tldr; Older budget model. Was a solid performer in its day but modern robots have surpassed it. Still works fine for basic cleaning.

What Redditors Say
Best praise vs top criticism for Roborock E4
Best Praise
+1 ptsβFor your home, considering its size and your needs, a robot vacuum with mopping capabilities would be ideal, especially to handle the dust and occasional footprints on tile. Brands like iRobot, Roborock, and Ecovacs offer models across various price ranges that could fit your requirements. For example, the Roborock E4 is a more budget-friendly option with both vacuuming and mopping capabilities, suitable for handling pet hair and light debris.β

Best praise vs top criticism for Eufy RoboVac 30C
Best Praise
+1 ptsβjust doing some research myself for new one. eufy 30c, lasted almost 4 years on the dot, I could probably strip it apart and give it iso bath but i think its time to replace old af, worked on morning shift just fine with minimal maintenance, great for hard floor pet hair, the base sucked, and needed a bunch of room around it and ideally be held in place somehow otherwise robot would move it. never used app if it had one, main quirk about it was strict wifi requirements, it needed 802.11b/g 2.4ghz, it wouldnt work otherwise, whatever wifi chip it had was very old. the sweepers needed replacing every year but are cheap to get and came with a set spare.β

+1 ptsβPretty much anything will be better than your 30C, including modern Eufys. If you're not turned off by them, the C20 is a good budget option, or you could get a S1 for about $600 (per Amazon US) with really good mopping and obstacle avoidance (though some extra maintenance tasks). There are other brands, though. Mova and Dreame are running some good deals right now, with the Dreame L10s family seeing some really good prices. Roborock and Narwal are also brands to consider; Roborock has a reputation for reliability, while Narwal robots mop really well and are excellent at obstacle avoidance. Dreame sells a Tricut Brush add-on (and bundles it with some Dreame and Mova models) that's good for hair. Also look for models with divided main brushes or brushes not attached at one end.β
