Vacuum Cleaners Discussions

I live with my parents in a luxury 2-bedroom apartment (1184 square feet).  The floor is mostly carpet, but the entry and kitchen have what I think is ceramic tile, with recessed grout, and the bathrooms and laundry room have what I think is linoleum style to look like tiles.

A couple of weeks ago, my mother's caregiver said the vacuum cleaner (a Nilfisk GS 90 that I think we bought in 1992 if not earlier) had stopped working.  I took it to a repair shop, and I was told that it was some voltage controls that had overheated because the bag was full (I don't know when it had last been changed, and the caregivers might not have known how to open it to check the bag; also, even before we started having caregivers come, I rarely thought to check the bag before using it).  He was having some trouble finding prices for them, but considering its age and that it was already overdue for more than $400 of replacement parts (the hose, the hepa exhaust filter, the micro filter, and the main filter), I figured it would make more sense to buy a new vacuum cleaner.

However, I'm having some trouble finding one that's a good compromise between the features I want and the cost.
Given that the failure was apparently caused by an overfilled bag, I figure I should get one that makes it easy to know when to empty the bag/bin, e.g. by having an indicator light turn on.
I'm fairly sure I want a canister vacuum rather than an upright (among other things, the space we used to store the Nilfisk in wouldn't fit an upright)
I want it to be reliable, and fewer/cheaper expected replacement parts would be good (e.g. bagless, washable filter).
A HEPA filter would be nice, since my father and I both have allergies, but probably not critical, since we'd continued using the Nilfisk even though it has been a little over 8 years (iirc) since last time the hepa filter was changed, so it probably had reduced effectiveness.

Can anybody suggest a vacuum cleaner that would be good for my family?  Preferably under $300.

$400 for a hose and three filters? You need to find a better vacuum shop. That shop owner just wants to take your money. The hose ought to cost thirty to forty five bucks depending on where you buy it. The highest price I saw was under $100. The exhaust filter pack is under $40. The on/off switch, if that is what failed, is under $50. I can't find a circuit card as such to price it but those for other vacuums seldom top $150. Shop around. This vacuum shop is trying to clean your wallet. If you want a good quality canister vacuum that will last 20 years assuming you replace the premotor filter every five or six bags and always use cloth HEPA bags, try looking at Panasonic canister vacuums. The MC-CG902 is identical to an old 1990s Kenmore Progressive canister with the exception of having a much better motor. Four full sized attachments, steel button lock wands, the industry standard powered floor brush (parts everywhere, been in production in one form or another since about 1980) and a very simple circuit. No printed circuit boards, only a simple universal relay and everything else hard wired. If you want more features like adjustable motor speed look at the MC-CG937. The MC-CG 902 can be had for around $225 or even less if you shop (try Home Depots on line store). The MC-CG937 will set you back $350-$375. Either vacuum is well made and very durable. With the money you save you can go out and buy a really nice rubber wheeled horse hair hard floor brush and a telescopic wand for the tiles portions of your place. Both come with a hard floor brush that is ok, but a good wheeled one like I described is sold for under $20 (central vacuum systems use them so they are abundant and cheap). Simple non powered wands are likewise $25-$30 affairs. Keep the brush on that wand and you have the same tool Miele includes with their overpriced vacuums.

The $400 was not from the shop.  I called the manufacturer in December 2012 to get the part numbers and possibly prices.  I don't remember whether these are prices they gave me or prices I found, but here's the breakdown:
main filter (part number 61588200) $72.69
micro filter (part number 11730410) $36.92
hepa exhaust filter (part number 01727631) $225.97
vacuum hose (plastic) (part number 12041500) $76.01

Total $411.59

Your suggestion, the Panasonic MC-CG902, looks like a strong possibility, though I'm not finding any indication that it makes it easy to know when to change the bag and/or filters (since I won't always know how much the caregivers have used it).

Those prices are an outrage. The C-Vac replacement filter for Nilfisk P/N 01727631 lists for $72.95 and is a US made part. Even still I can buy complete new replacement cloth outer bags for a Kirby for less ($60-ish) or three HEPA bags for about $12. I suggest shopping around for those parts, but for the price you were quoted for just one new filter from Nilfisk you can buy a whole new vacuum from Panasonic. Filters for those are not costly (Kenmore CF-1 and EF-2 for the MC-CG902), nor are very good cloth HEPA bags (Kenmore Q bags, $20.95 for a package of six bags at Sears). Something to think about. Kirbys cost waaaayyy too much new, unless you are one heck of a negotiator, but at least normal wear items are priced humanely. Nilfisk is going to alienate a lot of customers charging those kinds of prices for filters that require frequent replacement.

Based on my understanding of HEPA (which admittedly is mostly from Wikipedia), I find it hard to believe that cloth bags could qualify as having HEPA filtration.  Could you explain that?

As far as the C-Vac replacement filter, I'd be willing to consider it if I wasn't already planning to replace the vacuum cleaner (though I'll wait another day or two to allow others to chime in with alternative suggestions), and I'm puzzled that only one store selling it shows up in Google Shopping when I search for the part number, while a total of 13 stores show up selling the Nilfisk-brand filter for $186-$404.

The "cloth" is synthetic material, basically blown glue, with very small pores. In general if the filter media filters 99.97% of particles down to 0.3 microns in size then the filter media qualifies for a HEPA designation. And that is what the bag is, a filter media that also happens to contain the dirt. You can see when you use HEPA bags the bag chamber of your vacuum stays very clean and the other filters do not become as dirty as fast. Here is an interesting primer: http://www.donaldson.com/en/aircraft/support/datalibrary/042665.pdf You can read my previous recommendation for a high quality vacuum that does not cost a huge amount of money, from Panasonic. Alternatively you can often buy store demos of high end Kenmore canister vacuums for very little money from freight liquidators such as Empire Liquidators. Many Sears stores will also have a department selling close outs. I have seen new in box Kenmores sell for around $115 on closeout, and these are not the Chinese made cheapies but the better Panasonic manufactured models from their big plant in Nuevo Leon Mexico.
