Dyson DC33 Multi floor


Avg. consumer rating = 81/100 

This machine seems to have all the key vacuum cleaner features as well as very strong suction.  It is also not as expensive as some of the other Dyson uprights, however many consumers love this machine or hate it.  It does not get the very consistent high ratings of the Dyson DC25 Animal for example.   Owners are pleased with the powerful suction, long cord and large dirt canister however there are numerous comments regarding the less-than-stellar wand design and the noise generated when vacuuming on short carpet.

A review of consumer comments from many sites has provided the following common Dyson DC33 Multi Floor likes and dislikes:

- Very powerful
- Long power cord
- Large dirt canister that is easy to empty
- Durable
- Generally not too noisy
- Easy to maneuver
- Good on both carpet and hard surfaces
- Washable filters

- Not easy to get under low furniture
- Hard to push on deep pile carpet
- Extension wand handle is not strongly made
- Retractable hose is stiff
- Extension wand is awkward to use
- On low pile carpet or area rugs there is sometimes a grinding noise (mentioned by quite a few owners).  This is, apparently, the result of the brushbar clutch slipping due to too much suction.

The Dyson DC33 can be found at a number of online outlets and as a result there are many comments and owner ratings available for this particular machine.  The table below shows consumer ratings from several quality sites.

 Source  Consumer Ratings  #Ratings
 Amazon  3.7 stars out of 5  39
 Best Buy  3.7 stars out of 5  28
 Walmart  4.5 stars out of 5  15
 Kohls  4.3 stars out of 5  20
 Lowes  3.9 stars out of 5  7
 Bed Bath & Beyond  4 stars out of 5  7
 Macy's  5 stars out of 5  12
 Sears  4.5 stars out of 5  8

Ratings are a little inconsistent with some websites giving the DC33 high grades and others finding it somewhat lacking.

The Dyson DC33 Multi Floor upright vacuum cleaner is, according to Dyson, designed for use on many floor types including carpet, ceramic, vinyl and wood.  Dyson doesn't really make it clear what is supposed to make this vacuum better than other Dyson machines on these floor types, but it is likely the automatic height adjustment that is supposed to ensure optimum cleaning distance between the nozzle and the floor. 

The DC33 also comes with a motorized brushbar with an on/off switch in the form of a pedal at the bottom of the machine.  This switch allows the user to transition easily between carpets and bare floors.  The brushbar can be engaged to ensure proper rug or carpet cleaning and disengaged so the unit just uses suction on bare floors or delicate surfaces.

It is powered by a 12 amp motor and uses, like all Dyson vacuums, root cyclone technology.  This technology spins air very rapidly and forces debris out of the air flow and into the dirt canister – an approach that ensures no loss of suction over time and also helps to keep filters cleaner longer.  The DC33 has 240 air watts of suction (by comparison the DC28 has 235 while the DC25 has 220). 

Dyson uprights all come with HEPA filtration.  This is a high level of filtration that removes 99.97% of all particles with a diameter or 0.3 microns or more.  This typically includes dust mites, pet dander, pollen, etc.  The DC33 appears to be certified asthma & allergy friendly by the Asthma Society of Canada but so far is not certified by the Asthma and Allergy Foundation of America (according to Dyson the uprights with this certification include the DC14, DC17, DC22, DC23 Turbinehead, DC24, DC25 and DC28).   The HEPA filter can also be washed and reused so there is no need to buy expensive HEPA filters time after time.

The dirt canister on this vacuum is quite large with a capacity of 0.61 gallons (2.3 litres).  One of the few shortcomings of the DC25 is the small dirt canister which is only 0.31 gallons.   The DC28 also has a 0.61 gallon dirt canister.  The dirt canister is easily emptied via a push button so there is limited contact with dirt/dust when emptying (consumers do comment on how easy this canister is to empty).   The canister is made of clear polycarbonate which allows the user to see the amount of dirt and therefore know when emptying is needed.

