Shark Clean & Empty – Lightweight Cordless Vacuum Cleaner with HEPA Filter, Portable, Rechargeable, Auto-Empty System, Stick Vacuum for Pet Hair, Carpets & Hardfloor, White, BU3521ME, 5 Years Warranty

If you’re considering a wireless vacuum cleaner, this is hands down one of the best investments you can make. It delivers powerful performance, especially on carpets, picking up dirt impressively well. The battery life is long enough for practical, everyday cleaning, and the whole unit is lightweight and easy to maneuver. What really stands out is the thoughtful design and ergonomic build — everything feels intuitive and well-balanced. Based on my experience so far, it’s a purchase I feel confident about and would recommend to others.

Absolutely amazing vacuum, light weight in comparison to traditional vacuum. Slow to charge, but charge lasts quite awhile. Daily use in small one bedroom apartment, charge lasts about two weeks. Great attachments, easy to disassemble for cleaning purposes, great suction.

The Vacuum cleaners did good job on daily cleaning work. For my flat which is only 369 sqft, it can completely the work in one-time full charge. However, if I want to do extra cleaning, then I need to charge it again. All about this vacuum is good, except the battery is kind insufficient. But if you live alone or having a small apartment then this is the most affordable and valuable vacuum cleaner I recommend.

Love it! I bought second already for my second apartment. Works great! It's my 3rd Shark Vacuum cleaner, and eac new vacuum cleaner is better, better and better. Light, great suction power, removes my animals fur easily. If you find it on sale, buy it! You won't regret

As a user of proper vacuum cleaners I was skeptical about cordless vacuum cleaners. Unfortunately my experience proved true. As soon as I got it I tried to vacuum a strand of hair and wouldn’t come. I felt like I am holding a fan not a vacuum. I tried vacuuming the tiles, I had to go over the piece of crumble four times to pick it up. Then I tried to vacuum my carpet, the vacuum showed red light and shut off and the battery which was full became zero. This is a toy not a vacuum.

I am very happy with my recent purchase! It's incredibly light and easy to use. I particularly appreciate how it automatically adjusts its power based on whether I'm cleaning a floor or carpet. What I love most is the stand station. It's so convenient not having to fix it to the wall, and the auto-cleaning feature is a fantastic bonus. Beyond these features, the 5-year warranty speaks volumes about the quality of this product. I absolutely recommend it!

Should have purchased this long ago. Really happy with the options. The self cleaning or dust extraction is really a game changer.Wow.

Heavy to work with. Filters need a lot of cleaning. Broke after 12.5months

What I received was an opened box with a used item inside.

Ich habe lange gesucht,gelesen und informiert. Da mein normaler Staubsauger kaputt gegangen ist und mich das Kabel immer genervt hat,war ich am überlegen ob ein Akku Staubsauger für mich im frage kommt. Wichtig war für mich: 1. Preis 2. Akku Leistung 3. Saugleistung 4. Lautstärke 5. Flexibilität Dieser Akku Sauger hat alles! Aufladung 100% geht sehr schnell. Ich habe 80qm Wohnung, 3 Zimmer. Ich komme mit einer Akku Ladung komplett aus. Das war ausschlaggebend für mich .Ich habe Laminat Boden und in jedem Raum Teppichbrücken. Bei Teppich stelle ich die Saugleistung auf 3,da zieht er natürlich sehr den Akku. Aber, wenn ich die Wohnung fertig gesaugt habe und ich sauge nicht nur Oberflächchig, sondern nehme Teppich hoch oder stelle Stühle zur seite usw.,habe ich zwischen 10 und 30% Akku noch über. Manchmal lasse ich ihn an und stehen wenn ich was hochhebe, dadurch den unterschiedlichen Akku Stand. Auch was der aus dem Teppich zieht ist enorm (Foto von 1x saugen). Bei mir wird in der Wohnung nicht mit Schuhe gelaufen und dennoch zieht er den Staub/Dreck usw.raus. Auch das er die Düse hat um in Ecken zu saugen ist top. Die Reinigung ist einfach, schnell ob Behälter ausleeren oder unten die Rolle mal reinigen. Die Lautstärke ist normal, nicht zu laut, sondern Standard. Ich bereue nicht im Ansatz diesen Akkustaubsauger gekauft zu haben. Ich kenne den Dyson und andere Marken die extrem hochpreisig sind und können nicht im geringsten mithalten. 100% Kaufempfehlung!!!

