Robooter E40 Folding Electric Wheelchair
Doors and turns
Through older doors, and round in a hallway.
- A standard 32 in interior door leaves 7.4 in to spare.
- An older 28 in door still leaves 3.4 in.
- It turns inside 17.7 in, where the E60 needs 31.5 in and the X40 needs 29.9 in.
- In a hallway or a small kitchen, that means turning instead of backing up twice.
Frequently Asked Questions
-
The Robooter E40 is ideal for users who prioritize easy vehicle transport and a high-tech feel. It is especially well-suited for seniors and active individuals who want a power chair that is easy to manage independently without sacrificing modern conveniences like app connectivity
-
Yes. The E40 is 24.6 inches wide, which fits comfortably through standard interior doorways, and its compact frame is designed for narrow aisles, elevators and tight indoor turns. We recommend measuring your narrowest doorway before ordering.
-
Yes. The E40 uses a two-step manual folding system that collapses it into a suitcase-like shape in seconds. At approximately 55 lb including the battery, it fits easily into most standard trunks or closets
-
Absolutely. The E40 features Bluetooth App Integration, allowing you to "drive" the chair remotely. This is a major advantage for parking the chair in a corner or bringing it to your bedside after you have transferred
-
Yes, with the right battery. The standard 20Ah battery exceeds most airline limits, so Robooter offers an optional 12Ah airline friendly battery for flying. Battery rules vary by airline, so we recommend confirming with your airline before you fly. At 55 lb with a simple two step fold, the E40 is easy to gate check.