According to Dyson the DC33 telescopic wand has been re-engineered and is now lighter and also provides 4 inches more reach than other models (yielding a full 15.7 feet of reach).  However the wand is one of the main areas of consumer contention with this vacuum.  Comments include the likes of:

- the wand has a flimsy handle
- the stiff hose makes using the wand frustrating (tends to pull vacuum over)
- you have to unravel the entire length of the power cord to use the wand

The hose length is a full 15 feet but it is considered a bit stiff and not easy to stretch out or flex.  This contributes to the difficulty in using the wand.  In addition, this vacuum doesn’t clean right up to edges (leaves about an inch or so along the baseboard un-vacuumed) so it is necessary to use attachments like the wand for this, further frustrating some owners.

The Multi-Floor weighs 17.6 lbs which is perhaps slightly heavier than most uprights but is about average for a Dyson.  The vacuum is marketed as lightweight and compared to the DC28, for example, it is.  The DC28 weighs 20.6 lbs.  However the DC25 only weighs 16.1 lbs. 

This is a fixed wheel vacuum and not a Dyson Ball machine.  But consumers generally feel that it is quite maneuverable.  Although there are some comments indicating that it can be an effort to push on area rugs or deep pile carpet.
The power cord on this unit is quite long at 35 feet.  This is a great feature and one appreciated by many owners.  A vacuum with a short power cord can be quite frustrating. The DC33 also comes with a stair tool and a combination accessory tool (which is both a crevice tool and a brush).  The tools store on board the vacuum.  Like all full size Dyson vacuums the DC33 carries a 5-year parts and labor warranty.

OK I found a very solid fix that works perfectly (at least in my case). The issue was that the walls of the belt channel were rubbing against the brush, which was causing constant friction. Add the additional friction of the brush over carpet and it triggered the clutch, causing that awful noise.
Those walls to NOT need to butt up against the brush like that (the brush is supported completely by the and caps / bearings on either side.
So when I removed the brush, I saw that the plastic around the belt channel was all burred and chewed up. I simply took an exacto knife and very easily carved it down, taking a good bit of material away (it's very soft plastic and cuts very easily) until the brush had lots of clearance. You'll notice a huge difference when you put the brush back in place. My wife is now currently vacuuming the entire house with a huge smile on her face and I'm not on edge with anxiety that I'm about to get a brain shock from that god awful noise.
so in short:
1. remove the cover with a coin
2. remove the brush by using a screwdriver to slip off the belt.
3. making sure to keep the belt out of the way, carve down the walls of the belt channel
4. place the brush back into position to make sure it's completely clear of the belt channel walls and test that it moves freely.
5. replace the belt, making sure you don't add any twists
6. replace the cover
7. vacuum happily knowing it's not going to yell at you.
hope this helps!

I just called Dyson's "help line" about my new DC33. It is a total piece of s#!%. I am over 60 years old and have had many upright vacuums over the years, and their answer from the "help desk" was total BS. I was told that uprights tend to be so powerful that they get stuck in heavy carpet, and that I should be using a canister! Somehow, for the past 50 years I have been successfully using other uprights and did not know I needed a canister. I have had the same problem as everyone else from the very beginning. The beater bar gets stuck and makes a terrible noise when going from one carpet type to another, or sometimes just for no reason. Today I got new carpet in a bedroom. I tried to vacuum up the loose threads. The vacuum did a "faceplant" and could not move at all over the new carpet. The new carpet is not extra long or thick, the vacuum just got stuck and absolutely would not push. This is a very poorly engineered machine, and it is irritating that Dyson will not take any responsibility for it. In the very least they could have suggested doing what Tommie Thomas suggested; removing a seal to lower the suction. I had a DC14 for many years that I loved, but this experience and Dyson's poor customer service has left me furious. I will never buy another Dyson product again. They are over-priced and they do not back their own products.

Same as many above. Right out of the box, before and hair or anything else could get caught up in the brushes it makes a loud grinding noise only when you pull the handle down to start to vacuum. Doesn’t seem to matter which kind of carpet I’m trying to vacuum although it’s louder on deep pile. Sent in to Dyson and returned saying there’s nothing wrong with it. Fired it up and same thing. The operator on the phone from Dyson can hear the sound. Sending it back in tomorrow but this is ridiculous. It’s obviously an issue many people are dealing with and for a vacuum this pricey, we shouldn’t have to go through this right out of the box.

