Horrible

So far it's horrible. Doesn't hold it's charge. Fully charged and it maybe lasted for 10 min. Hardly sucks anything up. I'm seriously considering on returning this thing.

Hi there, Thank you for sharing your feedback. Experiencing a vacuum that only runs for a few minutes on a full charge and barely picks up debris would leave anyone frustrated, especially when you expect strong performance right out of the box. Your experience so far doesn’t reflect how this model should be operating, and it makes complete sense that you’re considering returning it. To help address the battery and suction issues you’re seeing, we’d recommend checking our self‑help guide here: https://support.sharkninja.com/article/IW4000-Series-Shark-Cordless-Detect-Pro-Vacuum-Troubleshooting-Guide?redirect=false. If the troubleshooting doesn’t improve performance, please follow the instructions at the end of the guide so our team can assist you further. Kind Regards, Shark Clean US.

Totally disappointed

I was so excited when I got this to help in the kitchen with all the dog fur. I am so disappointed. It barely has any suction. I have to go over areas multiple times, slowly and even still, fur/crumbs left behind. It only seems to suction when moving forward, not back.

Meh! A bit disappointed.

I am generally a fan of Shark vacuums. I already have 3 (a robot, and 2 lift-aways). So, when I wanted to go cordless, I thought of Shark first. I bought this Shark Detect Clean & Empty system about a month ago. So far, I am kind of disappointed. The suction is kind of sucky, as in it has very little power. It is a little heavier than I would like for holding it up to the ceiling to suck up dust-bunnies. If I use one of the 2 attachments, the sucking power is even worse. It is also a PITA to have to carry the attachments around with me as I clean. They do not attach to the vacuum and only one of them attaches to the base. AND, speaking of attachments, why can't Shark use a coordinated system where all attachments fit all (or most) of the vacuum styles??? I have some attachments from my older vacuums that I absolutely love. But, noooo, they can't be used with any other model.

Good for daily small jobs

We have had a Dyson V7 for years and needed an economical replacement. Chose this one because of the auto empty feature on the base. I use this vacuum daily for limited jobs. I like the auto empty feature and the lighted brush roller head. There are two less-than-perfect details. 1) the auto-empty only works if you have the motor on the floor wand. If you use a handheld attachment, you have to swap back to the floor attachment before you can lodge in the base for the dirt canister to empty. 2) I vacuum a lot of crystal cat litter. The crystals don’t transfer fully when emptying, and they will get hung in the back “gate”, requiring me to use my hand to clear the crystals and close the gate before using the vacuum again. My husband has said he wishes the power button was a trigger rather than a push button on the back of the motor requiring two hand operation - but I’m not as bothered by that. Suction is good.

Love the auto empty!

Lightweight and suction seems amazing and I LOVE that is suctions out automatically from the canister after every vacuum when you put it back on the dock without my hair getting all clogged in there. I can probably empty out the dock/base once every blue moon.

Dirty, useless vacuum

I can not say enough bad things about this product! This is the worst vacuum that i have ever purchased. It does not pick up dirt, the door on the head doesn’t shut well, it spews dirt out the top and is very difficult to clean. I have to clean it after every use or it doesn’t work. This was purchased a month and a half ago and yesterday it went into the dumpster. This is a dirty machine that does not function well! This is the first time i have ever left a bad review on any product that i have owned. I have never owned a shark in the past and never will again.

Useless

We received this vacuum as a gift from my parents for Christmas. We don’t use it often, but recently have noticed it just pushes dirt and hairballs around. It does not pick up. If I lay the vacuum right on top of these things, it will initially suck it up and then leave it behind once the vacuum turns off. And to top it off, it clogs constantly. I don’t know why I even bother using it. I end up having to pull out my big Dyson and just suck up everything this leaves behind. Very disappointing because I’ve heard great things about Shark from people.

Junk

I started using this vacuum in November. I have already had to have the handheld part replaced. The vacuum suction does not work. It’s seemingly sucks things up and then dumps it all back on the floor. I just started using the new handheld that was sent to me And the vacuum is still doing the same thing except for now when I use it in boost mode, it turns off in about 20 seconds. The eco mode doesn’t suck anything up and boost mode sounds clangy and loud and then shuts off. This vacuum is not worth the money. This vacuum is not worth any money!!! I don’t think I will buy shark again.

Wouldn’t recommend to anyone!

If I could give it 0 stars I would! Extremely disappointed in the amount of money I spent vs. the quality of the product. When I first got the vacuum I thought it was great. That lasted about a week. I am a person that was interested in this because I love to vacuum everyday and having something cordless was very appealing. I don’t even need to vacuum everyday, but I love an extremely clean home. It seems that after the first week, the suction on the vacuum steadily decreased and in order to increase suction, you would need to put it on a boost mode which only kills the battery extremely fast! I am at the point now that I can only vacuum on boost mode, and my battery is now dead within about 15 mins. I went to purchase a new battery and it says it is sold out online! Absolutely terrible! I am extremely disappointed, especially as a dedicated ninja customer who has spent thousands upon thousands on their products!
