Nolvis X1 / Solutions / Comparison

Choosing a Confined-Space CVI Drone? Here's an Honest Comparison

The market leader makes excellent drones. Not everyone needs everything they carry — or the price that comes with it. Here's how to decide.

The established caged-drone platforms are serious products: robust, mature software ecosystems, LiDAR-based 3D mapping. If you need full-featured point clouds and have the budget, they deserve a place on your shortlist.

But not everyone needs LiDAR-first workflows. And not everyone has $50,000–$150,000+ to spend. If you're comparing your options, you're probably in one of these situations:

This page gives you a fact-based comparison so you can make the right call.

The End-of-Life Problem — an Important Factor

The compact caged drone that many inspection teams standardized on has been discontinued by its manufacturer. If you're running one and looking to replace or supplement it, your options are:

  1. Upgrade to the current flagship: a significant price jump — and a larger 20-inch-class frame that cannot fit through some 18-inch access points the older compact model could enter.
  2. Choose a different CVI drone: this is where the X1 enters as a direct consideration.

For CVI-centered programs, the X1 is the most direct functional equivalent — at less than one-third the price of the flagship path — and it still delivers an onboard LiDAR 3D point cloud (200,000 points/s) alongside the visual inspection. If survey-grade, downward-focused 3D volumetrics are your primary deliverable, evaluate the flagship's mapping suite against that specific requirement.

Access Size: The 14-Inch vs. 20-Inch Difference

This is a practical consideration that often drives the decision. Current 20-inch-class systems require larger openings to pass through. If your facility has access points of 18 inches or smaller — standard tank manways, boiler ports, older industrial installations — those systems physically cannot enter them. The X1, at 14-inch class, can.

One documented example: at a major US refinery with standard 18-inch manhole access, the 20-inch-class system could not pass through. The X1 could — validated on-site. For facilities with constrained access geometry, this is a binary decision point, not a preference.

What You Get

The X1 system includes the aircraft, tablet controller, and Nolvis Cloud reporting. Nolvis Care maintenance coverage ($4,000/year) adds parts and cage replacement, loaner unit access up to 3×/year, and technical support. Dual-unit packages with extra batteries and range extenders are available for fleet programs.

For inspection service companies, the economics are particularly clear: the X1 can be deployed on a single client engagement, billed against that project, and recover its cost before the second inspection begins. Pricing is set by Nolvis and authorized distributors — request a quote.

Frequently asked questions

Is the X1 comparable to the compact legacy caged inspection drones?

For CVI (close visual inspection) workflows, yes. The X1 is positioned as a CVI-focused drone in a similar size and capability range to the discontinued compact-class systems, at a significantly lower price point — a natural evaluation point for teams looking to replace or supplement their fleet.

What's the main difference between the X1 and full-featured legacy systems?

Price (less than one-third the cost), frame size (14-inch class vs. 20-inch class), and focus. The X1 is CVI-first with an onboard LiDAR point cloud included; legacy flagships are LiDAR-first full-feature platforms. For operations centered on visual inspection, the X1 delivers the core function — plus 3D context — at a fraction of the cost.

Can the X1 pass through access points that larger caged drones cannot?

Yes. The X1 is a 14-inch-class drone that passes through openings as small as 16 inches — including standard 18-inch manways where 20-inch-class systems cannot fit. For facilities with constrained access points, the X1 can enter spaces larger drones cannot.
