Bests & Worsts Reviews from Amazon

Background: Let me first start by saying that I have owned two Roomba units before this (first a low end Roomba and then a 800 series Roomba that I paid $600 for and broke after two years). Because I was frustrated by how quickly my expensive Roomba broke, I next bought a much cheaper Ecovas unit for $200. I found the performance of Ecovas to be inferior to the Roomba (unit got stuck more often) so I decided to try the newly released Shark unit (which I ordered directly from Shark's website). Shark Review: Overall, I think the Shark 750 is clearly better than the Ecovas unit I currently own and similar to Roomba quality. Actually, the Shark unit offered improvements to my Roomba in a few ways. Navigation: I found that the Shark unit had the right height profile to avoid getting stuck under furniture (similar to Roomba). The Ecovas was getting stuck under my kitchen cabinets, certain parts of bed frame, etc. There were a few times where the Shark seemed to get stuck, but it wiggled around for a while and managed to free itself. The Shark also seemed to be able to navigate this super thick rug that my dog uses. Cleaning power: I have hard surface floors (mix of wood and tile) and a 2-year old lab that sheds a lot. I found the Shark to be quite good at picking up dust / hair. The shark dusk bin has these pointed edges which I think reduces hair tangling for long hair around the brushes. The 800 series Roomba unit has these tangle free rollers which you can pull the hairs off which I like a lot, but I am not sure if it is worth $600 vs the $350 Shark. Side brushes: The Shark unit has two side brushes compared to only one on my old Roomba unit (I guess two is better then one). The Ecovas unit also had two side brushes, but I found the bristles tended to tangle. The Shark unit has 1 long strand and 2 short strands, which looks a bit odd, but I think helps avoid tangling of bristles. Magnetic tape: This was something new that I did not have with the Roomba or Ecovas. The Shark unit comes with magnetic tape to zone off unwanted areas. I have these electric cables under my desk that the Roomba and Ecovas would always get tangled and drag around. I zoned off the area with the tape and it seemed effective at keeping the Shark unit out (see picture). It is not the most pretty thing, but I'll take it over having to untangle the cords from the vacuum. (Note I used up all the tape they gave me so if you have a bigger section or more areas, you'll have to buy more tape). Mobile App: The mobile app worked fine once I connected the Shark to the wifi. I was able to schedule cleaning sessions right from the app. (Note, I did have some trouble connecting to the wifi initially and had to try a few times). Conclusion: For $350 (what I paid), the Shark 750 gives you similar performance to the much more expensive $600 Roomba unit that I had before and significantly better performance than the $200 Ecovas. I also like the magnetic tape solution to zone off the electronic cables.
