This vacuum is great, the suction is great but on certain surfaces the suction is so strong it gets stuck and doesn't move. It does turn upright if it's knocked over but this isn't really an important feature, if it didn't have this feature it wouldnt matter to me. It does pick up so much dust that you don't see and is great on our hard floors. The only issue is the suction which is also the best part. Very torn.

We purchase the blue one due to my partner having severe asthma. From the first time I used it my house never felt more clean! My partner went from using his asthma meds once a day to once a week and now it's once a month!! We have both carpet & tiles and it works amazing on both.
We love our Dyson!
The only downside is the noise (I've had Miele previously) and the short power cord.

I recently purchased a Dyson Big Ball Allergy vacuum, after my previous Dyson, DC 08, purchased in 2002, died. Having loved my Dyson, with it's amazing powerhead, the decision to select another Dyson was an easy one. How wrong was I. This model with its turbo jet sounding motor, is totally useless in being able to suck up dog hair from wooden floorboards. The powerful head, actually blows the dog hair around the room and leaves me totally frustrated at how I am going to get the floors clean. I have reverted to using a broom and dust pan. If you have developed a top notch product, why not just stick with it?

The suction is unbelievable. We live in an area where our doors and windows are open through most of the year. This creates a lot of dust in the house. The Dyson gets it all and the floors feel wonderful. Its not heavy and is easy to get around in tight spaces. We have a combination of wooden, tiled, lino and carpet in a 2 story building.

I recently bought a new allergy ball vacuum and I wish I hadn't spent all this money on something that has no suction. I need to go over the same spot numerous times to pick up a piece of fluff. The vacuum has not place to put the accessories like my old one and is made from cheap plastic.

It has great suction but within the first 3 months the head broke. Dyson happily helped my through it and sent me a replacement, but was very inconvenient as I had no vacuum for a few weeks.
For the price that it sells for, one would think that the hard floor attachment would be includuded, but it is not!

After research saw this has the best buy as I could get other pet accessories. i suffered last year badly from allergies as we have cats. The suction is great, its helped reduce dust and must be sucking up dust mites and cat hair as my allergies have been so much better now. The ball makes it easy to move around on the carpet and lino.

flexible, great suction, reduce the dust, not too noisy, efficient. Compare to others, you dnt need to put too much hard work in using this great Dyson. We have another brand of vacuum cleaner, which entirely can not compare to this Dyson brand. We just need to run it once through and save a lot of time.

Our previous DC23 was pretty awesome and had lasted us for many many years so when it blew up we automatically went out and purchased the new model in the allergy range thinking it would be the best. However, I was quite disappointed in this new model. The suction just doesn't compare to our older model and it feels like a light weight cheap version. Yes, it is so much easier to pull around the house while vacuuming but it lacks the powerful suction of our previous one. Our accessory tools still fit this new superseded model which is a bonus but if i had my choice over, I would continuing researching.

Everyone knows Dyson is an innovative company and their vacuum cleaners are constantly being updated with latest technology and designs. Ever piece of Dyson vacuum cleaner have been carefully thought through to give the best experience when using the product. There's quality workmanship throughout the whole product, inside and out.

It is a complete waste of time and energy, over engineered and doesn't do the job it is designed for, fiddly, hard to empty, too many places for things to get stuck.
I'm a designer, I know when something has been designed by committee with last minute dodgy fixes that don't work

Have the Dyson cinetic big ball allergy for 12 months.
Since the day I got it I've had no end of trouble emptying the barrel.
It either opens itself up as I try and first remove it from its base and it spills all its contents all over the place.
If I can lift it off successfully then yeh ha !!!!!
Sadly once I empty it into the trash bin the bloody thing won't close properly.
The clip that attaches the barrel back together is so small and a bit out of line so closing it becomes an issue.
Don't think the Dyson is all its cracked up to be.

This would have to be the most expensive and worst vacuum cleaner I have ever purchased. Cant even pick up a blade of grass off a tiled floor. Takes me 3 times as long to clean and then my mop still finds dirt. Moving from tile to carpet is horrendous as the vacuum head drops fluff and dirt on the carpet and then wont pick it up. I'm going back to my 15 year old Miele which still does a better job.
