First, I nicknamed my Ultravision Robot, Bob. Bob is remarkable. Before he arrived, my husband was saying it will never make it over the rugs %26 thresholds. He was WRONG! There's not a rug or threshold Bob can't handle. I mean not 1! And some of ours are pushing 3/4 of an inch high! I want to add that we have 3 large dogs and 5 cats, so Bob's work is absolutely cut out for him in our home!
Things I love about Bob:
1.When his battery is low, he returns to his station, empties himself out, then charges.
2. His sweeper brush does remarkably well to sweep dirt away from edges so he can vacuum it up.
3. He goes under our couch and ottoman to thoroughly clean where I had a tough time manually vacuuming before, and I hate moving that heavy chaise/couch sectional!
4. I love the way the app tells you that something is wrong and how to fix it!
5. I LOVE that Bob returns to his station when something is wrong.
6. I love that Bob has never gotten hung up at our thresholds or rugs.
7. I LOVE that while Bob does his thing cleaning my floors that I'm able to do whatever!
8. I love that Bob can also mop! If he leaves a tough spot behind, it's wet, and I reach down, and it wipes right up.
8. When errors do occur, the fixes are quite easy. For example, if the error says the main brush needs cleaning, it literally takes me a minute or so to access it and remove the excess debris wrapped around his brush.
Now regarding Bob's imperfections:
1. After he empties himself 2 or 3 times, he typically requires a manual dump of the dirt as some can clog the exit emptying port. But a simple fix is after a few self emptying, to open him up and make sure he's completely empty, and then I do a quick check of his filter %26 main brush to proactively clean them. But the good news is that if I forget to do the very quick pm, the app will notify me that the main brush, dust bin, filter, or sensor needs cleaning.
2. There's 1 nightstand that's high enough for Bob to go under, but because there's a small area on his topside that's a little higher than the rest of him, he can get stuck under that 1 end table. The good news is that the app let me know he was hung up! Thus, when I run Bob, I block his entry to that 1 nightstand.
3. The only other imperfection, in my opinion, is I wish his battery lasted longer, as I wish ALL battery operated equipment lasted longer!
I am 100% thrilled with the Ultravision BOBsweep. Bob saves me both time and energy! In fact as he works his way around my home cleaning, I repeatedly am heard saying "I LOVE Bob!". One day my husband said, "You tell Bob you love him more than you tell me!". Lol
In short---
I LOVE BOB!
