Motor Power and Blending Performance
Both carry the same 2 HP motor, and both crushed ice and frozen fruit without slowing down. The 5200 blends so fast that you need low speed for chunky jobs like pesto. The E310 blends smaller batches just as quickly, though thick mixtures may need the tamper.
Blade Design and Jar Capacity
The E310's 48 oz jar suits one to three people, and its blades handle single servings cleanly. The 5200's 64 oz jar pulls big batches into the vortex faster, which is why hot soup finishes in one pass. Both jars are BPA-free Tritan (BPA is the chemical they replace).
Height and Counter Space
The E310 stands 18 in and fits under standard upper cabinets, so it stays on the counter. The 5200 stands 20.5 in and does not fit under most upper cabinets, so ours lives on a cart.
Controls and Preset Programs
Neither machine has preset programs or a timer. The E310 runs 10 variable speeds plus a pulse switch, and the pulse wins the chunky jobs like salsa. The 5200 has a 10-speed dial and a High switch but no pulse function; return the dial to speed 1 before switching it on to prevent splattering. The full rundown lives in the 5200's owner's manual.
Noise Level
Both machines are genuinely loud, and we wait until the kids are awake to blend on either one. Our meter caught the E310 around 88 to 92 dB and the 5200 at 90 to 94 dB at top speed.
Cleaning and Maintenance
Both self-clean in 30-60 seconds with warm water and a drop of dish soap: blend on high, rinse, done. The E310 jar is also dishwasher safe, while the 5200's is not, so the 5200 leans on the self-clean routine.
Durability and Build Quality
Vitamix has built blenders in Ohio for more than 75 years, and that heritage shows in both machines. We have seen daily-use 5200s run for 18 years before the motor gave out; ours also survived a drop onto the floor.
Price, Warranty, and Value
The E310 typically sells for about $379 and the 5200 for about $479 to $500, though street pricing moves week to week. Both warranties are full: 5 years on the E310, 7 years on the 5200, covering parts, performance, labor, and two-way shipping. The E310 saves about $100 up front; the 5200 adds two years of coverage.
