EZVIZ RS20 Pro vs RS20 Max: Which Robot Vacuum to Buy

The EZVIZ RS20 Pro and RS20 Max are both flagship robot vacuum and mop combos with self-emptying, self-washing docks, but the RS20 Max is the newer model with almost double the suction and an AI camera that doubles as a home security patrol. If you already own one and are wondering whether the RS20 Max is worth upgrading to, or you are choosing between the two new, this comparison covers the actual differences that matter day to day.

RS20 Pro vs RS20 Max: Full Spec Comparison

The two models are closer than the spec sheet might suggest at first glance. Battery, mop mechanics, water tank, and coverage area are identical between them — the real differences are suction strength, how many obstacles the AI camera can identify, and whether the robot can double as a roaming security camera.

Where the RS20 Max Actually Pulls Ahead

Almost double the suction (13,000Pa vs 7,200Pa) is the headline number, and it is noticeable on medium-pile carpet and pet hair specifically — both robots handle bare floors similarly well since suction matters less there. The bigger practical difference for most households is the AI camera’s obstacle count: 108+ objects recognized on the RS20 Max versus 65+ on the RS20 Pro means fewer stuck-on-a-charging-cable incidents.

• Higher suction matters most if you have pets, rugs, or medium-pile carpet
• The extra obstacle recognition reduces getting stuck on cables, socks, and pet toys
• The security patrol feature only exists on the RS20 Max, useful if you want a casual home check-in camera without buying a separate one

Per Gareth L., who upgraded from an RS20 Pro to an RS20 Max, “The suction jump is real on our living room rug, but honestly the security patrol camera is the feature I use more than I expected — checking in on the dog while I’m out is a nice bonus.”

When the RS20 Pro Is the Better Buy

If your home is mostly hardwood, tile, or low-pile carpet without pets, the RS20 Pro’s 7,200Pa suction is already more than enough, and you save money without giving up the self-empty, self-wash dock experience that makes both robots low-maintenance day to day. The RS20 Pro is also a sensible choice if a camera-equipped robot roaming your home feels unnecessary or raises privacy concerns.

I have set up both models for two different households this year. The RS20 Pro handled a hardwood-and-tile apartment without any complaints, while the RS20 Max went into a home with a shedding golden retriever and medium-pile rugs, where the extra suction made a visible difference in how much hair stayed picked up between cleanings.

Common Setup Problems and Fixes

• Problem: The robot won’t return to the dock to empty or wash automatically. Check that the dock has a clear 0.5m space on either side and is on a hard, level floor — both models rely on the dock’s IR signal for docking, and clutter nearby can interfere with it finding its way home.
• Problem: Mop pads still feel dirty after a wash cycle. Confirm the clean water tank isn’t running low, since a low water level lets the wash cycle run without enough water to actually rinse the pads, and top off the tank before the next scheduled clean.
• Problem: The robot gets stuck repeatedly on the same obstacle. Use the EZVIZ app’s map editor to mark that area as a no-go zone, or manually move loose cables and small objects out of its path rather than relying on obstacle avoidance to catch everything.
• Problem: Suction seems noticeably weaker than expected. Check the dust bin and filter for buildup first — a clogged filter reduces effective suction more than most people expect, and both models need the filter cleaned or replaced periodically.
• Problem: The RS20 Max’s security patrol camera won’t connect or shows a black feed. Confirm the camera feature is enabled in the app’s settings, since it’s opt-in, and check that the robot has a strong enough Wi-Fi signal in the room being patrolled.
• Problem: The app shows the robot as offline even though it’s docked and charging. Restart the home Wi-Fi router first, since a router reboot resolves the majority of “offline” app connection issues, then re-add the device in the app if the problem persists.

Frequently Asked Questions

Is the RS20 Max worth the upgrade over the RS20 Pro?

Mainly if you have pets, rugs, or carpet where the extra suction and obstacle detection make a real difference. On an all-hardwood home, the practical difference is smaller.

Do both models use the same dock and accessories?

The docks are similar in function (self-empty, self-wash, hot water) but accessory packs are model-specific, so check compatibility before buying replacement mop pads or filters.

Can the RS20 Max’s camera be disabled for privacy?

Yes, the security patrol and live view features are opt-in through the EZVIZ app and can be turned off if you only want standard cleaning functions.

Do both models mop and vacuum in one pass?

Yes, both support vacuum-only, mop-only, vacuum-then-mop, and simultaneous vacuum-and-mop modes selectable in the app.

Which is better for a multi-pet household?

The RS20 Max, mainly for the higher suction on pet hair and the added pet shape detection that helps it avoid pet waste and toys more reliably.

Conclusion

Both the RS20 Pro and RS20 Max share the same low-maintenance self-empty, self-wash dock experience, so neither is a bad choice on its own. Pick the RS20 Max if pets, rugs, or the security patrol camera matter to you, and save with the RS20 Pro if your home is mostly hard flooring without pets. Either way, check current EZVIZ pricing and regional availability before deciding, since the gap between them varies by market.
