Keeps ALL it's promises
Configuration: Vacuum
12/27/18 I have been using this vac over a year to clean our home's hardwood and vinyl floors and low pile area rugs. Disclaimer: we are not related to the company in any way, shape or form - have to say that because this review may sound like a commercial! This vacuum is small, quiet, very powerful and fulfills every promise the company makes about it. This unit comes with 3 small tools contained in the unit, 1 hard floor tool (vacuum powered) and 1 low pile carpet tool (vacuum powered). The 2 floor tools clip onto the sides of the canister. There are 6 power settings from a low for drapes to a high for hardwood floors, all marked with an icon. The power cord IS EXTRA LONG - yes, fewer plug changes - and the re-tractor works beautifully (I do let the cord slid through my fingers and catch the plug end to keep it from slamming into the back out of habit). The wand section is collapsible, which I just thought was nice for storage until I began using that feature while vacuuming in tight spaces, where you can change the wand length on the fly. The floor tools' articulated connection to the hose looks quirky until you begin using it; it makes the tool head extremely nimble in getting into tight spaces. The hard floor head has a skip tooth brush pattern around the edge which pulls in dust instead of pushing dust in front of it. The suction works all the way out to the ends - it will pull dust into the head from ALL the way around. The dust bag and separate HEPA filter have markers to let you know when to change them. I haven't changed either yet (note: we do not have pets, the house is vacuumed weekly). It tracks easily and the side bumper strips are placed where they actually work! Problems? well it is expensive, but I don't see replacing it any time soon. Seriously, I am still amazed at how well built and well thought out this unit is.

I absolutely hate this vacuum.
Configuration: Vacuum
I bought it due to the positive reviews and was tired of my Dyson ball vacuum. Since day one I have had nothing but problems with a vomit like smell that comes out of this vacuum every time we use it. It got to the point that we have replaced the filter with expensive carbon filters, washed out the hoses and attachments with bleach, and nothing has worked to get this thing to smell better. To make matters worse, the suction power of this thing is limited at best compared to other vacuums we have owned. I can go over the carpet with my old Dyson and pick up a significant amount of dirt that the miele cannot even come close to getting. I wish I had returned it when I still had a chance. We have now bought a iRobot Roomba 980 and honestly it is 100x better than the Miele piece of junk that just sits in the closet now. It has strong suction power, is easier to clean, and keeps the house clean.

Nearly perfect!!!
Configuration: Vacuum
My Dyson ball cracked & I needed to replace. I despised my Dyson; it pushed more around than it picked up. I've been researching vacuums & landed on Miele but it took me a while to land on what kind. I have mainly hardwood floors & wanted something good to dust, do stairs & be a good total hope vaccuum. I have allergies so C1 series out. C2 is too compact so I landed on C3 (great YouTube videos on all this). This is a lower C3 end with the bells & whistles. I can click controls with my foot & I forgot how nice retractable cord is. What drive me to this model is the turbo brush head... this head had great reviews. So I just got it & used & WOW. My floors feel so clean. The crevice & dusting attachments are great. I whipped through all my baseboard & trim in no time. It's light weight & doing stairs was easy compared to clumsy Dyson. The Jose is flexible & easy to work with. The only con I can see, & I saw reviews on it & agree, there should be a handle to hold the vacuum head with v holding the curve of the hose. It feels ergonomically off when doing floors but it feels fine when dusting/stairs. Other con is that the hose doesn't stand up line an upright (which I expected since it's a canister) but that's really it. The pros so far confirmed I made the right choice. I have a small dog but she doesn't shed. When selecting a model you need to think of what your needs are & what attachments come with each & go from there. Analise model has more features but I wanted an out of the box, w: right attachments ready to go. It's an investment so I feel like I made the right choice on this one.

Great way to control TV and radio in one room from an easy chair in another room!
I help a 96 year old blinded vet with tech support -- and as his health worsens, needed to make his TV, his radio, and the audio switch that selects what audio should go into his hearing aids via Bluetooth work from his easy chair in his living room. All the equipment is in his bedroom. This IR repeater system installed quickly and easily and works perfectly. Now he can summon ball games, news, or whatever he wants without fear of getting up and falling down. A perfect solution!
