Robot vacuums have become one of the most talked-about home appliances in recent years - but with prices ranging from a few hundred dollars to well over $3,000 NZD, it's fair to ask: are they actually worth it? We've broken down the real pros, cons, and what to look for so you can make a smart call.

What Do Robot Vacuums Actually Do Well?

The honest answer: maintenance cleaning. If you run a robot vacuum daily or every couple of days, your floors stay consistently clean with zero effort on your part. That's genuinely valuable - especially for pet owners, households with kids, or anyone who just doesn't want to think about vacuuming.

Modern models like the Dreame Aqua10 Ultra Track S and the Eufy E28 Omni also mop, self-empty, self-wash their mop pads, and refill their water tanks automatically. Once set up, you can genuinely go weeks without touching them.

Where They Fall Short

Robot vacuums aren't a replacement for a full deep clean. They struggle with thick rugs, heavily cluttered floors, and stairs. They also need their sensors, brushes, and dustbins maintained regularly - and the better the robot, the more consumables you'll be buying over time. Don't assume "robot" means zero maintenance.

Track-based robots like the Dreame Aqua10 Ultra Track S have largely solved the rug and obstacle problem at the flagship end - but at $3,497, that capability comes at a price. For most NZ homes, a mid-range model with good LiDAR mapping will handle 90% of the floor area reliably.

Which Robot Vacuum Is Right for You?

The right model comes down to your floor types, how much automation you want, and your budget. Here's a breakdown by category using what's currently in stock at Tech Supply Shed NZ:

Best Entry-Level Value - Tapo RV20 Max Plus ($447)

The Tapo RV20 Max Plus is the starting point for most NZ households. LiDAR navigation, vacuum-and-mop combo, and a genuinely competitive price make it the easiest recommendation at the entry level. It won't self-empty, but for the price that's a reasonable trade-off. The Tapo RV20 Max ($479) is the TP-Link branded version of the same platform - worth comparing if pricing shifts.

Best Mid-Range Step-Up - ECOVACS DEEBOT T50 Pro Omni ($798)

The ECOVACS DEEBOT T50 Pro Omni brings the full self-maintaining dock experience under $800 - self-emptying dustbin, mop washing, and hot-air drying. ECOVACS' OZMO mopping system is one of the more capable on the market, and the T50 Pro Omni's obstacle avoidance handles typical household clutter well. A strong pick for households with a mix of hard floors and medium-pile carpet.

Best Premium All-Rounder - Eufy E28 Omni

The Eufy E28 Omni is Eufy's flagship all-in-one: powerful suction, full self-maintaining dock, and Eufy's well-regarded app and mapping. Eufy builds some of the most reliable hardware in the robot vacuum category, and the E28 Omni sits at the top of their lineup. If you want a premium experience without going to the Dreame flagship tier, this is the one to look at.

Best Flagship - Dreame Aqua10 Ultra Track S ($3,497)

For those who want the absolute best available in NZ right now, the Dreame Aqua10 Ultra Track S is in a category of its own. Track-based navigation means it can handle thick rugs and obstacles that stop standard wheel-driven robots. It mops, self-empties, self-washes, and navigates more complex floor plans than any other model in our range. At $3,497 it's a serious investment - but for the right household, it genuinely earns it.

Specialist Pick - ECOVACS Winbot W2 Pro Omni ($1,198) - Window Cleaning Robot

Not a floor robot - but worth calling out. The ECOVACS Winbot W2 Pro Omni is a robotic window cleaner that scrubs, rinses, and dries glass surfaces autonomously. If you have large windows or glazing that's a pain to keep clean, it's a genuinely useful complement to a floor robot.

How to Choose: Key Specs to Look For

Suction Power (Pa)

Measured in Pascals. Entry models typically run 2,000-4,000 Pa. Premium models push 8,000-12,000 Pa. For mostly hard floors, 3,000+ Pa is plenty. For carpet, aim for 5,000+ Pa. Higher suction also means louder operation - worth considering if you run it overnight.

Navigation - LiDAR vs Camera

All models currently stocked at Tech Supply Shed use LiDAR navigation, which is the gold standard. LiDAR uses laser mapping to build an accurate floor plan, works in complete darkness, and handles furniture rearrangements reliably. Camera-only navigation is cheaper but less consistent - it's not represented in our current range.

Self-Empty vs Manual Empty

Self-emptying docks add cost but dramatically reduce how often you need to touch the robot. If you're running the robot daily, a self-emptying dock is worth the premium - the bin only needs emptying every 30-60 days. Entry models like the Tapo RV20 range require manual bin emptying after each run.

Vacuum-Only vs Vacuum + Mop Combo

Every active model in our current range offers vacuum-and-mop combo functionality. The quality of mopping varies significantly - basic models drag a damp pad, while premium models like the ECOVACS T50 Pro Omni actively scrub and self-wash the mop pad between passes.

Consumables and Running Costs

Factor in ongoing consumables: side brushes, main brush rolls, filters, mop pads, and dustbags (for self-emptying models). Dreame and ECOVACS accessories are available at Tech Supply Shed - Dreame accessories kits and Dreame floor cleaner solution are stocked alongside the robots.

FAQ - Robot Vacuums NZ

Do robot vacuums replace a traditional vacuum cleaner?

Not entirely - but they dramatically reduce how often you need one. Robot vacuums are excellent for daily maintenance cleaning, keeping floors consistently tidy with no effort. For deep cleaning, moving furniture, or cleaning stairs, you'll still want a traditional vacuum. Most households with a robot vacuum find they only pull out the upright every 2-4 weeks rather than weekly.

Are robot vacuums worth it for pet owners?

Yes - pet hair is one of the strongest use
