Used product for less than 60 days and it's dead

Ordered this vacuum on January 31. I was vacuuming an area rug and it stopped working on March 31. 60 days of product use and already a break down leaves me less than impressed.

powerful but heavy!

I bought this about a year and some ago. This thing is powerful and quality however, the one major con is how heavy it is. I don't have very good wrists, so I am giving this away. Also terrible with stairs. When you want to use this as a "stick" vac, beware that it is bulky and you will have to deal with holding and moving the canister with you almost every step of the way or it will topple over

SHARK IS A DISAPPOINTMENT

HORRIBLE MODEL! SHARK HAS REALLY GONE DOWNHILL!

Shark really disappointed me with this “new” model! Suction is horrible!!!! It’s heavy and the cord is stif. I’d rate it zero stars if I could. Miss the uv700 model. It was worth every penny. And of course shark has several patents on their duo clean feature so no body else can offer that feature. Shark used to be my favorite brand but not anymore. I clean houses and go through at least 2 vacs a year. Congrats shark. You just lost a good customer

Overheats in 10 minutes

This machine is a great design but I can't recommend it. Every time I use it, it overheats after just one room. I have to wait for it to cool down before I can continue. It's going to take 2 hours to fully vacuum at this rate. I love these products. They are usually thoughtfully designed. This one has to go back.

Buyer beware…

Piece of JUNK Bought this vacuum to replace our other Shark that had worked flawlessly for 8 years - just wanted an upstairs and downstairs due to the amount of carpet out new home has compared to our other. Straight out of the box, first run, tried to vacuum the hallway (30 ft) can’t get halfway before it hits the red light and needs to be”cool” down Wait a day. Don’t use the power detector, just the carpet setting for a 10x14 room. Surprise surprise can’t even finish the room without the red light thermal Vacuum smells like it’s burning, both rollers are moving. Check for clogs like the online FAQ states. Clean and clear. It’s just a plastic piece of junk Don’t waste your money. shark used to be about affordable quality - now it’s just crap. Can’t wait to see how the 5yr warranty dog and pony show will go.

Disappointed long term customer.

I replaced a 10 year old Shark vacuum with this one. I loved my old one this new one not so much. I will say that it does have very good suction. That is where my love ends. The brush head is thicker than my old one and does not fit under some furniture. The electric cord is very stiff and cheap feeling, I’m sure it will develope cracks over time. The suction hose is too short and stiff. This makes it awkward to use the hand attachments without tipping the vacuum over or holding it with your free hand. As I stated the hose is stiff and it is helpful to use two hands to control the beast. The on/off and suction select switches are poorly positioned with zero thought put into actually using them or bumping them inadvertently. The upholtsery attachment pivot point does not have enough friction to keep it from flipping over if you move it side ways or at odd angles. I expected a lot more quality for the price paid. As I said earlier, I loved my old one for 10 years; I am incredibly disappointed in this new vacuum. If I could return it because I don’t like it I would, but I don’t think it should be Walmarts problem that I hate this vacuum. So I’ll continue to use it until I can afford another vacuum and send this one to the dump.

The dirt detect is not a very good function. Only had the vacuum for about a month and the dirt detect stop working properly. I kept it clean and maintained it properly. Had to reorder a new one and will be returning this one, hopefully this he next one doesn’t do the same thing. Wish there was no dirt detect i do however really like the floor and the side detectors, they work well.
