Q:Who invented the earliest vacuum cleaners?: 1907 Ohio inventor Shiban Guerra made cleaner light, he was the administrator in a shop, in order to reduce the burden of the carpet, a vacuum cleaner is made, with fans will create a vacuum dust inhalation machine, and then into the pocket

Q:So I went on a trip, and I put my clothes in SpaceBags to save space. Problem is, there's no vacuum in the hotel for when I'm repacking to go home. I only brought one bag, and there's a one-bag limit. No carry ons. What do I do about it?: Hotels have vacuum cleaners. Ask the maid if their hotel has vacuums with a hose and if you can use it briefly.

Q:What's wrong with it.I changed the bag and dug everything out of the bottom, got a bunch of stuff out but it still isn't working?: Sounds like your vacuum is clogged remove the hose and see if you have air flowing

Q:preferably dyson brand but it doesnt really matter: Just about everything goes on sale. Dont buy Dyson! I hate mine. I wish I never spent $400 on it! I have a Siberian Husky and it takes me two tries at vacuuming a room just to get everything up. It really is the biggest waste of money I have spent on anything. Ya, they look cool, and have good marketing, but its crap! at least for me it is.

Q:if you brought a battery operated conventional vacuum cleaner into space, in theory would it work? would it be able to create the internal vacuum to make it work? ( I am thinking along the lines of positive and negative pressure): no, you need matter to make a vacuum and space has no gas or pressure for this to happen. nothing would be moving. you need gas to produce the suction which produce the vacuum

Q:Our vacuum cleaner brush roller is not working. My husband has already tried to fix it himself, but he can't find out what's wrong. We've already replaced the belts and the brush roller doesn't seem to be worn down or missing any pieces. Does anyone have any idea how much it might cost to get it fixed if I take it into a vacuum repair shop? The vacuum is only a year old and everything else works fine, the roller just isn't rolling.: This may sound silly, but it happened to me. Our vacuum brush roller stopped working, too. Turned out that the sliding switch that gave the bare floor/carpet option wasn't fully engaged. If you have a switch like that, check it. Also, if you still have the manual for it you may want to check under the troubleshooting section or look on their website. At any rate, I take my vacuum cleaners to Sears for repairs. It usually runs me $60.00 - $80.00, depending on the problem. You may want to shop around. Ask people in your area who they go to. Sears is more expensive, but they're reputable and stand behind their work. Hope this helps!

Q:what brand do you recommend? I have 900 sq ft of carpet. I might replace the carpet with tiles. how long can a small vacuum like that work without engine getting too hot and shut down?is it expensive to maintaing?: No, but I do know how to spell INCENSE. Unlike you.

Q:Please recommend a good & cheap vacuum for carpets and rugs.?: hey there- if you're cleaning carpeted stairs a gr8 idea is to use a rubber brush then a high quality dustbuster. there is one sold named xtreme power and it's awesome i have one

Q:I want a vacuum cleaner that will pickup pet and human hair and not clog up. Which one of these would be the best?: I have tried many vacuum cleaners over the years even Rainbow and I keep coming back to the cheapest Bissell from wal-mart. It does a great job on pet hair and for $40 you can replace it ever couple years if you need to and still feel like you have gotten you moneys worth. I have 8 dogs and I have had the last one for 4 years now and its still going strong. Good luck.

Q:Vacuum CleanerWeights Upright vacuumcleaners have either a hard body type or a soft bodytype. Shown are the weights in pounds of a sample ofeach type. At a=0.05, can the claim that there is adifference in the variances of the weights of the twotypes be substantiated?Hard body 21 17 17 20 16 17 15 20 23 16 17 1713 15 16 1818Soft bodied types24,13,11,13,12,15: Hard body : Arithmetic mean : Xbar = ΣX / N = 296 / 17 = 17.4 Standard deviation : s = √ [Σ(X - Xbar)^2 / N] = √ [96.12 / 17] = 2.38 Variance : s^2 = 5.66 Degrees of freedom = 17 - 1 = 16 -------------------- Soft body : Xbar = 88 / 6 = 14.7 s = √ [113.34 / 6] = 4.35 s^2 = 18.92 Degrees of freedom = 6 - 1 = 5 -------------------- Using the F distribution : F = (larger variance) / (smaller variance) = 18.92 / 5.66 = 3.34 (with v1 = 5 and v2 = 16) This is a two-tailed test because the null hypothesis is that there is no difference between the variances. With a 5% probability limit, each tail area = 0.025. Looking up a table of the F distribution for v1 = 5 and v2 = 16, the value given for 0.025 is 3.50. The observed value of 3.34 is less than 3.50, so it lies between the 5% probability limits. Thus, the null hypothesis is accepted, so the claim that there is a difference in the variances of the weights of the two types CANNOT be substantiated, at the 0.05 level of confidence. (My apologies to statistical experts if that is incorrect)
