Compact, great suction, but noisy.
So far so good, though I will update if required.The good bits:Brilliant suction. Nice and compact if you have a smaller home. Nice and lightweight to manoeuvre. Performs very well on hard floors. Self emptying dust receptacle is great, especially if you don’t want to handle dead spiders! Bright headlights for darker areas. Great for animal hair.Not so good bits:The self emptying dock doesn’t always discharge everything, sometimes it needs a little shake. Not quite as good on carpeted areas, but still performs better than most. Charging lead isn’t that long. Run time not quite as long as it states, but still adequate.Emptying dock is noisy, not so good if you’re in a flat or terraced. Even though we’re detached, our neighbour claims to have heard it when we used it late one evening.Overall, bought this to replace a cordless Miele, and it (so far) has performed very well. Having recently moved to a larger house, it’s perfect for moving from room to room without the faff of plugging and unplugging. Not all of our rooms are used regularly, so just need a light going over most days.Husband has been doing some major building renovations, for which we’re using the Henry, but this is just perfect for everyday mess from the kids.Recommended if you can get it at the sale price.

Throw away your Dyson and buy this instead. Better for the planet and your back!
Superb addition to the Shark family of vacuums. Very lightweight; ideal for stairs with the pet attachment. Has suction equivalent to a standard Shark cordless but is far more nimble. The slightly smaller width brush head means you can access hard to reach areas, under sofas etc with ease. The vacuum in upright use weighs only 2.7kg kg, less with the attachments. It glides with smooth efficiency, with an easy swivelling head which means you can pivot with less wrist strain. It auto detects whether you are on hard floors or carpet, providing extra suction power for carpets. You can boost this further but I haven't found the need to yet even with pets. When clipped back onto the base unit.... that's when the real magic happens....dust and debris is sucked into the storage chamber on the base. This means that the unit is lighter, always clean, and thus at top efficiency. It has two attachments (a pet brush style one and a nozzle). You empty the caddy in the base unit (it just clips off) about once a month. The small caddy opens at the bottom so you can just drop the debris straight down into the bin without it flying everywhere. There is nothing NOT to like about this development in Shark technology. Same suction, same anti hair wrap, easier to use because lighter. I've had Shark vacuums for years and I honestly thought they couldn't improve on what they offered. For anyone looking for a speedy, lightweight, efficient vacuum (perhaps if you have health or disability) you absolutely want to consider this. Unlike Dyson products, Shark offer a no quibble 5 year guarantee (replacement parts until it works or a new machine). Given that we are all trying to make products last longer and keep them out of landfill, Shark is the far more environmental buy. I first discovered this model in a holiday home. Came home and immediately bought one. Life is too short to not get pleasure out of vacuuming (even if you hate the job). Love, love, LOVE it!!!!

Shark moves
It’s exceedingly heavy. Even with just the body and small roller or other attachment on its heavy. I like the easy to use set me back and I clean myself as well as charge myself docking station which is so easy to empty. Just hold over a bin or bag push slid the release button and yeee no dust covered me or floor’s etc. so that’s fabulous. The main head is easy to use and it is electric mind so no need to push like a cylinder vacuum. The anti hair thing is great noooo tangling awesome. That means I don’t have to clean the rollers of hair Great. The lights are cute. But me thinks it’s more you you can see the dust or what have you rather than it sensing it. The snap me in half stick is good so thanks for that. Great for underneath the beds low cupboards chairs However. The only carpet I have in the house are on the stars and landing. I think it could do better I like to see where the head has been you know the “ I’ve just been vacuumed look “ nope you don’t get it. I feel it could do carpets better Also right up to the edge nope perhaps I’m doing it wrong. But I thought it had the ability to vacuum on the sides You know when you vacuum along the skirting board I’m not happy or maybe I’m fussy. I vacuum every day. Downstairs tiled floors. And my bedroom twice a day. Morning and evening. No im not messy. But my hair is. And the lights on the head of modern cleaners mean You See Everything. Ugg. Oh happy me Bottom line is. Would I buy it again No. I’ve had better lol Could an old disabled person use it. ? I don’t think so. It’s too heavy. Does it clean well Hard floors yes. Rugs and short pile carpet yes. Around skirting yes but no. Is it easy to use. Yes It’s not the best I’ve owned it’s not the worst. The cordless thing is awesome no need to stop start plug in plug out so that brilliant.I leave it to you. Quality is good. Battery life is good 👍. Hair removal good it seems durable it’s not flimsy. I’ve only given 4 stars because it’s so heavy and I’m used to slugging 25kilo sacks of feed up and over my shoulders

The best vacuum I have ever used!
This is the best vacuum I have ever used. I used it today for the first time, and I was blown away with the performance. Love the dirt detection, and cleaning under furniture is a breeze now. Switching from upright to handheld is a breeze. It is a bit noisy, but I can live with that. Of all the vacuums I've owned over the years, this vacuum is by far the best... I love it.

Amazing!
OMG! This is amazing! The strength of the suction is very impressive, it toggles automatically between different settings and is really easy to put together and charge up. The battery comes out so you don’t need to plug the whole thing in to recharge. Very impressed!
