Question: how many attachments were available. I appear to be missing brush attachment?
Document: This vacuum was surprisingly good. It was very easy to assemble, the instructions were clear and everything popped together without tools.It has great suction. I was very surprised at how much dust and dirt came up on the first cleaning. We emptied the dust bin twice! The suction is just as powerful with the attachments.The attachments are easy to connect and the power is very strong. The extension rod was great for top shelves. The corner attachment is not very handy.
It does a decent job on bare floors but I swear my 15 year-old WindTunnel has more suction power. Anyway I never used the cleaning wand but now it's not working. This means I cannot use any of the attachments if I want to vacuum my stairs, walls, corners, etc. I called Electrolux and after doing some troubleshooting over the phone, I was still unable to get the suction to work with the hose attachment.
I would recomend Electrolux replace the small plastic hard surface wheels with rubber wheels, to cut down on hard surface travel noise, add a retractable cord reel and a longer hose.Since we had a good warranty experience with Electrolux I purchased our second one model EL8807a for our upstairs. It is too new to review, but performs very well so far. Has many similiar features as the EL8502. I hope the roller brush cleaner continues to work as advertised since this was one of the reasons we purchased it.
I feel like an actual replacement will have to be ordered for that part.Finally, the collapsing/folding brush head attachment tends to fold back shut on its own force too easily making it hard to do what you intend for it. Somewhat good for flat surfaces and angled edges (think edges of stairway steps) and small places, but pretty small as a floor sweeper.
This is my third Electrolux. The other two were tanks and cost many hundreds of dollars more than this one. They lasted a decade each (one still in use at my church).. I'm thinking I'll be lucky if this one lasts one year. But so far it's an improvement over my old Oreck vacuum (which needed new brush every few weeks and swallowed carpeting whole). If it lasts 5 years, it will have been worth it. GOOD LUCK!
If you've ever had a problem with long hair tangling up in the vac's beater bar and subsequently burning through the vac belt, this vac is for you! The brush roll cleaner is very effective and such a great innovation. We've gone through at least four vacuums in about as many years but this one has lasted for over six months without any problem whatsoever. It is a bit heavier than other uprights we've had but it isn't unreasonably so. It is very easy to remove the canister for emptying.
Good features. I like the way the wand works it's straightforward and simple to operate. The brush cleaner feature is really innovative on a unit at this price range. Mine only came with two attachments though4. It's not loud. I love a powerful vacuum but they are often extremely loud and I have no desire to go deaf from vacuuming. This is probably the quietest upright vacuum I've used.5.
If it flipped in the opposite direction and cleaned the area between the floor and the baseboards, that would be great! That would also make it easier to clean the inside corner of the stairway, which is much harder to reach than the outside edge of the stair. It's basically a useless attachment.I used the brush roll cleaner, although at this point there wasn't a lot to clean. I saw a few hairs that disappeared - although it comes at a price - it sounds like an ice cube grinder!
Very good cleaning, adust container is big enough to do several rooms before emptying. I also used the wand feature with the "multi-tool" which I did not find that effective. I prefer the regular dust brush attachment on the wand and used it to clean spider webs and to dust window sills etc. That works very well. One design highlight is that the vacuum body does not tip over even when the wand hose is stretched to its maximum of about 12 feet.
I purchased an Eectrolux with Brush Roll Technology (almost same model as the one on these reviews) from Sears. Very attractive and modern looking machine but don't be deceived. Have had it for a year and a half. After about a year, attachments lost suction and finally the whole vacuum lost suction. Still runs but does NOTHING! I contacted Electrolux via their email to complain and tell them I have purchased a Shark Rotator Lift Away but have received no response from them. I love the Shark!
Answer: There is  a small brush attachment and something that looks like a clamp. I'm not sure what the clamp thing is for.
