Many have bag issues/user error with kenmore/miele/sebo which reflects in reviews. Have just changed 1 bag in a kenmore myself with no issues - thinking overfilling and not seating the bag correctly is whats causing 2 issues for many. Bag changing etc is not something to do carelessly in any vac but can prove to be too difficult of a task for many which is no suprise with how enept the population is with basics.
Get a bagged kenmore canister.
Everyone says Shark. I had many Shark vacuums. The filters suck. The canisters suck. The brush rolls suck. When they broke or died it was impossible to find anyone who was willing to repair them. I decided to switch to a bagged canister style vacuum. I started with a kenmore because I wasn’t sure I’d like the canister style and Kenmore vacuums are fairly inexpensive. I really liked it. Although it was super heavy. The bags are much cleaner and easier to deal with than the shark canisters. One bag lasts a week or more which means I’m not dumping the canister multiple times during one clean. Filters don’t get as dirty. The Kenmore died after a year but I was able to get it repaired for cheap enough (was a fuse or something). I saved up $ and bought a Miele bagged canister style vacuum and I love it so much. Superior suction. Superior filtration. Light weight. Will never go back to the crappy shark vacuums. I’m a Miele for life. And I can get it repaired or serviced at my local vacuum repair place. I probably spent as much on all the sharks I bought as I did on the Miele.
Unfortunately you’ve come to the realization that a lot of Kirby owners do. Unless you have wall to wall carpeting there not much use. I’ve had several dyson’s they’re ok. I have a strong preference for a bagged canister vacuum such as a Kenmore, especially for shag, the power head is light and won’t bog down. Some have adjustable suction as well. Meiles are really good and quiet just make sure you get a powered brush not a turbo or air driven.
I’ve had a bunch of vacuums over the years and I’m always happiest with a bagged canister. To me it seems like less work because your moving the canister maybe every 4 passes vs the whole thing every pass with an upright. I have a Kenmore that works really well that I got on marketplace for $40 5 years ago.
I've had bagless uprights for 20+ years and recently realized how bad they are for my allergies. I bought a bagged Riccar upright and a Kenmore bagged canister. The amount of dirt that is coming out of my carpet is amazing. The bags are so different than they used to be. Now they are HEPA. Bagged from now on.
I own 2 regular kenmore corded canister bag vacuums bought for \~$320 each. The vacuum rolls around following you. They have a beater head for carpet and another for hardwood. Nothing fancy, but both heads and arms go flat to allow you to vacuum under furniture. The suction is scary strong and they have not had any problems for the past 20 years. They will try and suck up anything in or near their path.
Just don't by a stick one - useless. Get either an upright or a canister corded one - maximum real suction power. I have 2 canister corded vacuums, Kenmore and Panasonic, one for each floor level of our home. Work perfect for hardwood and carpeted.
I have a Kenmore canister and the Panasonic equivalent both for 25+ years running fine. Nothing has every broken so parts are no concern. Just replaced the filters every 10 years or when my brain reminds me :D.
Sorry, you don't want corded canister. We've had 2 Kenmore canisters for 25 years, 2 story, 2500 sq ft. and they work wonderfully.
