I’ve had roombas since they came out over a decade ago. I have been wanting to upgrade to the newest Roomba that had the dust storage bin as well, the idea of only needing to empty my vacuum dust bin about once a month versus every other day was very appealing. I started researching and saw that shark also offered a monthly dust bin, and this dustbin did not use filters and bags, meaning that there would not be near as much waste involved. The one thing I hate is when a company sells you a product that makes you buy more products to continue using the original product. So I decided I would go with the shark so I wouldn’t have to buy dust bins for the Roomba. Boy, was that a mistake. First off in tests they say that the shark had a better suction than the Roomba, but they failed to mention that the shark only has the better suction when it’s in max mode, and you also cannot have the shark automatically go into max mode with cleanings, you have to go into your app after it started cleaning and manually change the suction mode from normal to max. In addition it cannot clean carpet or rugs worth it’s life (even in max mode)- I still have to pull out my vacuum to vacuum my main rug in my living room weekly or every few days, or what I’ll do now is pull out my old roomba which I have stored in my office and I’ll bring it to vacuum my main rug since the shark does such a p*ss poor job. I also have to now keep bedroom doors closed when I leave the home because the shark will always lock itself in the bedrooms, I’ve never had this issue with a Roomba in my life, and it kind of defeats the whole purpose of leaving the home and having a vacuum clean for you, if you have to leave several doors closed so it can’t go in the other rooms to clean while you’re away because it will lock itself in the room and then die. Speaking of dying, this shark regularly dies before it gets back to its charging base, when it doesn’t lock itself in rooms. Of all the times it leaves the base to clean, which I have it set on the schedule to clean every day, it probably returns to the charging base about 5-10% of the time. I normally find it dead somewhere in the hallway or under one of the beds that I have a paint can holding the door open to so that the shark won’t close the bedroom door and lock itself in there. Honestly I would pay double the price of a Roomba at this point knowing that it would be a better vacuum than the shark. I recommend staying away from this cheap imitation! Even worse, even though I’ve only had it four months shark is refusing to do a return for me. The customer service has been extremely unhelpful and told me verbatim that they don’t stand behind their products and won’t offer a return. I mean that’s more than enough proof, and I wish I had recorded the phone conversation so I could let others know just how bad this company is to work with. They clearly don’t stand behind their products, and don’t care of you know it or not. Buyer beware!!!
