As I have two cats this was chosen to deal with the shedding and it handles this task like a boss.I have carpet and hard floors I have no problem as it automatically changes suction to deal with both. Very versatile and cleans wellNo cords to wory about and the battery life is very true to time cleaning. I get around 30 minutes full power. 40 minutes on Eco power.LED indicators lets you know how much battery you have left. You also can choose different cleaning modes on the handle area on a press of a button.Very easy to take out filters and de-asemble to clean. Really like that it has little buttons to clean the entire vacuum for good maintenance. Quick and easy.The clean and empty feature means no need to be fiddling with emptying the Vacuum manually.Its very light weight and easy to move around/ carry.Amazon sells all the required Shark filters so I got a 4 set and stocked put. So while filters are clean/ washed and drying I can use a new one without waiting.CONS:You will need to empty vacuum by sitting it on the clean and empty cradle often while cleaning as the cup will fill quickly as its small but not a problem just a thought to keep in mind if you have a large home. However thats quick just place it on the stand and it suctions out in seconds.You must have the moon lit botton off to empty the vacuum. If the moon lit botton is on that's the quiet mode setting and it will not empty vacuum it you sit it on the stand with it on.Cleaning the filters - I would say to wash these every month or so if you use the vacuum every day or 2 days like I do. I had this for 1 year and I only just cleaned all filters in the Vacuum and the dust collection bin. There are 3 fillers in the dust collection bin, 2 sponges and 1 HEPA filter. In the main vacuum there is one HEPA filter. So 4 in total. Dish liquid and a dish brush can be used to clean HEPA filters. Let them completely air dry before re-inserting them in the Vacuum. The cleaning can be around 30 minutes depends on how dirty your vacuum is. There are little buttons on the Vacuum and the empty bin to get to the filters. Its very easy to take each part apart to clean.Overall excellent product I will recommend it and will also stick with any version of the Shark clean and empty. I am extremely pleased with this product. 10/10 ### ⭐⭐⭐⭐⭐ Worth Every Penny 💰 *by on Reviewed in the United Kingdom 10 September 2026* I love this. It’s so much easier than dragging a clunky, heavy, corded Dyson around. It’s very sleek to look at, and it auto-empties after each use, in the bin at the base of the stand. It cleans really well, with different suction levels. I love that I no longer have yards of my hair wrapped around the bristles. This picks up everything without using bristles. It cleans really well. Not too noisy, and the attached battery charges really quickly. Best of all is that it’s so light. And it doesn’t need plugging in. Haven’t tried the attachments yet, but there are plenty provided, and a bag to keep them all in. ### ⭐⭐⭐⭐⭐ TWO MONTHS AFTER PURCHASE *by on Reviewed in the United Kingdom 21 August 2026* Love this hoover, the auto-empty feature is saving so much time it is so convenient and helps you to keep the hoover as its best as you can empty it effortless after each floor ensuring it runs at its maximum potential. The emptying of the waste tank is also super easy and does not get your messy. The noise level on eco is very quiet however if you hoover on power mode or carpet mode it can be quiet noisy however that is normal as the hoover is very powerful so it is expected. Battery on the other hand is only downside so far is the battery life it might be ok if you live in a flat but for 3 bed house it might be not enough to do the full run at once however upon further checking I have found that you can purchase additional batteries. Two batteries would be perfect so you can switch halfway through.The docking station and the hoover itself look very stylish and would fit any house well in my opinion. Docking station filters as well as hoover filters are easily removable and washable. You also get 5 years warranty from Shark so it is very solid choice and value for the price! --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.fr/products/723030657-shark-clean-and-empty-cordless-vacuum-cleaner-charging-dock-bu3521uktsb](https://www.desertcart.fr/products/723030657-shark-clean-and-empty-cordless-vacuum-cleaner-charging-dock-bu3521uktsb) --- *Product available on Desertcart France* *Store origin: FR* *Last updated: 2026-09-24*
