In short: what each side says
Buyers · Brand claims — each opened up in full further down ↓
Owners appreciate the mapping and room-selection features, but widespread hardware failures, unreliable app connectivity, ineffective mopping, and poor value at premium pricing divide satisfaction sha
The cordless design claim holds up as a basic specification. However, the wet/dry capability is undermined by widespread owner complaints about ineffective mopping performance (2.2/5 rating). Pet-friendliness, voice assistant support, and tank capacity are not addressed in the available review data. The broader picture shows significant reliability and durability issues (1.8/5) and poor value perception that overshadow the marketing pitch.
All sides but one land high — Trust it — with one check: owners score reliability & durability weakest.

In their words
“We picked up this iRobot Roomba because Sam's has the best prices in the world. The reviews pre-purchase were pretty solid. We did not get one with an automatic Dust Bin emptier because it doubles the unit cost and adds paper bags that you have to buy, throw away and replace $$. For all of its smarts, it does some wonky things like going into areas it's not supposed to after you've created Spaces/”

“There's a reason it's discounted this much! I've had this model for over a year now and it is an absolute nightmare. It almost never works properly and in the rare case it should work for a short time, the mop feature is pointless since the tiny mop pad just pushes dirt around.