I bought this as xmas present for wife in 2014..It made the grinding noise out of the box when you put your foot on the head and pull down the handle to vacuum..It didnt pick up anything on our bare floors or downstairs carpets.. It was relegated to bedroom only bc we have a carpet that it seemed to work on...Every time I use it and it makes this grinding noise I want to throw it out the window. I removed the gasket and it still makes the noise. Now it sometimes picks up dirt and sometimes doesn't.. I use a hoover to clean up after it. HUGE PIECE OF OVERPRICED GARBAGE. WILL NEVER BUY ANOTHER DYSON AGAIN!

Removing the rubber seal gasket is not a solution, despite everything that is said. The reason why the beater bar or brush roller is bound up is because hair gets caught in the end of the spindle. In order to remove this hair that is now fused to the point where it's burnt in, you need to lift the roller up over the belt-side edge, take the end cap off of the belt side, slide the thin metal rod out from the other side by pulling the other end cap and scrape all the hair out of the cavity at the end of the spindle. Using a wire brush in there helps tremendously. When it's all cleaned out and put back together, you will notice a huge difference in how free the brushes spin. When that's cleaned out there will be no more noise until it builds up again.

The above post ^^^ is correct! Take out the brush bar as described and pull one end cap off. I cleaned a ton of my wife\'s hair out that had clogged each end(she has long beautiful hair btw:). Be careful because there are some ball bearings that might get loose. I put the brush bar back together and re-installed in the vacuum and BOOM BABY! Works like a charm! Now she\'s happy so I\'m happy:)

and it is only when the handle is down to vacuum it is because the brushroll is not turning when the machine is set to carpet. Remove the soleplate (bottom piece) by turning the 3 screws underneath and gently pulling it off. Now for the tricky part. Getting the brushroll out of the machine. You *can* buy a tool for it and I suggest you do. Like this: http://www.amazon.com/Vacuum-Fix-Dyson-Belt-Change/dp/B004IHD8FU If you don\'t have one or can\'t wait then you can kind of twist/spin the brush in one direction and pull it away/out from under the belt from the belt side to the non-belt side. After the brush is out try to hold just the ends and spin it with your fingers. If it does not spin freely, then pull hard on the end caps. They will probably come off, but not necessarily. If they do clean all the hair, etc from the end caps and the brush. If they don\'t come off, just clean it the best you can. VERY IMPORTANT: Look to see if there is melting anywhere on either brush end or end cap. If so, buy a new brush and put it in. Using a brush with melted ends will likely only damage your vacuum. If not, put the brush back together, spin it with your fingers and see that it spins better. I like to loop a piece of quite small rope through the belt and use it to pull the belt out far enough to get the brushroll under it if I don\'t have the tool handy. Put the brush back in, replace the soleplate and start it up. All should be well.

PS The DC07, DC14, and DC33 are all essentially the same vac with different colors and release dates...

Ok guys so who\'s gonna open up their 33 and find the issue. I have the same problem as Linda and the other jay. I didn\'t go to remove the rubber. I\'ve did lots of cleaning and washing filters and such, but I didn\'t want to remove anything yet. I narrowed down the noise to inside the case of course. Yes mine only make that sound when angled on carpet setting. Any takers on opening it up?

So I took the rubber strip off and tried the vacuum my area rug. I was so happy cause the noise wasn\'t there, that only lasted about three minutes and the noise returned. What do I do now?

We have a dc33 at my work. Got a string of carpet caught in it. It started making a horrible noise. Not when standing upright, only when handle is put down. I tried taking out the rubber seals. It didn\'t help and I can\'t find any cracks anywhere. Any other suggestions anyone?

Thank you so much tommie thomas!!!! I can\'t believe, just removed rubber seals from both pieces and it has no more grinding rattle sound!!!! By the way it is much easier to vacuum now, I don\'t have to push hardly as before, it\'s going freely now and there is no noticeable loosing of suction. just working as it should. Thanks for help!

