Clean & Empty Cordless Vacuum Cleaner with Auto-Empty System, Lightweight Anti Hair Wrap Vacuum with Pet & Crevice Tools, 40 Mins Run-Time, Charging Dock, LED Headlights, White/Blue, BU3521UK

I’ve been using Shark vacuum cleaners for years and have stuck with the brand ever since making the switch. My previous Shark lasted for years, so I had high expectations for this model, and it hasn’t disappointed. This vacuum is incredibly lightweight, making it easy to carry and manoeuvre around the house, yet it’s still impressively powerful and picks up dirt with ease. The self-emptying feature is a little loud when emptying, but the convenience more than makes up for it. Overall, it’s a fantastic vacuum cleaner that combines power and ease of use. Excellent value for money and another great product from Shark.

Extremely easy to use and has made vacuuming a pleasure! My teenage daughter actually offers to use it 🤣. Love the fact it empties into the box instead of having to empty into a bin each time. Powerful suction and it picks cat hair up well. It rolls well into corners. It’s light to use the easy to take apart and use attachments. This was expensive but compared to others of similar price, I rate it higher by far. It has limited time without recharging. I do 3 rooms and the hall and it goes down to 3 bars (half ish).

This makes cleaning the house so much easier and regular. Light and so easy to adjust from hard floors to carpet. Picked up things my old vacuum left behind. Anti tangle technology doesn't get clogged up with pet hairs. Good for tall people feel like I don't have to bend while using it. Nice that extra battery can be purchased and charged separately so you can increase the 30-40minute run time. The devices fills up quite easily but then attaching it to the stand empties it quickly and means emptying the main bin compartment more regularly stops it getting blocked up or jammed.

Perfect, easy to lift. It charges in my cupboard and is always ready to use. Light to use, good for daily/weekly run around. Turns effortlessly to get in corners and awkward spots. Lifts fur from upholstery reasonably well with the attachments. Drawbacks: Suction a little lower than my old vacuum and sometimes it does not auto-empty and needs to be opened up by hand. The base unit takes a lot of dust before it needs emptying. The base unit is pretty straightforward to remove and empty. The vacuum comes with one filter in it, I would advise having a spare. They can be washed, but a spare is needed while the other one is drying.

Very easy to put together and the suction is a lot greater than my previous cordless vacuum. The fact that it keeps itself fully charged and empties itself is a bonus. The cleaner and docking base doesn't take up much room which is a bonus.

I have used it for a month since the purchase. So far, can't complain! The suction is good and the battery life is sufficient to clean my flat (about 40sqm). The auto empty system as well as the standing dock has been super useful, keeping my vacuum to constantly be charged. Other functionality wise, it is a little basic, but still the whole package I think - auto/eco/power mode, light in front of the main head, battery level is shown as 4 blocks. The downside is, it is a little loud I feel like compared to the other vacuums I have used. The auto empty functionality can be a little loud as well, but then again it's only for a couple seconds and you can turn it off as well. Overall, for the price point, this is a great cleaner compared to the other knock off dyson/shark brands in amazon.

Its good, battery could be better. Bought as apparently great for pet fur which is not the case. I have to mamually unblock daily

I have had this for a year now and can give a fair review. PROS: Excellent performance, I had a Dyson V8 pet before and this really out performed it. 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 well No 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
