The 3500 provides far better sound quality than the 2000 although neither is brilliant IMO.

I have two beolab 2000 in the bathrooms. I really like them a lot. The mini control panel is very practical, they have many placing options and can also be used with a remote. I find the sound very impressive for such a small unit and it can play really loud if wanted, without distortion. The price tag is also quite reasonable for B&O standards. For small rooms they are perfect.

Just to make your choice even more difficult...

I got a Beolab 3500 in the dining room (see one of my post for pictures), perfect for background music when we have guests.

Got mine for 300 Euro/240 GBP from ebay... a real bargain... but sometimes you just have to be lucky!

Both are good speakers, but for your Utility-Laundry Room application, I would suggest the 2000.

Easier to clean, robust metal construction, can be mounted or freestanding ( moved as needed ), hand or remote controlled, and is ML linked to certain B&O systems.

I have both in upstairs bedrooms, serving as music, radio, Internet, and SKY TV sound extensions. I one takes a Beo4-Beo 5 along upstairs, it does provide a " Pathway of Sound. " The speakers continue to supplement the recent addition of BV-8, which has very good sound.

Pulling the ML cable is easy, but making the custom lengths and junction box connections required Ye Olde Flyfishing magnifying set for 2 days, and a little patience. Perhaps you will be fortunate and able to use the stock ML cable connectors available through B&0.

I hope this is helpful.

Another useful nugget of information is that BeoLab2000 can be activated by the volume control on BeoCom6000.  If the speaker is in standby mode and you turn the volume wheel on a BeoCom6000 handset, the BeoLab2000 switches the Master on to the last thing it was doing.

As far as I know, the BeoLab3500 doesn't do this.

Given where you say it is being used, I would go for the BeoLab2000.

I'm a fan of both - the BL2000 is more flexible overall, and also cheaper. However, you can't buy them new any more, so the likelihood is that the garuantee is either much shorter or gone alltogether.

BeoLab 3500 is far more discreet, sounds better and will come with the guarantee. However, doesn't offer the same hands-on-control as the BeoLab 2000, which I love! I'm also a sucker for the BL2000's design.
