-
Provides excellent cleaning on thicker carpets, with its powered head and strong suction working effectively even on shag and other high-pile surfaces.
-
The 600 Series delivers strong suction in the low-20s kPa range and, when paired with its powered head, provides robust real-world pickup and deep carpet cleaning that closely matches the 200 Series.
-
On medium pile carpet, the 600 Series delivers solid cleaning power and handles fine sand very well—matching the 200 Series in tests—though its older powerhead design can snowplow cereal and leave a bit of cat litter and pet hair behind compared with the best-engineered canister heads.
-
Controls on the 600 Series are straightforward, with a clearly labeled carpet and hard floor switch and an on handle variable speed dial that make it easy to change power and floor type while you clean.
-
For pet owners, the 600 Series combines decent pickup from its main powerhead with a dedicated Pet Powermate tool that can deep clean cat trees and upholstery better than most cordless tools, though hair still tends to wrap on the main brushroll and some units report the small powered tool stalling or failing over time.
-
The 600 Series offers a generous tool set that includes a dusting brush, crevice tool, Pop N Go floor tool, and a powerful Pet Powermate upholstery tool that can deep clean pet furniture, but the hard floor head is undersized and uses a proprietary fitting and the small powered tool has been reported to stall and even fail early, so overall versatility is tempered by some design and reliability compromises.
-
The 600 Series includes a retractable cord that winds fully into the canister to cut down on cord clutter, and while its spring feels stronger than on the 200 Series the rewind is still slow, requires holding the pedal, and works best when the cord is pulled completely out first, so cord management feels more fussy than on many competitors.
-
Although the 600 Series continues a long running Kenmore canister design and some users report many years of use, technicians point out taped together internals, non modular wiring that limits the number of viable repairs, and accessory tools that can fail early, suggesting that long term durability and serviceability are more modest than its heritage alone would indicate.
-
While the 600 Series uses a multi-stage bag and HEPA exhaust layout that performs like a truly sealed system in recent leak tests and keeps fine dust inside the canister, technicians have noted that the bag and housing do not always form a perfect seal and cabinet dust can build up over time, so real-world filtration is excellent overall but not flawless.
-
Often selling under three hundred dollars, the 600 Series can represent fair value for shoppers who catch it on sale and want more power and pet tools than most big-box vacuums, but reviewers note that the 200 Series delivers similar cleaning for less and that better-built, more pleasant-to-use canisters in the five- to eight-hundred-dollar range usually justify their higher prices.
-
Overall, reviewers see the Kenmore 600 Series as a powerful but flawed canister that offers strong suction, a useful Pet Powermate, and respectable cleaning for the price yet suffers from extra weight, leaky-feeling ergonomics, and weaker accessories than ideal, making it a reasonable option on sale for pet owners who value its tools but a less compelling choice than the better-value 200 Series or more polished high-end canisters.
