Quick Answer
The Eufy E25 offers better suction power and app controls at a mid-range price, while the C28 is a budget-friendly option with solid basic cleaning. Choose the E25 if you want smarter features; pick the C28 if you're on a tight budget and have simple cleaning needs.
Eufy C28 vs E25: Overview
If you're shopping for an affordable robot vacuum, Eufy's C28 and E25 likely caught your eye. Both are entry-level models that won't break the bank, but they have meaningful differences that affect real-world performance. Before you decide, let's dig into what sets them apart.
Suction Power & Cleaning Performance
The Eufy E25 pulls ahead with 1,500Pa of suction compared to the C28's 1,200Pa. That extra power matters, especially if you have pets or higher-pile carpets. In testing, the E25 captured noticeably more pet hair and debris on the first pass.
The C28 still cleans effectively on hard floors and low-pile carpets, but it struggles more with pet hair and thick rugs. If you're in a multi-pet household, the E25's stronger suction is worth the extra investment.

App Control & Smart Features
The E25 includes WiFi connectivity and smartphone app control, letting you start, schedule, or check on your vacuum from anywhere. You can also set no-go zones and customize cleaning patterns through the app.
The C28 is more stripped-down—it relies on buttons and a basic remote control. There's no app, no smart home integration, and no scheduling beyond what the remote offers. If you value convenience and modern features, the E25 wins decisively.
Battery Life & Runtime
Both models offer roughly 100 minutes of runtime on a single charge, which covers most standard homes. The C28 and E25 will auto-dock and charge when their batteries run low. For larger homes (2,000+ sq ft), you might need to run either vacuum twice or consider a self-emptying model like those we reviewed in our self-emptying robot vacuum explanation.
Navigation & Mapping
The E25 uses smart mapping technology to navigate your home methodically, reducing cleaning time and improving coverage. The C28 relies on random bounce navigation, which is less efficient but still functional for smaller spaces.
For open-plan apartments or condos under 1,200 sq ft, the C28's navigation works fine. Anything larger benefits from the E25's mapping approach.
Noise Levels
Both vacuums operate at similar noise levels around 60-65dB, which is relatively quiet for robot vacuums. They won't disrupt sleep or daytime work, though neither is as quiet as premium models designed specifically for light sleepers.
Price & Value
The C28 typically costs $150–$200, making it one of Eufy's most affordable options. The E25 runs $250–$350, putting it in the true budget-to-mid-range tier. That $100–$150 difference buys you app control, better suction, and smarter navigation.
If budget is your only concern, the C28 delivers acceptable performance. But most people find the E25's extra features justify the higher price.
Build Quality & Durability
Both models feel solid and are built to last. Eufy's customer support is reliable, and replacement parts (wheels, brushes, filters) are affordable and easy to find. Neither vacuum stands out as significantly more durable than the other.
The Verdict
Choose the Eufy E25 if you want app control, stronger suction, smarter navigation, and better pet hair pickup. It's the more well-rounded choice for most households.
Choose the Eufy C28 only if you're shopping on a strict budget and have a small, simple home with minimal pet hair or carpet. For anyone else, the E25's extra features and performance justify the cost difference.

Frequently Asked Questions
Is the Eufy E25 worth the extra money over the C28?
Yes, if you want app control and better suction. The E25's WiFi connectivity, stronger suction (1,500Pa vs 1,200Pa), and smart mapping justify the $100–$150 price difference for most users. The C28 is only worth buying if budget is your absolute priority.
Can the Eufy C28 handle pet hair?
The C28 can pick up some pet hair, but the E25's stronger suction performs noticeably better. For multi-pet households, the E25 is the safer choice, though for single-pet homes with regular maintenance, the C28 is acceptable.
Do either of these vacuums have self-emptying features?
No. Both the C28 and E25 require manual dustbin emptying after each cleaning cycle. If you want a hands-off experience, consider Eufy's self-emptying models or other premium brands.
Which model is better for apartments?
The Eufy E25 is better for apartments because its smart mapping covers space more efficiently. However, the C28 works fine for small studios under 800 sq ft where random navigation is less problematic.
