Is a corded upright still worth it, or should I switch to cordless?

For homes with lots of carpet and heavy pet shedding, corded uprights still dominate in expert testing for sustained suction and deep-cleaning agitation. Cordless stick vacuums win on convenience but tend to lose airflow over a 30+ minute session. Reviewers commonly recommend a corded upright as the primary vacuum plus a cordless handheld for quick pickups.
