Robot Vacuums for Small Apartments: Dock Size and Navigation Compared

This one leads the group on stated suction at 25,000Pa, paired with an extendable side brush and a mop that lifts 10.5mm to clear rugs. Its dock is described as all-in-one, handling both emptying and cleaning duties, which likely makes it the largest footprint in this lineup. The listing calls out obstacle avoidance and app control but doesn't specify the navigation technology behind it, so buyers who want a named mapping method should compare that gap against the LiDAR-equipped options here.

Roborock's listing is explicit about PreciSense LiDAR navigation, which is a firmer claim than most of the others make about how the robot finds its way. Self-emptying is rated up to 7-9 weeks, a middle-of-the-pack interval, and a dual anti-tangle system is called out specifically for pet hair and carpet. It's positioned as an upgrade from an older Q5 Max+, which suggests incremental refinement rather than a from-scratch redesign.

The listing names a 'Laser Navigator with Smart Mapping' and lists 8000Pa suction alongside a 150-minute runtime, scheduling, and Alexa app control. It's self-emptying, though the listing doesn't state how many days or weeks that interval covers, so buyers can't compare its dock capacity against the others on that measure alone. It reads as a straightforward, feature-complete entry without the extras — no mop-lift height, no anti-tangle system — called out elsewhere.

Shark's listing states a 60-day bagless self-empty base, the longest interval given in exact days among these six, plus 360° LiDAR home mapping and a self-cleaning brushroll. It's described through Matrix Clean and works with Alexa, but the title makes no mention of mopping at all, so treat this as a vacuum-first pick. No suction figure appears in the listing, which is worth noting if that number matters to you.

Lefant's listing claims 120-day self-emptying, the longest stated interval of any product here, alongside 18,000Pa suction and an auto mop wash-and-dry cycle. Its navigation is described as PSD 2.0 smart obstacle avoidance rather than named LiDAR, so route planning is less explicitly specified than on the Roborock or Shark listings. Dual-band WiFi support is called out, which is a small but real convenience during setup.

Tikom's listing is the simplest of the six: 5000Pa suction, a 150-minute max runtime, app and remote control, and self-charging — but no mention of a self-emptying dock or a named navigation system. That likely means a smaller footprint by default, since there's no emptying base to house, but it also means more manual bin-dumping for the owner. It suits a buyer who wants a basic vacuum-and-mop combo without dock-related complexity.
