Works great, easy to setup. It's my second unit for the basement level. Picks up all the fur from a large Rottweiler and a small Rat Terrier.

Not worth it
Style: L50 SES
Worked great for 5 months and then the WiFi connectivity stopped working rendering the vacuum useless. Because it’s refurbished it was past its warranty and the company refused to do anything about it other than offer a discount on a product that cost four times as much even after the discount.

Great vacuum, but it only works on 2.4 GHz Wi-Fi
Style: L50 SES
I missed the last line on the description that states in only works on 2.4 GHz Wi-Fi. I have AT&T fiber and the router they installed only runs on 5.0 GHz. The vacuum still works, but without all of the fancy conveniences. Just be aware of this and if you are not familiar with what it means, check before you purchase one. This is the only reason I am giving it a 4 and not a 5. It is my fault for missing it, so just be aware.

Great vacuum!!
Style: L50 SES
I love this vacuum. I had to work a little to get the map right for it, but it is great. We have allergies and it helps so much and saves so much time. It does take a while to do the whole house, but I have it programmed to run while we are at work and it’s so nice to come home to a freshly vacuumed house.
