Our old Shark was dead but now it lives again!

The wife had an old Shark that had a dead battery. I could not find the OEM battery for it anywhere. I got his battery, changed the plug on the end and her Shark now works like new. Good battery so far and I hope it continues to work like it is as it saved us a lot of money by restoring her vac to running condition.

Thank goodness for our new robot!  This is the exact one we got when we put in our pool and it lasted about 4 years.  We keep our pool open year round.  This little thing is awesome and now has our pool all beautiful and clean again!  My grandson loves to watch it sweep across our extra large pool.  Awesome product!

I love this vacuum! The only problem is that my dog knocked over the vacuum and it fell on it's side and broke the plastic u shape connector that goes from the vacuum to the hose. I tried to get the part online and couldn't find it. I called shark to get the part and they do NOT SELL THE PART! I was told that I had to by a new vacuum! The part couldn't cost over $5. There is nothing wrong with the vacuum, every thing is great just need that part. Because of this I would never by another shark again!

After five years, my poor Roomba was barely able to run for five minutes at a time on a full charge, but I popped this replacement battery in and it was almost scary how much livelier my Roomba became.  It can even vacuum rugs again!  The extra brushes are a nice touch but the battery speaks for itself.

I have owned this Shark for 1 full year and it has been a beautiful, wonderful gift to our family. From the sucking-technology to the hose to the easy empty canister to the washable filters. Just recently, the vacuum setting stopped working. I have emptied the canister and washed all the filters. The device that turns is free of debris. Can Shark assist me at all?

***UPDATE--- they helped me! Troubleshoot over the phone using the phone number from the user manual and when there was no resolution, sent me a pre-paid label and sending me the replacement part at no cost to me!

Perfect fit for my Shark vacuum.  I'd blown out the existing filters with compressed air and washed the foam a few times, but that never quite got me back to the suction that the machine had when new.  I did that because the filters are hard to find in brick and mortar stores.  The new filters got me back to that level of satisfaction..  Two thumbs up.

Wow!  Our tank went from pure green, we could not even see our fish, to crystal clear.
Thank you Green Killing machine, you are amazing!  It is so nice to see our fish again: )
We have a 29 gallon tank, btw.

This battery was for our shark sweeper that is several years old. Every indication was that the battery had reached the end of it's life. After ordering this battery, I determined the mail problem was with the beater bar. After replacing the beater bar, the new battery gave the shark sweeper new life.

We have a beta, this looks great, and the fish seems very happy, plenty of room (more than the vase we had him in before!)

We have had our Kirby vacuum for nearly 18 years. We also purchased a Dyson Animal D41 back in 2012. The Dyson has been in the repair shop three times since and is currently broken. The Kirby's transmission went last week. So, I bought the Shark, based on reviews. I am NOT disappointed. It is working so well, our carpets look brighter. My husband and kids like it so much, they have been vacuuming without being asked. I am not making this up! I am quite impressed with this vacuum and since it was priced SO reasonably, I will be thrilled if we get a couple of years out of it. :)

We used to own a shark until it gave out about a month.  I thought this would be about the same with a little extra power but it is a completely different cordless!  It is incredible with the spills and messes it can clean up and the boost of power works very well.  It works for long enough to get quickly around a house of about 1400sq ft before needing a recharge.  Excellent if you want a cordless!

Love these. They fit my shark amazingly and work better than the ones that came with it originally;) all this and way cheaper than buying the actual replacements. Win win!

My carpet sharks love them so much they stashed them immediately. So their toy box is still empty, but their stash has something in it besides my keys! Win Win?

I absolutely love my new Shark. I have two dogs and lots of carpet. Works perfect and good on stairs too. It's also one of the quietest vacuum's I have owned. I highly recommend!

Nice replacement for the original battery in our Shark cordless vacuum. The originals would no longer hold a charge and ran the vacuum motor at a reduced speed, hampering suction. We're back in business. Lightning fast free shipping.
