitant to buy this but decided to try anyways. I tested it by having it vacuum and then using my regular vacuum. It barely missed anything!
