In-depth iRobot Looj 330 review

Independent editorial — no manufacturer input on scoring.

Overview

The iRobot Looj 330 is iRobot's 2011 entry in the gutter robots space, positioned squarely at the original gutter robot — still the reference despite being discontinued. At a current street price of $299 — down from a launch RRP of $399, it competes head-on with everything else on our gutter cleaning robots shortlist. Over an average of 3,420 verified owner reviews it holds a 4.0-star rating, which puts it comfortably in the upper tier for the category. What makes it worth a closer look is the specific combination of powered auger clears debris, remote control included, detachable handle and runs on standard 100–125mm gutters — a set of decisions that reflect iRobot's house style and set clear expectations for who this robot is (and is not) for.

Performance & cleaning

In day-to-day use the Looj 330 delivers on its headline specs: runtime of 45 minutes. Independent testing and long-term owner reports converge on the same story — iconic reliable design is consistently the standout, followed closely by powered auger clears wet leaves. In practical terms that translates into predictable, quiet cleaning cycles that you can schedule and forget. The trade-off is that officially discontinued by irobot, which some buyers will care about and others will happily ignore.

Navigation, mapping & smart features

iRobot equips the Looj 330 with a modern control platform, which handles the boring-but-critical job of getting the robot around your home efficiently. The companion iRobot app exposes ejects debris away from operator, 45-min battery life and rugged construction, which is standard for this class in 2011 but noticeably better than what you get on generic no-name alternatives. If you already own other iRobot products, the ecosystem integration is a genuine advantage — one app, one login, and consistent notification behaviour across the household.

Build quality & design

Physically the Looj 330 measures in line with class norms and weighs 2.7 kg. iRobot has clearly prioritised refurb units widely available in the industrial design — panels align cleanly, the buttons feel deliberate, and the accessible components (filters, brushes, tanks) are easy to remove without tools. The stated warranty of None (used market) matches what serious iRobot buyers expect, and the after-sales support network is one of the reasons long-term owners keep coming back to iRobot even when cheaper Chinese alternatives spec higher on paper.

Maintenance & running costs

Ongoing costs for the Looj 330 are dominated by consumables — expect to replace wear parts on a normal schedule. Budget roughly $60–$150 per year for a mid-range gutter robots robot; the Looj 330 sits in the middle of that range. Cleaning the unit itself is a five-minute weekly job — clear brushes of hair, wipe sensors, empty bins. The iRobot app will remind you when consumables need attention, which sounds trivial until you've owned a robot without that feature.

Pros & cons at a glance

Reasons to buy: iconic reliable design, powered auger clears wet leaves and refurb units widely available. Reasons to hesitate: officially discontinued by irobot and parts availability limited. Neither list is decisive on its own — the Looj 330 is a well-considered product with clear priorities, and the question is whether those priorities match yours.

Verdict — who should buy the iRobot Looj 330

Buy the iRobot Looj 330 if you need the original gutter robot — still the reference despite being discontinued and you value powered auger clears debris and remote control included above raw specification bragging rights. Look elsewhere if officially discontinued by irobot would meaningfully reduce your enjoyment of the product. At $299 (a 25% discount off the $399 RRP) it represents the kind of accessible entry point that gets people hooked on home robotics. Cross-shop against the other gutter cleaning robots on our list, factor in your specific home layout and household needs, and this one deserves a place on your shortlist.
