The main difference between Shark UR2500SR, RV2502AE, AV2501AE, AV2501S, AV2511AE is the self empty base and side brushes.

Self Empty Base
UR2500SR and AV2501S come with a Self-Empty Base which has 30-day capacity.

The RV2502AE has different versions, the old version has two side brushes, the new version has only one side brush plus a blower, the blower which called CleanEdge use blast of air to help remove debris from corners and edge. So, don’t be surprised if you get the one with only one side brush.
The AV2501AE has two side brushes. It seems that there is no AV2501AE new version on the market yet at this moment.
The difference between the RV2502AE old version and the AV2501AE is only the color scheme.

Difference between Shark RV2001WD (AI) vs RV2610WD(AI Ultra)

Matrix Clean Navigation vs Row by Row Cleaning
The RV2610WD and other RV2600 series robots use Matrix Clean Navigation which enable the robots to clean from multiple angles in a matrix-like grid ensuring no spots are missed and a deeper clean on carpets and floors.
While the RV2001WD cleans in a row by row pattern.

Edge Cleaning
The AI Ultra robots have single side brush at the bottom but added the CleanEdge Technology which use blasts of air and corner recognition to help remove debris from edges and corners. While the AI models use two side brushes.

Ultra Mop
The AI ultra has the Ultra Mop setting in the app, according to Shark, this setting makes RV2610 get 50% better stain cleaning in targeted zones (vs. RV2001WD, modified IEC 62885-6).

Shark AV2001WD vs RV2001WD
According to Shark customer support, the difference between the Shark RV2001WD and AV2001WD is where the unit is sold, and what accessories are included.

The main difference between the AI Robot and AI Robot Vacmop/Vacmop Pro is:

the Vacmop and Vacmop Pro feature sonic mopping function to mop hard floors whereas the basic AI Robot does not have this feature.
You cannot buy the AI Robot R201/RV2001 and R211/RV2011, then add the fluid reservoir later. Because the AI Robot is not compatible with fluid reservoir.
The Vacmop can only wet mop hard floors, but cannot wet clean carpets.
The robot has the ability to detect carpets and rugs.
You can activate the Carpet Detection in the app when it mops to stop it from moving onto carpets and rugs, or set up no-go zones in the app.

According to product specifications on Shark official site, the AI Robot dust bin capacity is 0.33 quarts versus 0.27 on the vacmop and vacmop pro.
And the AI robot weighs 7 lbs versus 7.6 lbs on the vacmop and vacmop pro.

What’s new on these Shark AI robots?
The Shark AI robots adds the new AI Laser Vision which claimed to be Shark’s most advanced vision module. It enables the robot to detect and avoid obstacles, and respond to no-go zone you set up in the app. Unlike the previous robot versions, it does not require the physical boundary strip to keep the robot out of certain areas. The Vacmop models also feature sonic mopping which scrubs hard floors 100 times per minute. You can not schedule the vacmop robot to dry vacuum first then wet mop. It vacuums and mops simultaneously when the fluid reservoir and mop pad attached. To vacuum only, the fluid reservoir must NOT be attached to the robot. And it does not mop only.
And according to Shark, the AI Laser Vision is not dependent on ambient lighting and can navigate your home at night or in low lighting conditions. Previous series robots needs light to know where they are going, if clean in dark areas, they cannot clean properly in a row by row way.

Some questions and answers:

• Do they clean randomly or methodically?
  They clean row by row methodically.
• Do these Shark AI robots have the self empty feature like the IQ self empty robot?
  No. The Shark AI robots is not compatible with the self empty base.
• Can you use it to clean a multiple story house?
  It can only map one floor. You would need to manually move it to another floor. When the Robot is low in battery, you would need to manually put the Robot on the charging dock to recharge.
• Do they return to charge automatically and resume cleaning?
  Yes. As long as you use them on one level, and follow the user guide, these things should be done automatically.
• Do they include boundary strip so that you can stop them from entering no go zone?
  No. These AI robots now support virtual no go zone, so they do not need the boundary strip anymore.
• Do they work without internet connection?
  Yes. But any features that require Wi-Fi will not work.
• How tall are these vacuum robots?
  They are 3.48-inch in height.
• With the AI robot vacmop, can you set it to vacuum only?
  It will not mop hard floors unless you attach the fluid reservoir.