I bought this to keep the area around my rat cages clean, because love to kick their bedding (hemp and wood shavings) everywhere, requiring vacuuming at least once a day, and my previous vacuum wasn't keeping up with what it needed to suck. No such trouble with this Shark though! It sucks up hemp chips and wood shavings like a champ! The auto-sense works perfectly and adjusts the power necessary in that area with no issues. It grabs up a lot of pet hair too, just as described. I've attached a video of some excess debris in the middle of a cage-clean today to show how well it goes! It also picks up and filters an insane amount of dust! Looking at my previous vacs, you wouldn't know how much dust was lingering about in carpets, on upholstery, curtains, etc. This Shark gives my air purifier a run for its money as far as dander and dust-filtering goes. The little air pod it came with leaves the air post-vacuum with a nice, fresh sent as well. The folding part of the tube makes for both easy storage, and a cinch for getting under anything that has a 90° angle, which is perfect for someone who has a back condition like me - no more bending and hunching and getting down on the floor! The main head also has a very versatile axis that makes it easy to manoeuvre and get into places that used to be fiddly or troublesome. I have extremely long hair that passes my bum and I swear I shed more than my long-haired, double-coated Pomeranian cross, but I have had zero issues with tangling in the vacuum head, which has been a blessing compared to my previous vacs, which have needed hair build-up to be chopped off the roll every few weeks. Quite literally, the only con I can think of is the tank size. However, that's no problem to me as my house is small and I have multiple bins about, so I don't mind emptying it as I go. The one-button empty mechanism is a blessing and I'm glad I no longer have to fiddle with the tank. All in all: amazing vacuum! Does everything it claims and exceeded my expectations. This is my first Shark and given many Dyson quality problems in the past, I don't think I'll be going back. Good job, you've converted me.

Very happy with my purchase. I would put this on par with a dyson vacuum, but alot cheaper with same good quality

This review covers the initial week of ownership; I will provide a long-term update after a few months of daily use, if I find any negatives. Our house is an average four-bed property, approximately 80% of which is fitted with new, deep-pile carpet. We required a decent cordless unit capable of serving as the primary cleaner. I opted for this Shark model over the Dyson V11 (nearly a hundred quid more) which I was going to buy, during a pre-Black Friday sale, and the initial performance regarding build quality, suction, and battery endurance has been excellent. The battery life significantly exceeds my expectations and contradicts negative online reviews. You don't need to go for the dual battery one unless you have a particularly big house. We are consistently able to clean the entire house—including all carpets, hard floors, and using the duster attachment for all shelves and flat surfaces—and still retain approximately 20% charge remaining. This capacity comfortably ensures a complete, deep-cleaning cycle of the property on a single charge. The cleaning power is comparable to our previous, reliable unit: a 5-year-old corded Shark Lift-Away. This cordless replacement matches the corded model’s deep-cleaning capability but provides superior convenience, portability, and storage. Furthermore, the IQ Sense feature is highly effective and responsive. It seamlessly and automatically ramps up the suction the instant it detects a concentration of dirt or debris, eliminating the need to manually adjust power modes. The vacuum has effortlessly replaced both our old corded unit and the secondary cheap stick vac previously used for quick cleans. While this is a significant investment, its proven ability to handle deep-pile carpet and function as a main, whole-house cleaner genuinely justifies the cost. Based on performance, I would consider it excellent value and would not hesitate to pay the full £450 RRP. It is a high-performance piece of kit.
