Shark RV2610WA Matrix Plus

Best Buy 1-star review by JasmanyAV (title: "Lucky if you can get more than 6 months of use."). Owner described thin plastic parts cracking and breaking under normal use, improvising temporary fixes while Shark parts were on backorder. They said they were past warranty/exchange time and had to buy replacements from Shark.

Best Buy 1-star review by Mamonte (title: "Keep looking for other options"). Owner called it an expensive gadget with a short lifespan: mopping (liquid feeding) stopped working in five months after previously mopping well.

Best Buy 1-star review by Lisa (title: "Pure disappointment"). The tank button that holds the assembly together broke after four months. Owner spent over an hour on hold trying to get a warranty replacement part and said the robot was unusable as a paperweight while waiting.

Best Buy 1-star review by rayfcy (title: "Defective product, non-existent customer service"). Within a couple of months the gray dust-cup latch snapped under normal use. Multiple warranty-claim attempts to Shark support got no response, so the owner concluded the warranty was useless and would not buy Shark again.
