I'd just like to comment that I'm a Kirby saleslady, and I don't feel like I sucker people into anything. Whoever you purchased your Kirby from may not have been completely sold on the product, which could have made you feel that way. I'm completely sold on this item and feel like I'm helping save people on carpet replacement and paying someone to "steam clean" their carpets. (Which have you ever noticed after steam cleaning the same stains come back because they don't bother to pull out the condition underneath, and then it just works it's way back to the top? Plus, what happens when the padding gets soaked or crushed? It's kind of like purposely flooding your house.)
Before I worked at Kirby, I bought a Sentria for 2600 dollars and felt it was worth every penny. I never have to buy swiffers, brooms, mop and buckets, plastic vacuums, or any other dusting tools again. Not to mention lint rollers or compressed air again. Which I learned just redistributes the dust anyway and that's not what we're trying to do when we clean, right?
Anyway, if ya'll have a Sentria and it seems heavy, make sure your drive button is down. If you're doing carpet and it's in neutral, it will be heavier. Always put it in neutral to clean hard surface flooring since you don't have the friction if carpeting, otherwise the wheels can scuff your flooring.
To clean your stairs you don't always have to use the handheld portable. I would do that every 6 months or so for a real deep clean and use the Zipp brush for maintaining the stairs.
And if you're not cleaning your mattress, I really think you should if you have allergies. It's not the dust mites or the skin that could be irritating you, but the dust mite feces is what gets us. It has an enzyme in it that can trigger those reactions. With the filtration and the Hepa 2 bags, you can reduce the dust and dirt in your home by 85% if you vaccum every day for two weeks or every other day for a month.
It's great if ya'll like the Oreks and Dysons...I almost bought an Orek before I learned about Kirby. I've tested many Oreks, Dysons, Rainbows, Meiles, and even Filter Queens. and none of them have the cleaning capabilities of the Kirby. Believe it or not, a Bissell has more suction power than a Dyson. My plate tester fell right off the Dyson with the brushes going and the suction, whereas the Bissell was able to hold the plate on during the same test. However, the plate has to be slid off the Kirby from the side...it can't be pulled straight off the front like the rest.
As far as the tray on the shampooer, having it open like that causes less stench and bacteria. If it gets too full, I would just empty it when I got finished with half the room for a while until the amount of condition is less. I like to tell my customers to vacuum for a whole month with the upright before they shampoo because with less condition under the padding and at the base of the carpet, the shampoo comes out so much brighter. I would also use the shampoo to pretreat spots and then go over it with the shampooer, and work the solution in so the stains have a better chance of coming unbonded from the fabric. I would then wait until the carpet is dry again, and vacuum once more. This reduces the (very little) residue that would be left.
I hope you're still enjoying your Kirby, and I agree that it is a good investment. The Sentria has a minimum life expectancy of 40 years, plus you can always use the lifetime rebuilding agreement at any time as many times as you want. Your Sentria also has a fire relacement plan on it too. Btw, $1300.00 is a steal! My boss won't let us go below 2000 very often because we had them at $1888.00 for so long corporate called us and said we had to raise our prices. It really depends on the distributor. If you got it for $1300.00 you were sincerely lucky considering how much I paid for mine. However, if you hadn't bought it new, Kirby wouldn't honor those warranties on an old machine. I've learned that nothing good is cheap and nothing cheap is good. Plus, you really don't know what condition an older machine is in, what the people before were vacuuming up, ect. The Kirby is powerful enough to vacuum up things like staph infection, and old vacuums are like used toothbrushes. I personally wouldn't want to do that but to each his own. I do collect the antique Kirbys but would never use them to vacuum my home.
