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. Review: Love this! Best hoover I have had. - 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). ## Features - AUTOMATICALLY EMPTIES ITSELF: Completely sealed bagless base holds dirt and debris for up to 30 days, so you can forget about emptying for weeks at a time.

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.

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. --- ## 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.hr/products/723030657-clean-and-empty-cordless-vacuum-cleaner-charging-dock-bu3521uktsb](https://www.desertcart.hr/products/723030657-clean-and-empty-cordless-vacuum-cleaner-charging-dock-bu3521uktsb) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-08-05*