I took off the plastic bottom piece, removed the brush and cleaned off all the hair and string, then found the thin rubber seal running along the bottom of the vacuum cleaner in a small groove. I thought \"how is taking this out going to help\", it seemed so insignificant. It totally worked! No more loud grinding noise from our DC33! Thanks for the fix!

Have a dyson DC33. Got the rattling on third use, noise didn\'t seem to be what others were describing. Turns out the short side of the brush had cracked around the pivot. Dyson thought it was damaged by dropping. Afraid not. All I can think is that the motel carpet I vaccumed is a plaid pattern, with ridges in the plaid pattern, the carpet is very hard, and I think it was like running the vaccum over a power cord. Or maybe it was cracked when I bought it and it completed breaking. Ordered 3 more brushes. Even without the brush, it cleans really well. If these brushes break, I\'ll return it and get an animal

We have always experienced the horrible grinding sounds when vacuuming our rooms with low-pile berber carpets. however, now it is constant and does it on all the carpets!! Horrible sound!!

after removing the bar and cleaning the hair off, we examined and found that it had cracked at the edge on the shorter end of the brush. Owned only 5 months!

Only 45 days old, started with the horrible noise. Called Dyson finally since packaging states not to return to retailer, contact Dyson. Thats what I did. Let her hear the noise and she asked if I was doing area rugs, well yes I am, a 9x11, a 5x7 and a runner. Her response \"well, you know the dyson is very powerful and will always make that noise because of the suction and the brush will quit turning but the belt continues to run\" and she proceeded to let me know her opinion \"The Dyson DC33 is not made for area rugs and I should have gone with a different brand\" I guess she is tired of hearing the same complaint also. What a waste of $350, never again. Last Dyson made it 7 years....this one 45 days. Thats one expensive mistake.

I recently bought the Dyson DC-33 multi-floor vacuum. I love it but do experience that \"grinding\" sound when using it on the rugs (low pile). It sounds horrible. The first reveiw told how they fixed that proble on the DC-14. Is that a good fix for the 33. Thanks.

The suction is outstanding, it does a great job cleaning floors (both carpet and bare floor). But the wand is quite annoying to use and does tend to pull the vacuum. That part is not particularly well designed. Overall, I think it\'s a fairly well made vacuum with some definite points for improvement.

I read a lot of reviews on this vacuum and there were several points never made. It does have a lot of suction but so does my $69 Dirt Devil. It is clumsey, the wand is stiff and does not reach to the top of 12 steps. There is a lip around the canister where dirt collects and I have a hard time getting the dirt out. The top of the vacuum is higher than most and things I use to be able to sweep under, I now have to move. The attachments are pretty poor and the wand is a different size of my last vacuum so I can\'t use my old attachments. And the final and worse thing is that after about 3 or 4 uses, the upright part of the vacuum stoped sucking dirt up. Luckly the nice people at HH Gregg will take this broken vacuum back. I don\'t think I\'m going to try another dyson, I\'m not really sure they actually use these vacuums to clean their floors.

The extension cord is very awkward to use, it bends all the time, in addition it looks very flimsy and i get a feeling that it\'s going to break any time soon. Vacuum is very loud and heavy. I wish I never spend so much money on this particular brand.

The cord isn\'t high quality but it\'s not going to break, and the noise level is much better than the dirt devil I have.
This is an excellent vacuum, with the exception of the grinding noise on area rugs.

just fixed my Dyson DC-14. It would make a loud grinding sound but only when I vacuumed the area rug (low pile). I did some googling (thats a word now) and found that the suction is TOO GOOD and low pile binds the beater bar. All i had to do was remove a very thin rubber seal from the beater bar housing, and it was fantastic with no noticeable loss of suction. Just undo the 3 large flathead plastic screws, remove that plastic frame, flip it over and near the back where those screws were at, u will see a thin strip of black rubber. Peel it out and your problem is solved.

I vacuumed my area rug just yesterday and was incredibly frustrated with how often my Dyson would make that horrible grinding noise. At least 10 times on my small 6x8 rug. Removed the little rubber strip and tries it again and it didn\'t make the noise once. This is fantastic. Thanks for posting this fix.
